B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 12 gauge steel

The Grip Strut three diamond plank runs 144 inches long (12 feet) with a 7 inch walking width and a 1.5 inch channel depth. It is formed from 12 gauge steel in a plain finish. That 12 foot length covers a full catwalk bay in one piece, and the 1.5 inch channel gives you the side leg that sits on and bolts down to your supports.

Yes. The B-Line Grip Strut three diamond plank is listed as OSHA compliant, and the diamond openings are punched to give non-slip footing on elevated walking and working surfaces. That is what a plant or facility safety buyer is specifying it for: safe, sturdy footing where non-slip is required.

Plain means bare steel with no galvanizing or coating applied. It is fine for dry indoor service, but outdoors, in washdown areas, or anywhere condensation collects it will need to be painted or coated after install, or you should specify a galvanized or stainless version instead. Check the environment before you order plain.

12 gauge is the mid-weight option in formed steel plank and is the common choice for maintenance access walkways, catwalks and platform decking. Load capacity depends on your support spacing, so set your span from the structural layout rather than the plank alone. If you are running long unsupported spans or vehicle traffic, step up to a heavier gauge or deeper channel than the 1.5 inch section here.

The 31512 12 BL is the plank only. Hold-down clips, saddle clips, bolts and any support steel are ordered separately, so build those into your takeoff before the crew shows up. The 1.5 inch side channel is what the clips grip against your bearing members.

Listed product weight is 4.1 lb, so a single 12 foot section is a one-man carry up a ladder or onto a platform. That matters when you are decking an elevated run and want to avoid rigging every piece.

Three diamond refers to the number of diamond opening rows across the walking surface, which sets the width. This one is a 7 inch wide plank on a 1.5 inch channel. Wider planks carry more diamond rows and cover more deck per piece; narrower ones suit stair treads and tight ledges. Pick the row count by the walking width you need to cover.
