Anodising

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.
Anodising can provide an attractive, durable and tough finish to aluminium, enabling it to be used in many applications. 

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.
The anodising process physically alters the surface of the metal, and also provides a means of colouring the metal.
During the process the oxide layer is at first porous, and it is at this point that its possible to add a coloured dye.

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.
