B-Line Eaton series Grip Strut eight diamond plank, 120" Grating length, 18.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, 12 gauge

The B-Line Eaton Grip Strut eight diamond plank runs 120 inches long by 18.75 inches wide, so one piece covers a 10 foot run of walkway just over a foot and a half wide. For wider platforms, planks are laid side by side to build out the width.

Yes. The eight diamond Grip Strut plank is listed as OSHA compliant and is intended for safe, sturdy footing where non-slip surfacing is required, which is what puts it on catwalks, mezzanines, platforms and stair treads in industrial and utility work.

Channel size is 1.5 inches, and overall height is the same 1.5 inches. That is the depth of the formed channel section, so allow at least an inch and a half below the walking surface for the plank itself before you add support steel.

The plank is steel with a mill-galvanized finish, which is zinc applied to the coil before forming. That suits covered industrial interiors and normally dry outdoor structures. Cut ends and punched openings are bare steel, so in a wash-down bay, coastal site or chemical area you want a hot-dip galvanized or stainless grating instead, or you cold-galvanize the field cuts.

This plank is formed from 12 gauge steel, the heavier of the common Grip Strut thicknesses, which is what you specify for longer spans and heavier foot and cart traffic. Lighter 14 and 16 gauge planks of the same profile want supports closer together. Set your support spacing from the load table for the span and live load you are carrying.

Diamond count describes how many rows of the serrated diamond openings run across the width of the piece. Eight diamonds across gives this one an 18.75 inch width, wide enough to use as a walkway or platform plank on its own. Narrower two, three and four diamond pieces are sized for stair treads and single-line catwalks. If you are covering a platform, the eight diamond plank means fewer pieces and fewer support connections.

Order it by model 81512 10 GL, which is the 12 gauge, 1.5 inch channel, mill-galvanized eight diamond plank at the 120 inch length. It ships as a full 10 foot plank; field cutting to your opening is done on site, and fasteners, hold-down clips and support framing are separate.

It weighs 8.5 lb, so a single 10 foot plank is a one-man lift and hoist, awkward for length rather than heavy. That matters when you are handing planks up to a mezzanine or working off a lift.
