About Stair Tread Covers and Nosing
More
Metal Bar Grating Stair Treads
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 treads are for use in dry, noncorrosive areas.
Galvanized steel treads are more corrosion resistant than painted steel.
Aluminum treads are more corrosion resistant than galvanized steel. Plus, they're lightweight, nonsparking, and nonmagnetic.
Stainless steel treads have better corrosion resistance than steel or aluminum.

Metal Plank Grating Stair Treads
The most economical stair treads we offer.
Stair treads with projections provide good slip resistance that's more comfortable than serrated.
Serrated stair treads provide maximum slip resistance.
Powder-coated steel treads are for use in dry, noncorrosive areas.
Galvanized steel treads are more corrosion resistant than powder-coated steel.
