B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 12 gauge

Yes, the four diamond Grip Strut plank is listed as OSHA compliant, and the pierced diamond surface is intended for safe, sturdy footing where non-slip is required, so it is used for catwalks, platforms and stair treads in industrial areas.

Correct. The 42012N 12 BL plank is carbon steel in a plain finish, meaning uncoated mill steel with no galvanizing or paint. For interior, dry locations that is usually left as is; for outdoor, washdown or corrosive service you want a galvanized or coated plank instead, since plain steel will rust.

The diamond count describes how many rows of pierced, raised diamonds run across the walking surface, which sets the width. Four diamond gives the 9.5 inch width here. Narrower two and three diamond planks are used for single stair treads and tight ledges; the four diamond width is the common choice for a continuous walkway or platform run because fewer planks cover the same area.

The plank is formed with a 2 inch deep channel down each side, which gives it 2 inches of overall height and lets it sit across supports and bolt or weld through the side legs without a separate frame. Space your supports so the plank bears on both channel legs at each end.

The 12 gauge, 9.5 inch wide plank is listed at 5.4 lb, so a single 12 foot length is a one or two man lift and light enough to hand up a ladder or lift into an overhead run without rigging.

No. What ships is the formed plank itself. Hold-down clips, bolts or weld attachment to your framing are ordered separately, so plan the fastening hardware for the number of support points in your run.
