B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut,

The plank runs 144 inches long by 18.75 inches wide, with a 1.5 inch channel depth. That 12 foot length covers a single span walkway or catwalk run without splicing, and the 18.75 inch width is a one-piece walking surface rather than something you gang together for narrow access. Channel height of 1.5 inches is what you allow for in your support framing.

Yes, the B-Line Grip Strut eight diamond plank is listed as OSHA compliant, and the diamond-pierced surface is what gets it there: the raised diamond openings give traction in all directions and shed water, oil and debris instead of holding it. That is the reason it gets specified for mechanical platforms, rooftop access runs and catwalks where a smooth plate would be a slip hazard.

The plank is 14 gauge steel with a mill-galvanized finish. Mill galvanizing is applied to the coil before forming, so the cut edges and pierced diamonds are raw steel. That is fine for covered or interior industrial use and normal rooftop service, but in a washdown, coastal or chemically aggressive environment you want a hot-dip galvanized after fabrication or stainless plank instead.

Eight diamond refers to the number of diamond rows across the width, and here that works out to 18.75 inches of walking surface in a single piece. Narrower Grip Strut sections (fewer diamond rows) are what you use for stair treads, ladder rungs and equipment platforms where you only need a foot's width. Pick the eight diamond plank when you want a full walkway width without seams down the middle.

The 81514F 12 GL is the plank only. Hold-down clips, saddle clips, bolts and any support steel are ordered separately, so budget those into the job. The 1.5 inch channel depth is the dimension your clips and framing have to suit.
