B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 1

Yes, the five diamond Grip Strut plank is listed as OSHA compliant, and the diamond-punched, serrated surface is what does it: the openings shed water, oil, mud and ice so the footing stays non-slip in the conditions where a smooth plate would put someone on their back. It is the surface used for elevated walkways, mezzanine and crossover platforms, and access around equipment.

Mill-galvanized steel is the standard finish for covered, indoor and normally dry industrial areas. The zinc coating handles damp and washdown-adjacent conditions, but the cut ends and punched diamonds are raw steel and will show rust first in a constantly wet, coastal or chemically aggressive location. For those, specify a hot dip galvanized after fabrication or stainless plank instead.

It is formed from 12 gauge steel, which is the heavier of the common Grip Strut gauges and the one specified where there is real foot traffic plus tool and material loads. Gauge and the 1.5 inch channel depth together determine your allowable clear span, so set support spacing from the load table for 12 gauge at 1.5 inch channel rather than assuming a span.

The diamond count is the number of diamond rows across the width, so it sets how wide the piece is. Five diamond gives 11.75 inches of width, which is a walkway or platform plank. Two and three diamond pieces are narrower and get used as stair treads, ladder rungs and single-line crossovers. If you are decking a platform, the five diamond plank covers ground faster with fewer support points to fasten.

No. What ships is the plank itself, model 51512 12 GL, cut to 144 inches. Hold-down clips, saddle clips, bolts and any support steel are ordered separately, so budget those into the takeoff before the crew is on site with nothing to fasten with.

Yes. It is 12 gauge formed steel and cuts with a bandsaw, abrasive chop saw or plasma to fit a short run or trim around a column. Cut edges expose bare steel on a mill-galvanized part, so hit them with a cold galvanizing compound if the walkway sees any moisture.
