B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Aluminum, 3" Channel size, Grip Strut, .100" Material thick

The Grip Strut three diamond plank in aluminum runs 144 inches long, 7 inches wide, with a 3 inch channel depth. That 144 inches is a full 12 foot length, so one plank spans a 12 foot walkway run without splicing. For wider walking surfaces you run planks side by side; each one adds 7 inches of width.

Eaton B-Line lists the three diamond Grip Strut plank as OSHA compliant. The pierced diamond openings shed liquid and debris and the raised, serrated edges around each opening grip the boot from any direction, which is what makes it acceptable as non-slip footing on catwalks, platforms and stair treads.

The plank is aluminum, so it won't rust the way bare or painted steel does outdoors or in wet washdown areas. The tradeoff is aluminum is the lighter, lower-strength material compared with steel or stainless versions of the same three diamond plank, so check your span and load before you commit. Watch for galvanic issues if you're bolting aluminum to dissimilar metal supports.

It's 12 gauge material, .100 inch thick aluminum. That's the mid-weight option in the Grip Strut line; lighter gauges are used for light-duty crossovers and heavier material for higher loads or longer unsupported spans. If your support spacing is wide, confirm the span rating for 12 gauge aluminum against your design load before you specify it.

Grip Strut plank is a one-piece formed section with the channel legs built in, 3 inches deep here, so it acts as its own support member between beams and drops straight onto the structure. Bar grating is a welded panel that generally needs a supporting frame under it. For catwalks, mezzanine walkways and stair treads where you want fast install over widely spaced supports, the formed plank is the simpler route.

No hardware is included with the 33010 12 AL plank; you're buying the plank itself. Plan on separate saddle clips, hold-down clamps or bolts to fasten the 3 inch channel legs to your supports, and order those to suit your beam flange.

Yes. Aluminum plank at 12 gauge is light enough for single-person handling on most jobs, and the product weight is listed at 1.68 lb. It's a common reason crews pick aluminum over steel for rooftop and elevated platform work where you're hauling material up a ladder or hatch.

Aluminum plank cuts readily on site with a circular saw and a metal-cutting blade, which is how most crews trim a 144 inch length to a shorter opening. Deburr the cut end and, if the run is exposed, cap or trim it so nobody catches a boot on the open channel.
