The significance of cold strip mills lies in their ability to produce metal strips with precise thickness and surface finish. While hot rolling processes are conducted at elevated temperatures, cold rolling involves the deformation of metal at or near room temperature. This practice not only enhances the strength of the material due to strain hardening but also improves the dimensional accuracy and surface finish. As a result, cold-rolled products exhibit superior mechanical properties and are often preferred in sectors such as automotive, construction, and manufacturing.
