Anodised Aluminium Profile

Anodising is one of the most common used coating types. Electrochemical process is used for anodising. Anodising thickens and strengthens the existing thin natural oxide coating. Firstly, pretreatment has done in acid/alkali solutions to remove dirt, grease and impurities. Secondly, etching process has done on the surface to make it rough. Then, it is brightened to a smooth surface to receive coating. Lastly, section to be coated is dipped in electrolyte and current is passed through electrolyte. Hence, oxygen formed in the electrolyte deposits on aluminium section and oxygen reacts with aluminium to form a thick oxide coating. Anodising is used to surface treat the aluminium profiles. The anodising layer improves the corrosion resistance and makes the profiles more resistant to external influences. Anodising can have done only over aluminium products. In addition, anodised aluminium profiles are highly resistant to abrasion and easy to clean and maintain.
