B-Line 32512N 12 GL Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 12 gauge

The 32512N three diamond plank runs 144 inches long by 7 inches wide, with a 2.5 inch channel size (2.5 inch height including the side channels). So one plank spans a 12 foot run and gives you a 7 inch walking width, which is why it typically gets used two or three abreast for a full catwalk width.

Yes. The 32512N Grip Strut plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required. The three diamond serrated pattern is the slip resistant element, so it suits walkways, platforms and access ways in plants and utility spaces.

The 32512N is steel with a mill-galvanized finish, which is zinc coating applied to the coil before forming. That gives ordinary indoor and sheltered outdoor corrosion protection, but the cut edges and punched openings are bare steel after fabrication. For constant wetness, washdown, or a corrosive chemical environment, specify a hot-dip galvanized after fabrication or stainless plank instead.

12 gauge is the steel thickness of the formed plank, the heavier of the common Grip Strut gauges. The heavier the gauge, the longer the clear span between supports for a given load. If your support spacing is wide or you are carrying rolling loads, confirm the span and load table for your spacing rather than assuming 12 gauge covers it; for light foot-traffic platforms on close supports a thinner gauge plank is the usual pick.

Order Eaton B-Line part number 32512N 12 GL. That number carries the 7 inch grating width, 144 inch length, 2.5 inch channel, 12 gauge steel and mill-galvanized finish all in one designation, so the gauge and finish suffixes must be included when you quote it.

No fasteners are included. The 32512N is the formed plank only, 144 inches long with 2.5 inch side channels. You fasten it down through those channels with saddle clips, hold-down clips or self-drilling screws sized to your support steel, and those are ordered separately.

Each 144 inch plank weighs 4.9 lb, so a single installer can carry and set one by hand. That low weight is one reason 12 gauge Grip Strut gets used for retrofit walkways and catwalk decking where you cannot crane in heavy bar grating.

Yes, the 144 inch plank can be field cut to length. Because the finish is mill-galvanized, the cut is bare steel, so touch it up with a zinc-rich cold galvanizing compound if the walkway sees any moisture.
