B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 5" Channel size, Galvanized, Grip Strut, 10 gauge

The five diamond plank runs 144 inches long and 11.75 inches wide, so a single piece spans a 12 foot walkway run and covers just under a foot of width per plank. Lay planks side by side to build out wider platforms or catwalks.

Channel depth is 5 inches, which matches the stated product height of 5 inches. That is the vertical space the plank itself occupies on top of your supports, so add it to your framing height when setting finished walking surface elevation.

Grip Strut five diamond plank is listed as OSHA compliant and is made for safe, sturdy footing where non-slip is required. The pierced diamond openings shed liquid, ice and debris and give traction from any direction of travel, which is why it gets used on catwalks, mezzanine walkways and equipment platforms.

It is 10 gauge steel with a mill-galvanized finish, so the zinc coating handles outdoor exposure, damp plant areas and wash-down duty far better than bare or painted steel. For heavy chemical exposure or coastal salt, specify a stainless or specialty-coated grating instead.

Each 144 inch plank weighs 17.5 lb, light enough for two people to set by hand on a mezzanine or tower run without a lift. That figure is also what you add per plank when tallying dead load on the supporting steel.

Diamond count describes how many rows of pierced openings run across the walking surface. Five diamond is the wide plank at 11.75 inches, meant to cover a walkway or platform with fewer pieces and fewer support points across the width. Narrower channels in the same Grip Strut line are used for stair treads, single-file crossovers and tight ledges where a full plank will not fit. Both give the same pierced non-slip surface.

Yes. It ships as a 144 inch steel plank and is routinely cut to fit a run in the field. Cutting removes the galvanizing at the cut edge, so touch up bare steel with a cold galvanizing compound if the walkway is outdoors or in a wet area.
