Ali-Deck Supa Joist
The Ali-Deck Supa-Joist is an integral part of the Ali-Deck System! This clever extrusion is designed to act as both a support post and big span joist. The connection plates allow for super fast installation and can be adjusted to suit most applications and conditions.
It has also been designed to be connected together to give additional strength for applications where larger spans are required. The Supa Joist system can be used as a standalone solution and can be used in conjunction with composite and timber decking solutions.
This all aluminium system is unique and modular so it can be extended to any length, it can also be simply connected together to create double the span
depending on the desired foundation spacings, see loadings for single joist span capabilities.
- Traditional timber support structures are manufactured from timber which normally means a joist every 400mm, the beauty of the supa joist is that when used with the Ali-Deck system it only needs installing every 1900mm / 1200mm (depending on the loadings that are required) which means quicker installation.
Aluminium will never need maintenance like timber, it will not crack, warp, or swell, it’s impermeable to insects and deterioration, easy to cut and is fade and stain resistant!
