We design, fabricate and supply cost-effective, practical and safe GRP access structures using our market-leading d2 Dura Profile, Dura Grating and Dura Handrailing components. Heavy duty, non-conductive, non-corrosive and chemically resistant, they provide a lightweight and durable alternative to steel, other metals or wood.

Our specialist fabrication team boasts an impressive project portfolio fabricated within our East Anglian workshop, where Dura Composites is certified to ISO-9001 – the International standard for Quality Management. and use the latest technology, such as computer numerical controlled (CNC) machines, to produce intricate and bespoke designs.

We offer a number of stepover access systems that can be easily specified on our website using our simple configurator. Our standard duty Access Structures have been designed to the stair configuration, height, and obstacle width of your specific project. Simply select your project site parameters to view available designs with pricing.  Both straight and U-Shaped 180° turn configurations are available.

We also offer a bespoke access structure fabrication service. Our most commonly requested bespoke GRP fabrications include Driver Hop-Ups, Machine Access, Embankment Staircases, Vehicle Access Steps, Roof Walkways, Trackside Walkways, Mezzanines, Handrailing, Gantries, Stepovers and Ladders.

Reasons to choose us


Long-term performance

All individual components are individually tested to ensure performance. Handrail loadings achieve a 17mm Deflection at 0.36kN and landings achieve a 1.5kN Point Load / 2.5kN UDL @L/200. Stair tread Loadings achieve 6.1mm deflection at 1.51kN Point Load (100x100mm Square on the front edge – 800mm Clear Span).


Anti-slip tested to 1 million Footfalls in all weathers

All flooring components have been anti-slip tested for the equivalent of over 1m footfalls, achieving anti-slip scores of more than 63 in the wet even after 1m footfalls.


Belt and braces support structure

Our standard supporting framework utilises 203mm GRP channel or our unique 203 box channel, versus the commonly used weaker 150mm channel. Uniquely in the market, all our profile components meet the E23 grade performance requirement of the BS EN 13706 standard (which covers the specification of GRP pultruded profiles) and provides greater
strength and consistent quality.


Class B fire rating

d2 Dura Grating GRP flooring achieves a classification of Bfl s1 – meaning very limited contribution to fire, with the lowest possible smoke emissions.

Choosing a fabricated GRP solution from Dura Composites significantly reduces the man-hours on site and can help to compress a project schedule.

Our fabrications are constructed from the latest GRP composite product design, technology and manufacturing techniques known as the d2 product range, and are suited to all types of industry. The d2 product range of performance-improving composites is exclusively available from Dura Composites and is fast becoming the new industry standard. d2 products extensively used in our fabrications include E23 grade GRP Dura Profile and 45mm mini mesh but other Grating thicknesses are available to meet client specific loading requirements. All flooring components of our fabrications have been anti-slip tested for the equivalent of over 1m footfalls, achieving anti-slip scores of more than 63 in the wet even after 1m footfalls.
