B-Line Eaton series Grip Strut stair tread, 432" Grating length, 9.5" Grating width, Steel, 2" Channel size, Plain, Stair tread, 14 gauge

Yes. The Eaton B-Line Grip Strut stair tread is listed as OSHA compliant, and the perforated, serrated surface is what gets it there: it gives non-slip footing on stair treads where wet, oily or debris-covered surfaces are a fall risk. That makes it usable on industrial stairs, catwalk access stairs and mezzanine runs where an inspector will look for a slip-resistant walking surface.

The tread measures 9.5 inches across the grating width, with a 2 inch channel depth. A 9.5 inch tread width suits stairs designed for a nominal 9 to 10 inch tread run, which is the common industrial stair dimension. If your stringers are laid out for a deeper run, you would need a wider grating width rather than this one.

The finish on this tread is plain, meaning bare steel with no galvanized or coated protection. Indoors and dry, that is fine. Outdoors, on a wash-down floor, or anywhere with chemical exposure, plain steel will rust, so either field-paint it or specify a galvanized Grip Strut tread instead.

Channel depth is 2 inches, matching the 2 inch overall height of the tread. That 2 inch channel is the structural leg that carries the load and bolts to the stair stringer, so your stringer punching and the finished step height need to account for 2 inches of tread depth under the walking surface.

It is formed from 14 gauge steel. 14 gauge is the heavier of the common Grip Strut gauges, which is what you want on stair treads taking regular foot traffic and occasional tool or cart loads, rather than a light-duty walk surface used once a month.

Order it as Eaton B-Line part T42014N 36 BL. That is the identifier to quote when you are matching additional treads to a stair already built with Grip Strut, so the walking surface pattern and the 2 inch channel bolt pattern stay consistent across every step.

What ships is the Grip Strut tread itself in plain steel, 9.5 inches wide with a 2 inch channel. Fasteners and any stringer attachment hardware are separate, so budget bolts, nuts and washers per tread when you are pricing a full stair run.

Weight is listed at 3.8 lb, so a single installer can carry and position treads without a lift. For a retrofit on an existing stair, that means you can pull and replace worn treads one step at a time rather than staging the whole run.
