ANODISING PROCESS
 
What is anodising?
   
 

Anodising is an electrochemical process. During the process, the aluminium profiles are immersed in an acid solution and an electrical current passes through to produce an uniform aluminium oxide film on the profiles.

   
   
Why aluminium need to be anodised?
   
 

When attacked by the environment, aluminium profile in its bare form (mill finish) will form a layer of oxide on its surface. This oxidation is a form of corrosion and it affects the appearance of the metal. Anodised film, on the other hand, is extremely hard, durable and resistant to corrosion. It offers a number of gloss and colour alternatives. Unlike powder coating, anodising allows the aluminium profile to maintain its metallic appearance.
