Dimensions Standard products are detailed in the preceding pages. Armtec can design and fabricate grating with deeper and thicker bar sizes for special loading conditions. The span, or length, of the grating is measured in the direction of the bearing bars and includes banding. Panel spans can typically be up to 3 or 3.6 m, although longer lengths may be made to order depending on the grating type. Welded grating is manufactured in panels that are 6.1 or 7.3 m long, which are then cut toe the desired span.
Shorter spans are easier to handle.
The width of the grating is measured perpendicular to the direction of the bearing bars. Riveted grating can be manufactured with panel widths up to 1.5 m. Welded grating is manufactured in panels that are 0.9 m wide, which are then cut to the desired widths. Standard panel widths depend on grating type and bearing bar size. The use of standard widths results in a better looking application.
