B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 14 gauge stee

The Eaton B-Line Grip Strut five diamond plank runs 144 inches long and 11.75 inches wide, with a 2 inch channel depth. That is a 12 foot plank, so one piece spans a walkway bay end to end without a splice, and the 11.75 inch width is what you use to work out how many planks you need side by side for the tread width you want.

Yes. The five diamond Grip Strut plank is listed as OSHA compliant, and it is intended for safe, sturdy footing where non-slip surface is required. That is the reason it gets specified on catwalks, mezzanine walkways, equipment platforms and stair treads instead of plain plate.

Plain means bare steel with no coating applied. For interior, dry service that is normally fine, but for exterior or wash-down areas you would want a galvanized or coated version instead, since plain carbon steel will surface rust once it is wet. The plank itself is 14 gauge steel.

The diamond count describes how many rows of pierced, upturned diamond openings run across the width of the plank. Five diamond gives the widest single walking surface in the family, 11.75 inches here, so it is used for walkways and platform decking where you want fewer pieces across. Narrower diamond counts are used for stair treads, ladder rungs and single file catwalk runs. All of them use the same formed, non-slip diamond surface.

No fasteners are supplied with the plank. It ships as the formed 14 gauge steel plank itself, so plan on ordering your own hold down clips, saddle washers or weld attachment separately to fix the 2 inch channel legs to your supporting steel.
