Aluminium Anodised Rainscreen Cladding Finishes

Anodising is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

Benefits of anodising

Due to the nature of the anodising process and the tight quality controls on both the aluminium and the surface treatment, anodising has a homogeneous (matching & consistent) appearance.

Colours, textures and patterns can be incorporated in the anodic film, enhancing the natural metallic appearance without affecting the total UV resistance of the rainscreen cladding.

Anodising enhances the natural qualities of aluminium further; it permits a strongly contemporary finish with incomparable corrosion and abrasion resistance.

Aluminium is exceptionally recyclable, requires minimal maintenance and has proven lifetime performance.
