B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 12 g

It runs 144 inches long and 7 inches wide, with a 2.5 inch channel size and a 2.5 inch height. That 12 foot length lets you span a walkway run with fewer joints, and the 7 inch width is a single-plank tread width, so for a wider platform you lay multiple planks side by side.

Yes. The three diamond Grip Strut plank is listed as OSHA compliant, and the pierced diamond surface is what does the work: it gives sure footing where a non-slip surface is required, including oily, wet or icy conditions on catwalks and equipment platforms.

The finish here is mill-galvanized steel, which is a zinc coating applied to the coil before forming. That suits covered, indoor and general industrial service well, including damp plant environments. Cut ends and pierced edges are left bare by the mill-galvanizing process, so for constant weather exposure or a corrosive wash-down area, specify a hot-dip galvanized or stainless plank instead.

This plank is formed from 12 gauge steel, the heavier of the common Grip Strut thicknesses, paired with a 2.5 inch channel depth. Gauge and channel depth together set the span you can run between supports, so size your support spacing off the manufacturer load table for a 2.5 inch, 12 gauge plank rather than assuming the full 144 inches is an unsupported span.

The diamond count tells you how wide the walking surface is. This one is a three diamond plank at 7 inches wide, which is the usual single-width tread for a catwalk, crossover or stair tread. If you need a narrower ladder-cage step or a wider platform surface, change the diamond count rather than trying to rip this plank down, since cutting through the pierced pattern leaves an unsupported edge.

Yes, steel plank is routinely cut to fit a run. Keep in mind the mill-galvanized coating does not cover the fresh cut, so brush a cold galvanizing compound on cut ends if the location sees any moisture. Ordering the 144 inch length and cutting down is common practice when the run does not fall on a stock length.
