B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Aluminum, 2" Channel size, .080" Material thickness

The Grip Strut five diamond plank, model 52012 12 AL, runs 144 inches long and 11.75 inches wide with a 2 inch channel depth. That 12 foot length covers a full catwalk run or platform bay in one piece, and the 2 inch side channels give the plank its stiffness over the span.

Yes. The five diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is what plant walkways, catwalks, and mezzanine access platforms are usually specced against.

The plank is aluminum, so it won't rust the way a plain carbon steel plank does, which is why aluminum gets picked for coastal sites, wash-down areas, water treatment, and rooftop runs. It is formed from 14 gauge material with 2 inch channels for rigidity.

The diamond count describes how many rows of the serrated non-slip openings run across the width of the plank. Five diamond gives the widest single piece in the family at 11.75 inches, so you cover a walkway with fewer pieces and fewer support connections. Narrower diamond counts are the choice for stair treads and tight ledges where 11.75 inches is more width than the opening allows.

What ships is the plank itself, model 52012 12 AL, 144 inches of aluminum five diamond planking. Hold-down clips, saddle washers, and the bolts that tie it to your support steel are ordered separately, so add them to the same order if the run is going up fresh.

Allow 2 inches below the walking surface for the plank itself. The formed side channels are 2 inches deep, so that is the height the plank adds on top of whatever beam or angle you are setting it on. Factor it in when you are matching a landing height or clearing a doorway threshold.
