Aluminium Decking for Balconies

Easy to install, fire-resistant aluminium decking system for all applications.

Our metal decking is made from T6 aluminium, making it strong and durable in a variety of applications. Due to its robust design and fire-resistant properties, it is best suited for high-rise applications over 18 metres in height, whether that be for residential or commercial projects such as high-rise apartments, schools, universities and hospitals.

Our boards feature an innovative, patent-pending tongue-and-grove design, which ensures that they can be fitted quickly and easily, without the need for cutting. Each aluminium board also has a double skin with an eye-catching grooved surface and uniform underside to prevent water dripping below the deck. The in-built grooves make the decking surface slip resistant, improving overall safety and further cementing Dura Deck Aluminium as an ideal choice for high rise balconies and building applications.

With a 150mm visible face, the fireproof decking board boasts an integrated gutter system, channelling water away from your structure to create a low maintenance deck with a useable, dry space below. Simultaneously, this creates an attractive integrated soffit detail. The grooved design offers a traditional plank-look surface that features the latest technology and can be installed rapidly – with no clips being required.

Dura Deck Aluminium comes with a 20-year manufacturer warranty, subject to a correct and proper maintenance regime.

Anti-slip coating for increased safety

Our aluminium decking boards are coated in a unique paint formulation which is specific to Dura Composites’ products and is not available anywhere else in the world! The paint coating – available in all three colours – is formulated with micro-grit, which makes the aluminium boards incredibly slip resistant in all weather conditions whilst maintaining a sleek finish. This makes our metal decking perfect for a range of high-rise applications, such as balconies and roof terraces, where safety is a primary factor for any installer.

Dura Deck Aluminium has a slip potential of 55 in the wet and 62 in the dry – the minimum requirement for ‘low slip potential’ is 36+ meaning that our  deck boards far surpass the required standard and offer phenomenal slip resistance.

Improved loading capacities

Unlike traditional balcony materials, our aluminium decking boards can be easily fitted on top of a metal joist or a flat concrete base, both of which perfectly complement the fireproof decking qualities. If you opt to install our boards on joists, they can have up to 1 metre clear span, reducing the number of joists you need and saving money on your substructure.

What’s more, our metal decking boards are perfect for any retro-fitting projects, being quick and easy to install and offering a range of benefits that will improve the service life of your building. Our balcony decking has a 2 kN per metre point load, far in excess of what is required by the British Loading Standard.

Dura Deck Aluminium gives developers and contractors the ultimate peace of mind when it comes to finding new or replacement balcony decking for applications over 18 metres in height.
