B-Line 32012 12 GL Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 12 gauge steel

The 32012 12 GL plank is listed as OSHA compliant and is a three diamond serrated surface intended for safe, sturdy footing where non-slip is required. The diamond openings shed liquids, oil and debris rather than holding them on the surface, which is why it gets used on platforms, catwalks and stair treads in plants and mechanical rooms.

Mill-galvanized steel is the standard indoor and sheltered-outdoor finish. The zinc coating is applied to the coil before forming, so the cut ends and pierced diamond edges are bare steel and will show surface rust in constant wetting, chemical washdown or coastal exposure. For damp interiors, mechanical rooms, pump houses and covered platforms it's fine. For continuous immersion, washdown or corrosive process areas, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

This plank is formed from 12 gauge steel with a 2 inch channel depth. Gauge sets the metal thickness and the channel depth sets the span capability: 2 inch is the shallow, shorter-span profile used over closely spaced supports. If your support beams are spaced further apart or you're carrying heavy rolling loads, move up to a deeper channel plank rather than trying to stretch the 2 inch section.

The 32012 12 GL is the plank only, 144 inches of 7 inch wide 12 gauge mill-galvanized Grip Strut. Attachment hardware, hold-down clips, saddle clips or self-drilling screws are ordered separately, and you'll want the fasteners to match the mill-galvanized finish so you aren't mixing metals on a walkway.

No, it's different. Grip Strut is a single-piece formed steel plank with pierced, serrated diamond openings, 7 inches wide with a 2 inch channel on this model, and it drops in as a plank on supports. Bar grating is a welded assembly of bearing bars and cross rods, usually heavier and used where you need long spans or high wheel loads. For maintenance catwalks, ladder platforms and stair treads where slip resistance and light handling weight matter more than span, the formed plank is the usual choice.

Order Eaton B-Line part number 32012 12 GL. That designation covers the three diamond plank at 144 inch length, 7 inch width, 2 inch channel, 12 gauge steel, mill-galvanized. Width, gauge and finish are all baked into the number, so there are no separate options to call out.

Yes, the steel plank can be field cut to length with an abrasive saw or bandsaw. Because the galvanizing is mill applied and not dipped after forming, the fresh cut edge is bare steel, so touch it up with a zinc-rich cold galvanizing compound if the walkway sees any moisture. Ordering full 144 inch lengths and cutting on site is common practice for platform infill.
