B-Line Eaton series Grip Strut stair tread, 360" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Stair tread, 14 gauge

Yes, the Eaton B-Line Grip Strut stair tread is listed as OSHA compliant, and the serrated grip surface is intended for safe, sturdy footing where non-slip walking surfaces are required. That makes it usable on plant stairs, catwalk access stairs, and mechanical platform stairs where a slip-resistant tread is required by facility safety rules.

The tread measures 9.5 inches across the grating width with a 1.5 inch channel depth, so it covers the run of a typical industrial stair stringer in a single piece. If your run is deeper than 9.5 inches, you either need a wider tread width or two treads per step.

The finish is mill-galvanized steel, which is zinc coating applied to the coil before forming. It handles normal indoor industrial exposure and sheltered exterior use, but the cut edges and punched openings are left bare steel after fabrication, so in a wet, chemical, or wash-down environment you should expect edge rusting and either field-coat the cuts or specify a hot-dip galvanized or stainless tread instead.

14 gauge steel with a 1.5 inch formed channel is the common load-bearing configuration for industrial Grip Strut stair treads, and the 1.5 inch channel depth is what gives the plank its stiffness across the span rather than the sheet thickness alone. For heavy rolling loads or longer unsupported spans, step up to a deeper channel; for pedestrian stair traffic on normal stringer spacing, 14 gauge at 1.5 inch is the standard choice.

No hardware is included with the plank. It is the grating material only, 9.5 inches wide by 360 inches long, so bolts, end plates or angle clips, and any nosing needed to fasten to your stair stringers are ordered separately.
