Grate-Lock® Interlocking Safety Grating


GRATE-LOCK™ Grating is an easy-to-install system of interlocking grating planks, treads and accessories that provides safe, sturdy footing for mezzanine floors, platforms, walkways and other applications where non-slip performance is required. Hundreds of sole-gripping dimples insure a safe surface in all kinds of of weather and environments. The grating is available textured for safer working surfaces, non-textured for wheeled traffic or rack decking.

Cost-saving design improves loading performance - The unique design of GRATE-LOCK Grating gives you more design options - at less cost than other grating systems. Increased load performance (see charts) has been achieved through interlocking planks, stronger rung design and an expanded selection of leg heights and material gauges. GRATE-LOCK Grating lets you specify lighter gauge steel for substantial material saving.
More sizes, gauges - GRATE-LOCK Grating provides the broadest line of products of any manufacturer. Available in three plank widths, four plank heights, three gauges and lengths to 24'. Interlocking sections provide the strength you need for extra-wide designs.
Full line of accessories - Our line includes kickplates, hold-down clamps, attachment hardware and stair treads for complete job design.
Fast bolt-together assembly - Save time in the field with GRATE-LOCK bolt-together slotted assemblies. Kickplates and plank sections are prepunched. For additional ease, planks can be straight, curved or angle cut with hand tools.
Specify GRATE-LOCK Grating with confidence - We have constructed our load tables using the most stringent interpretation of the AISI standards: Our safe allowable loads guard against harmful local distortion as well as failure.
