B-Line MG61518FM 12 Eaton series Grate-Lock traction grip female to male interlock, 144" Grating length, 6" Grating width, Carbon steel, 1.5" Channel size, Mill-galvanized, Traction grip, Female/Male, 18 gauge

The MG61518FM 12 has a female edge on one side and a male edge on the other, so each plank locks into the next one across the run without separate connecting hardware. It's the standard field plank for building out a continuous deck. Plank runs are usually finished at the outside edges with the matching end profiles rather than a second female/male piece.

Mill-galvanized carbon steel is a light zinc coating suited to covered, indoor, and mildly damp industrial locations. For constant weather exposure, coastal air, or corrosive wash-down areas, a heavier hot-dip galvanized or stainless walkway product is the better call.

Yes. The MG61518FM 12 is the traction grip surface, punched for grip and specified for safe, sturdy footing where non-slip is required. That's the version to use on stair treads, catwalks, and platforms where oil or water gets tracked.

Match on four things: the 1.5 inch channel size, 6 inch width, 18 gauge material, and the traction grip surface. Mixing channel depths in one run leaves the interlocks sitting at different heights. The MG61518FM 12 is the 12 foot female/male field plank in that configuration.

Listed weight is 1.9 lb, so 18 gauge carbon steel planks in this size are a one-man carry up a ladder or onto a mezzanine, which is the main reason crews use interlocking planking instead of welded bar grating on retrofits.

The planks ship at 144 inches and are 18 gauge carbon steel, so they cut to length on site with a chop saw or shear. Cut ends lose the mill-galvanized coating, so hit them with a cold galvanizing compound before installing.
