B-Line Eaton series Grip Strut stair tread, 432" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Stair tread, 12 gauge

The Grip Strut tread measures 9.5 inches across the walking surface with a 2 inch channel size, and the channel depth matches the 2 inch product height. That 9.5 inch width covers a standard single-tread stair run, and the 2 inch channel is what gives the tread its stiffness between stringers.

Yes. The B-Line Eaton Grip Strut stair tread is listed as OSHA compliant, and the perforated, serrated surface is intended for safe, sturdy footing where non-slip is required. That is the reason it gets specified on plant catwalks, mezzanine stairs and exterior equipment access stairs.

The mill-galvanized steel finish gives corrosion resistance for typical outdoor and damp industrial use, such as exterior stairs and equipment platforms. Mill-galvanized means the zinc coating was applied to the coil before forming, so cut ends and punched openings are raw steel and will show surface rust over time in harsh or coastal exposure. For those conditions, spec a hot-dip galvanized or stainless tread instead.

What ships is the tread itself, B-Line Eaton model T42012N 36 GL, in steel with a mill-galvanized finish. Bolts, nuts and any stringer clip angles are a separate line on the order, so add them when you quote the stair.

Each tread weighs 5.4 lb, so a single installer can carry and set it without a lift. Fabrication is 12 gauge steel, which is the common weight for stair treads carrying foot traffic and occasional tool loads.
