ASLON Aluminium Beams

ASLON Aluminium Beams are always straight and provide a very light weight substructure for porcelain tiles. Installation can be on our Aslon Rubber Pads or our Adjustable Slope Correction Pedestals.

Always install the aluminium beams (substructure) in accordance with the installation manual to which reference is made by the manufacturer of the porcelain tiles.

Available Sizes
40 x 40 x 2400mm
35 x 23 x 2000mm

Fastening Clips

Fastening clips are used to secure the decking boards to the aluminium beams. These clips can be loosened to allow removal and replacement of boards at any time without damage to the decking boards or substructure

End Fastening Clamp

End Fastening Clamps are used to fasten the first and last boards of the layout. Pushes into the ends of the aluminium beam to secure the first and last decking boards where possible.


Couplers are available where aluminium beams need to be joined. Couplers are fixed using the same quick fit connection as the fastening clips keeping installation time to a minimum and ensuring a secure connection.

Installation On Rubber Pads

Installation on our Aslon rubber pads is quick and easy. Aslon rubber pads are 100 x 100 x 10mm in size and will protect the substrate below from damage as well as allowing for free drainage. When installing on Aslon Pads the decking will simply follow the existing fall of the roof. Please contact us if you have an area with multiple fall directions. Supports should be placed under the aluminium beams no more than 500mm apart.

Installation On Pedestals

Installation on our adjustable supports allows for complete adjustment of the deck level. Using this system the decking can be installed level by adjusting the height of the supports to overcome the drainage falls of the roof. Our slope correction supports automatically adjust for the angle of drainage and fit perfectly to the aluminium beams.Supports should be placed under the aluminium beams no more than 500mm apart.

Multi Brackets

Multi Brackets can be used to attached the aluminium beams to almost any surface including timber, concrete and even existing pavers.

The Multi Bracket can also be used to connect aluminium beams together at 90 degree angles where required.
