B-Line Eaton series Grip Strut stair tread, 576" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Stair tread, 12 gauge

The Grip Strut stair tread has a 9.5 inch grating width and a 576 inch grating length, with a 2 inch channel height. The 9.5 inch dimension is the tread depth underfoot; the 576 inch figure is the material length, so it is cut to the stair width you need rather than supplied as a single fixed riser.

Yes. The 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 is required. That makes it usable on plant, mezzanine, and platform stairs where a slip-resistant walking surface is required.

The tread is steel with a mill-galvanized finish. Mill galvanizing gives the base steel a zinc coating suitable for general industrial and sheltered exterior use, but the cut ends are raw steel and will need touch-up in wet or corrosive service. For constant wash-down or chemical exposure, a heavier hot-dip or stainless grating is the better call.

It is formed from 12 gauge steel with a 2 inch channel depth. The 2 inch formed channel is what carries the load between stringers, and 12 gauge is the common industrial weight for plant stair treads in daily foot traffic. For long unsupported spans or rolling loads, confirm your stringer spacing against the channel depth.

Order it by manufacturer part number T42012N 48 GL from Eaton B-Line. That designation covers the 12 gauge mill-galvanized steel Grip Strut tread with the 2 inch channel and 9.5 inch grating width.

What ships is the Grip Strut tread itself, 9.5 inches wide in 12 gauge mill-galvanized steel. Nosing, end plates, and the bolts or welds that tie it to your stringers are separate items, so budget fasteners and any end closure as part of the job.

Product weight is listed at 5.4 lb, so a single tread is a one-person lift and can be carried up a stair run without rigging. The 12 gauge steel gives it stiffness without the mass of bar grating.
