GRP vs. Traditional Safety Materials: Which Offers Better Longevity and Safety?

When it comes to keeping stairways, ramps, and walkways safe — especially in high-traffic or wet UK environments — the materials you choose matter more than ever. Whether you're responsible for a school, public building, industrial site, or commercial premises, selecting the right safety solution can drastically reduce slip risks, improve compliance, and save thousands in long-term maintenance. Two of the most commonly used safety materials in the UK today are GRP (Glass Reinforced Plastic) and traditional options like aluminium, steel, or PVC stair nosing. While traditional materials have been used for decades, modern GRP alternatives are increasingly preferred thanks to their outstanding durability, low maintenance needs, and slip resistance — even in the harshest British conditions.

At Commercial Nosing, we supply a wide range of both GRP and traditional safety solutions, including heavy-duty stair nosing covers, hazard strips, and anti-slip decking strips. This blog will explore the key differences between GRP and traditional safety materials, looking closely at longevity, slip resistance, UK compliance (like BS7976-2 and DDA regulations), and installation considerations. Whether you're upgrading a public stairwell or specifying materials for a new build, this guide will help you make a safer, smarter decision.

Material Breakdown: What Is GRP and How Does It Compare?

GRP Explained – The Modern Safety Material

GRP (Glass Reinforced Plastic) is a high-strength composite made from fine glass fibres and resin. Known for its durability, corrosion resistance, and anti-slip surface, it has become the go-to choice for UK stair safety, especially in outdoor, wet, or high-traffic environments. Unlike steel or wood, GRP won't rust, rot, or degrade in damp conditions — making it a powerful long-term investment. It's also incredibly lightweight, which means faster installation and less manual handling.

At Commercial Nosing, we offer several GRP options designed to meet different safety challenges:

• Heavy Duty 70mm x 55mm Stair Nosing Cover GRP Anti-Slip Solution
  Designed for high-traffic areas, this chamfered-edge nosing is corrosion-resistant, DDA & Building Regulation compliant, and can be fixed to most surfaces — including concrete, wood, and chequer plate.

• 55mm x 55mm Medium Grit GRP Stair Nosing Cover
  Perfect for general commercial use, this medium-grit option is wear-resistant, chemical-resistant, and suitable for wet, oily, or heavy-use areas.

• 90mm Anti Slip GRP Strips for Slippery Decking and Ramps
  These quartz-gritted strips provide extra grip where stairs or ramps become dangerously slick — ideal for schools, warehouses, and public areas.

Traditional Safety Materials: Still in Use, But Showing Their Age

While aluminium, PVC, and even wood are still used in some settings, they come with compromises. Steel rusts over time, especially in outdoor or coastal areas. PVC can crack or fade under UV exposure, and wood deteriorates rapidly in wet conditions — requiring regular maintenance.

Here are some of our traditional offerings:

• 60.4mm x 32mm PVC Hard Nose Non Slip Heavy Duty Stair Nosing
  Cost-effective with colour options, but requires dry, even installation surfaces and adhesive application.

• 60mm x 55mm Rakeback Aluminium Stair Nosing With Non Slip PVC Insert
  Robust and long-lasting with a grippy PVC insert — suitable for carpeted or dry commercial areas.

While traditional materials still have a place, GRP is rapidly becoming the first choice for UK businesses looking for long-term safety with minimal upkeep.

Comparison Table: GRP vs Traditional Safety Materials

When deciding between GRP and traditional materials like aluminium or PVC for stair safety, it’s helpful to see the facts side by side. Below is a detailed comparison based on key factors that matter in UK environments, including lifespan, safety, maintenance, and compliance.

As the table shows, GRP stair nosing offers clear advantages in safety, compliance, and lifecycle costs — particularly for projects where longevity and low maintenance are critical. While traditional options may still be suitable for indoor or decorative use, GRP remains the smarter investment for heavy-use environments.

Performance in UK Conditions: Longevity, Weather & Use

GRP: Designed for British Weather and Heavy Use

GRP is purpose-built to perform in the kinds of environments the UK is known for — coastal air, rainy walkways, icy steps, and high-footfall locations like schools, transport hubs, or warehouses.

• Corrosion-resistant: Unlike steel, GRP won’t rust — even in coastal or damp zones

• Rot-proof: Unlike timber, GRP doesn’t absorb water or decay over time

• UV stable: Resists fading and weakening, even under outdoor exposure

• Anti-slip in all weather: Gritted surfaces offer consistent grip in rain, frost or oil

Featured Product:
90mm Anti-Slip GRP Strips for Slippery Decking and Ramps
Tough quartz-grit strips designed for decking, ramps, or steps where safety must be maintained in wet, greasy, or icy conditions. Quick to install, easy to maintain, and highly durable. Explore the full GRP product range here:

Traditional Materials: Short-Term Gains, Long-Term Costs

Aluminium may look sleek, but it oxidises, becomes slippery when wet, and dents under load. PVC is more budget-friendly, but it cracks under UV exposure, may lose grip over time, and needs a perfectly flat, clean surface for proper adhesion.

 Example Product:
60.4mm x 32mm PVC Hard Nose Non Slip Heavy Duty Stair Nosing – effective in dry areas but requires careful prep and is less resilient in outdoor or damp conditions.

Slip Resistance: Staying Safe in Wet & High-Traffic Zones

Why GRP Outperforms in Anti-Slip Protection

GRP stair nosing and decking strips come with a coarse quartz grit surface that provides outstanding grip underfoot — even in wet, oily, or icy conditions. These products are tested to BS7976-2, the UK standard for slip resistance, and regularly achieve R13+ ratings.

Featured Product:
55mm x 55mm Medium Grit GRP Stair Nosing Cover
Offers Level 3 slip resistance (equivalent to R13), suitable for dry, wet, greasy, or high-traffic areas.

Also Recommended:
GRP Hazard Strips for Slippery Decking and Ramps
Compact, high-visibility hazard strips with a coarse anti-slip grit — ideal for outdoor walkways or shaded steps.

The Challenge with Traditional Materials

Aluminium may seem like a hard-wearing option, but it quickly becomes slippery when wet. PVC stair nosing products offer some grip via embedded strips, but the surface can wear down with regular use.

Example Traditional Product:
60mm x 55mm Rakeback Aluminium Stair Nosing With Non-Slip PVC Insert
Effective for indoor areas with moderate traffic, but not ideal for external or high-moisture zones.

Installation & Maintenance: GRP Saves Time & Money

Quick & Flexible Installation

GRP stair nosing and strips are lightweight, pre-drilled, and can be cut to size on request. They bond to a wide variety of surfaces including chequer plate, concrete, and timber, and don’t require specialist tools or downtime.

 Featured Product:
Heavy Duty 70mm x 55mm Stair Nosing Cover GRP Anti-Slip Solution
Supplied from stock, pre-drilled, and chamfered to avoid trip hazards.

Decking & Ramps?
90mm Anti-Slip GRP Strips can be screwed directly onto outdoor decking or wooden ramps — ideal for fast upgrades.

Maintenance-Free by Design

Once installed, GRP products require very little upkeep. There's no need for painting, anti-rust treatments, or sealants. Simply clean periodically with water or mild detergent.

Compare that with traditional materials:

• Aluminium needs regular checks for surface wear and corrosion

• PVC can degrade under UV exposure

• Wood must be sanded, sealed, and treated — especially in wet areas
