B-Line Eaton series Grip Strut eight diamond plank, 120" Grating length, 18.75" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut,

Each Grip Strut plank runs 120 inches long by 18.75 inches wide, with a 2.5 inch channel depth at the sides. So one plank spans a 10 foot run and covers just over a foot and a half of walking width. For wider catwalks or platforms, planks are laid side by side to build out the width you need.

The Eaton B-Line Grip Strut eight diamond plank is OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required. The pierced diamond openings shed water, oil and debris and give grip from any direction of travel, which is why it gets used on catwalks, mezzanine walkways, stair treads and equipment platforms.

Mill-galvanized steel is the finish here, which is a zinc coating applied to the coil before forming. It handles normal indoor industrial exposure and sheltered outdoor use well. Because the plank is pierced and formed after galvanizing, the cut edges are bare steel, so in constant wet, coastal or chemical wash-down service you should expect edge rusting over time and look at a hot-dip galvanized or stainless plank instead.

A single 120 inch plank weighs 6.6 lb, so one worker can carry and place it without a lift. That light weight comes from the 14 gauge steel and the open diamond pattern, which also keeps dead load down on mezzanine and rooftop framing.

The diamond count is the width. This one carries eight rows of diamonds across, giving 18.75 inches of walking surface per piece. Narrower planks with fewer diamond rows are used for single stair treads or tight service aisles; the eight diamond size is the one people reach for when they want a full walkway width from one plank instead of seaming two together.

The plank is 14 gauge steel with 2.5 inch formed side channels, and those channels are what you fasten through. It sits on the top flange of your bearing members and is clamped or bolted down at each support. Hold-down clips, saddle clips and bolts are ordered separately from the plank itself, so size those to your support spacing and flange thickness.

Order Eaton B-Line part number 82514 10 GL. That number covers the eight diamond plank in 120 inch length, 18.75 inch width, 2.5 inch channel, 14 gauge steel, mill-galvanized finish.

Yes, the plank is 14 gauge steel and can be cut down on site to suit a shorter run or to notch around columns and pipe penetrations. Cut ends expose bare steel through the mill-galvanized coating, so touch them up with a cold galvanizing compound if the walkway sees moisture.
