B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

The plank runs 144 inches long by 11.75 inches wide, with a 1.5 inch channel size and a 1.5 inch overall height. That gives you a 12 foot run in a single piece, so a walkway or platform span up to 12 feet needs no splice.

Yes, the five diamond Grip Strut plank is listed as OSHA compliant, and the five diamond pattern is punched and formed for non-slip footing where safe, sturdy traction is required. That is the reason it gets specified on catwalks, mezzanine walkways, and equipment access platforms rather than plain sheet.

It is aluminum, in 12 gauge material. Aluminum planks are the usual pick where the surface is exposed to weather or a washdown or corrosive environment and you do not want to rely on a galvanized or painted coating staying intact, and where crews have to carry the plank up a ladder. If your spec calls for steel, this is not the right item.

Order it as Eaton B-Line part number 51510 12 AL. That designation breaks down as the five diamond plank profile in 12 gauge aluminum, 11.75 inches wide with a 1.5 inch channel, in the 144 inch length.

It does. The plank is formed with 1.5 inch deep side channels, which is also its overall 1.5 inch height, so the load-bearing depth sitting on your support members is 1.5 inches. Plan your support spacing and any toe board or handrail interface around that depth, and note the plank itself ships as the walking surface only, so clips or fasteners for tying it down to the framing are ordered separately.

Published weight is 1.88 lb. Aluminum at 12 gauge is light enough that a single worker can handle a 144 inch plank on a lift or ladder, which is a common reason crews choose aluminum over steel grating for retrofit platform work.
