     TECHNICAL FIELD 
     The present disclosure generally relates to structural members and beams, and more particularly relates to vehicle components, such as for use as structural and reinforcement beams on vehicle frames or associated vehicle assemblies. 
     BACKGROUND 
     Vehicles, such as automobiles, typically have a rigid structural frame or body structure, which is commonly referred to as a body-in-white or a body-in-black. The vehicle frame or body structure is designed to undergo and absorb certain levels of impact forces, such as to meet insurance requirements and other regulatory and legal requirements. With respect to impact reinforcement and structural beams used in a vehicle body or frame, it is generally known that these beams can be reinforced, such as with more robust reinforcement beam structure or with reinforcement interior inserts to increase stiffness, such as tubular reinforcement inserts or bulkhead reinforcement inserts. 
     SUMMARY 
     The disclosure provides a vehicle structural component, such as a rocker component, that includes a multi-hollow reinforcement beam. The reinforcement beam may include a beam portion having a multi-hollow cross-sectional shape and at least one flange portion that integrally extends from the beam portion. The reinforcement beam may be formed with a metal sheet, such as by roll forming the sheet to have a multi-hollow cross-sectional at the beam portion and to have the flange portion integrally extending from the beam portion, such as at an edge of the metal sheet. The reinforcement beam may extend along the vehicle component or may be disposed at a desired section of the vehicle component to reinforce the respective section of the vehicle component and optionally replace adjacent components of the vehicle component. The vehicle component may be a rocker component, such that the flange portion or portions of the reinforcement beam may be attached to a vehicle structure, such as to the frame, door sill, sills, floor, pillars, crossmembers or like components. 
     According to one aspect of the disclosure, a rocker component for a vehicle includes a reinforcement beam that has a metal sheet formed with a cross-sectional shape extending continuously along a length of the reinforcement beam. The reinforcement beam has a beam portion and a flange portion integrally extending from the beam portion. The flange portion integrally extends from the beam portion and includes an edge of the metal sheet. The beam portion has a multi-hollow shape that encloses a plurality of hollow cavities that extend longitudinally between openings at opposing ends of the reinforcement beam. The rocker component also has a bracket with a first section joined to the beam portion of the reinforcement beam and a second section integrally extending from the first section away from the beam portion. The rocker component further includes a sill panel that has upper and lower flanges extending longitudinally along upper and lower edges of the sill panel relative to the vehicle. The flange portion of the reinforcement beam is joined to one of the upper and lower flanges of the sill panel. The second section of the bracket is joined to the other one of the upper and lower flanges to secure the reinforcement beam to the sill panel in replacement of a separate second sill panel. 
     According to another aspect of the disclosure, a rocker component for a vehicle includes a reinforcement beam that has a metal sheet shaped with a plurality of elongated bends extending in parallel along a length of the reinforcement beam that together form a cross-sectional shape that extends continuously along the length of the reinforcement beam. The cross-sectional shape of the reinforcement beam includes a beam portion and a flange portion that integrally extends from the beam portion. The flange portion integrally extends from the beam portion and extends continuously along the length of the reinforcement beam. The beam portion has a closed cross-sectional shape that encloses at least one hollow cavity that extend longitudinally between openings at opposing ends of the reinforcement beam. The rocker component also includes a sill panel that has flanges extending longitudinally along upper and lower edges of the sill panel relative to the vehicle. The flange portion of the reinforcement beam is joined to one of the flanges of the sill panel to secure the reinforcement beam to the sill panel in replacement of a separate sill panel outer. 
     Each of the above independent aspects of the present disclosure, and those aspects described in the detailed description below, may include any of the features, options, and possibilities set out in the present disclosure and figures, including those under the other independent aspects, and may also include any combination of any of the features, options, and possibilities set out in the present disclosure and figures. 
     The details of one or more implementations of the disclosure are set forth in the accompanying drawings and the description below. Other aspects, advantages, purposes, and features will be apparent upon review of the following specification in conjunction with the drawings.

     DETAILED DESCRIPTION 
     Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle component is provided for a vehicle  100 , such as for a body structure or frame  101  as shown in  FIGS. 1 and 2 . The vehicle frame  101  and associated components may have various designs and configurations, such as for different styles and types of vehicles. As shown for example  FIGS. 1 and 2 , the vehicle component may be implemented as a rocker component  102 , among other vehicle components, such as a B-pillar  103 , a hinge pillar  104 , a floor crossmember  105 , a roof bow  106 , or a header  107 , among other conceivable vehicle structural components. Also, the vehicle may be partially operated by a propulsion system that uses a battery, such as a traction battery or battery modules, which may be supported in a battery tray generally located between the axles and near the floor of the vehicle to distribute the battery weight and establish a low center of gravity for the vehicle. For example, as shown in  FIGS. 1A and 1B , the multi-hollow vehicle component may be a rocker component  102  (e.g., as further shown in  FIG. 16 ) that is disposed alongside a battery tray  108  with the floor crossmember  105  being attached to the rocker component  102  so as to span laterally over the battery tray  108 . Accordingly, the vehicle component in additional implementations may also or alternatively be provided as a battery tray frame component, such as a longitudinally oriented side wall section  109  of the battery tray. Further, the vehicle component may be embodied as the entire piece or as part of the respective vehicle component. 
     The vehicle component may be used, for example, as a structural component or a battery tray component and as such may be designed to undergo various impact forces and to support and sustain different loading conditions. When designing the vehicle component with the reinforcement beam disclosed herein, the outer dimensions of the vehicle component may be reduced and the overall weight of the vehicle component may be reduced while meeting the required impact and loading conditions. The reinforcement beam may span a partial section of the vehicle component or the entire length of the component, such as to extend beyond the component into and to also reinforce an adjacent component. The reinforcement beam disclosed herein may comprise the entire vehicle component or may be joined to additional reinforcements or parts of the vehicle component, such as at desired sections of the vehicle component. For example, the integral flange portion of the reinforcement beam may attach to a sill panel without adding significant processing steps, such as by not needing to include access holes in the sill panel of a rocker component, as is commonly done to access an interior welding location of an insert of a rocker section. Also, a flange attachment of the reinforcement beam to the vehicle component may allow for easily accessible spot welding to attach the reinforcement beam to a sill panel of the vehicle component, which may eliminate or reduce reliance on more expensive welding techniques, such as laser welding or MIG welding within a hollow component. Moreover, the reinforcement beam disclosed herein may be formed with a sheet material, such as by roll forming a metal sheet, to provide the beam with a relatively high strength (for shear and axial loading) and low weight in comparison to common rocker panels, such as to allow the still panels of the corresponding vehicle component (if provided) to use less material, occupy a smaller packaging space, and have greater flexibility in the outer shape design. 
