Anodised aluminium components or profiles can have a ‘natural’ or ‘colour’ finish.
Anodising is an electro-chemical process, which physically alters
the surface of the metal to produce a tough oxide layer on the surface.
Anodic Film Thickness
Anodising can have a varied processing time, which varies the thickness:
Anodising as an electrochemical process produces a protective aluminium
oxide film, not all alloys are recommended for anodising.
Anodising will give a high quality finish plus producing a finished product that will have excellent corrosive resistance and will not chip or peel off. Aluminium that has been anodised generally has a very long life span.
Normal anodising colours and finishes include gold, silver, black, natural, and satin. Other colours can be supplied.
Extrusions, or components can also be polished before anodising to give a bright reflective coating that has a long life.
