B-Line Eaton series Grip Strut ten diamond plank, 144" Grating length, 24" Grating width, Steel, 4.5" Channel size, Mill-galvanized, Grip Strut, 14 ga

The plank runs 144 inches long by 24 inches wide, so one piece spans a 12-foot run in a single length with a 2-foot walking width. The 4.5 inch channel size is the depth of the formed side channels, which is also the overall height of the plank when it is sitting on its supports. Plan your support spacing off the 144 inch length rather than cutting the plank down.

Yes. The 10-diamond Grip Strut plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required, which is the usual reason it gets specified for catwalks, mezzanine walkways, platforms and stair landings around electrical and mechanical equipment.

Mill-galvanized is the finish here, meaning the steel was galvanized before forming, so the cut edges and pierced diamond openings are left bare. It handles normally damp indoor and sheltered industrial locations. For continuously wet, washdown or coastal exposure, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

It is 14 gauge steel with a stated product weight of 8.9 lb. Two workers can set a 12-foot length by hand without lifting equipment, which is the main reason crews choose formed plank over bar grating for retrofit walkway work in occupied buildings.

The diamond count is how many rows of pierced, raised diamond openings run across the walking surface, so it sets the width. Ten diamonds gives the 24 inch width on this plank, wide enough for a full walkway or platform deck. The 2, 3 and 5 diamond planks are the narrow versions used for stair treads, single-file catwalks and ladder rungs. If you are decking a platform, order the 10 diamond; if you are covering stair treads, order the narrow plank.

No hardware is included. The 104514 12 GL is the bare 14 gauge steel plank only. You will need to order hold-down clips, saddle clips or bolts separately, and provide the supporting steel or channel framing the plank bears on.

The 4.5 inch formed side channels carry the load, so the plank spans between supports rather than needing continuous decking beneath it. It still has to bear on structural members at each end, and on intermediate supports for longer spans across the 144 inch length. Set the support spacing from your own load and deflection requirements for the platform.

Close, but not identical. Mill-galvanized steel weathers to a flat grey that reads slightly duller than hot-dip galvanized-after-fabrication grating, and the sheared edges and diamond piercings will be bare steel where hot-dip pieces are coated all over. For a visually consistent run on an existing hot-dip walkway, match the original finish rather than mixing the two.
