Aluminum coils are metal products that have been cold-rolled and bent after passing through a casting 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 cutting. Moreover, the aluminum coils can resist corrosion from saline, alkaline, and acid rain, and they do not corrode or produce toxic bacteria, release any toxic gases, or cause rusting of the frame or fasteners.

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

Based on the different metallic elements contained in aluminum coils, the classifications vary, allowing for selection and customization according to the product's application range.
