B-Line Eaton series Grip Strut eight diamond plank, 120" Grating length, 18.75" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .080" Thick

The Grip Strut eight diamond plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required. The diamond openings are pierced and formed so each edge bites into the sole of a boot, which is what keeps traction in oil, ice, or mud.

This plank is aluminum, 14 gauge, at .080 inch thick. Aluminum is the choice where you have weather exposure, washdown, coastal salt air, or chemical atmosphere and you do not want to maintain a galvanized or painted steel surface. Go to steel plank instead when you need higher load capacity over the same span or the run will see heavy rolling loads. For an electrical platform, catwalk, or mezzanine walkway outdoors, the aluminum version is the one that stays serviceable without recoating.

It is an eight diamond plank, meaning eight rows of pierced diamond openings across the 18.75 inch width. More diamonds across means more width per piece, so you cover a walkway with fewer planks and fewer support points at the edges. Narrower two, three, or five diamond channel sections are what you use for single stair treads or tight catwalk ledges.

The 81512 10 AL is supplied as the plank itself. Hold-down clips, saddle clips, or bolts to secure the plank to your stringers or support steel are ordered separately, so add the attachment hardware to the same order. The 1.5 inch channel depth is what determines which clip profile seats correctly over the side channel.

Not as supplied. At 18.75 inches wide and 120 inches long, this is a walkway and platform plank, not a tread. Stair treads use short, narrow Grip Strut channel sections cut to the stair width with an integral nosing and end plates for bolting to the stringer. Use this plank for landings, catwalks, mezzanines, and equipment platforms instead.

Yes. The aluminum construction keeps the weight down enough that a single worker can carry and set a 10 foot length, which is the practical reason crews spec aluminum plank for elevated retrofit work where you are hauling material up a ladder or through a hatch. Steel plank of the same footprint takes two.

Yes, .080 inch aluminum at 14 gauge cuts with a circular saw and a non-ferrous blade, so a 120 inch plank can be trimmed on site to suit a platform opening. Cut ends should land on a support member, and deburr the diamond edges before anyone walks it.
