Designed specifically for use on balconies on high-rise, multi-occupancy buildings but is also suitable for any balcony (steel or concrete inset), terrace or walkway project that has a decking requirement.


Aluminium balcony decking with a depth of 20mm. It features the same specification as the AliDeck Junior Flat Balcony Decking Board but with a ridged surface rather than flat. It is naturally fire resistant and non-combustible.

The decking is lightweight yet high in load-bearing capacity and achieves a much greater span than timber or composite decking boards, meaning it requires less underside support or supporting steelwork, thereby significantly reducing costs.


The installation time is up to 50% quicker than other products due to the quick-fit through-the-board fixing, with fixings hidden by our clip-in cover in the board.

Board spacing:

3 – 8 mm (5 mm recommended).

Features and benefits:

  • Class A2-s1, d0 fire rated, therefore conforms to the UK fire regulations for materials used on the exterior of high-rise buildings.
  • Full drainage: The aluminium decking is installed with gaps between the board (spacing recommendation above) to allow the water to drain through, away from the decking, avoiding water laying on the surface.
  • Integrated Balcony Drainage System available, consisting of between-board drainage channels and perimeter gutters, providing piped drainage.
  • Constructed from 67% recycled aluminium for strength, longevity, sustainability and minimal maintenance.
  • Quick to install.
  • Easy fix to existing steelwork without unnecessary penetration.
  • 100% recyclable.
  • Can cover any size balcony: boards are 120 x 20 mm, however they can be cut to size along the width and fitted together to cover balconies of any size.
  • Available in 4m or 6m stock lengths. Custom extrusion available above weight limit, consult manufacturer for details.
  • Minimal maintenance required: Aluminium decking does not require special treatments to keep it clean and maintained.
  • Will not warp over time: Unlike timber, aluminium does not expand or contract in the heat and wet weather and will not warp, make it last much longer than timber decking, without the need for regular treatments.
  • 90% of the deck board can be installed prior to the installation of the balcony if required, saving time.
  • No need to drill holes: Can be installed onto existing sub frame sections without having to drill additional holes.
  • Available in 13 standard colours.
  • 30 year warranty.
  • 60 year life expectancy.
