Rooftop Terrace Decking

Rooftop Terrace Decking

The Fastest Rooftop Terrace Decking System to Install on the Market

More and more professionals within the construction industry are looking to secure suppliers for non-combustible products and rightly so. Our range of Alideck aluminium decking boards and supports are the ideal product to use on roof top terrace decking areas.

We have developed a quick-to-install, non-combustible aluminium decking system which can be adjusted to the height required for your project. As a result of the large spanning capabilities of the Alideck Supa Joist, you can install our aluminium rooftop decking speedily. On a commercial loading of 4kN sqm our Supa Joist aluminium decking support will span 1.2m between centres which is 3x the span of regular composite decking subframes. This results in speedier installation because less joists are required.

This non-combustible, aluminium rooftop terrace decking has been calculated and is structurally safe to withstand high loads while alternate decking options on the market will need additional underside supports.
