B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 12 gauge

The four diamond Grip Strut plank runs 144 inches long (12 feet) with a 9.5 inch walking width and a 1.5 inch channel depth. It is formed from 12 gauge steel. Those three numbers are what you lay out against: 12 foot spans between supports get cut to suit, and the 9.5 inch width is the usable tread path per plank, so multiple planks get set side by side for a wider walkway.

Yes. The Eaton B-Line four diamond Grip Strut plank is listed as OSHA compliant and is made for safe, sturdy footing where non-slip walking surface is required. The pierced and formed diamond openings drain water and debris and give a serrated grip edge in every direction, which is why it gets used on mezzanine catwalks, stair treads, equipment platforms and mechanical rooms.

The finish on this one is Plain, meaning bare steel with no galvanizing or paint applied. Indoors in a dry mechanical space that is normally fine as-is. For exterior decks, wash-down areas, or anywhere it sees moisture or chemicals, you will want to paint or coat it after install, or specify a galvanized version of the same plank instead.

The diamond count is the number of rows of diamond openings across the tread width, so it sets how wide the walking surface is. This four diamond plank gives a 9.5 inch width with a 1.5 inch channel depth. Narrower two and three diamond sections are the ones used for single stair treads and tight runs; the four diamond is the plank you pick when you want fewer pieces to cover a walkway or platform.

Grip Strut plank has a 1.5 inch formed channel on each side, and that channel is what you fasten through, either bolting down to the support steel or clipping it with grating hold-down clips. No mounting hardware is included with the plank itself, so order clips, bolts or welding as a separate line when you spec the run.

Yes. It ships as a 144 inch length of 12 gauge steel plank and is routinely cut down on site with a bandsaw or abrasive chop saw to suit the opening. Cutting exposes bare steel at the ends, and since this plank comes in a Plain finish, touch up cut ends if the run is anywhere damp.

The plank is listed at 5 lb. It is light enough for one person to carry a full 144 inch length up a ladder or onto a platform, which is a large part of why fabricators use formed plank instead of welded bar grating on retrofit catwalks.
