SECTION 05410

LOAD BEARING METAL STUD SYSTEM

[PART 1: GENERAL]{.underline}

1.1 SUMMARY

A. Section Includes: Providing and installing steel studs and related
framing in partitions and curtain walls as shown on the drawings and as
herein specified.

1.2 SUBMITTALS

A. General: Submittals shall be according to \[Section 01009 - General
Information and Requirements.\] \[and\] \[Section 01330 - Submittal
Procedures.\] \[and\] \[Section 01331 - Certificates.\]

B. Manufacturer\'s Literature: Submit \[\_\_\] copies of the
manufacturer\'s descriptive data for materials, sizes, thicknesses, and
fastening procedure, including welding method and electrodes and types
of screws and spacing for the studs and runners to be used on this
project.

C. Shop Drawings: Submit \[\_\_\] copies of shop drawings indicating
materials, sizes, thicknesses, and fastening procedure including welding
method and electrodes and type of screws and spacing to be used on this
project.

D. Certificates of Conformance: Submit \[\_\_\] copies of written
certification from the supplier of the Contractor-furnished studs and
runners to be used on this project that they conform to the requirements
of this specification section.

1.3 QUALITY ASSURANCE

A. Labeling Requirements: Each metal element shall be identified legibly
by the manufacturer.

1.4 DELIVERY, STORAGE, AND HANDLING

A. Delivery: Studs shall be carefully loaded and unloaded from transport
vehicles to preserve structural integrity. Contractor shall inspect
steel on delivery to ascertain freedom from damage during transport and
unloading procedures. Damaged materials will be rejected and shall be
replaced by the Contractor at his expense.

B. Storage: Store in adequately ventilated dry locations. Storage area
shall permit easy access for inspection and handling. If it is necessary
to store materials outside, they shall be stacked off the ground,
properly supported on a level platform and fully protected from the
weather.

1.5 SEQUENCING AND SCHEDULING

A. Installation: Ascertain that project floor and roof framing systems
are ready for completion in areas to receive load bearing studs.

PART 2: PRODUCTS

2.1 MATERIALS

A. General: Form framing of light gauge steel. Include top and bottom
tracks, bracing, shoes, fastenings and other accessories necessary for a
complete installation. Framing shall provide the structural properties
indicated. Design of framing members shall be according to AISI
Cold-formed Steel Design Manual.

B. Load Bearing Interior Partitions: Form studs having a nominal
thickness of 0.0598 inch (16 gauge) or more of zinc-coated steel
according to ASTM A 446, Grade D, coating weight G60. Studs having a
nominal thickness of less than 0.0598 inch (16 gauge). Runners and
diagonal bracing shall be formed of zinc-coated steel according to ASTM
A 446, Grade A, coating weight G60.

C. Load Bearing Exterior Walls: Steel studs shall be 6 x 1-5/8 inch
light framing zinc-coated studs of not less than 20 gauge with a section
modulus of at least 0.580 inches cubed. Furnish compatible associated
accessories. Track channels, bridging, and similar framing members shall
be 16 gauge. Steel material shall be according to ASTM A 446, Grade B,
coating weight G60. Minimum yield strength 37 ksi.

D. Fasteners: Materials required for installation shall be as
recommended by the manufacturer of the steel materials furnished, or as
approved. Fasteners used to attach curtain wall and partition framing to
concrete floors and steel floor deck shall not penetrate more than 1-1/2
inch and shall be approved. Fasteners used on steel roof deck shall be
self-drilling and tapping with an integral gasket under the head.
Maximum length shall be 1/2 inch unless approved otherwise.

[PART 3: EXECUTION]{.underline}

3.1 INSTALLATION

A. Fastening: Fasten similar material framing members together by
welding. Fasten dissimilar materials together by the use of
self-drilling or self-tapping screws. Welding shall be according to AWS
D 1.3. Welding procedure and electrodes shall be as recommended by the
manufacturer of the framing materials. Screw connections shall be as
recommended by the manufacturer of the framing materials. Wire typing of
framing components in structural applications will not be permitted.

B. Runners: Provide runners at top and bottom accurately aligned to
ensure that partitions will be straight and plumb. Anchor runners to
floor and ceiling as indicated. Butt weld joints in runners or splice
with channel inserts securely anchored to a common structural element.

C. Studs: Position studs vertically in runners and space as indicated.
Install studs full length between runners without splices. Provide
doubled studs at jambs of doors and other openings 2 feet wide or
larger. Provide jack studs over openings, as necessary, to maintain
indicated stud spacing. Provide tripled studs at corners, positioned to
receive interior and exterior finishes. Fasten studs to top and bottom
runners by welding both flanges to runners.

D. Bridging: Use bridging sections of runner channel welded to and cut
to fit between studs or use hot or cold rolled steel channels inserted
through cutouts in web of each stud and secured to studs with welded
clip angles. Provide the following minimum bridging:

[Partition Height Bridging]{.underline}

Up to 10 feet Two rows at approximately 1/3 span

15 to 20 feet Three rows at approximately 1/4 span

20 to 25 feet Four rows at approximately 1/4 span

E. Exterior Curtain Walls: Track channels shall be attached (both at top
and bottom of wall) to structural elements with fasteners capable of
resisting at least 300 lbs per linear foot at both top and bottom with a
ratio of working load to ultimate capacity of four. Spacing of fasteners
shall not exceed 24 inches oc.

F. Framing Components: May be prefabricated into panels prior to
erection. Prefabricated panels shall be square with components attached
by welding to prevent racking. Handling and lifting of panels shall be
done in a manner as not to cause distortion in any member.

G. Structure Vertical Movement: Provisions shall be made where indicated
on the drawings, using vertical slide slip or other means according to
details.

H. Field Cutting: Small quantities, a 3 hp worm drive circular saw
equipped with a reinforced abrasive cut-off blade, a band saw or a power
hacksaw.
