B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 2" Channel size, Stainless steel type 304, Grip Str

The plank runs 144 inches long (12 feet) with a 9.5 inch grating width and a 2 inch channel size, which is also its 2 inch height. So one plank gives you a 9.5 inch wide walking surface per run. For a wider catwalk or platform, lay planks side by side and multiply that 9.5 inches by the number of runs.

Model 42016 12 SS is type 304 stainless steel, formed from 16 gauge material. That is the version to spec for wash-down areas, food and pharma plants, coastal sites, water and wastewater, or anywhere a painted or plated carbon plank would rust out. If your run is in a dry indoor mechanical space, a plain or galvanized carbon steel plank covers it for less material cost.

The plank is listed as OSHA compliant. The four diamond pattern is the serrated, pierced-and-formed surface that drains liquid and debris through the openings and bites through oil, grease, ice and mud, which is what keeps the footing non-slip on a working platform, stair tread run or equipment access catwalk.

The 2 inch channel is the formed side leg on each edge of the plank, and it is also the overall 2 inch height. That leg is what rides on your cross members or bearer steel, so figure 2 inches of build-up above the top of your support framing when you are setting platform elevations or matching a landing height. It is also what carries the span, so keep your support spacing to whatever the load on the walkway calls for.

This one ships as a 144 inch plank, 9.5 inches wide. Formed channel plank is routinely field cut to length to suit the opening, so a long run can be cut down on site, but plan your layout in 9.5 inch width increments because the width is fixed by the forming. For 304 stainless, cut and deburr with stainless-dedicated blades and wheels so you do not embed carbon steel particles and start surface rust.

What you get is the plank itself, model 42016 12 SS, in 144 inch length. Hold-down hardware to fix the 2 inch side channels to your bearers is a separate line item, so add clamps or bolts to the order. In 304 stainless service, match the fasteners in stainless as well, since carbon steel bolts in a wash-down or coastal area will corrode and stain the plank.

Anywhere crews need sure footing on elevated or wet steel: mechanical mezzanines, rooftop equipment catwalks, stair and ladder landings, tank and vessel access platforms, pump house walkways, and machine guarding platforms. The plank is specified for safe, sturdy footing where non-slip is required, and the stainless 304 version is the one for wash-down, chemical or coastal exposure.
