Description

Aluminium joist that has been designed as a standalone product to be used with Alideck standard aluminium decking, slip-resistant aluminium decking and fire resistant balcony decking. It complements the Alideck System and enables quick installation times. It can also be used as a standalone solution in conjunction with composite and timber decking options.

This aluminium system is unique and modular, and can be extended to any length. It can also be simply connected together to create double the span, depending on the desired foundation spacings.

Unlike timber, it will not crack, warp, or swell, and is impermeable to insects and deterioration, easy to cut, and is fade and stain resistant.

Features and benefits:

  • 100% aluminium construction.
  • Less joists needed: Compared to traditional joists such as timber, joists are required every 1900 mm or 1200 mm instead of every 400 mm (when used with the Alideck system).
  • Quick installation.
  • Eco-friendly: 30% of the aluminium used is recycled, and the whole Supa Joist can be recycled multiple times in the future.
  • Long lasting; naturally rust resistant, and doesn't require regular maintenance or treatment.
  • Coated with QUALICOAT five-stage powder coating finish for additional protection and longevity.
  • Two colour options are available.
  • Fire rated.
  • Will not crack, warp or swell.
  • 30-year warranty.
