B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 2" Channel size, Stainless steel type 304, 16 gauge

Each plank of the Eaton B-Line Grip Strut four diamond series, model 42016F 10 SS, runs 120 inches long and 9.5 inches wide, with a 2 inch channel depth. For a walkway wider than 9.5 inches you run planks side by side; the 2 inch channel is what sits on your support steel, so set your bearing supports to suit that depth.

Yes. The Grip Strut four diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is the usual call-out for catwalks, mezzanine walkways, stair treads and equipment platforms in an industrial facility.

Type 304 stainless is the reason to pick this one. Model 42016F 10 SS is supplied in stainless steel type 304 rather than a painted or galvanized carbon finish, so it suits food processing, chemical, wastewater and coastal exposure where a galvanized plank would eventually bleed rust. The base material is steel at 16 gauge.

Light enough for one person to carry and set. The 120 inch plank is listed at 3.2 lb, which is why Grip Strut gets used for elevated walkways and retrofit platforms where you are hand-carrying material up a ladder instead of craning in bar grating panels.

The diamond count tells you how many rows of the pierced, non-slip diamond pattern run across the width, which sets the plank width. Four diamond gives a 9.5 inch wide walking surface on this model, so a single run makes a narrow catwalk or a wide stair tread; narrower diamond counts are used where you only need a single tread or a pipe-side toe walk. All of them share the same non-slip function.

Two inches. The plank's overall height is 2 in, matching the 2 inch channel size, so the walking surface sits 2 inches above the top of your support steel. Account for that when you are setting handrail heights or matching an existing walkway elevation.

It ships as a 120 inch plank and is 16 gauge steel, so it can be cut down on site to suit a shorter bay. Cutting a 304 stainless plank exposes bare edge, so deburr and passivate or seal the cut end if the run is in a wet or corrosive area.
