B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Aluminum, 2" Channel size, Grip Strut, .100" Thick

Yes. The B-Line Eaton Grip Strut four diamond plank is listed as OSHA compliant, and the four diamond perforated surface is what does the work: the raised diamond openings shed water, oil, mud and light snow and give traction in every direction. It is the surface you use where non-slip footing is required on catwalks, stair treads, mezzanines and equipment platforms.

This plank is aluminum, which is the version to pick for exposed outdoor runs, coastal sites, wastewater and washdown areas, and food or chemical plants where galvanized or painted steel will eventually corrode at cut edges. Aluminum is also the choice when crews have to carry and set planks by hand. Steel Grip Strut is the alternative where you need higher load capacity per span or where the plank will take impact and abrasion from equipment traffic.

It is formed from .100 inch aluminum, called out as 12 gauge. That thickness is what sets the span you can run between supports, so the closer you set your support spacing, the more load the plank carries. Check the gauge against the plank you are replacing before ordering, because Grip Strut is made in several thicknesses and a lighter one will feel springy underfoot on a long span.

The plank has a 2 inch deep channel on each side, so it seats down over your supports with the walking surface 2 inches above the top of the supporting member. Set your beam or angle spacing so each plank end lands on steel, and account for that 2 inch buildup where the walkway meets a stair tread, a doorway threshold or an adjacent grating run, or you will create a trip edge.

Aluminum Grip Strut cuts cleanly on the job with a circular saw and a non-ferrous blade, so a 120 inch plank can be trimmed to fit a shorter bay or notched around a column. Cut aluminum does not need the field touch-up that a cut galvanized steel plank does, which is part of why it gets specified for retrofit runs where nothing measures out to full lengths.
