B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 12

Each plank runs 144 inches long and 18.75 inches wide, with a 2 inch channel depth. That 12 foot length lets you cross a run in one piece instead of splicing, and the 18.75 inch width is a single-plank walking surface for catwalks, platform decking, and equipment access runs.

The Eaton B-Line Grip Strut plank is listed as OSHA compliant. The pierced diamond openings give a serrated, self-cleaning traction surface, which is why it gets specified where non-slip footing is required on platforms, stair treads areas, and mechanical access walkways.

Mill-galvanized steel is the standard finish here, which handles typical industrial and sheltered outdoor exposure. For constant moisture, chemical wash-down, or coastal salt air, most specs move to a hot-dip galvanized or stainless plank instead, since mill galvanizing leaves cut ends and pierced edges bare.

At 8.9 lb, a full 144 inch plank is a one-man carry up a ladder or onto a platform. That is one of the practical reasons crews pick pierced-and-formed plank over welded bar grating for mezzanine and catwalk decking.

Channel depth is what sets the clear span between supports. This one is a 2 inch channel in 12 gauge steel, suited to shorter support spacing on platforms, walkways, and equipment access decking. Deeper channel planks in the same family carry the same load over longer spans, so if your support steel is spaced wide, size up on channel depth rather than assuming the 2 inch will reach.
