Aluminum sheet undergoes a rolling process to be manufactured, known as rolling. This process entails passing a preheated aluminum ingot through a succession of rolling mills. The initial step involves heating the ingot to a specific temperature to enhance its malleability. Once heated, the ingot is then fed through a sequence of rolling mills, wherein it is continuously pressed and stretched to reduce its thickness and increase its length.
The rolling mills consist of a pair of rotating cylinders with grooves on their surfaces. As the ingot passes through these cylinders, it undergoes compression and elongation, resulting in a thinner and longer sheet. This process is repeated multiple times, with each pass further reducing the sheet's thickness.
To maintain the desired thickness and dimensions, the sheet is periodically subjected to annealing. This process involves heating the sheet to a specific temperature and gradually cooling it. Annealing helps alleviate internal stresses and ensures the sheet retains its desired properties.
Once the desired thickness is achieved, the aluminum sheet is cooled, trimmed, and either cut into specific lengths or rolled into coils for further processing or distribution. The final product is a flat, thin, and versatile sheet of aluminum that finds applications in various industries, including construction, automotive, packaging, and electrical appliances.

To maintain the desired thickness and dimensions, the sheet is periodically annealed, which involves heating it to a specific temperature and then slowly cooling it. This annealing process helps relieve internal stresses and ensures the sheet retains its desired properties.
Once the desired thickness is achieved, the aluminum sheet is cooled, trimmed, and cut into specific lengths or rolled into coils for further processing or distribution. The final product is a flat, thin, and versatile sheet of aluminum that can be used in a wide range of applications, from construction and automotive industries to packaging and electrical appliances.
Aluminum sheet is made through a process called rolling, where a large aluminum ingot is passed through a series of rollers that gradually reduce the thickness of the metal until it reaches the desired sheet thickness. This process helps to improve the strength, flexibility, and surface finish of the aluminum sheet.
