B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 2" Channel size, Mill-galvanized, 14 gauge

Each Grip Strut five diamond plank runs 120 inches long by 11.75 inches wide, so a single plank covers a 10 foot run in one piece with no field splice. Walkway width is fixed at 11.75 inches per plank, so wider platforms are built by laying planks side by side.

Yes. The five diamond Grip Strut plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is the usual reason it gets specified for catwalks, mezzanine crossovers, and equipment access platforms.

The plank has a 2 inch channel, and overall product height is 2 inches. That means the downturned side channels drop 2 inches below the walking surface, so allow 2 inches of clearance over any support member, conduit, or pipe running beneath the run.

It is formed from 14 gauge steel. That is the heavier of the common Grip Strut gauges, and it is what carries the load in a plank this wide with the 2 inch channel legs providing the stiffness.

The finish here is mill-galvanized steel, which is a pre-galvanized coating applied to the sheet before forming. It handles normal indoor industrial exposure and sheltered outdoor use. Cut and formed edges are left bare by mill-galvanizing, so for constant wet, coastal, or chemical wash-down service specify a hot-dip galvanized after fabrication or stainless plank instead.

A single plank weighs 4.4 lb, so a 10 foot section is a one-man carry up a ladder or through a hatch. That matters on retrofit work in existing plant where you cannot get a lift to the platform.
