B-Line Eaton series Grip Strut ten diamond plank, 120" Grating length, 24" Grating width, Steel, 4.5" Channel size, Galvanized, Grip Strut, 12 gauge

Yes. The ten diamond Grip Strut plank is listed as OSHA compliant, and the diamond-perforated surface is the non-slip type used where safe footing is required on catwalks, platforms and stair landings.

The plank is 12 gauge steel with a mill-galvanized finish, which is the standard choice for outdoor platforms, utility yards and damp mechanical spaces. Note that mill-galvanized means the sheet was coated before forming, so cut and sheared edges are bare steel; for a highly corrosive or coastal environment, specify a hot-dip galvanized or stainless plank instead.

Listed weight is 12.5 lb, so a single 10 foot plank is a one or two man carry up a ladder or scaffold, unlike bar grating panels of the same footprint. Handy when you are decking out a long cable tray catwalk piece by piece.

The 4.5 inch figure is the formed channel depth of the plank, which is also its overall height. Allow for that depth when you set support beam elevations so the finished walking surface lands at the height on the drawing, and remember the plank spans between supports on its own legs rather than sitting flat like flooring.

No. Diamond count refers to how many rows of diamond perforations run across the width, which sets the walking width. Ten diamond gives the 24 inch wide plank used for platforms and catwalks; two, three and four diamond widths are the narrow treads used for stair steps and ladder rungs. If you are decking stair treads, order the narrow tread, not this plank.
