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 st

The Grip Strut tread from the Eaton B-Line series is a 9.5 inch wide grating with a 2 inch channel size, so you get 9.5 inches of tread depth underfoot and a 2 inch nosing/channel height at the front. Grating length is listed at 432 inches. Match the 9.5 inch depth against your stringer spacing and riser layout before you commit to a run.

Yes. The Grip Strut stair tread is listed as OSHA compliant, and the pierced, serrated surface is intended for safe, sturdy footing where non-slip is required, which is what an industrial or plant stair needs. That makes it usable on maintenance platforms, mezzanine stairs and equipment access stairs where a facility inspector will be looking at slip resistance.

Mill-galvanized is a coating applied to the steel coil before forming, so the cut edges and pierced holes are left bare. It handles covered, dry or lightly humid industrial interiors well. For constant weather exposure, standing water, or chemical wash-down, specify a hot-dip galvanized-after-fabrication or stainless tread instead, because the exposed edges on a mill-galvanized part are where corrosion starts.

Each tread is listed at 5.4 lb, formed from 12 gauge steel. That is a one-man lift for setting and bolting treads on a stair run, which is the practical advantage of pierced plank grating over cast or welded bar grating treads.

Grip Strut is a single-piece pierced and formed 12 gauge steel plank with a 2 inch channel that acts as the structural depth, so it drains and self-cleans and rejects debris, mud and ice. Expanded metal treads tend to hold debris; welded bar grating is heavier and usually needs a separate nosing. Where the deciding factor is non-slip footing in an industrial traffic area, the serrated Grip Strut surface is the reason people spec it.

What ships is the formed steel tread itself. Carrier plates, end plates and the bolts or welds that tie the tread to your stringers are separate items and need to be specified for your stringer type and spacing. Plan on sourcing that fastening hardware with the order so the stair can be set in one trip.