     The cross-sectional shape of different examples of the vehicle component and reinforcement beam may include various shapes and thicknesses for the desired application of the vehicle component. The vehicle component may also include a sill panel or panels, such as sill inner and sill outer panels that attach together around an interior area, where the terms “inner” and “outer” are made in reference to inboard or inward facing and outboard or outward facing directions on the vehicle, such oriented in  FIG. 1 . Unless specified to the contrary, it is generally understood that additional implementations of the rocker component may have an opposite orientation from the examples shown and described, such as where the sill panels identified as an inner panel may be used as the outer panel and the sill panels identified as an outer panel may be used as the inner panel. The cross-sectional shape of the inner and outer panels may vary along the vehicle component, such as, for example, by flaring outward at the ends (as may be used for B-pillar implementations). The reinforcement beam may have a multi-tubular shape that has two or more hollow interior areas that extend within the interior area of the vehicle component. The cross-sectional shape or profile of the reinforcement beam may generally have a consistent shape along the length of the reinforcement beam, such as to provide a consistent structural support, stiffness, and strength along the reinforcement beam. 
     Referring now to the vehicle component  10  shown in  FIG. 3 , a sill panel  14  partially defines a hollow interior space  16 . The vehicle component  10  shown in  FIG. 3  is embodied as a vehicle rocker component, such as the rocker component  102  shown in  FIGS. 1 and 2 . The sill panel  14 , which may be referred to as a sill outer panel of a rocker component, has a C-shaped cross section with flanges  18 ,  20  that together provide a generally hat-shaped cross section. The flanges  18 ,  20  may be referred to as an upper flange  18  and a lower flange  20  of the sill panel  14 . The upper and lower flanges  18 ,  20  of the sill panel  14  shown in  FIG. 3  extend longitudinally, continuously along the edges of the rocker component; however, it is contemplated that the flanges may be trimmed away in select areas to facilitate frame attachment or to reduce weight. 
     The sill panel  14 , or outer panel of the rocker component  10  has an outer wall  32  that is substantially planar and integrally interconnects with an upper wall  34  and a lower wall  36  at its respective upper and lower ends. The corner transitions of approximately 100 degrees between the outer wall  32  and the upper and lower walls  34 ,  36  are defined by longitudinal bends to a sheet material that forms the second sill panel  14 . The sheet material may be the same or different from the sill panel  14  and may include a metal sheet, such as an advanced high strength steel sheet or aluminum sheet. Similarly, the upper wall  34  also has a corner transition to the upper flange  22  and the lower wall  36  has a corner transition to the lower flange  24 , which are each also defined by longitudinal bends in the sheet material of the second sill panel  14 . Again, the corner transitions between the upper and lower walls  34 ,  36  and the upper and lower flanges  22 ,  24  and the inner wall  32  may have an angular transition greater or less than shown in  FIG. 3 , such as approximately between 80 and 160 degrees, between 90 and 120 degrees, between 95 and 110 degrees, or between 97 and 105 degrees. 
     A reinforcement beam  40 , as shown for example in  FIG. 3 , is provided that includes a beam portion  42  with a multi-hollow cross-sectional shape. The beam portion  42  is disposed within the hollow interior space  16  of the rocker component  10 . By disposing the beam portion  42  at the inner volume, bulkhead members are not included or otherwise necessary to stiffen the inner portion of the rocker component. The reinforcement beam  40  also includes a flange portion  44  that integrally extends from the beam portion  42 . The flange portion  44  is configured to be joined to the first sill panel  14 . 
     As shown in  FIG. 3 , the reinforcement beam  40  is roll formed from a metal sheet to provide the beam portion  42  and the flange portion  44  as integral sections of the metal sheet. The flange portion  44  of the reinforcement beam  40  is provided at and comprises an edge  45  of the metal sheet. The flange portion  44  extends longitudinally and continuously along a length of the reinforcement beam  40 . The length of the reinforcement beam  40  is be substantially equal to a length of the hollow interior space  16 . In additional implementations, the length of the reinforcement beam may be shorter than the length of the hollow interior space of the corresponding component, such as between 40% and 100%, between 30% and 90%, or between 30% and 60% of the length of the reinforcement beam. For example, in combustion powered vehicles a reinforcement beam may have length less than 90%, or in other examples less than 60%, of the length of the rocker component to be disposed at a desired longitudinal section of a rocker component, such as a central section that may be more susceptible to impact or unsupported areas between pillars or crossmembers of the vehicle. 
     As further shown in  FIG. 3 , the beam portion  42  of the reinforcement beam  40  has a plurality of longitudinal bends in the metal sheet that each form angular transitions between and define separate wall sections of the beam portion  42 . Several wall sections are angled relative to each other to form a tubular shape that surrounds an interior area that extends longitudinally along the reinforcement beam. As shown in  FIG. 3 , the wall sections of the beam portion  42  include an upper wall section  46 , an inner wall section  48 , a lower wall section  50 , an outer wall section  52 , a lower shear wall section  54 , a mid-wall section  56 , and an upper shear wall section  58 . The upper wall section  46 , inner wall section  48 , and upper shear wall section  58 , together with a wall section  59  formed by a lower end of the flange portion  44  form a tubular shape that generally surrounds an upper interior area  60 . Also, the inner wall section  48 , lower wall section  50 , outer wall section  52 , and lower shear wall section  54  form a tubular shape that generally surrounds a lower interior area  62 . The tubular shapes surrounding the upper and lower interior areas  60 ,  62  extend longitudinally along the reinforcement beam in parallel alignment with each other and are shown as mirror images of each other across the mid-wall section  48 . However, additional examples of the reinforcement beam may have the tubular shapes unequal in size and having dissimilar shapes. 
