B-Line 81514 12 GL Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 14 gauge steel

The 81514 12 GL plank runs 144 inches long and 18.75 inches wide, with a 1.5 inch channel depth. That is a 12 foot walking surface per piece, so for a platform or catwalk wider than 18.75 inches you set planks side by side. The 1.5 inch height is what you need to allow for in your support framing and finished walking elevation.

Eaton B-Line Grip Strut eight diamond plank is listed as OSHA compliant. The pierced diamond openings give a non-slip surface in the direction of travel, which is why it gets specified for catwalks, mezzanine walkways, stair treads and equipment access platforms where wet, oily or icy footing is a risk.

The 81514 12 GL is 14 gauge steel with a mill-galvanized finish. Mill galvanizing is applied to the coil before forming, so the cut edges and pierced diamond openings are raw steel and will show surface rust in standing water, washdown or coastal exposure. It is suited to covered outdoor and general industrial use. For continuous wet or corrosive service, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

Grip Strut is a one-piece formed steel plank with pierced diamond openings raised into a serrated gripping surface, so traction comes from the surface itself rather than from the edge of a bar. Bar grating is a welded assembly of load bars and is generally chosen for heavier rolling loads and longer spans. This 14 gauge, 1.5 inch deep, 6.1 lb plank is the lighter option, used for personnel access walkways, platforms and stair treads where slip resistance and low added weight matter more than heavy load capacity.

The Eaton B-Line part number is 81514 12 GL: eight diamond plank, 18.75 inch grating width, 144 inch length, 1.5 inch channel, 14 gauge steel, mill-galvanized. If your existing walkway uses a different plank width or channel depth, the profile will not sit flush alongside this one, so check the width and depth of what is already installed before standardizing on this number.

Yes. The plank is 14 gauge steel and cuts with a metal-cutting saw or shear to suit a run shorter than the 144 inch stock length. The cut end exposes bare steel because the mill-galvanized coating is applied before forming, so field-cut edges should be treated with a cold galvanizing compound if the walkway sees moisture.
