It is produced by using abrasive paper repeatedly to scrape lines on aluminum sheet. The main technological process can be divided into three pats: degrease,sander and washing. In the process of scraping lines of aluminum sheet,the special skin membrane technology after anodization can make the aluminum sheet surface generated a epithelial layer contained the metal elements,each tiny silk mark is visible,it makes the metal radiant fine-hair gloss.

Place the aluminum sheet placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as anode, electrolysis the aluminum sheet in the effect of certain conditions and impressed current,then it is the oxidized aluminum sheet. Anodic aluminum is oxidized to form aluminum oxide thin layer on the surface, the thickness is 5 ~ 20 microns, hard anodic oxidation film can be 60 to 200 microns.

Namely it is the aluminum sheet with printed pattern on the back and thickness of 025 or 03 millimetre.

It refers to the aluminum sheet processed by rolling, polishing and other methods to make its surface appear like a mirror.

It is a kind of aluminum product which form a variety of decorative pattern on the surface after rolling process on the basis of the aluminum sheet, it is widely used, mainly in packing, building, curtain wall, etc.

Color coated aluminum sheet has advantages as light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed, save energy and prevent pollution.