     The beam portion  42  shown in  FIG. 3  has an opposing edge  64  of the metal sheet from the flange portion  44  attached at an intermediate portion of the sheet to enclose at least one of the tubular shape. Specifically, the opposing edge  64  is bent to curve downward from the upper wall section  46  into the upper interior area  60  to attach to the wall section  59  in a lapped manner, such as to allow for biasing the opposing edge  64  against the wall section  59  when welding the exposed crevice, such as via laser welding in line with the roll forming operation used to form the reinforcement beam  40 . The mid-wall section  56  may also be welded to the inner wall section  48 , such as via laser welding or spot welding during the roll forming operation. In other implementations, the edge may be welded in a different configurations, such as a T-joint, and the welds may be supplemented or replaced with adhesive, fasteners, or combinations thereof. 
     The reinforcement beam  40  may be roll-formed from an advanced high-strength steel with a tensile strength above 1,000 MPA, such as approximately 1,500 MPa. The metal sheet used to roll form the reinforcement beam may be approximately 1-2 mm in thickness, such as between 1.2-1.6 mm. Also, the steel sheet used for the reinforcement beam and panels of the vehicle component is galvanized, so as to have a zinc coating that protects against corrosion. In some examples, however, the steel sheet of the reinforcement beam may not be galvanized, and in other examples the steel sheets that form the vehicle component may not be galvanized. In further examples, the metal sheet that forms the reinforcement beam is an aluminum sheet. 
     Referring still to  FIG. 3 , the rocker component  10  omits an inner sill panel and instead the inner wall section  48  of the reinforcement beam  40  defines the innermost wall of the rocker component  10 . The reinforcement beam  40  shown in  FIG. 3  is joined to the outer sill panel  14  with the integral flange portion  44  of the reinforcement beam  40  welded to the upper flange  22  of the outer sill panel  14 , such as with a spot welding process or the like. To further retain the reinforcement beam to the outer sill panel  14 , the lower flange  24  of the outer sill panel  14  may joined directly or indirectly to a lower portion of the reinforcement beam  40 . As shown in  FIG. 3 , an inner bracket  13  may be provided to connect between the lower flange  24  and the reinforcement beam  14 . The inner bracket  13  may extend continuously along the length of the rocker component  10  or may be divided into separate brackets that are attached at spaced locations along the length of the reinforcement beam  40  and the outer sill panel  14 . When continuously provided, the inner bracket  13  may enclose the hollow interior space  16  of the rocker component  10  between the outer sill panel  14  and the reinforcement beam  40 . The inner bracket  13  includes a lower flange  20  that is joined to the lower flange  24  of the outer sill panel  14  and an upper section that is integrally extends from the lower flange  24  and defines a lower wall  30 . The lower wall  30  is joined to an outboard portion of the lower wall section  50  of the reinforcement beam  40  with a weld; however, it is contemplated that additional implementations of the inner bracket  13  may be joined at alternative locations on the reinforcement beam  40  (such as by extending upward without a bend transition to attach to the outer wall section  52  or the reinforcement beam  40 ) and may be joint with alternative joining features, such as fasteners, adhesive, and the like. Additionally, it is contemplated that the inner bracket  13  may comprise an upper inner bracket and a lower inner bracket, as described in more detail below. 
     With reference to the vehicle component  110  shown in  FIG. 4 , a sill panel  114  and a reinforcement beam  140  is provided that includes a beam portion  142  with a multi-hollow cross-sectional shape and a flange portion  144  that integrally extends from the beam portion  142 . The beam portion  142  is disposed within the hollow interior space  116  of the rocker component  110 , and specifically within the inner volume formed by the panel  114 . The flange portion  144  is attached, such as via spot welding, to secure the reinforcement beam  140  relative to the panel  114 . The beam portion  142  of the reinforcement beam  40  has a plurality of longitudinal bends in a metal sheet used to form the reinforcement beam  140  that each form angular transitions between and define separate wall sections of the beam portion  142 . 
     As further shown in  FIG. 4 , the upper wall section  146 , inner wall section  148 , and upper shear wall section  158 , together with a wall section  159  formed by a lower end of the flange portion  144  form a tubular shape that generally surrounds an upper interior area  160 . Also, the inner wall section  148 , lower wall section  150 , outer wall section  152 , and lower shear wall section  154  form a tubular shape that generally surrounds a lower interior area  162 . The tubular shapes surrounding the upper and lower interior areas  160 ,  162  extend longitudinally along the reinforcement beam in parallel alignment with each other and each have a generally rectangular cross-sectional shape. Thus, when secured within the hollow interior space  116  of the rocker component, the upper and lower wall sections  146 ,  150 , as well as the shear wall sections  154 ,  158  provide shear support to the inner wall  126  by being substantially perpendicular to the inner wall  126 . To also reinforce the inner wall  126 , the inner wall section  148  of the reinforcement beam  140  interfaces in contact with and may be attached at (e.g., via welding) a generally parallel inner surface of the inner wall  126 . Other features of the reinforcement beam  140  that are similar to the reinforcement beam  40  are not described in detail again, and similar reference numbers are used, incremented by  100 . 
     As shown in  FIG. 4 , the rocker component  110  omits an inner sill panel and instead the inner wall section  148  of the reinforcement beam  140  defines the innermost wall of the rocker component  110 . The reinforcement beam  40  shown in  FIG. 4  is joined to the outer sill panel  114  with the integral flange portion  144  of the reinforcement beam  40  welded to the upper flange  122  of the outer sill panel  114 , such as with a spot welding process or the like. To further retain the reinforcement beam to the outer sill panel  114 , the lower flange  124  of the outer sill panel  114  may joined directly or indirectly to a lower portion of the reinforcement beam  140 . As shown in  FIG. 4 , an inner bracket  113  may be provided to connect between the lower flange  124  and the reinforcement beam  114 . The inner bracket  113  may extend continuously along the length of the rocker component  110  or may be divided into separate brackets that are attached at spaced locations along the length of the reinforcement beam  40  and the outer sill panel  114 . When continuously provided, the inner bracket  113  may enclose the hollow interior space  116  of the rocker component  110  between the outer sill panel  114  and the reinforcement beam  140 . The inner bracket  113  includes a lower flange  120  that is joined to the lower flange  124  of the outer sill panel  114  and an upper section that is integrally extends from the lower flange  124  and defines a lower wall  130 . The lower wall  130  is joined to an outboard portion of the lower wall section  150  of the reinforcement beam  140  with a weld; however, it is contemplated that additional implementations of the inner bracket  113  may be joined at alternative locations on the reinforcement beam  140  (such as by extending upward without a bend transition to attach to the outer wall section  152  or the reinforcement beam  140 ) and may be joint with alternative joining features, such as fasteners, adhesive, and the like. 
