B-Line Eaton series Grip Strut ten diamond plank, 144" Grating length, 24" Grating width, Steel, 3" Channel size, Plain, Grip Strut, 14 gauge

The Eaton B-Line Grip Strut ten diamond plank is listed as OSHA compliant, and the serrated diamond openings give the non-slip footing that walking and working surfaces require. That's what puts it on elevated platforms, stair treads runs, mezzanine walkways and equipment access catwalks where a plain plate deck would fail a slip check.

Plain means bare, uncoated steel. There is no zinc or paint on it, so it is suited to dry interior use or to jobs where you intend to paint or coat it after fabrication. For exposed outdoor or washdown locations, specify a galvanized Grip Strut instead rather than putting plain steel up and hoping paint keeps up with it.

Ten diamond describes how many rows of the pierced, serrated diamond pattern run across the width of the plank. On this one that pattern spans a 24 inch width. More diamonds across means a wider single walking surface, so you cover a given walkway width with fewer planks and fewer support connections than you would with narrow two or three diamond tread sections.

It's formed from 14 gauge steel. The 3 inch deep channel legs on each side are what carry the load over a span, not the sheet thickness alone, so support spacing should follow the load and span you are designing for rather than being assumed from the gauge.

Allow at least 3 inches below the walking surface. The plank's overall height is 3 inches, which is the depth of the side channels that hang below the diamond tread. That dimension also sets the step-up at any doorway or landing where the plank meets an existing floor.

Yes, Grip Strut plank is routinely cut to length on site to suit a walkway run. Keep in mind the finish is plain, uncoated steel, so any cut edge is bare and should be primed or coated along with the rest of the plank if the location calls for it.
