Heavy commuter, railway personnel 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 ageing pedestrian footbridges or rail crossings then you should consider our award-winning Dura Slab Structural Stair Treads. Dura Composites revolutionary Dura Slab Structural Stair Treads are made from high-strength GRP (also known as FRP) and are ideal for both new build footbridges and for essential staircase refurbishment works.

Rapid Installation Saves Time & Money

The Dura Composites treads and landings can be easily fixed into position thanks to their single unit construction and feature a built-in riser for rapid installation and an in-built fall to assist with drainage and reduce pooling on stair surfaces.

Available in 65mm thickness, they can span up to 2.1m clear open span, achieving the required 5kN/m2 at L/200 deflection, meaning that additional supports can be avoided in most scenarios.

The 65mm size is designed to map to the  most customary timber stair component size in common usage. Dura Slab Structural Stair Treads allow for a 10mm adjustment in each case, meaning easy replacement of degraded timber.

Why Choose Dura Slab Structural Stair Treads?

Dura Slab Structural Stair Treads incorporate a number of ground-breaking features. Their single unit construction speeds up install times, reducing costs and limiting disruption to end users. Known as Dura Slab Structural Stair Treads, they are made from pultruded GRP and are lightweight, high strength, anti-slip, non-corrosive and non-conductive. Designed for use on footbridges and staircases, they overcome all of the problems normally associated with the use of traditional materials such as wood. Whilst timber treads need regular refurbishment as they are prone to rotting which compromises the structure and provides potential “slip or trip” risks for pedestrians, our GRP treads are safe, easy to work with and low maintenance.

Where previous composite treads on the market have been limited in span capabilities, Dura Composites can span up to 2.1m clear open span, achieving the required 5kN/m2 at L/200 deflection, meaning that additional supports can be avoided in most scenarios.

Hidden fixings minimise trip hazards and provide an aesthetically pleasing finish, whilst the in-built risers act as debris shield. Added spine supports can enable greater spans with minimal deflection.

Also included is a very slight fall to assist in the prevention of water pooling which can lead to problems with ice in the winter months. No heavy lifting equipment is needed as all panels can be easily manhandled even in full stock lengths.

Tri-Tone Grit

Dura Composites’ Tri-Tone gritted surface offers superior durability and performance for high-traffic areas and blends with a range of surroundings. Independently tested (in accordance with BS 7976-2:2002+A1:2013), Tri-Tone maintains a fantastic 97.5% of its original slip resistance after 1.1 million footfalls & delivers an 8% increase in slip resistance in wet conditions vs. our previous generation Dura Platform surface.

Dura Grating Structural Treads

Our Dura Grating Stair Treads are made from the latest innovation in open mesh grating known as d2 Dura Grating.

The 45mm mini mesh d2 Dura Grating of the landings and treads is is designed to be compliant with BS 6399 to meet 2.5Kn loadings (at 0.5% / L200) deflection. This is around 30% stronger than the standard 38mm grating used by other manufacturers.

The smaller hole size of 45mm mini mesh d2 Dura Grating meets the requirements of the 20mm European Ball Falling Test and limits the risk of tools and equipment dropping through larger 32mm holes that could injure people or delay works. Furthermore, the smaller holes provide a greater sense of security and reduce likelihood of vertigo.

All treads feature DDA compliant gritted nosings in yellow as standard which have a durable full angle profile, rather than the small strips used by others, which are prone to failure.