     Referring now to the vehicle component  210  shown in  FIG. 5 , a reinforcement beam  240  is provided that includes a beam portion  242  with a multi-hollow cross-sectional shape and a flange portion  244  that integrally extends from the beam portion  242 . The multi-hollow cross-sectional shape of the beam portion  242  has two hollow interior areas  260 ,  262  that are divided by a single, common center wall section, shown as a center shear wall section  254 . The reinforcement beam  240  may be roll formed from a metal sheet, so as to form a plurality of longitudinal bends in the metal sheet used that each form angular transition between separate wall sections of the beam portion  242 . 
     As further shown in  FIG. 5 , the upper wall section  246 , an upper inner wall section  248   a,  the center shear wall section  254 , and an upper outer wall section  257  form a tubular shape that generally surrounds an upper interior area  260 . Also, a lower inner wall section  248   b,  lower wall section  250 , a lower outer wall section  252 , and the center shear wall section  254  form a tubular shape that generally surrounds a lower interior area  262 . The lower outer wall section  252  is provided in planar alignment with the flange portion  244  and is disposed at a lower end thereof. Also, the wall section  259  immediate above the lower outer wall section  252  is a planar extension of the flange portion  244  and overlaps the upper outer wall section  257  to provide a double wall thickness. 
     The beam portion  242  shown in  FIG. 5  has an opposing edge  264  of the metal sheet from the flange portion  244  attached at an intermediate portion of the sheet to enclose the tubular shape around the upper interior area  260 . Specifically, the opposing edge  264  is curved inward from the upper inner wall section  248   a  into the upper interior area  260  to attach to the center wall section  254  in a lapped manner to weld the exposed crevice, such as via laser welding. The wall section  259  may also be welded to the upper inner wall section  257 , such as via laser welding. In other implementations, the edge may be welded in a different configurations, such as lap to the lower outer wall section or a T-joint with the corner transition between the center wall section and the lower outer wall section. 
     The tubular shapes surrounding the upper and lower interior areas  260 ,  262  extend longitudinally along the reinforcement beam in parallel alignment with each other and each have a generally rectangular cross-sectional shape. Thus, when secured within the hollow interior space  216  of the rocker component, the upper and lower wall sections  246 ,  250 , as well as the center shear wall section  254  provide shear support to the inner wall  226  by being substantially perpendicular to the inner wall  226 . To also reinforce the inner wall  226 , the upper and lower inner wall sections  248   a,    248   b  of the reinforcement beam  240  interfaces in contact with and may attach at a generally parallel inner surface of the inner wall  226 . Other features of the reinforcement beam  240  that are similar to the reinforcement beam  40  are not described in detail again, and similar reference numbers are used, incremented by  200 . 
     As further shown in  FIG. 5 , the rocker component  210  omits an inner sill panel and instead the inner wall section  248  of the reinforcement beam  240  defines the innermost wall of the rocker component  210 . The reinforcement beam  240  shown in  FIG. 5  is joined to the outer sill panel  214  with the integral flange portion  244  of the reinforcement beam  240  welded to the upper flange  222  of the outer sill panel  214 , such as with a spot welding process or the like. To further retain the reinforcement beam to the outer sill panel  214 , the lower flange  224  of the outer sill panel  214  may joined directly or indirectly to a lower portion of the reinforcement beam  240 . As shown in  FIG. 5 , an inner bracket  213  may be provided to connect between the lower flange  224  and the reinforcement beam  214 . The inner bracket  213  may extend continuously along the length of the rocker component  210  or may be divided into separate brackets that are attached at spaced locations along the length of the reinforcement beam  240  and the outer sill panel  214 . When continuously provided, the inner bracket  213  may enclose the hollow interior space  216  of the rocker component  210  between the outer sill panel  214  and the reinforcement beam  240 . The inner bracket  213  includes a lower flange  220  that is joined to the lower flange  224  of the outer sill panel  214  and an upper section that is integrally extends from the lower flange  224  and defines a lower wall  230 . The lower wall  230  is joined to an outboard portion of the lower wall section  250  of the reinforcement beam  240  with a weld; however, it is contemplated that additional implementations of the inner bracket  213  may be joined at alternative locations on the reinforcement beam  240  (such as by extending upward without a bend transition to attach to the outer wall section  252  or the reinforcement beam  240 ) and may be joint with alternative joining features, such as fasteners, adhesive, and the like. 
     Referring now to  FIG. 6 , a rocker component  310  is shown that has a reinforcement beam  340  that is roll formed from a metal sheet to provide a beam portion  342  that includes a multi-hollow cross-sectional shape with four enclosed interior areas  360 ,  361 ,  362 ,  363  and five wall sections  346 ,  354 ,  350  that provide shear support and divide the enclosed interior areas. The flange portion  344  integrally extends from the beam portion  342  and is provided by an edge of the metal sheet used to form the beam portion  342 . As shown in  FIG. 6 , the flange portion  344  extends linearly downward along an outer side of the beam portion  342  to a lower wall section  350 , defining an upper outer wall section  359  and a lower outer wall section  352 . From the inner end of the lower wall section  350 , the metal sheet transitions upward in a serpentine curved formation to provide three intermediate shear wall sections  354  before transitioning outward at the upper wall section  346  before transitioning linearly downward along an inner side of the beam portion  342 . The inner side of the beam portion  342  defines upper and lower inner wall section  348   a,    348   b.    
     As illustrated in  FIG. 6 , the beam portion  342  includes an upper wall section  346 , an upper inner wall section  348   a,  a central shear wall section  354 , and an upper outer wall section  357  that together form a tubular shape that generally surrounds an upper interior area  360 . Adjacent to and below the upper interior area  360 , an intermediate interior area  361  is bordered by the same central shear wall section  354 , a mid-wall section  356 , another central shear wall section  354 , and an upper outer wall section  359 . Adjacent to and below the intermediate interior area  361 , another intermediate interior area  362  is bordered by the same central shear wall section  354  that borders the intermediate interior area  361 , a lower inner wall section  348   b,  another central shear wall section  354 , and a lower outer wall section  357 . Finally, adjacent to and below the intermediate interior area  362 , a lower interior area  363  is bordered by the same central shear wall section  354  that borders the intermediate interior area  362 , a lower mid-wall section  356 , a lower wall section  350 , and a lower outer wall section  352 . 
