B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut,

Each plank runs 144 inches long by 18.75 inches wide, with a 2.5 inch channel depth. That is a 12 foot run, so a single plank spans most catwalk or platform bays without a splice, and you figure coverage at roughly 1.56 square feet per running foot of walkway.

Yes, the eight diamond plank is listed as OSHA compliant and is built as a non-slip walking surface. The pierced and formed diamond openings shed liquid, ice and debris and give traction from any direction of travel, which is what makes it common on mechanical platforms, catwalks and stair treads.

Mill-galvanized steel is a pre-galvanized coating applied to the sheet before forming, so the cut and pierced edges are left bare. It handles covered outdoor and general industrial exposure fine. For constant wet service, coastal air, or chemical wash-down, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

At 9.2 lb, a full 144 inch plank is a one-man carry up a ladder or scaffold. That is one of the practical reasons crews pick formed steel plank over bar grating for retrofit platform work in occupied buildings.

The eight diamond plank has eight rows of diamond openings across an 18.75 inch width, so it is a full walkway or platform panel. Narrower two, three or four diamond sections are stair treads and single-run catwalks. Pick by the finished width you need: one 18.75 inch plank makes a walkway on its own, or gang planks side by side for a wider platform.

It is formed from 12 gauge steel with a 2.5 inch channel depth. The 2.5 inch formed side channels are what carry the load, and heavier gauge with deeper channel means longer allowable spans between supports. Size your support spacing off the manufacturer's load table for 12 gauge at 2.5 inch depth and the live load your platform is rated for.

Allow at least 2.5 inches of depth below the walking surface. The plank's channel height is 2.5 inches, so that is how far the formed legs drop below the top of the tread before you add any supporting steel underneath.

The plank ships as the grating panel only, model 82512 12 GL. Hold-down clips, saddle clips, bolts or welding are specified separately based on your support steel. Order the attachment hardware with the plank so the crew is not held up on install day.

Yes. Formed steel plank cuts with a bandsaw or abrasive chop saw. Cut ends and any field holes expose bare steel on a mill-galvanized part, so touch them up with a cold galvanizing compound to keep corrosion out of the cut.
