B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

Aluminum, in 12 gauge. That makes it the choice for wash-down areas, coastal sites, water treatment plants and rooftop access where a plain steel or galvanized plank would eventually bloom rust. It also means no field touch-up of cut ends for corrosion, which you would have with galvanized steel.

The B-Line Grip Strut three diamond plank is listed as OSHA compliant. It's a serrated diamond-pattern surface intended for safe, sturdy footing where non-slip is required, which is what puts it on catwalks, ladder platforms, stair treads and equipment access routes in plants and utility buildings.

It describes how many rows of the diamond openings run across the width of the plank. Three diamond gives the 7 inch walking width on this one, with the 1.5 inch channel formed down each side. Wider planks in the family carry more diamond rows; narrower ones fewer. If you're matching existing plank on a catwalk, count the rows across and check the overall width before ordering.

Yes. It ships as a 144 inch plank and is routinely cut down for platforms, stair treads and short access runs. Being 12 gauge aluminum rather than steel, it cuts with a circular saw and a non-ferrous blade, and cut ends don't need corrosion touch-up the way galvanized steel does.

No hardware is included with the 31510 12 AL plank. It ships as the plank alone, so plan on ordering hold-down clips, saddle clips or bolts separately to fasten the 1.5 inch channel legs down to your support steel. Order those at the same time so the crew isn't waiting on fasteners with plank already on the roof.

The diamond-punched face is the walking surface and the two 1.5 inch channel legs turn down, so the plank sits like a shallow inverted channel bridging your supports. Those legs are what carries the span and what you fasten through. Overall height of the section is 1.5 inches, which is what you deduct when setting your support elevations to land the finished walking surface flush.
