B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 12 gauge steel

Each plank of the Eaton B-Line Grip Strut three diamond plank runs 144 inches long by 7 inches wide, with a 2 inch channel depth. So a single piece gives you a 12 foot run of 7 inch wide tread. For wider walking surfaces, planks are laid side by side across the supports until you have the width you need.

The B-Line Grip Strut three diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required. The diamond openings are punched and formed so the edges bite into boot soles in oil, mud, ice or grease, which is the reason it gets specified for catwalks, platforms and mezzanine walkways.

Plain means bare, uncoated steel, not galvanized and not painted. It is the right choice for interior, dry locations, or where you intend to paint or coat it yourself after fabrication. For outdoor decks, wash-down areas or anywhere corrosion is a factor, order a galvanized version of the same three diamond plank instead.

The 2 inch figure is the depth of the formed channel, and it is also the overall height of the plank, so it sits 2 inches above the top of your supports. That channel depth is what carries the load between supports on a 12 gauge steel plank. Set your stringers or bearers to the span your load calls out, then run the 144 inch plank across them.

Yes. It is 12 gauge steel, so a plank can be cut down with a metal-cutting chop saw or bandsaw to suit the opening. Since the finish is plain, uncoated steel, any cut edge and the parent surface both want a field-applied coating if the location is at all damp.

The diamond count describes how many rows of punched diamond openings run across the width of the plank. This three diamond plank is 7 inches wide, which is the common single-tread and narrow-walkway width. Fewer diamonds means a narrower plank for stair treads and tight ledges; more diamonds means a wider plank that covers more deck with fewer pieces and fewer fasteners.

The 7 inch wide three diamond plank is a walking surface for platforms, catwalks and mezzanines where non-slip footing is required. Used on stairs, 7 inches is a narrow tread depth, so most stair applications take a wider plank or a purpose-made tread with a nosing and pre-punched end plates. Confirm the tread depth your stair drawing calls for before using this width on steps.

No mounting hardware is included with the B-Line Grip Strut plank itself. What you get is the 144 inch by 7 inch, 12 gauge steel plank. Plan on ordering hold-down clips, saddle clips or self-drilling fasteners separately to secure the channel legs to your bearers or stringers.

Order by the Eaton B-Line part number 32012 12 BL. That covers the three diamond plank, 12 gauge plain steel, 144 inch grating length, 7 inch grating width, 2 inch channel. Length, width, gauge and finish are all built into that single number, so there are no suffixes to add.