     As also shown in  FIG. 6 , the wall sections of the beam portion  342  provide shear support by wall sections that are substantially perpendicular to the inner wall  326 , which is parallel to a planar extension of the flange portion  344  of the reinforcement beam  340 . The shear support shown in  FIG. 6  is provided by the lower wall section  350 , as well as the shear wall sections  354  and the upper wall section  345  that are each angled approximately 30 degrees relative to the flange portion  344 . In additional implementations, the serpentine shape may provide differently shaped wall sections, such as shear wall sections that are angled 0 to 60 degrees, or 0 to 45 degrees, or 0 to 30 degrees from a perpendicular extension from the inner wall  326  of the vehicle component  310 . Other features of vehicle component  310  and associated reinforcement beam  340  that are similar to the vehicle component  10  and reinforcement beam  40  are not described in detail again, and similar reference numbers are used, incremented by  300 . 
     Additionally as shown in  FIG. 6 , the inner sill panel is omitted and instead the inner wall section  348  of the reinforcement beam  340  defines the innermost wall of the rocker component  310 . For sake of avoiding repetition, other features of the rocker component  310  shown in  FIG. 6  that are the same or similar to the rocker component  310  of  FIG. 6 , including those with like reference numbers, are not described again in detail. The reinforcement beam  340  shown in  FIG. 6  is joined to the outer sill panel  314  with the integral flange portion  344  of the reinforcement beam  340  welded to the upper flange  322  of the outer sill panel  314 , such as with a spot welding process or the like. To further retain the reinforcement beam to the outer sill panel  314 , the lower flange  324  of the outer sill panel  314  may joined directly or indirectly to a lower portion of the reinforcement beam  340 . As shown in  FIG. 6 , an inner bracket  313  may be provided to connect between the lower flange  324  and the reinforcement beam  314 . The inner bracket  313  may extend continuously along the length of the rocker component  310  or may be divided into separate brackets that are attached at spaced locations along the length of the reinforcement beam  340  and the outer sill panel  314 . When continuously provided, the inner bracket  313  may enclose the hollow interior space  316  of the rocker component  310  between the outer sill panel  314  and the reinforcement beam  340 . The inner bracket  313  includes a lower flange  320  that is joined to the lower flange  324  of the outer sill panel  314  and an upper section that is integrally extends from the lower flange  324  and defines a lower wall  330 . The lower wall  330  is joined to an outboard portion of the lower wall section  350  of the reinforcement beam  340  with a weld; however, it is contemplated that additional implementations of the inner bracket  313  may be joined at alternative locations on the reinforcement beam  340  (such as by extending upward without a bend transition to attach to the outer wall section  352  or the reinforcement beam  340 ) and may be joint with alternative joining features, such as fasteners, adhesive, and the like. 
     Referring now to  FIGS. 7A-16 , the reinforcement beam may include a second flange portion, such as a flange portion  466 ,  566  ( FIGS. 7A and 8A ) formed by an opposing edge portion of the metal sheet. The second flange portion may be attached, such as with spot welding, to the sill panel. In doing so, the reinforcement beam may eliminate the use of one or both sill panels that can extend between the flanges so as to integrate some or all of the structural features of the individual sill panels. Also in providing the second flange portion as an integral extension from the beam portion of the reinforcement beam, in some examples, the beam portion of the reinforcement beam may be spaced or separated from the inner surfaces of the inner and outer panels of the vehicle component, such as to provide two points of connection between the reinforcement beam and the panel and additional hollow areas or lateral crush zones. 
     As shown in  FIG. 7A , a reinforcement beam  440  is provided that includes a beam portion  442  with a multi-hollow cross-sectional shape and two flange portions  444 ,  466  that integrally extends from the beam portion  442 . The multi-hollow cross-sectional shape of the beam portion  442  has three hollow interior areas  460 ,  461 ,  462  that are divided by central wall sections  454 ,  464 . The reinforcement beam  440  is roll formed from a metal sheet, so as to form a plurality of longitudinal bends in the metal sheet used that each form angular transition between separate wall sections of the beam portion  442 . 
     The cross-sectional shape of the beam portion  442 , as shown in  FIG. 7A , provides the upper flange portion  444  extending linearly downward along an outer side of the beam portion  442  to a lower wall section  450 , defining an outer wall section  452  of the reinforcement beam  440 . From the inner end of the lower wall section  450 , the metal sheet transitions upward in a diagonal formation to provide two intermediate shear wall sections  454  before transitioning inward at the upper wall section  446  and then transitioning linearly downward along an inner side of the beam portion  442  to defines upper and lower outer wall section  448   a,    448   b.  The upper wall section  446 , the upper inner wall section  448   a,  a central shear wall section  454 , and an upper outer wall section  457  together form a tubular shape that generally surrounds an upper interior area  460 . Adjacent to and below the upper interior area  460 , an intermediate interior area  461  is bordered by the same central shear wall section  454 , a mid-wall section  456 , another central shear wall section  454 , and the outer wall section  452 . Adjacent to and below the intermediate interior area  461 , a lower interior area  462  is bordered by the same central shear wall section  454  that borders the intermediate interior area  461 , a lower inner wall section  448   b,  and a lower wall section  450 . The wall sections of the beam portion  442  provide shear support with wall sections that are substantially perpendicular to the inner wall  426 , such as the lower wall section  450 , upper wall section  446 , as well as the shear wall sections  454  that are angled approximately 45 degrees relative to the flange portion  444 . Other features of the vehicle component  410  and associated reinforcement beam  440  that are similar to the vehicle component  10  and reinforcement beam  40  are not described in detail again, and similar reference numbers are used, incremented by  400 . 
     As shown in  FIG. 7A , the rocker component  410  has the inner sill panel omitted and instead the inner wall section  448  of the reinforcement beam  440  defines the innermost wall of the rocker component  410 . Thus, the reinforcement beam  440  integrates a sill panel with a reinforcement structure utilizing a single metal sheet. The reinforcement beam  440  shown in  FIG. 7A  is joined to the outer sill panel  414  with the integral upper and lower flange portions  444 ,  466  welded to the respective upper and lower flanges  422 ,  424  of the outer sill panel  414 , such as with spot welding or laser welding or the like. 
