B-Line Eaton series Grip Strut eight diamond plank, 120" Grating length, 18.75" Grating width, Steel, 3" Channel size, Plain, Grip Strut, 12 gauge

The Eaton B-Line eight diamond plank runs 120 inches long by 18.75 inches wide, with a 3 inch channel depth on each side. That 18.75 inch width is the plank itself, so for a walkway or platform wider than that you run multiple planks side by side. The 3 inch channel height is what sets your clearance above the supporting steel.

Yes. The Eaton B-Line Grip Strut eight diamond plank is listed as OSHA compliant and is made for safe, sturdy footing where non-slip surfaces are required, which is the usual reason it goes into catwalks, mezzanine platforms, and equipment access walkways.

Plain means bare steel with no coating applied. It is fine for dry interior service, but outdoors or in a washdown or corrosive area it will rust unless you paint or otherwise coat it after install. If the plank is going outside and you do not want to field-coat, specify a galvanized Grip Strut plank instead.

Diamond count is the number of rows of the pierced diamond openings across the width, so it sets how wide the walking surface is. Eight diamond gives an 18.75 inch wide plank, which is the size used for full-width catwalks and platform decking. Narrower diamond counts are what you use for stair treads and single-run access strips. All of them share the same non-slip formed surface.

The plank has a 3 inch formed channel on each side, and that channel leg is what sits on and gets fastened to your supporting members. Fasteners, hold-down clips, and the support framing are separate items and are not part of the plank, so order those with the job.

Yes, 12 gauge steel plank is commonly cut on site to suit the run, and the 120 inch stock length gets trimmed to fit between supports. Cutting exposes bare steel at the ends, and since this plank ships plain with no coating, treat cut edges the same way you treat the rest of the surface if the location calls for paint.
