non-slip stair treads exterior

Exterior non-slip stair treads are commonly made from polyester, rubber, and recycled PET (polyethylene terephthalate).

Many exterior stair treads advertise weather-resistant or waterproof surfaces and resistance to mildew, stains, and fading. Designs are commonly intended to withstand rain, sleet, snow, heat, and general moisture exposure.

Traction comes from textured rubber surfaces and coarse coatings; some treads use industrial-grade abrasives—such as 80-grit aluminum oxide—as a slip-resistant top layer.

Care varies by material: polyester treads often list machine washing, rubber treads are typically cleaned by hosing off with water, and recycled-PET options may be spot-cleaned, hosed, or machine washed depending on the product.

Common pack sizes shown include larger sets such as 12-packs and smaller multi-packs like 2- or 4-count options.

Some exterior treads include visibility features such as glow-in-the-dark strips or reflective/luminous stripes to improve nighttime visibility.
