FRP (Fiberglass Reinforced Plastic) Stair Tread Covers are high-performance safety solutions designed to provide slip resistance, structural reinforcement, and extended durability to existing stairways. These covers are typically installed over worn or slippery stairs made from concrete, wood, or metal, making them ideal for both retrofit and new construction projects across various industrial, commercial, and even public access environments.

Manufactured using a combination of fiberglass reinforcements and thermosetting resin systems—such as isophthalic polyester, vinyl ester, or phenolic resin—FRP stair tread covers are engineered to withstand harsh environmental conditions, heavy pedestrian traffic, and chemical exposure. The result is a long-lasting, corrosion-resistant stair safety product that significantly reduces the risk of slips and falls.

One of the key features of FRP stair tread covers is their anti-slip surface. Most covers come with a highly abrasive grit surface made from fused aluminum oxide or silica quartz particles, permanently bonded to the top layer. This grit provides exceptional traction in wet, oily, or icy conditions and complies with OSHA and ADA safety standards. The covers are also available with high-visibility contrasting nosings, typically in yellow or other bright colors, which improve visibility and promote safe step identification.

FRP stair tread covers are lightweight yet extremely strong. They are easy to install using mechanical fasteners or adhesives, and require minimal maintenance throughout their lifespan. Their non-conductive and non-sparking properties also make them suitable for use in electrical facilities and explosive environments. Furthermore, many versions are fire-retardant and UV-resistant, making them a reliable option for both indoor and outdoor applications.

Typical applications for FRP stair tread covers include manufacturing plants, food processing facilities, oil and gas platforms, marine docks, transportation terminals, schools, hospitals, warehouses, and parking structures. In locations where stairs are frequently exposed to moisture, grease, or chemical spills, these covers provide a highly effective and durable safety upgrade.

Specifiche tecniche vary depending on the manufacturer, but standard FRP stair tread covers are available in thicknesses of 3 mm to 5 mm (1/8" to 3/16") and typically come in standard widths of 70 mm to 300 mm (2.75" to 12") with depths covering up to 1200 mm (4 feet). Custom sizes are also available to fit non-standard staircases. The stair tread nosing is often molded or applied as an integrated part of the cover to resist peeling or detachment over time.

Additionally, FRP stair tread covers support sustainability goals as they often outlast traditional materials, reducing the need for frequent replacements. Their installation minimizes downtime and enhances safety immediately upon placement, making them a cost-effective solution for facilities aiming to meet health and safety compliance with minimal disruption.
