B-Line Eaton series Grip Strut stair tread, 360" Grating length, 7" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Stair tread, 14 gauge

The Grip Strut tread runs 360 inches long by 7 inches wide, with a 1.5 inch channel depth. That 30 foot length is a stock mill length meant to be cut to your riser width on site, not a pre-cut single step. The 7 inch walking width suits a single tread run; wider treads or landings take two sections side by side.

Yes. The B-Line Grip Strut tread is listed as OSHA compliant and is made for non-slip footing on stairs and walkways. The pierced, serrated channel surface sheds water, oil and debris so the traction surface stays exposed, which is why it gets specified for exterior stairs, mechanical platforms and industrial catwalks.

The tread is 14 gauge steel with a mill-galvanized finish, which gives corrosion resistance for exterior stairs, loading docks and unheated plant areas. Note that mill-galvanized means the sheet was galvanized before forming, so the cut ends and pierced edges are raw steel. On coastal or washdown sites, field-coat the cut ends or plan on a hot-dip or stainless product instead.

Grip Strut is a one-piece formed steel plank with a serrated, pierced traction surface, so it drains and self-cleans and gives grip in both directions. Bar grating is fabricated from cross bars and gives an open floor with higher open area, but the smooth bar edge is the walking surface unless you pay for serration. For a stair tread where slip resistance is the point, the formed Grip Strut channel is the simpler buy: it arrives as a single 7 inch wide plank with the 1.5 inch channel already formed for stiffness.

Yes, and that is the normal way it is used. At 360 inches the plank is bought as stock length and cut down to each riser width, so one piece can cover a full stair run. Cut with an abrasive saw or bandsaw across the 7 inch width, deburr, and touch up the exposed steel at the cut since the mill-galvanized coating does not wrap the new edge.
