Anodised Aluminium Extrusions
Anodizing is an electro-chemical process, which physically alters the surface of the metal to produce a tough oxide layer on the surface.
It is mill finished aluminum next surface treatment products, the anodizing production will be done in the tanks for the anodizing film, which can increases the thickness of the oxide coating on the aluminium improving its resistance to abrasion. The anodizing processes can be alkali etching and acid etching; also some extruders make the polishing, sand blasting or shot blasting operation on the aluminum profile before anodizing to remove the die line and scratch.
COLORS & SURFACE FINISH
the anodizing color can be matt silver, anodized champagne, anodized bronze, anodized black, anodized gold and some other colors.
it is widely used in window and door, curtain wall, industrial profiles and decoration profiles.
