Metal Bar Grating Stair Treads


Choose these stair treads for greater durability than metal plank grating stair treads. They have an open surface that prevents debris from accumulating. Nosing is textured for traction.
Stainless steel treads have better corrosion resistance than steel or aluminum.

Metal Bar Grating


Able to support heavier loads than plank grating, bar grating is good for trenches, mezzanines, walkways, work platforms, and floors. This grating has an open design that allows air, light, and debris to flow through. Cross bars hold the bearing bars in place; bearing bars help distribute weight and must rest on supports. Use Fasteners for Metal Bar Grating to secure.
Serrated grating provides maximum slip resistance.
Stainless steel grating has better corrosion resistance than steel or aluminum.
To Order: For custom sizes, please specify width and length. Note: Grating less than 17" long is reinforced with banding.

Plank Grating

Use plank grating for platforms, stair treads, ramps, and decks. Openings allow light to pass through and water to drain. Cut grating with a band saw, hack saw, circular saw, or shears. Use Fasteners for Plank Grating to secure.
Style A are serrated to provide maximum slip resistance.

Heavy Duty Metal Antislip Tape


Metal abrasives embedded in a metal backing allow this tape to last far longer than other antislip tape. It is often used to cover larger areas than other antislip tape, such as walkways and ramps. Tape has an adhesive backing and can be walked on immediately after installation.
Fold-Up Steps


Flip these steps down when you need them and fold them up when you don’t. They can be bolted onto a stable surface, such as a wall. All steps have a diamond-plate or serrated tread for maximum slip resistance.
Style 1 have a cutout and rounded edges that you can grab with your hand if needed.
Stainless steel steps are corrosion resistant. 304 stainless steel steps have good chemical resistance. 316 stainless steel steps offer the highest corrosion resistance and the best protection against chemicals and salt water.
Note: Check local, state, and federal codes, including OSHA, for safe operating practices.

Ladder-Style Steps


Good for use as ladder rungs, cut these steps to size with a metal-cutting saw and weld them in place. For a clean weld, match the step material to the surface you are welding to. These steps must be welded at each end with welds capable of supporting the rated capacity. For those 5 ft. and longer, the maximum cut length is 24". Shorter lengths support higher capacities.
Serrated steps give you maximum slip resistance and allow liquids and debris to pass through. Perforated steps are less slip-resistant than serrated steps but offer a more comfortable hand grip.
Note: Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
