B-Line Eaton series Grip Strut two diamond plank, 144" Grating length, 4.75" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 14

Yes. The Grip Strut two diamond plank is listed as OSHA compliant, and it is made for safe, sturdy footing where a non-slip surface is required. The pierced diamond openings shed water, oil and debris and give traction in more than one direction of travel, which is why it gets used on catwalks, mechanical platforms, stair treads and equipment access walkways. For a facility or MRO spec that calls out a slip resistant open surface, this meets that intent.

If the run you are replacing is the two diamond, 4.75 inch wide, 1.5 inch channel profile in 14 gauge, this drops into the same supports, since the channel depth and width set the bearing. Order by the B-Line number 21514 12 GL and confirm your existing section's width and channel depth before pulling the damaged plank. If the old material is a wider multi-diamond section or a deeper channel, the new piece will not sit flush on the same framing.

Mill-galvanized is the finish here, meaning the steel was galvanized before forming, so the cut ends and the pierced diamond edges are bare steel. That is fine for dry interior plant, mechanical room and covered platform work, and it handles occasional moisture. For constant wet exposure, wash-down, coastal air or corrosive process areas, specify hot-dip galvanized after fabrication or stainless instead, since those protect the cut edges too.

No. What you get is the plank itself: one 144 inch, 14 gauge steel, mill-galvanized two diamond section. Hold-down clips, bolts, saddle washers and any support framing or channel the plank sits on are ordered separately. Plan your supports so the 1.5 inch deep channel legs bear on the framing at the spacing your load calls for.

The diamond count tells you how many rows of the raised, pierced diamond pattern run across the width, which is really a width call. This two diamond plank is 4.75 inches wide, so it suits stair treads, narrow ledge walkways, pipe crossovers and single-plank access runs. When you need a full platform or a two-way walkway, you either gang several of these side by side on common supports or step up to a wider multi-diamond section. The surface, the 14 gauge steel and the 1.5 inch channel depth are the same either way.
