Aluminium Deck Frame System

No one can argue that well maintained, quality hardwood decking is a great product and looks fantastic. But how about what’s under the deck?

Timber subframes can often rot over time as moisture sits under the decking. As well as degrading it can also move as it absorbs moisture and then dries out, potentially ruining your floor above. Plus, it can twist and warp, especially if it is too close to the ground or close to floor level and has poor spacing and there is not enough airflow under your deck.

Our joists do not suffer from any of these problems so when considering the best framing for your deck you should seriously consider using premium aluminium. Just like the timber under your deck, the boards themselves need to be carefully assessed. If you are prepared to spend time and effort maintaining your hardwood decking, that’s fine but if you would rather sit on the deck and relax, a Futurewood low maintenance composite decking option combined with an aluminium subframe is the perfect solution for you.

Introducing the future of decking: Futurewood’s CleverDeck Structural Aluminium Subframe System – design registered – the perfect complement to our CleverDeck range of composite decking boards!

High-Quality Decking System

Our structural aluminium deck framing includes a range of three different sized high-load capacity joists and adjustable pedestals along with quick fix brackets and clips to allow you the option of constructing a rot proof subframe to support your CleverDeck composite decking boards.

This is the ideal solution for every customer, a great product that can be used in just about every situation, including in tight spaces where you would like a deck to be built so that can flow from indoor to outdoor without a step, but there are maximum height limitations that conventional decking systems, including those using LVL beams, don’t meet.

The specially designed aluminum profiles come in sizes of 25mm, 50mm, and 90mm with a high load capacity. By using either individual joists or in combination with bearers, you can span between 600mm and 1800mm, depending on the design of your deck and the surface it is being built on.

The system covers a range of sizes from 48mm to 523mm starting with a 25mm joist fixed directly to the concrete. The pedestals adjust to cover a range from 14mm to 320mm. This range of pedestal sizes combined with a joist or joist/bearer combination provides the perfect grid system to support your CleverDeck composite decking boards and allows you to build your deck across a range of heights from 62mm to 523mm. For higher decks, we recommend using re-blocking stumps instead of our pedestals.

The black powder coated joists and bearers use a range of innovative quick fix clips, brackets, and screws to fix together and create a level and stable surface to fix your decking to. They literally snap in place on the top plate of the pedestal, no screws required just a simple “click”! The special registered design of the aluminium profile and brackets allows for different fixing options that require only 1 screw per bracket/clip meaning that there is minimal labour required to connect the framing and produce a perfectly level and square deck subframe using straight lengths of lightweight aluminium.

The 14mm pedestals and the 25mm high joist have been designed to provide the perfect solution for ultralow deck requirements used together on concrete or tiled patios/balconies where there is insufficient height to use the  traditional stump, bearer, and joist construction. The combination of a 25mm joist with an adjustable pedestal creates a grid support system that is much lower than you can achieve using a stump/ LVL, pine or hardwood bearer/joist subframe.

The system enables you to build a deck where the height of the deck (including the decking material and the subframe) needs to be less than 100mm.

The Subframe System is supplied with all the components necessary for the builder or competent DIY to get the job done. The unique clip system is quick, easy, and user friendly saving time and money and making it a very cost-effective alternative to a traditional timber subframe.

The full range of pedestals and joists/bearers that make up the subframe can be fixed over existing concrete or tiled patios/balconies where there isn’t enough height to have traditional stump, bearer, and joist subframes. The system can also be built using traditional concrete pads positioned, in the ground, in an appropriate grid pattern for the span of the joist/bearer.

In some instances, you can build a very low height system over bare earth, for this scenario the earth needs to be well compacted and well-drained. You will also need to lay a geo-membrane over the earth and position appropriate pavers in a 600mm x 450mm grid pattern to place the pedestals on.

A detailed technical drawing of the subframe can be supplied for each installation and this can be certified by a structural engineer where required.
