Aluminium Decking Frame Systems for Modern Decks

Building a deck in Australia is bound to come with challenges. Timber decking frames have been the usual option for many years now. However, they often face issues such as warping, rotting, and damage caused by termites. A more stable option would be an aluminium decking frame. This makes the installation process simple and performs better as time goes on, which is ideal for both homeowners and builders working on a decking project.

​

Aluminium decking frames are strong, lightweight, and long-lasting, giving any deck a solid foundation. Because of their durable nature, supports can be spaced farther apart, reducing the number of parts and speeding up installation. They are suitable for a range of deck designs, from modest backyard decks to massive outdoor entertainment spaces, because they work with wood or composite boards and support systems like click decking or waterproof membranes. Even in challenging Australian environments, an aluminium frame for decking remains sturdy, level, and aesthetically pleasing with little upkeep.​

This is suitable for coastal salt air or hot inland summers, as aluminium framing is lightweight and built to resist corrosion. Aluminium joists and deck frames resist twisting, warping, or shrinking, unlike timber decking. The added stability helps make the installation process a lot smoother, with less fixing required during or after construction.​

The strength of the material means supports can be spaced further apart, potentially cutting down on the number of components required—consult Spanmor's span charts for project-specific details. This helps get the job done faster on site, especially on projects where ground conditions vary, while also reducing labour costs, simplifying installation, and improving overall structural efficiency and safety.

Aluminium decking frames are known to work well with both composite decking and timber decking. The click deck system option allows boards to clip into place, which creates a much cleaner finish without the visible fasteners. This framing system supports different board types, so if you want a more natural appearance, you can choose timber decking. And for lower upkeep composite decking is the ideal choice. This setup works well for a wide range of decking options.​

This setup is suitable for a variety of deck types, including elevated aluminium decks and ground-level patios. Regardless of the material, installation is made simple by the sturdy support provided by aluminium joists. While timber decking easily integrates with waterproof membranes on rooftop projects, builders value how composite decking works with height-adjustable pedestals for sloped sites. The outcome? A deck with a sleek appearance that fits your site's requirements and style, supported by sturdy deck frames that won't shift or warp.​

Deck construction can be complicated by slopes or irregular sites, but what can help level the surface in aluminium decking frames is height-adjustable pedestals. All you have to do is first place the aluminium joists, set the pedestals, and adjust the height as needed.​

This approach suits Australia’s varied landscapes, from suburban slopes to coastal areas. This method not only makes the decking project much more manageable but also reduces the need for major groundwork.​

Decks built over living areas, concrete slabs, or rooftops need good waterproofing. Aluminium decking frames work well with waterproof membranes because, unlike timber, they don’t absorb water. This helps prevent water damage in high-up or exposed areas. Aluminium is non-porous and resistant to corrosion, so it stays strong and stable even in heavy rain or humid conditions. Builders and homeowners like this combination because it keeps the space under the deck dry, stopping problems like mould, rot, or structural damage. Over time, it means the deck lasts longer, needs less upkeep, and performs reliably in all kinds of Australian weather.​

Aluminium framing makes transporting and handling much easier during installation by balancing strength and low weight. Aluminium joists and deck frames are engineered for extended spans suitable for most residential decks—refer to Spanmor's downloadable spec sheets for exact capacities.​

There is very little maintenance required, with no termite inspections or rot treatments, although periodic coating and fastener checks are recommended in harsh environments. Depending on features such as height-adjustable components, systems typically cost between AUD 160-280 per square metre. These starting prices may compare favourably with timber in the long term when upkeep is factored in. Use Spanmor’s Deck Calculator for accurate quotes.
