Metal Bar Grating Stair Treads


Smooth Aluminum	Serrated Aluminum	Mounting Dimensions

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.

Aluminum—Aluminum treads are more corrosion resistant than galvanized steel. Plus, they're lightweight, nonsparking, and nonmagnetic.

Stair Nosing


Style A	Style B

Screw nosing into place to protect the front portion of the stair and provide a slip-resistant surface. Construction adhesive (sold separately) is for use between nosing and the front edge of the stair to prevent cracks.

Style A—Style A are for use on wood or concrete stairs. For wood stairs, use #10 wood screws. For concrete stairs, use _3/16" diameter tapping screws. Style A have a front channel filled with grit and a rear abrasive strip for added traction.

Style B—Style B can be installed in fresh concrete as well as on existing concrete stairs. Use concrete screws for _1/4" diameter countersunk holes. Nosing has five channels filled with an abrasive grit compound for excellent traction and slip resistance.

Ladder-Style Steps

Serrated Step

Perforated Step

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.

Note: Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Serrated Step—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.

Step Handles

Weld On

Add a hand- or foothold for easier access to your vehicle or equipment. These handles have a textured surface that’s easy to grip and keeps you from slipping.

Note: Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Weld On—Weld-on step handles can be installed with the side guards facing up or down. Mount them up to keep your toe from slipping; mount them down to maximize the surface area on top of the handle. For a clean weld, choose a handle that’s the same material as your mounting surface.
