Anodising is a process for producing a protective and decorative film of aluminium oxide on aluminium and its alloys. The structure of the film formed is porous which enables it to absorb colours and electrolytic colouring produces a number of attractive shades. These colours are fast to light and weathering. Anodizing is the conversion of the parent metal.
Major portion of aluminium profiles are received in a mill finished state from extruders, and anodising them produces a good attractive finish. And sometimes, in order to provide a special aesthetic appeal to the metal, the profiles are given a special mechanical or chemical treatment prior to the anodizing process with a PLC controlled system. Our quality systems ensure that the finish given in anodising is of consistent thickness and colour.
The standard finishing on aluminium by anodising are:
