B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, 14 gauge

Yes. The five diamond Grip Strut plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required, which is what catwalks, mezzanine walkways and equipment platforms call for.

Mill-galvanized is the standard zinc coating applied to the steel coil before forming, so the cut ends and punched diamonds are left as bare steel. It holds up in covered or interior industrial settings. For constant weather exposure, chemical wash-down or coastal air, a hot-dip galvanized or stainless plank is the better call because it coats the cut edges too.

Each 120 inch plank weighs 4.2 lb, so a single installer can carry and set one without a lift. That low weight is also why Grip Strut gets used for retrofit walkways over existing structure where you do not want to add much dead load.

14 gauge is the thickness of the steel the plank is roll-formed from, and it is the heavier of the common Grip Strut gauges. Combined with the 1.5 inch channel depth, it is built as a walking surface for personnel traffic. Span capacity comes down to how far apart your supports are, so set your support spacing from the load you are carrying.

The diamond count tells you how many rows of the punched, serrated diamond pattern run across the plank, which is really a width call. Five diamond gives the 11.75 inch width, wide enough to use as a walkway or platform surface on its own. Narrower two and three diamond planks are for stair treads and catwalk stringers where you only need a foot's width. Same channel principle, same non-slip surface, just less coverage.

The plank itself is the walking surface only. You supply the supporting steel and the fasteners or hold-down clips that tie the 1.5 inch channel legs to your framing. Figure your support spacing first, then order clips or bolts to match, since nothing for mounting comes with the plank.

Yes, the steel plank is commonly field cut to fit a run. Keep in mind the mill-galvanized coating is applied before forming, so any cut you make exposes bare steel at the end. Touch cut ends up with a cold galvanizing compound if the walkway sees any moisture.
