B-Line Eaton series Grip Strut stair tread, 432" Grating length, 11.75" Grating width, Aluminum, 2" Channel size, Stair tread, .080" Thick

Yes, the Grip Strut tread is listed as OSHA compliant and is intended for safe, sturdy footing anywhere a non-slip surface is required, which is the typical requirement for industrial stairs, catwalks and mezzanine access.

It's a 2 inch channel, and the product height is 2 inches, so the formed side channels give you a 2 inch leg to bolt or weld to the stair stringer or to a support angle. Allow for that 2 inch drop when you set your riser heights so the finished walking surface lands where the drawing calls for it.

This tread is aluminum, which is the choice where corrosion is the concern: exterior stairs, wastewater and treatment plants, food processing and wash-down areas, and coastal sites. Aluminum also keeps the weight down at 6.2 lb, so long pieces are handled by one person. Where the stair sees heavy wheeled loads or impact abuse, a steel or galvanized steel tread is the tougher pick.

It is 14 gauge aluminum at .080 inch thick. That thickness is what lets the pierced, serrated openings hold an edge for traction while the 2 inch formed channels carry the span between stringers.

What ships is the grating itself: a 432 inch long, 11.75 inch wide, 2 inch channel aluminum tread, model T52012 36 AL. Fasteners, support angles and any end or nosing plates are ordered separately to suit your stringer.

Grip Strut is a pierced and serrated one-piece plank, so the traction edges drain water, oil, ice and debris instead of holding it the way solid diamond plate does. Against welded bar grating, the advantage is weight and the formed 2 inch channel that acts as its own support, letting an 11.75 inch tread drop onto stringers without a separate frame. Bar grating is still the answer where you need a heavy uniform load rating over a wide span.
