  • Drainage between the decking boards

  • 100% recyclable

  • Accessories available including supa joists, low joists, adjustable pedestals, drain channel, nosing profile, starter trim and end plates

Additional Features & Benefits

Excellent Fire Rating: The Alideck aluminium decking boards are manufactured from structural grade 6063 T6 aluminium which is A2-s1, d0 fire rated and 100% recyclable.

Expansion: Our deck boards will only expand on a 10 degree increase in temperature 1.6mm over a 6m length.

Will not Warp, Bend or Rot: Because our deck boards are manufactured from aluminium, they will not warp, bend or rot unlike traditional timber decking. They also do not require treatments, staining or painting once installed.

Easy to install: Our boards are quick and easy to install with installation times that are to 50% quicker than traditional decking. The balcony decking can be assembled before arriving on-site enabling you to install 90% of the balcony decking before-hand, saving time on-site.

Drainage between the boards: You have the ability to choose the space between the boards, depending on how quickly you want the water to run through, you can choose between 4mm to 10mm between boards. (we recommend 6mm as standard). The balcony boards are available with a drain channel which enables you to direct water to a specific area such as downpipes or drains.

AliDeck Safety Testing for Deflection, Slip, and Accelerated Wear Explained

Boards acting as cantilevers

Quite often you may find yourself in a situation where you need to run the boards past the end of a beam/joist, so we felt it was important to test the cantilever effect of a board running past the last load-bearing beam. The Case where 50% redistribution is considered assumes that a suitable rigid end trimmer is provided to enable 25% of the load to spread to each adjacent board. The case of 25% redistribution assumes that the load can only spread to one side, such as the end of a set of boards.

The findings are as follows (Deflections are limited to Span/180 in accordance with BS 8118 – “Structural Use of Aluminium”):

AliDeck Aluminium Decking Board Cantilever Values
AliDeck Aluminium Decking Board Cantilever Values

We confirm the 20mm board can cantilever 150mm and the 30mm board 250mm. If additional cantilever values are required, connection of boards would increase the achievable cantilever).
