Non-Slip Outdoor Stair Tread Covers 345mm x 55mm

If you're looking for an easy and effective way to improve the safety of your staircase, then our non-slip outdoor stair tread covers are the perfect solution. Made from GRP (glass reinforced plastic), these non-slip tread covers provide a textured surface that significantly increases grip and traction, even outdoors. This makes them ideal for businesses, schools and public places that want to reduce the risk of slips and falls, especially in wet or icy conditions.

Moreover, our non-slip outdoor stair tread covers comply with UK Building Regulations and the DDA (Disabled Discrimination Act), making them a great choice for commercial premises that need to meet strict safety standards.

Why our Non-Slip GRP Stair Treads are Better

Our GRP Stair Treads are made from moulded - not layered - GRP, which removes the risk of bubbling and delamination. These outdoor stair tread covers are second-to-none for slip resistance and are resistant to chemicals and fire, boasting extreme durability designed to last for years.

Where to use Non-Slip Outdoor Stair Tread Covers

The non-slip stair treads can be placed over the top of existing steps indoors and outdoors. The grip is provided by silicone carbide, which creates a coarse-textured surface that works in dry and wet conditions.

Unlike nosing, which only covers the edges of the steps, our outdoor stair treads also cover the entire step providing maximum grip coverage.
