B-Line Eaton series Grip Strut two diamond plank, 144" Grating length, 4.75" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 12 ga

The Grip Strut two diamond plank, model 22012 12 GL, is a 144 inch (12 foot) length with a 4.75 inch walking width and a 2 inch channel depth. The 2 inch channel forms the side rails, so the plank sits 2 inches above whatever it bears on. For wider walkways you run multiple planks side by side, since each one only gives you 4.75 inches of tread width.

Yes. The B-Line Grip Strut two diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is the usual reason it gets specified for catwalks, equipment platforms and stair treads.

The plank is steel with a mill-galvanized finish. Mill-galvanized is applied to the coil before forming, so the cut ends and punched diamonds are bare steel and will show surface rust in wet or corrosive service. It is fine for dry interior plant walkways and covered areas. For sustained outdoor exposure, wash-down, or chemical environments, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

No hardware is included with the 22012 12 GL plank. You get the 144 inch two diamond plank itself. Saddle clips, hold-down clips, or bolts through the 2 inch channel legs into your support steel have to be ordered separately, and you size them to your support spacing.

The diamond count tells you how many rows of punched, serrated diamonds run across the tread, which is what sets the walking width. This one is a two diamond plank at 4.75 inches wide, sized for a single-file walkway, a stair tread, or an equipment access run. Wider planks in the same family give more tread per piece for full platforms and landings. The channel depth, 2 inches here, controls how far the plank can span between supports, not how wide it is.

It is formed from 12 gauge steel, the heavier of the common Grip Strut gauges, and the stated product weight is 3.6 lb. One person can carry a stick, though at 144 inches long it is an awkward two-hand lift on a ladder.

Yes, the 12 gauge steel plank cuts with a band saw, chop saw with a metal blade, or torch, and the 144 inch stock length is meant to be cut down to your run. Because the finish is mill-galvanized, treat every cut end with a cold galvanizing compound if the plank sees any moisture, since the exposed steel at the cut has no coating.