     As shown in  FIG. 7B , additional implementations of the rocker component  410  have the outer sill panel omitted. In this example, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  410 . Thus, the reinforcement beam  440  may integrate a sill panel with a reinforcement structure by utilizing a single metal sheet. Other features of the vehicle component  410  and associated reinforcement beam  440  that are similar to the vehicle components  10 ,  410  and reinforcement beams  40 ,  440  are not described in detail again, and like reference numbers are used, incremented by  400 . 
     As shown in  FIG. 8A , a reinforcement beam  540  is provided with a similar configuration to the reinforcement beam  440  shown in  FIG. 7A  with a beam portion  542  that has three hollow interior areas  560 ,  561 ,  562  that are divided by central wall sections  554 ,  564 . Different from the reinforcement beam  440 , the central wall section  554  is oriented perpendicular relative to the inner wall  526  and the upper and lower inner wall section  548   a,    548   b.  Accordingly, the upper outer wall section  557  and the mid-wall section  556  extend along a greater extent of the respective outer wall section  552  and inner wall section  548   a,    548   b.    
     Also, as shown in  FIG. 8A , the rocker component  510  has the inner sill panel omitted and instead the inner wall section  548  of the reinforcement beam  540  defines the innermost wall of the rocker component  510 . Thus, the reinforcement beam  440  integrates a sill panel with a reinforcement structure utilizing a single metal sheet. The reinforcement beam  540  shown in  FIG. 8A  is joined to the outer sill panel  514  with the integral upper and lower flange portions  544 ,  566  welded to the respective upper and lower flanges  522 ,  524  of the outer sill panel  514 , such as with spot welding or laser welding or the like. Other features of the vehicle component  510  and associated reinforcement beam  540  that are similar to the vehicle components  10 ,  410  and reinforcement beams  40 ,  440  are not described in detail again, and similar reference numbers are used, incremented by  500 . 
     As shown in  FIG. 8B , additional implementations of the rocker component  510  have the outer sill panel omitted. In this example, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  510 . Thus, the reinforcement beam  540  may integrate a sill panel with a reinforcement structure by utilizing a single metal sheet. Other features of the vehicle component  510  and associated reinforcement beam  540  that are similar to the vehicle components  10 ,  510  and reinforcement beams  40 ,  540  are not described in detail again, and like reference numbers are used, incremented by  500 . 
     Referring to  FIGS. 9A-16 , the reinforcement beam may have a cross-sectional shape that is expanded laterally outward. In doing so, the outer portion of the rocker component may be stiffened, such as for decreasing impact intrusion resistance as may be desirable for electric vehicles having battery modules disposed between the rocker assemblies. As shown in  FIGS. 9A-12D , the beam portion of the reinforcement beam includes two hollow interior areas that are divided by a common center wall section  654 ,  754 ,  854 ,  954  that is oriented substantially vertically in alignment with the upper and lower flanges and flange portions of the corresponding reinforcement beam. The vertical center wall sections  654 ,  754 ,  854 ,  954  are provided by a cross-sectional shape similar to the reinforcement beam  240  shown in  FIG. 5  and rotated approximately 90 degrees about a longitudinal axis of the reinforcement beam to vertically orient the shear wall section  254 . 
     With respect to the reinforcement beam  640  shown in  FIG. 9A , the outer lower wall section  651  is disposed below and extending outward to overlap a portion of the inner lower wall section  650 . The center wall section  654  extends upward beyond the inner upper wall section  646  to partially overlap a lower end of the flange portion  644 , such that the outer upper wall section  645  that integrally extends from the upper end of the center wall section  654  is disposed vertically above the inner upper wall section  646 . Other features of the vehicle component  610  and associated reinforcement beam  640  that are similar to the vehicle components  10 ,  410  and reinforcement beams  40 ,  440  are not described in detail again, and similar reference numbers are used, incremented by  600 . 
     As shown in  FIGS. 9A, 9B, 9C, and 9D , some implementations of the rocker component  610  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  610 . Thus, the reinforcement beam  640  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 9A , the rocker component includes brackets  628 ,  630 ,  634 , and  636  to help support the reinforcement beam  640 . The brackets  628 ,  630 ,  634 , and  636  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  645 ,  646 ,  650 ,  651 . More specifically,  FIG. 9A  includes four brackets  628 ,  630 ,  634 ,  636 , two upper and two lower which are configured to sandwich both upper and lower flange portions  644 ,  666  of the reinforcement beam. In the example shown in  FIG. 9B , the brackets  628 ,  630  disposed adjacent to the inner portion of the reinforcement beam  640  are omitted while the brackets  634 ,  636  disposed adjacent to the outer portion of the reinforcement beam  640  are present. In the example shown in  FIG. 9C , the brackets  634 ,  636  disposed adjacent to the outer portion of the reinforcement beam  640  are omitted while the brackets  628 ,  630  disposed adjacent the inner portion of the reinforcement beam  640  are present. In the example shown in  FIG. 9D , all of the brackets  628 ,  630 ,  634 ,  636  are omitted. For sake of avoiding repetition, other features of the rocker component  610  shown in  FIGS. 9A-9D  that are the same or similar to the rocker component  610  of  FIG. 9A , including those with like reference numbers, are not described again in detail. 
     As shown in  FIG. 10A , a reinforcement beam  740  is provided with a similar configuration to the reinforcement beam  640  shown in  FIG. 9A  with a beam portion  742  that has two hollow interior areas  760 ,  762  that are divided by a central wall section  754 . Different from the reinforcement beam  640 , the outer lower wall section  751  is disposed above and does not overlap a portion of the inner lower wall section  750 . Accordingly, the center wall section  754  extends downward beyond the outer lower wall section  751  to partially overlap an upper end of the second flange portion  766 , such that the inner lower wall section  750  that integrally extends from the lower end of the center wall section  754  is disposed vertically below the outer lower wall section  751 . 
