Aluminum coil has the characteristics of lightweight, corrosion resistance and recyclability, and is widely used in construction, automotive, aerospace and other industries. According to different manufacturing processes, aluminum coils can be divided into different types, including cold-rolled aluminum coils and hot-rolled aluminum coils, etc. In addition, according to different surface treatments, aluminum coils can be divided into coated aluminum coils and uncoated aluminum coils, etc. Aluminum coils can be processed into different shapes and sizes according to customer needs, such as plates, coils, pipes, etc. The wide application of aluminum coil has changed the scope and way of application of traditional materials, and also contributes to environmental protection and sustainable development.
