Aluminum coils are thin sheets of aluminum that are rolled into a coil shape for easy handling and transportation. They are widely used in various industries, including construction, automotive, and packaging, due to their lightweight, corrosion resistance, and excellent thermal conductivity. These coils can be further processed into different products, such as aluminum siding, cans, and heat exchangers. The manufacturing process involves melting aluminum, casting it into sheets, and then rolling it into coils. This versatility makes aluminum coils a popular choice for many applications.
