The AliDeck Story

As part of the Milwood Group, AliDeck’s founders have decades of experience in manufacturing, supplying and installing aluminium outdoor living products. Here’s the story of how they developed and took to market the most innovative and complete aluminium decking system in the UK.

AliDeck aluminium metal decking is part of the Milwood Group

“When installing canopies and verandas for schools and local authority establishments, a common issue that we heard from our customers was that their third-party supplied composite decking and PVC canopies often quickly broke down or developed problems relating to the expansion and contraction of the plastic-based materials. While our aluminium products solved the issue when we replaced their PVC structures, the faults would soon redevelop in any new composite decking they had installed alongside it. It quickly became clear that using aluminium for the decking would provide a completely stable package for our clients, so we set to work developing a solution.

AliDeck aluminium metal decking slip-resistant Class B decking board

Our first decking product was our anti-slip Class B Board. This board was designed with rubber inserts in order to provide an unrivalled level of slip-resistance performance, a crucial safety factor considering its intended deployment to schools and public areas as well as domestic settings. Launched with the AliDeck Supa Joist, our first complete decking system was warmly received by our clients and saw healthy sales and many installations.

We then developed a more cost-effective 100% aluminium decking board, our Interlocking Board, forgoing the rubber inserts which added to the production and install cost of the Class B board. Designed for compatibility with the Supa Joist, the Interlocking Board delivered a seamless finish, hid the fixings as did the Class B Board, and allowed for very fast decking installations. This board proved highly popular and made a big impact in the market, so much so that we were approached by a steel balcony fabricator who wanted to use the board on their balconies. We submitted the board for fire-resistance testing to ensure that it met the specification of their customers and were delighted to receive an A-rating for fire-safety (A1), satisfying requirements.

AliDeck aluminium metal decking A-Rated Standard Interlocking Board

With the Interlocking Board providing a sealed surface, with no gaps between the boards, the question of drainage was raised by our steel balcony fabricators. Our in-house Research & Development team went back to the drawing board and soon came up with a proposal for a whole new approach to decking boards, utilising smart profile design to introduce a gap between each board once installed for drainage. Another novel feature was the quick-fit through-the-board fixing method, hidden by a clip-in cover running the length of each board. This simple but ingenious idea removed the need for fiddly fixings between each board or using awkward fixing clips and really sped up installation. The new AliDeck System was launched with 30mm and 20mm boards and a range of joists and pedestals, allowing incredible flexibility for various build-up heights.

This innovative new range was a hit with balcony fabricators across the UK and the rest, as they say, is history!”

– Richard Izzard, AliDeck Managing Director.

AliDeck Aluminium Metal Decking and Fire Safety

Following the Grenfell Tragedy, it became imperative that fire-safety regulations with regards building materials were updated to prevent such a dreadful incident occurring again. The UK Government banned the use of combustible materials on new or refurbished high-rise homes in December 2018 and subsequently issued an Advice Note to clarify the impact of these new regulations on balconies. In March 2020, The Fire Safety Bill began its journey towards legislation with its First Reading in Parliament.

The AliDeck System has been fully tested for fire safety and has achieved Euroclass ratings of A1 and A2fl-s1, confirming that AliDeck decking boards, joists, pedestals and accessories are non-combustible and meet the new safety requirements for use in new-build and refurbishment projects.

The first element is regards combustibility and is rated from A to F, with A representing non-combustible materials. The second element relates to smoke emission level and is rated 1 to 3, with 1 indicating smoke emission as weak or absent. The third element relates to production of flaming droplets and is rated 0 to 2, with 0 indicating no droplets produced. Finally, the inclusion of “fl” indicates that the products have been specifically tested for flooring applications.