     As shown in  FIGS. 10A, 10B, 10C, and 10D , some implementations of the rocker component  710  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  710 . Thus, the reinforcement beam  740  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 10A , the rocker component includes brackets  728 ,  730 ,  734 , and  736  to help support the reinforcement beam  740 . The brackets  728 ,  730 ,  734 , and  736  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  745 ,  746 ,  750 ,  751 . More specifically,  FIG. 10A  includes four brackets  728 ,  730 ,  734 ,  736 , two upper and two lower which are configured to sandwich both upper and lower flange portions  744 ,  766  of the reinforcement beam. In the example shown in  FIG. 10B , the brackets  728 ,  730  disposed adjacent to the inner portion of the reinforcement beam  740  are omitted while the brackets  734 ,  736  disposed adjacent to the outer portion of the reinforcement beam  740  are present. In the example shown in  FIG. 10C , the brackets  734 ,  736  disposed adjacent to the outer portion of the reinforcement beam  740  are omitted while the brackets  728 ,  730  disposed adjacent the inner portion of the reinforcement beam  740  are present. In the example shown in  FIG. 10D , all of the brackets  728 ,  730 ,  734 ,  736  are omitted. For sake of avoiding repetition, other features of the rocker component  710  shown in  FIGS. 10A-10D  that are the same or similar to the rocker component  710  of  FIG. 10A , including those with like reference numbers, are not described again in detail. 
     As shown in  FIGS. 11A-11D and 12A-12D , reinforcement beams  840 ,  940  are also provided with a similar configuration to the reinforcement beam  640  shown in  FIGS. 9A-9D  with beam portions  842 ,  942  that each have two hollow interior areas  860 ,  862 ,  960 ,  962  that are respectively divided by a central wall section  854 ,  954 . Different from the reinforcement beam  640 , the outer upper wall section  845 ,  945  is disposed above and overlaps a portion of the inner upper wall section  846 ,  946 . Accordingly, the center wall section  854 ,  954  does not overlap either flange portion  844 ,  866 ,  944 ,  966 , such that the center wall section  854 ,  954  terminates at the intermediate extent of the outer upper wall section  845 ,  945  at the upper end and at the intermediate extent of the inner lower wall section  850 ,  950 . The center wall section  854 ,  954  may then be generally centered between the laterally offset flanges, such as when laterally offset at a larger distance as shown in  FIGS. 11A-11D  when compared to the relatively shorter lateral offset shown in  12 A- 12 D. 
     As shown in  FIGS. 11A, 11B, 11C, and 11D , some implementations of the rocker component  810  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  810 . Thus, the reinforcement beam  840  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 11A , the rocker component includes brackets  828 ,  830 ,  834 , and  836  to help support the reinforcement beam  840 . The brackets  828 ,  830 ,  834 , and  836  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  845 ,  846 ,  850 ,  851 . More specifically,  FIG. 11A  includes four brackets  828 ,  830 ,  834 ,  836 , two upper and two lower which are configured to sandwich both upper and lower flange portions  844 ,  866  of the reinforcement beam. In the example shown in  FIG. 11B , the brackets  828 ,  830  disposed adjacent to the inner portion of the reinforcement beam  840  are omitted while the brackets  834 ,  836  disposed adjacent to the outer portion of the reinforcement beam  840  are present. In the example shown in  FIG. 11C , the brackets  834 ,  836  disposed adjacent to the outer portion of the reinforcement beam  840  are omitted while the brackets  828 ,  830  disposed adjacent the inner portion of the reinforcement beam  840  are present. In the example shown in  FIG. 11D , all of the brackets  828 ,  830 ,  834 ,  836  are omitted. For sake of avoiding repetition, features of the rocker component  910  shown in  FIGS. 12A-12D  that are the same or similar to the rocker component  810  of  FIGS. 11A-11D , including those with like reference numbers, are not described again in detail and are illustrated in the drawings with similar reference numbers, incremented by  900 . 
     As shown in  FIGS. 13A-13D , the upper and lower flanges  1018 ,  1020 ,  1022 ,  1024  may be vertically aligned. The reinforcement beam  1040  shown in  FIGS. 13A-13D  is a similar configuration to the reinforcement beam  840  shown in  FIGS. 11A-11D  with portions of the upper wall sections  1045 ,  1046  overlapping and with portions of the lower wall sections  1050 ,  1051  overlapping. The central wall sections  1054 , however, are provided similar to the reinforcement beam  340  shown in  FIG. 6  with the metal sheet transitioning upward in an alternating diagonal formation to provide three intermediate shear wall sections  1054  before transitioning inward at the upper wall section  1046  and then transitioning linearly downward along an inner side of the beam portion  1042  to defines upper and lower inner wall sections  1048   a,    1048   b.    
     As shown in  FIGS. 13A, 13B, 13C, and 13D , some implementations of the rocker component  1010  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  1010 . Thus, the reinforcement beam  1040  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 13A , the rocker component includes brackets  1028 ,  1030 ,  1034 , and  1036  to help support the reinforcement beam  1040 . The brackets  1028 ,  1030 ,  1034 , and  1036  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  1045 ,  1046 ,  1050 ,  1051 . More specifically,  FIG. 13A  includes four brackets  1028 ,  1030 ,  1034 ,  1036 , two upper and two lower which are configured to sandwich both upper and lower flange portions  1044 ,  1066  of the reinforcement beam. In the example shown in  FIG. 13B , the brackets  1028 ,  1030  disposed adjacent to the inner portion of the reinforcement beam  1040  are omitted while the brackets  1034 ,  1036  disposed adjacent to the outer portion of the reinforcement beam  1040  are present. In the example shown in  FIG. 13C , the brackets  1034 ,  1036  disposed adjacent to the outer portion of the reinforcement beam  1040  are omitted while the brackets  1028 ,  1030  disposed adjacent the inner portion of the reinforcement beam  1040  are present. In the example shown in  FIG. 13D , all of the brackets  1028 ,  1030 ,  1034 ,  1036  are omitted. For sake of avoiding repetition, other features of the rocker component  1010  shown in  FIGS. 13B-D  that are the same or similar to the rocker component  1010  of  FIG. 13A , including those with like reference numbers, are not described again in detail. In additional implementations, the angular orientation of the central wall section is arranged to generally extend between offset flanges, such to angle from the upper flanges toward lower flanges that are offset inward from the upper flanges. 
     Referring to  FIGS. 14A-14D , additional examples of a rocker component  1110  is shown having a similar configuration to the examples shown in  FIGS. 9A-9D  with the cross-sectional shape of the reinforcement beam  1140  altered primarily at the degree of angle transitions between wall sections of the beam portion  1142  and between the beam portion  1142  and the flange portions  1144 ,  1166 . For example, the beam portion  1142  of the reinforcement beam  1140  includes a substantially horizontal wall section  1153  along a portion of the central wall section  1154  to provide a shear wall section in addition to the upper and lower shear wall sections  1145 ,  1146 ,  1150 . 
