Dura Composites has experience in the design and supply of GRP product solutions for external infrastructure and depot works.

Our non-conductive, non-corrosive and durable product ranges are ideal for renewing or upgrading facilities to meet the changing needs of train operating companies.

Thanks to the lightweight nature of the materials and their ease of manoeuvrability, works can be easily undertaken without impacting on operational safety or the running of services which rely on these facilities every day.

Our gritted anti-slip walkways for examples are the ideal safe access to external fuelling areas, CET stations and wash-plant facilities. Made from our d2 Dura Grating they are an ideal and cost-effective alternative to traditional grating materials like wood, galvanised steel and stainless steel.

The grating is exclusive to Dura Composites and cannot be found anywhere else . It has been extensively anti-slip tested using methods far superior to those of other GRP grating suppliers, achieving anti-slip scores of more than 63 in the wet, maintaining low slip potential even after 1.1 million footfalls.

Trackside Walkways





Overline Pedestrian Bridges

Saving Time

Improved Lifecycle

Low Maintenance

Fire Resistant

Overlay solutions with gritted plate covers on to timber are not a safe and long lasting solution, accelerating the degradation of the timber substructure which is dangerous for both the public and maintenance staff.

With increasing amounts of traffic on the tracks, overline pedestrian bridges can improve safety for those needing to cross the railway line.

Dura Composites’ GRP Dura Slab Structural Stair Treads and Landings can be used as part of new build bridge construction and as a replacement for rotting timbers in footbridge refurbishments.

Extremely low-maintenance, the products will not rot, corrode or even lose colour throughout their design life, and are ideally suited to situations where the footbridge or staircase is located in close proximity to overhead power lines or electrified areas, due to their non-conductive properties.

The 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.

Structural Landings

Working in conjunction with the NEW Dura Slab Structural Treads, Dura Composites offer landing panels which can span up to 2.4m clear span (50mm thick option), achieving 5kN/m2 at L/200 deflection or up to 3.2m (using the 100mm option).

Both reduce or eliminate the need for additional supports to break spans down, providing huge advantages over other composite solutions on the market.

Dura Slab Structural Landings are designed as a modular system, allowing the contractor huge flexibility both at the design stage and on site.

Dura Composites’ unique high specification composition has been rigorously tested (in accordance with BS 7976-2:2002+A1:2013) and achieves ultra-low slip potential in both wet and dry conditions.

Structural Stair Treads

Dura Composites offer newly developed full systems to speed up install times and reduce costs, possessions and bridge closures, thereby limiting disruption to end users. The Dura systems made from GRP are lightweight, high strength, anti-slip, non-corrosive and non-conductive and overcome all of the problems normally associated with the use of traditional materials such as wood, steel and concrete.

Where previous composite treads on the market have been limited in span capabilities, Dura Composites has the ability to span up to 2.1m clear open span, achieving the required 5kN/m2 at L/200 deflection and meaning that additional supports can be avoided in most scenarios. The Dura Slab Structural Stair Tread design can be specified with built-in risers, speeding up the install process whilst increasing safety, particularly in scenarios where bridge treads are located near overhead lines or are replacing open risers.

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.
