Metal Bar Grating Stair Treads


Smooth Powder-Coated Steel	Smooth Galvanized Steel	Smooth Aluminum	Smooth 304 Stainless Steel

Serrated Powder-Coated Steel	Serrated Galvanized Steel	Serrated Aluminum	Mounting Dimensions

Choose these stair treads for greater durability than metal plank grating stair treads. They have an open surface that prevents debris from accumulating. Nosing is textured for traction.

Powder-Coated Steel—Powder-coated steel treads are for use in dry, noncorrosive areas.

Galvanized Steel—Galvanized steel treads are more corrosion resistant than painted steel.

Aluminum—Aluminum treads are more corrosion resistant than galvanized steel. Plus, they're lightweight, nonsparking, and nonmagnetic.

304 Stainless Steel—Stainless steel treads have better corrosion resistance than steel or aluminum.

Fiberglass Stair Treads

These lightweight fiberglass treads are corrosion resistant, nonconductive, and nonmagnetic. The surface is grit coated for traction. Cut treads with a circular saw using a diamond-grit blade, and seal the cut end with an epoxy sealant (sold separately). Use Fasteners for Fiberglass Bar Grating to secure.
