2 Increased load performance(see charts pages 8-15) has been achieved through interlocking planks, stronger rung design and anexpanded selection of leg heights and material gauges. GRATE-LOCK lets you specify lighter gauge steelfor substantial material savings. More Sizes and GaugesGRATE-LOCK Grating provides one of the broadest line of Grating products of any manufacturer. Three (3) plank width options Four (4) plank height options Three (3) gauge options Lengths up to 24 feetInterlocking sections provide the strength you need for extra-wide designs. Full Line of AccessoriesOur line includes kickplates, hold-down clamps, attachment hardware and stair treads for completejob Bolt-Together AssemblyHelps save time in the field with GRATE-LOCK bolt-together slotted assemblies. Kickplates and planksections are prepunched. For additional ease, planks can be straight, curved, or angle cut with GRATE-LOCK Grating with ConfidenceWe have constructed our tables using the most stringent interpretation of the AISI standards.

6 Position Grating sectionsflat and square with ends bearing min. 11 2 on supporting structure. Keep Grating sections at least 1 4 away from vertical steel sectionsand 1 2 from concrete walls. Allow clearance at joints between sections of max. 1 4 at side channels and max. 3 8 at ends. Band randomcut ends and diagonal or circular cut exposed edges with a min. 1 8 thick bar welded at contact Grating Attachment - Attach Grating to supports without warp or deflection as plank application - Secure plank ends to supporting members at every point of contact. Use GRATE-LOCK Anchoring plank application - Secure plank ends to supporting members at every point of contact and intermediate Grating sectionswith at least one attachment each end of plank on alternate sides. For added rigidity, attach side channels of adjacent plank together(at mid-point of span). attachment - Secure side channels to supports by fusion welding with 1 8 fillet welds 1 long.
