Aluminium Joist FAQs
Are aluminium decking joists easy to install?
Yes, aluminium joists are lightweight and easy to handle. They can be quickly secured into place using self-drilling screws, and the spacing of pedestal supports at 1.2m further simplifies the process.
How do aluminium joists compare to timber joists?
Aluminium joists are more durable and weather-resistant than timber. They won’t warp, rot, or crack over time, making them a more reliable choice for decking substructures in outdoor environments.
Alternatively for non raised decks, our composite joist may be a more affordable option.
Can aluminium joists be used for both residential and commercial decking projects?
Yes, aluminium decking joists are suitable for both residential and commercial projects. Their strength, corrosion resistance, and ease of installation make them a versatile option for any decking application.

These decking joists were used alongside a local steel fabrication company, as the underside of the deck is visible and required a clean, tidy finish. They were an excellent choice—well finished, lightweight, and very strong. Delivery was prompt via their own team, which was a nice touch. I will definitely be returning for future purchases. Very satisfied.
Excellent quality . Very well made . Light but very strong .
I would definitely recommend these to friends and family .
Absolutely brilliant
Very happy – very easy to work with to produce a high quality finish for steps and seating that should last for years.
Excellent products. We employed a joiner to create an extension to our glass canopy, using the materials bought from you. We are more than happy with the work and the materials used.
