🧠FAQ's

What are GRP stair treads?

GRP stair treads are pre-formed anti-slip step covers made from glass reinforced plastic. They are designed to fit over existing stair surfaces to improve grip, highlight step edges, and reduce the risk of slips and trips in commercial, industrial, and public environments.

Are GRP stair treads suitable for outdoor use?

Yes, GRP stair treads are suitable for both internal and external use. They are highly durable and perform well in wet, cold, and high-traffic environments, making them ideal for outdoor steps, fire escapes, access stairs, and service areas.

How are GRP stair treads installed?

GRP stair treads are typically installed onto existing concrete, steel, or timber steps using mechanical fixings, adhesive, or a combination of both depending on the surface and environment. Correct installation helps ensure a secure fit and long-lasting performance.

What are the benefits of anti-slip GRP stair treads?

Anti-slip GRP stair treads help improve safety by providing a hard-wearing, slip-resistant surface with a visible nosing edge. They are resistant to corrosion, weathering, and heavy wear, and they offer a fast, cost-effective way to upgrade unsafe stairs without fully replacing them.

Can GRP stair treads be cut to size?

Yes, GRP stair treads can often be supplied in standard sizes or cut to size to suit your staircase requirements. This makes them suitable for a wide range of step widths and applications.

Where are GRP stair treads commonly used?

They are commonly used in factories, warehouses, schools, public buildings, plant rooms, external staircases, fire escapes, and other areas where extra slip resistance and step visibility are important.

Are GRP stair treads suitable for fire escapes?

Yes. GRP stair treads are commonly installed on external fire escape staircases due to their excellent slip resistance and durability. They provide enhanced grip in wet, icy and contaminated conditions, helping to improve safety for staff and visitors.

Can GRP stair treads be installed onto concrete steps?

Yes. GRP stair treads can be installed onto concrete, steel, timber and other solid stair substrates. Depending on the application, they can be fixed using mechanical fixings, adhesive, or a combination of both for maximum security.

What fixings should I use for GRP stair treads?

The most suitable fixing method depends on the stair substrate. Stainless steel screws or bolts are commonly used for timber and steel stairs, while concrete stairs may require masonry fixings. For some installations, a specialist adhesive can also be used to provide additional support.

Do I need a contrasting nosing on my stairs?

In many commercial and public environments, a contrasting stair nosing is recommended to improve visibility and help users identify the edge of each step. Our GRP stair treads are available in high-visibility colour options, including Black/Yellow and Black/White, to assist with step edge recognition.

Are GRP stair treads DDA compliant?

GRP stair treads can help support compliance with accessibility and safety requirements by improving slip resistance and increasing step edge visibility. However, overall compliance depends on the specific staircase design and installation. We recommend checking your project requirements or contacting our team for guidance.

Bonus FAQ (worth adding)
