Heavy commuter, shopper or general foot traffic can take a toll on stairs and walkways, making them slippery and dangerous. If you’re looking to improve the safety of footbridges or staircases then you should consider our award-winning GRP Dura Slab Structural Stair Treads and Landings which not only enhance safety but also minimise maintenance needs thanks to their 60-year design life.
Suited for both new footbridge builds and staircase refurbishments, our Dura Slab Structural Stair Treads, combined with our d² Dura Slab 50 for landings, deliver a number of innovative features. Our footbridge solutions meet or exceed all listed standards, ensuring complete customer confidence.
Made from pultruded GRP, these treads are lightweight, high-strength, anti-slip, non-corrosive, and non-conductive — outperforming traditional materials like timber. While wooden treads often require frequent maintenance due to rotting and can create slip or trip hazards, our GRP treads are safe, low-maintenance, and built to last. Their single-unit construction speeds up installation, saving time and reducing costs, with no heavy lifting equipment required.
Hidden fixings minimise trip risks and create an aesthetically pleasing finish, while built-in risers act as debris shields. Optional spine supports allow for greater spans with minimal deflection, and a slight fall in the design prevents water pooling, reducing the risk of ice formation in winter. Designed for durability and convenience, our solutions ensure a safer, stronger, and more efficient installation.
Unlike traditional composite treads, our GRP stair treads offer an impressive clear open span of up to 2.1 meters. They achieve the required 5kN/m2 at L/200 deflection, eliminating the need for additional supports in most scenarios, reducing installation complexity and cost.
Our Tri-tone gritted surface provides excellent durability and performance in high-traffic areas. Independently tested to BS 7976-2:2002+A1:2013, it retains 97.5% of slip resistance after 1.1 million footfalls, with an 8% improvement in wet conditions compared to our previous Dura Platform and Dura Slab surfaces.
Dura Slab Structural Stairs and Landings achieve a Class B rating according to EN13501-1. Ideal for areas near powerlines or electrified zones, these non-corrosive and non-conductive footbridges provide a safe, reliable solution for replacing degraded timber treads.
Category | Requirement | How We Meet This Standard |
---|---|---|
Structural Requirements | Minimum load capacity of 5 kN/m² for pedestrian use | ✅ Tested and certified to exceed BS 4592 load capacity standards. |
Durable and corrosion-resistant materials | ✅ Constructed using high-strength yet lightweight, non-corrosive Glass Reinforced Polymer (GRP) materials. | |
Compliance with testing protocols (e.g. BS 4592) for load capacity and deflection limits | ✅ All products independently tested in line with BS 4592 protocols. | |
Accessibility Requirements | Adherence to Disability Discrimination Act (DDA) and Access for All (AfA) guidelines | ✅ Inclusive designs ensure compliance with DDA and AfA regulations. |
Inclusion of tactile paving and high-contrast markings | ✅ Tactile paving and contrast elements are standard in all designs. | |
Non-slip surfaces and minimum tread depths for safety | ✅ Anti-slip finishes and precise tread depths for maximum pedestrian safety. | |
Fire Safety Standards | Fire-resistant materials suitable for railways | ✅ Use of non-combustible materials and fire-retardant coatings for public and rail safety. |
Compliance with fire safety regulations like EN13501-1 | ✅ Materials certified to EN13501-1 standards. | |
Maintenance and Inspection | Low-maintenance materials that resist rot and corrosion | ✅ Pultruded GRP materials resist corrosion, rot, and wear, reducing upkeep. |
Clear guidelines for regular inspections | ✅ Comprehensive guides and our Preventative Maintenance Inspection (PMI) service ensure long-term safety. | |
Health & Safety Regulations | Requirements for safety edge protection | ✅ Handrailing and barriers exceed Network Rail standards. |
Non-conductive materials for electrified rail safety | ✅ Non-conductive GRP materials protect against electrical hazards. | |
Aesthetic & Environmental Considerations | Designs must be visually appealing and blend in with surroundings | ✅ Multiple custom finishes to blend in with local settings. |
Innovative approach to materials with focus on sustainability | ✅ Verified Environmental Product Declarations (EPDs) provide transparency on the environmental impact of our GRP products throughout their lifecycle. |
Check out this video to view one of our successful staircase replacement projects completed in just 52 hours. The degraded timber staircase was removed and replaced with a prefabricated galvanized steel frame topped with GRP Dura Slab Structural Stair Treads which have a 60 year design life and advanced anti-slip surface. Panels are pultruded in single sections for rapid install and are also lightweight, making them easy to handle manually without the need for extensive lifting equipment.
Not only have we saved over 5 million kgs of CO2 through our d² product innovation so far, but we’ve also embarked on a project to recycle all our GRP. If you have GRP waste materials from your on-site installation, or if your Dura product is end of life – it will be repurposed into the production of new materials at our UK HQ. A real-world solution to a real-world problem, which means you can have total peace of mind that you’re choosing a great sustainable material option for your project.
