B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 10

Each plank of the Eaton B-Line Grip Strut five diamond series, model 53010 12 GL, runs 144 inches long by 11.75 inches wide, with a 3 inch channel depth. The 3 inch channel is the structural leg that carries the load, so support points are set by your framing layout and the plank is cut or laid to suit. For a wider walk surface, lay multiple 11.75 inch planks side by side.

Yes. The five diamond Grip Strut plank is listed as OSHA compliant, and the diamond openings in the 10 gauge steel surface are formed to give non-slip footing where safe, sturdy footing is required. That is what makes it a common choice for catwalks, mezzanine walkways, platform decking and stair treads in industrial and MRO settings.

Mill-galvanized is the finish on this plank, meaning the steel was galvanized before forming, so the cut and punched edges are bare. It handles normal indoor industrial humidity and covered exterior use, but for continuously wet, washdown or corrosive chemical exposure you want a hot dip galvanized after fabrication or stainless plank instead, where every edge is coated.

The diamond count describes how many rows of diamond openings run across the walking surface, which sets the width. Five diamond gives an 11.75 inch wide surface, wide enough for a single walkway or platform decking run. Narrower two or three diamond planks are the ones used for stair treads and tight ledge or crossover walkways. Same 10 gauge steel forming and same non-slip surface, just less width per piece.

Yes, the plank is supplied as the formed grating section only. Model 53010 12 GL includes no hold down clips, saddle clamps or bolts, so specify the attachment hardware to match your supporting steel. The 3 inch channel leg is what the clips grip, so size the hardware to that channel depth.

A full 144 inch plank weighs 15.4 lb. That is light enough for one person to carry and set, which is part of why open-grip plank gets used over solid steel plate on elevated platforms, and it keeps added dead load on a mezzanine or rooftop frame low.

10 gauge is the heavier end of formed steel plank and is the usual pick for pedestrian platforms, catwalks and maintenance access where the frame supports are on regular centers. Combined with the 3 inch channel depth it is a structural walking section, not a light tread cover. For forklift traffic or heavy point loads, move to bar grating or plate rather than formed plank.

Yes, the 144 inch steel plank is field cut with a metal chop saw or band saw to suit the opening. Because the finish is mill-galvanized, the cut end will be bare steel, so brush on a zinc rich cold galvanizing compound after cutting if the location sees any moisture.
