What are the differences between aluminum coil and aluminum sheet?

Aluminum coil and aluminum sheet are both flat aluminum products but differ in form and usage. Aluminum coil is a long, continuous roll of aluminum that can be easily unrolled and cut to length, making it ideal for manufacturing processes where the material needs to be fed through machines. It is commonly used in industries such as construction, packaging, and automotive for applications like roofing, siding, and food packaging. Aluminum sheet, on the other hand, comes in flat, rectangular pieces with specific dimensions and is typically thicker than coil. It is used in applications where a solid, non-continuous piece is required, such as in signage, furniture, and decorative elements. The thickness and surface finish can also vary between coils and sheets, with sheets often being available in a wider range of finishes and thicknesses.
