    Low maintenance with a design life of 60-years.

    Dura Deck® Aluminium Positive-Drain decking is engineered for superior performance and safety, making it the ideal choice for balconies and elevated spaces. Available in 18mm and 27mm thicknesses, its innovative patented profile (Patent No. GB 2 615 096) offers positive drainage, ensuring efficient water management by guiding rainwater to a gutter across areas exceeding 6m².

    With a 150mm visible face, the Positive-Drain planks combine exceptional fire safety with modern functionality, achieving a Class A2 fl-s1 fire rating, essential for mid and high-rise buildings. The robust double-skin construction features an anti-slip surface for added safety and a smooth underside that creates an integrated, attractive soffit detail.

    Our aluminium decking is designed for durability and sustainability, being 100% recyclable at the end of its life to support a circular economy. Advanced engineering reduces material use by up to 25%, lowering our carbon footprint without compromising performance.

    When paired with Dura Bearers and Dura Pedestals, this system offers a fully Class A2 fire-rated, low-maintenance flooring solution. All Dura Deck Aluminium products are UKAS accredited, delivering reliable performance and peace of mind.

    • 60% quicker to install than other fixing methods.
    • Meets NHBC BS 8579 balcony drainage standard.
    • Large spans reduce the cost of required balcony steelworks.

    The trims are simple to use and provide a robust system to start and finish your aluminium deck. The Starter Trim dictates the alignment for each subsequent decking board and features a hidden screw fixing channel which also ensures a barefoot friendly deck.

    The End Trim can be used to provide a neat finish to any exposed ends of boards following your Dura Deck Aluminium installation and the optional Closing Trim can be applied to clean up the ends of the boards and for closing the run for water.

With varying heights of pedestals and bearers, our system provides the most economical substructure combination on the market. The Dura Aluminium System is suitable for use as a decking substructure on external balconies, terraces, gardens, industrial flooring and for use as cladding battens.
