Anodising

Anodising is an established surface-finishing process for aluminium. An electrochemical process produces an extremely fine, porous, hard and at first colourless oxide layer on the surface of the aluminium. Unlike other finishing processes, the oxide layer is produced from the base material itself, so that foreign material is not applied to the surface. The anodising process preserves the desirable metallic character of the aluminium. Anodised aluminium is particularly suitable for outdoor applications because the anodised layer provides a reliable barrier against corrosion. Anodised layers are also extremely hard, which makes them insensitive to abrasion and other mechanical influences.

We anodise profiles up to a length of 7400 mm and a weight of up to 50 kg per profile. In our anodising plant we process a million square metres of aluminium surface a year, which is equivalent to the area of some 250 football pitches. With coloured anodised aluminium - 400,000 square metres a year - we can supply C31 - C35 colours.
