Dura Composites’ system speeds 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. No heavy lifting equipment is needed as all panels can be easily manhandled even in full stock lengths.
