B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Aluminum, 3" Channel size, Grip Strut, .100" Thick

The plank runs 120 inches long by 9.5 inches wide, with a 3 inch channel size and a 3 inch overall height. That 10 foot length is a single piece, so plan your support spacing and cut points before ordering rather than butting short sections together across a walkway.

The four diamond Grip Strut plank is listed as OSHA compliant. The serrated diamond openings are what do the work: they shed water, oil and debris and give grip from any direction of travel, which is why it gets specified for mechanical platforms, stair treads and rooftop access walks.

The plank is formed with 3 inch deep channel legs, and that depth is what carries the load between supports. The legs need to bear on your framing members, not hang past them, so lay out your cross members to the span the 3 inch section is rated for in your load case. It also means the finished walking surface sits 3 inches above the supporting steel, which matters if you are matching an existing deck elevation or a door threshold.

The diamond count describes how many rows of the serrated openings run across the width of the plank, so it sets the walking width. This one is a four diamond at 9.5 inches wide. Narrower two and three diamond planks are used for single runs beside equipment or as stair treads; four diamond planks get ganged side by side to build a full width platform or catwalk.

No fasteners are included with model 43010 10 AL. You order the plank itself and attach it with saddle clips, hold-down clamps or through-bolts to your supporting steel, so add that hardware to the same order if you are building out a platform.

Yes. It ships as a 120 inch aluminum length and is routinely cut down in the field with a metal-cutting saw to suit the span between supports. Cut ends are usually laid over a bearing member so the channel legs land fully supported.
