B-Line Eaton series Grip Strut two diamond plank, 120" Grating length, 4.75" Grating width, Aluminum, 2.5" Channel size, Grip Strut, .100" Thick

Each Grip Strut plank runs 120 inches long by 4.75 inches wide, with a 2.5 inch channel height. That narrow 4.75 inch width means walkways, catwalks or stair landings wider than that get made up by running planks side by side across the supports. The 2.5 inch channel depth is what you need to allow for in your framing height.

The Grip Strut two diamond plank is listed as OSHA compliant, and the diamond-pierced surface is intended for safe, sturdy footing where non-slip is required. That is the reason it gets specified for elevated platforms, mezzanine walkways and stair treads in plants and mechanical rooms.

This plank is aluminum, so it will not rust the way a plain painted steel plank does, which is why it gets used on wash-down floors, coastal sites, water treatment platforms and rooftop equipment access. Aluminum also keeps the plank light enough for one person to place a 10 foot length. If you need higher load capacity over long spans, steel or galvanized Grip Strut is the heavier-duty option.

Model 22510 10 AL is formed from 12 gauge aluminum at .100 inch thick. That gauge is what carries the walking load between supports, so when you lay out your support spacing, size it for 12 gauge aluminum rather than assuming steel-equivalent spans.

Order it as Eaton B-Line series part number 22510 10 AL. That number covers the two diamond plank in aluminum, 120 inch length, 4.75 inch width, 2.5 inch channel, .100 inch thick. Distributors cross-referencing should note the 10 in the number corresponds to the 10 foot length.

The 22510 10 AL is the plank only. Fasteners, hold-down clips, end plates and the supporting framing are separate items. The plank's 2.5 inch channel legs are what you clamp or bolt through to the support member, so pick hold-downs suited to your support flange and keep the aluminum plank isolated from dissimilar metals where corrosion is a concern.

The diamond count is simply how many rows of pierced diamonds run across the width, so it tracks the plank width. This two diamond version is 4.75 inches wide, which suits stair treads and narrow catwalk runs, or gets ganged to build up a wider platform. A four or five diamond plank covers more width per piece and means fewer hold-downs on a broad walkway. The non-slip surface and OSHA compliance are the same either way.

Yes. It ships as a 120 inch length and is routinely cut down in the field to suit the opening, which is far easier in aluminum than in galvanized steel. Cut ends should be deburred, since the diamond piercings leave sharp edges on a walking surface.
