B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 12 ga

Yes. The four diamond Grip Strut plank is listed as OSHA compliant, and the diamond-pierced surface is intended for safe, sturdy footing where non-slip walking surface is required, such as catwalks, mezzanine walkways, and equipment access platforms.

The plank is steel with a mill-galvanized finish, which is zinc coating applied to the coil before forming. That suits covered and general industrial use, and moderate outdoor exposure. The cut and pierced edges are bare steel after fabrication, so in constantly wet, coastal, or chemical wash-down areas a hot-dip galvanized or stainless grating is the better call.

6.1 lb per plank, so a single installer can carry and set a 10 foot length by hand. That light weight is the usual reason crews pick perforated plank over bar grating for retrofit walkways where the supporting structure is already in place.

It is formed from 12 gauge steel, the heavier of the common Grip Strut gauges. Gauge and the 3 inch channel depth together set how far the plank can span between supports, so heavier gauge plus deeper channel means fewer intermediate supports on a walkway frame.

The diamond count describes how many rows of pierced diamonds run across the walking surface, which sets the width. Four diamond gives a 9.5 inch wide plank, a common single-plank width for a narrow catwalk or a stair tread run. Narrower two and three diamond sections are used for stair treads and tight ledges; wider sections cut down the number of pieces on a broad platform.

The 43012 10 GL is the plank only. Hold-down clips, bolts, or self-drilling fasteners to secure the channel legs to your support framing are separate items and need to be ordered alongside it.
