B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 12

The four diamond Grip Strut plank runs 120 inches long by 9.5 inches wide, with a 1.5 inch channel height. That 10 foot length covers a full walkway run or catwalk bay in one piece, and the 9.5 inch width means you lay planks side by side to build out a wider platform. Support spacing has to suit your load, but the plank itself gives you a 10 foot working length to plan around.

Yes. The Grip Strut four diamond plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required. The pierced diamond openings shed liquid, ice and debris and give traction from any direction of travel, which is what makes it common on catwalks, mezzanine walkways and equipment platforms.

It is formed from 12 gauge steel with a mill-galvanized finish. Mill-galvanized is zinc applied to the coil before forming, so the cut ends and pierced edges are left bare steel. That is fine for covered or interior industrial areas and light exterior exposure, but for a corrosive or constantly wet environment you want a hot-dip galvanized after fabrication or stainless plank instead.

The 41512 10 GL is the plank only. Hold-down clips, bolts or self-drilling screws to fix it to your bearing steel are ordered separately, so add the attachment hardware to your order before the crew shows up. The 1.5 inch channel leg is what the fastener passes through at each support point.

Diamond count on Grip Strut refers to how many rows of pierced diamonds run across the plank, and it sets the width. The four diamond version here is 9.5 inches wide with a 1.5 inch channel, which is the common choice for building up walkways and platforms from multiple planks. Narrower two and three diamond planks are used for stair treads and tight ladder landings where a full 9.5 inch board will not fit.

Yes. The plank is listed at 5 lb, so a single installer can handle a 120 inch length on a lift or mezzanine deck without rigging. That light handling weight is one reason Grip Strut gets used for retrofit walkways over existing equipment where crane access is not available.

It can be cut down, and on most jobs it has to be since walkway bays rarely land on an even 120 inches. Cut it with an abrasive saw or bandsaw through the 12 gauge steel, then touch up the cut with a cold galvanizing compound, because mill-galvanized stock has no zinc on a freshly cut edge.
