B-Line 104512 10 GL P3 Eaton series Grip Strut ten diamond plank, 120" Grating length, 24" Grating width, Steel, 4.5" Channel size, Mill-galvanized, Grip Strut, 12 gauge

Yes. The 104512 10 GL P3 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 rooftop and mechanical-room walkways, platforms and catwalks. The diamond openings shed water, oil and debris instead of holding it on the tread surface.

Mill-galvanized is the finish on this 12 gauge steel plank. It is a pre-galvanized (galvanized-before-forming) coating, so the sheared edges and punched diamond openings are bare steel and will show surface rust in a genuinely wet, washdown or coastal environment. For covered indoor platforms, mechanical rooms and normal rooftop exposure it is the standard choice. If the location is continuously wet or chemically aggressive, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

Yes. What ships under 104512 10 GL P3 is the plank itself, 120 by 24 inches in 12 gauge steel. Framing, support angle or channel, and the hold-down clips or fasteners that tie the plank to the structure are all separate line items. Plan your support spacing first, because the 4.5 inch channel depth is what carries the span between supports.

It describes the tread pattern across the 24 inch width: ten rows of the pierced, raised-edge diamond openings. More diamonds across the sheet means more gripping edges underfoot and a wider walking surface, which is why the 24 inch wide ten diamond plank gets used for platforms and walkways rather than the narrower two or three diamond planks used as single stair treads.

The plank comes as a 120 inch length, and it is steel, so it is cut in the field with an abrasive saw or plasma the way any galvanized channel section is. Expect bare steel at the cut, since the mill-galvanized coating is applied to the sheet before forming, so cold-galvanizing spray on cut ends is normal practice on outdoor runs.

Order it as B-Line 104512 10 GL P3. That is the Eaton B-Line series catalog number for the 10 diamond, 120 inch by 24 inch, 4.5 inch channel, 12 gauge mill-galvanized Grip Strut plank.
