Application

Suitable for new build footbridges and for essential footbridge refurbishment works, including areas in close proximity to overhead power lines or electrified areas.

Description

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.


NEW Advanced 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 and Dura Slab Structural Stair Tread and Landing surface.


Features & Benefits:

  • Anti-slip surface.
  • High strength.
  • Non-corrosive.
  • Non-conductive.
  • Lightweight.
  • Single unit construction and built-in rise allows for an easy, rapid installation.
  • Built-in fall assists with drainage and reduces pooling on stair surfaces.
  • Ongoing maintenance not required: will not rot, corrode or lose colour throughout its design life.


Dura Slab Structural Stair Treads work in conjunction with Dura Slab Structural Landings.
