Aluminum coils are metal products that have been rolled, bent, and processed after passing through a casting and rolling mill. The surface of the aluminum coils has no high-temperature pressing marks. The sheet surface has no residual stress and will not deform after shearing. Moreover, aluminum coils can resist corrosion from salt, alkali, and acid rain, and they do not corrode or produce toxic bacteria, emitting no toxic gases, and causing no rusting to the framing or fasteners.

Now, aluminum coils are widely used in electronics, packaging, construction, and machinery.

Aluminum foil is categorized differently based on the various metallic elements it contains. Selection and customization can be made according to the product's application range.
