B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 2.5" Channel size, Plain, Grip Strut, 14 gauge

Yes. The eight diamond Grip Strut plank is listed as OSHA compliant and is made for safe, sturdy footing where non-slip walking surface is required, which is the usual call-out on mezzanines, catwalks, equipment platforms and rooftop access runs.

It is plain steel, 14 gauge, with no finish applied. Plain means bare mill steel, so outdoors or in a wash-down or corrosive area it will need paint, galvanizing or another coating. If the plank is going in a damp or exterior location and you do not want to coat it in the field, specify a pre-galvanized version instead.

Eight diamond refers to the number of diamond openings across the width of the plank, and here that works out to an 18.75 inch wide walking surface. More diamonds across means a wider single piece, so you need fewer planks side by side to make up a given platform width. The pierced-and-formed diamonds are what give the surface its grip in all directions.

It does. The 2.5 inch channel is the formed side rail depth, and that depth is what carries the plank between supports, so a deeper channel spans farther than a shallow one at the same gauge. This plank is 14 gauge steel with a 2.5 inch channel. Set your support spacing from the span and load table for that channel size and gauge for the loading you are designing to.

No fasteners are included. The plank ships as the formed steel walking surface only, so plan on hold-down clips, bolts or welding to your steel supports as a separate line item on the order.

Order as Eaton B-Line model 82514 12 BL. The listed product weight is 6.6 lb, which is worth knowing when you are hand-carrying 12 foot pieces up to a mezzanine or roof rather than craning them.
