B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 3" Channel size, Plain, Grip Strut, 12 gauge

Yes. The Grip Strut five diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where non-slip surfaces are required, which is the usual reason it gets specified for elevated walkways, mezzanine platforms, and equipment access catwalks.

The finish is plain steel, meaning no galvanizing or coating is applied. That is fine for dry interior service areas, but for exterior decks, wash-down areas, or anywhere with moisture, you want a galvanized or coated version of the plank instead, or you'll need to paint it after install.

12 gauge is the steel thickness the plank is formed from, and it is the heavier end of the range for perforated safety plank. Combined with the 3 inch side channels, that depth and gauge is what carries the load between supports on walkways and platform decking. Lighter gauges are used where spans are short and traffic is occasional.

The plank ships as the grating section alone, 120 inches by 11.75 inches in 12 gauge steel. Hold-down clips, saddle clips, and the bolts to fasten it to your support steel are ordered separately, so size those to your beam or channel supports before the crew shows up.

The diamond count describes how many rows of the pierced, raised-diamond non-slip pattern run across the width. Five diamond gives the 11.75 inch walking width here, which suits full walkway and platform decking. Narrower two or three diamond sections are the ones used for stair treads, ladder rungs, and tight equipment access where you only need a foot's width of tread.

The plank is listed at 7 lb, so a single 10 foot length is a one-man carry up a ladder or lift. That is one of the reasons perforated plank gets used over bar grating on retrofit catwalks where you cannot get heavy material into the space.
