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.

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.

Stair Tread Covers
Protect stairs from wear or provide a new stair surface on worn stairs. Covers fit square-nose concrete and wood stairs.
Styles A and B are oil- and chemical-resistant vinyl. To install, use construction adhesive (sold separately).
Styles C-F are durable rubber for high-traffic areas. To install, use construction adhesive (sold separately). Style F have abrasive strips for added traction.
Style G are corrosion-resistant aluminum with a grit top for excellent traction in high-traffic areas. Covers have 1/4" diameter countersunk mounting holes. To install, use construction adhesive (sold separately), or screw in place; use concrete screws or #10 wood screws.
Style H are fiberglass with a grit top for superior corrosion resistance in harsh environments and excellent traction in high-traffic areas. Covers have glow-in-the-dark nosing for high visibility. To install, use construction adhesive (sold separately), then drill and screw in place; use stainless steel truss-head screws.
