B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 5" Channel size, Mill-galvanized, 10 gauge

Yes. The five diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is why it shows up on catwalks, mezzanine walkways, platforms and equipment access runs in industrial plants.

Mill-galvanized steel is the finish here, meaning the sheet is galvanized before forming, so the cut edges and pierced diamond openings are raw steel. That is fine for covered industrial interiors and normally dry exterior use, but in constant wet, wash-down or corrosive chemical service you want a hot-dip galvanized after fabrication or stainless plank instead.

Each 144 inch plank weighs 17.5 lb, light enough for two people to carry up a ladder or pass onto a mezzanine without rigging. The weight comes from 10 gauge steel formed into a 5 inch deep channel section rather than solid bar, which is what keeps it light while still spanning.

Five diamond describes how many rows of pierced, upturned diamond openings run across the width of the plank. More diamond rows across a wider plank, five rows here at 11.75 inches wide, means more gripping edges underfoot and better drainage of water, oil and debris through the surface. Narrower Grip Strut sections carry fewer rows.

Grip Strut plank is a formed 10 gauge steel section with pierced diamond openings, so the entire walking surface is a gripping edge and it drains. It is lighter per foot than bar grating, a 12 foot plank runs 17.5 lb, and the 5 inch side channels let it span between supports on its own. Bar grating is the choice when you need heavy rolling loads or very long unsupported spans. For foot traffic access runs, stair treads and platforms where slip resistance is the driver, the diamond plank is the usual pick.

Yes, the 144 inch plank is 10 gauge formed steel and can be cut down on site with a metal-cutting saw. Because the finish is mill-galvanized, applied to the sheet before forming, any field cut leaves bare steel, so touch the cut ends with a cold galvanizing compound if the plank sees any moisture.
