B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 10

The B-Line Grip Strut plank is listed as OSHA compliant. It is a serrated-diamond, non-slip surface intended for safe, sturdy footing where slip resistance is required, which is why it shows up on platforms, stair treads runs, catwalks and equipment access walkways in industrial and institutional facilities.

This plank is 10 gauge steel with a mill-galvanized finish. Mill galvanizing is applied to the coil before forming, so the cut edges and punched openings are bare steel. That is fine for covered, dry, or normal industrial interiors, and it is the usual choice for indoor mechanical and electrical platforms. For constant moisture, chemical exposure, or full outdoor weather, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

Each 144 inch plank weighs 19.9 lb. That is a one-man carry up a ladder or through a hatch, and it is light enough that a crew can set a long platform run without rigging. Use that figure for dead load when you are tallying a catwalk deck.

Diamond count is how Grip Strut widths are described: more diamonds across, wider the walking surface. The eight diamond version measures 18.75 inches wide, which is a full walkway or platform deck. Narrower two, three, or four diamond planks are what you use for stair treads, ladder rungs, and single-file access. If you are decking a mechanical platform or a cable tray catwalk, the eight diamond is the piece you want; for stair treads, order the narrower profile.

This plank is formed from 10 gauge steel, which is the heavier of the common Grip Strut gauges and the usual pick for regular foot traffic on platforms, catwalks, and maintenance access decking. Lighter gauges are used where traffic is occasional. Span capacity still depends on how far apart your supports sit, so set your support spacing from the load you need to carry rather than gauge alone.

Yes, the 144 inch steel plank can be cut down on site to fit a shorter bay or work around a penetration. Cutting exposes bare steel at the new edge, since the mill-galvanized coating is applied to the coil before forming, so touch up field cuts with a cold galvanizing compound if the platform sees any moisture.
