B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 12 gau

It's a three diamond Grip Strut plank measuring 144 inches long by 7 inches wide, with a 3 inch channel height, and it weighs 5.2 lb. That 12 foot length and light weight means one person can generally handle a plank up a ladder or into a rack, unlike bar grating panels of the same span.

Yes. The 33012 12 GL three diamond plank is listed as OSHA Compliant and is intended for safe, sturdy footing where non-slip is required, which is what facility and plant maintenance buyers are usually specifying it for on catwalks, mezzanine walkways, and equipment platforms.

No. Model 33012 12 GL is the plank only. Mounting hardware such as hold-down clips, saddle washers, or bolts for fixing the 3 inch channel legs down to your beams or angle supports is ordered separately, so add it to the same order if you are fabricating a walkway from scratch.

The 33012 12 GL is steel with a mill-galvanized finish, meaning the zinc coating is applied to the coil before the plank is formed. That suits dry interior plants, covered platforms, and light weather exposure. Cut ends and pierced diamond edges are bare steel after forming, so for constant wet, coastal, or wash-down duty you want a hot-dip galvanized or stainless plank instead.

12 gauge is the steel thickness of the formed plank, the heavier end of the common Grip Strut range. Paired with the 3 inch channel depth it is the choice for pedestrian walkways and platforms carrying foot traffic and carried tools. Lighter 14 or 16 gauge plank is used for shorter spans and lighter duty; going heavier or shortening support spacing is how you handle rolling loads.

The diamond count is the number of rows of pierced, serrated diamond openings across the width of the plank, which is what sets its width. This one is a three diamond plank at 7 inches wide. Two diamond plank is narrower for stair treads and tight runs; wider counts cover more walkway per piece. The traction surface itself is the same on all of them.

Order Eaton B-Line model 33012 12 GL. That covers the three diamond plank at 144 inch grating length, 7 inch grating width, 3 inch channel, 12 gauge steel in mill-galvanized finish.

Yes, the 12 gauge steel plank can be cut down from its 144 inch length on site with a chop saw or band saw to suit your support spacing. Expect bare steel at the cut, since the mill-galvanized coating is on the coil rather than applied after fabrication, so field cuts should get a cold galvanizing touch-up in any damp location.
