B-Line Eaton series Grip Strut two diamond plank, 144" Grating length, 4.75" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 14 gauge stee

Yes. The 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 requirement for elevated walkways, mezzanine access, and equipment platforms in industrial and institutional facilities.

It is 14 gauge steel with a plain finish, so there is no galvanizing or coating on it. Plain steel plank is meant for dry interior use or for jobs where you paint or coat it after install. For exterior, washdown, or corrosive locations, specify a galvanized or stainless version of Grip Strut instead.

Two diamond refers to the number of diamond-shaped serrated openings across the walking surface, which sets the plank width. At 4.75 inches wide, the two diamond plank suits narrow runs: single-file crossovers, access platforms alongside equipment, and filling out the edge of a wider run. For a full-width walkway or stair landing you would step up to a plank with more diamonds across, or lay multiple 4.75 inch planks side by side.

The plank has a 1.5 inch channel, and the overall height is also 1.5 inches. So when you set it across support angles or purlins, allow 1.5 inches of depth below the walking surface for the turned-down legs, plus whatever your attachment hardware needs. That depth is what gives a 12 foot piece its stiffness between supports.

No mounting hardware is part of the plank itself. Model 21514 12 BL is the 144 inch steel plank only, so order your hold-down clips, bolts, or welding consumables separately based on how you are fastening it to the supporting steel.

Grip Strut plank is light for its length. The 14 gauge steel plank is listed at 2.3 lb, so a 12 foot piece is a one-man carry, which is a large part of why crews use it for retrofit catwalks and service platforms where crane access is not practical.

Yes, it is 14 gauge steel plank and comes in a 144 inch stock length, so it is routinely cut on site to fit the span. Cut edges on plain finish steel are bare, so prime or paint them if the plank is going anywhere damp, since the material ships with a plain, uncoated finish.
