Did you know

Many stair-related accidents occur because the leading edge of a step becomes smooth or slippery over time. Installing anti-slip stair nosings creates a high-grip walking surface where it's needed most, helping to improve safety while also protecting the edge of the step from wear and damage. 

The performance of any anti-slip stair nosing starts with the material it's made from. That's why our stair nosings are manufactured from Glass Reinforced Polyester (GRP), a high-performance composite material renowned for its exceptional strength, durability and resistance to the elements. GRP is widely used in demanding industries such as construction, transport, marine and manufacturing, where materials are expected to withstand heavy use and challenging conditions over many years. 

Unlike traditional materials, GRP combines the strength of glass fibres with a durable polyester resin to create a product that is both lightweight and incredibly tough. This unique combination allows our Anti-Slip GRP Stair Nosings to cope with constant foot traffic, impacts and changing weather conditions without losing their structural integrity or anti-slip performance. 

One of the biggest advantages of GRP is its resistance to corrosion. Metal stair nosings can rust over time, particularly in outdoor or damp environments, while timber can absorb moisture, rot or warp. GRP is unaffected by these issues, making it an excellent long-term solution for both internal and external staircases. It's also resistant to UV exposure, many chemicals and temperatures ranging from -50°C to +110°C, ensuring reliable performance throughout the year. 

The gritted anti-slip surface is permanently bonded to the GRP base during manufacture, creating a robust finish that's designed to withstand heavy pedestrian traffic without peeling or delaminating under normal use. This makes GRP stair nosings a dependable choice for busy commercial buildings, industrial sites, schools, hospitals and public spaces where safety and durability are essential. 

Although incredibly strong, GRP is also surprisingly lightweight. This makes the stair nosings easier to transport, handle and install than many traditional alternatives, helping to reduce installation time while still providing long-lasting protection for the leading edge of every step. 

Why Choose GRP? 

• Won't rust or corrode, making it ideal for damp or outdoor environments.  
• Will not rot or warp, unlike timber stair edging.  
• Excellent resistance to chemicals, UV exposure and harsh weather conditions.  
• High strength-to-weight ratio, making installation easier without compromising durability.  
• Designed for long-term performance in busy commercial, industrial and public environments.  
• Low maintenance, requiring only routine cleaning to keep the anti-slip surface performing at its best.

Good to Know

If you're ordering stair nosings for an existing staircase, it's always worth measuring each step individually rather than assuming they're all identical. On older staircases, slight variations in width are quite common. Taking accurate measurements helps ensure the best possible fit, particularly when ordering bespoke cut lengths. 

From the Mats4U Team 

One of the biggest advantages of these GRP Stair Nosings is how adaptable they are. Many customers are replacing worn or damaged stair edging on existing staircases rather than installing completely new stairs. Choosing pre-drilled stair nosings and measuring each step carefully before ordering can make installation quicker and help achieve a cleaner, more professional finish.

Not every staircase is located inside a clean, dry building. Many are exposed to rain, frost, direct sunlight, chemicals, heavy foot traffic or demanding industrial conditions every day. That's why our Anti-Slip GRP Stair Nosings are designed to deliver reliable performance in a wide variety of environments, helping to maintain both safety and durability throughout the year. 

Manufactured from high-quality Glass Reinforced Polyester (GRP), these stair nosings are naturally resistant to many of the conditions that can shorten the lifespan of traditional stair edging. Unlike untreated metal, they won't rust or corrode, and unlike timber, they won't rot, warp or absorb moisture. This makes them an excellent choice for both internal and external staircases where long-term performance is essential. 

The robust construction is also resistant to UV exposure, helping to maintain its strength and performance even when installed in outdoor locations exposed to direct sunlight. Whether fitted to an external fire escape, loading bay steps or an entrance staircase, you can rely on GRP to provide dependable protection in all seasons.

By combining excellent slip resistance with outstanding durability, these stair nosings provide a long-lasting solution that's designed to continue performing even in demanding environments. 

Things to Consider

While GRP is highly resistant to weather, chemicals and everyday wear, choosing the correct fixing method is just as important as choosing the right stair nosing. The type of staircase you're fitting to—whether concrete, timber or metal—may determine whether screws, adhesive or a combination of both provides the most secure installation. 

From the Mats4U Team 

Customers often ask us whether GRP stair nosings are suitable for outdoor use all year round. The answer is yes. They're specifically designed to cope with the changing British climate, from freezing winter mornings to hot summer days. As with any external safety product, regular cleaning to remove mud, leaves and other debris will help keep the anti-slip surface performing at its best, but the GRP itself is built to withstand the elements for years to come.

One of the advantages of Anti-Slip GRP Stair Nosings is that they require very little maintenance to keep them performing at their best. Thanks to their durable Glass Reinforced Polyester (GRP) construction and hard-wearing resin-bonded grit surface, they are designed to withstand everyday use without the need for specialist treatments or regular repairs. 

Like any anti-slip surface, stair nosings perform most effectively when they're kept free from excessive dirt, mud, leaves and other debris. Regular cleaning helps maintain the textured surface, ensuring it continues to provide excellent grip while also keeping your staircase looking clean and professional. 

For most installations, a quick sweep with a stiff brush is all that's needed to remove loose dirt and debris. If a deeper clean is required, simply wash the stair nosings with warm water and a mild detergent. In outdoor environments or areas exposed to heavier soiling, a low-pressure pressure washer can also be used to remove stubborn dirt without damaging the anti-slip surface. 

Unlike painted or coated alternatives, the anti-slip surface is designed for long-term durability, meaning there's no need for regular repainting or refinishing as part of normal maintenance. 

Cleaning Recommendations 

• To help keep your Anti-Slip GRP Stair Nosings in excellent condition, we recommend: 
• Sweeping regularly to remove loose dirt and debris.  
• Cleaning with warm water and a mild detergent when required.  
• Using a stiff brush for stubborn dirt or ingrained debris.  
• Using a low-pressure pressure washer for outdoor installations if necessary.  
• Inspecting the stair nosings periodically to ensure they remain securely fixed and free from damage.  

With just a small amount of routine maintenance, your GRP stair nosings will continue to provide reliable slip resistance and help protect your staircase for many years. 

Top Tip

The anti-slip grit provides the best performance when it's clean and free from build-up. In outdoor areas, removing leaves, moss and compacted dirt as part of your regular maintenance routine will help ensure the surface continues to provide maximum grip throughout the year. 

From the Mats4U Team 

One question we occasionally receive is whether harsh cleaning chemicals are needed to maintain GRP stair nosings. In most cases, they aren't. For everyday cleaning, warm water, a mild detergent and a stiff brush are usually all that's required. Keeping the surface clean with regular, simple maintenance is often far more effective than occasional deep cleaning, especially on busy staircases that are used every day.