     As shown in  FIGS. 14A, 14B, 14C, and 14D , some implementations of the rocker component  1110  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  1110 . Thus, the reinforcement beam  1140  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 14A , the rocker component includes brackets  1128 ,  1130 ,  1134 , and  1136  to help support the reinforcement beam  1140 . The brackets  1128 ,  1130 ,  1134 , and  1136  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  1145 ,  1146 ,  1150 ,  1151 . More specifically,  FIG. 14A  includes four brackets  1128 ,  1130 ,  1134 ,  1136 , two upper and two lower which are configured to sandwich both upper and lower flange portions  1144 ,  1166  of the reinforcement beam. In the example shown in  FIG. 14B , the brackets  1128 ,  1130  disposed adjacent to the inner portion of the reinforcement beam  1140  are omitted while the brackets  1134 ,  1136  disposed adjacent to the outer portion of the reinforcement beam  1140  are present. In the example shown in  FIG. 14C , the brackets  1134 ,  1136  disposed adjacent to the outer portion of the reinforcement beam  1140  are omitted while the brackets  1128 ,  1130  disposed adjacent the inner portion of the reinforcement beam  1140  are present. In the example shown in  FIG. 14D , all of the brackets  1128 ,  1130 ,  1134 ,  1136  are omitted. For sake of avoiding repetition, other features of the rocker component  1110  shown in  FIGS. 14B-9D  that are the same or similar to the rocker component  1110  of  FIG. 14A , including those with like reference numbers, are not described again in detail. 
     Further examples of a rocker component  1210  are shown in  FIGS. 15A-15D , having a similar configuration to the examples shown in  FIGS. 7A-7D  with the cross-sectional shape of the reinforcement beam  1240  altered in the roll form bending configuration or flower pattern of the metal sheet that forms the reinforcement beam  1240 . Specifically, the reinforcement beam  1240  forms an upper tubular portion surrounding an upper hollow area  1260  and a lower tubular portion surrounding a lower hollow area  1262 , with the sheet connecting the upper and lower tubular portions along an outer wall section  1232  of the reinforcement beam  1240  to enclose a third hollow area  1261 . 
     As shown in  FIGS. 15A, 15B, 15C, and 15D , some implementations of the rocker component  1210  have both the inner sill panel omitted and the outer sill panel omitted. In these examples, the wall section of the reinforcement beam adjacent to the omitted sill panel defines the corresponding innermost or outermost wall of the rocker component  1210 . Thus, the reinforcement beam  1240  may integrate one or two sill panels with a reinforcement structure by utilizing a single metal sheet. Additionally, in the example shown in  FIG. 15A , the rocker component includes brackets  1228 ,  1230 ,  1234 , and  1236  to help support the reinforcement beam  1240 . The brackets  1228 ,  1230 ,  1234 , and  1236  are generally L-shaped brackets which have a generally vertically extending portion similar to the flange portion of a sill inner and a laterally extending portion which extends to the corresponding shear wall of the reinforcement beam  1245 ,  1246 ,  1250 ,  1251 . More specifically,  FIG. 15A  includes four brackets  1228 ,  1230 ,  1234 ,  1236 , two upper and two lower which are configured to sandwich both upper and lower flange portions  1244 ,  1266  of the reinforcement beam. In the example shown in  FIG. 15B , the brackets  1228 ,  1230  disposed adjacent to the inner portion of the reinforcement beam  1240  are omitted while the brackets  1234 ,  1236  disposed adjacent to the outer portion of the reinforcement beam  1240  are present. In the example shown in  FIG. 15C , the brackets  1234 ,  1236  disposed adjacent to the outer portion of the reinforcement beam  1240  are omitted while the brackets  1228 ,  1230  disposed adjacent the inner portion of the reinforcement beam  1240  are present. In the example shown in  FIG. 15D , all of the brackets  1228 ,  1230 ,  1234 ,  1236  are omitted. For sake of avoiding repetition, other features of the rocker component  1210  shown in  FIGS. 15A-15D  that are the same or similar to the rocker component  1210  of  FIG. 15A , including those with like reference numbers, are not described again in detail. 
     Similar to the reinforcement beam  1240  and rocker component of  FIG. 15A-D , another example of a rocker component  1310  is shown in  FIG. 16  with like reference numbers incremented by  100  from that shown in  FIGS. 15A-15D . As shown in  FIG. 16  (as also shown in  FIG. 1A ), the rocker component  1310  is situated outboard to a battery tray and inboard to a body side panel. Also, a floor crossmember is shown spanning above the battery tray and interconnecting with the inner portion of the rocker component  1310 , above the upper hollow area  160  and inboard the upper flange  1344 . Additional connection configurations are also contemplated for other examples, such as the example shown in  FIG. 1B . 
     Although the reinforcement beam may have a structure at the beam portion that provides sufficient stiffness and strength, it is contemplated that the vehicle component may include one or more bulkhead members that are disposed generally orthogonally relative to the longitudinal extent of the rocker component. For example, when the outer rocker panel is desired to be further stiffened, such as for protecting battery modules disposed in a tray between rocker assembles, a series of bulkhead members may be disposed at spaced intervals along the hollow interior between an outer wall section of the reinforcement beam and an outer panel of a rocker component. The bulkhead members may connect to the outer panel and/or reinforcement beam with a mechanical fastener, welding, adhesive, or any combination thereof. Moreover, it is contemplated that the inner and outer panels may include wall stiffeners that may be attached at select locations of the inner and outer panels. For example, the wall stiffeners may be attached at and reinforce the rounded corners of the metal sheets that form the inner and outer panels. It is contemplated that additional or alternative attachment locations may be used in other examples. 
     It is also contemplated that the internal reinforcements of the disclosed vehicle component may be incorporated in other types of structural beams, such as in frames and structures of automotive and marine vehicles, buildings, storage tanks, furniture, and the like. With respect to vehicle applications, the vehicle component disclosed herein may be incorporated with various applications of different structural components. The vehicle component may be designed to support and sustain different loading conditions, such as for supporting certain horizontal spans or axial loading conditions. Also, the vehicle component may be designed to undergo various impact forces, such as for the illustrated rocker assemblies, pillar structures, and the like. The cross-sectional geometry, material type selections, and material thickness within the cross-sectional profile of the vehicle component may be configured for such a particular use and the desired loading and performance characteristics, such as the weight, load capacity the beam, force deflection performance, and impact performance of the vehicle component.
