Cold-rolled steel sheet is a type of steel product that is processed at room temperature, typically after hot rolling, to achieve desired dimensions and surface qualities. It undergoes a process of cold reduction, which involves passing the steel through rollers at room temperature to reduce its thickness and improve its surface finish. Cold-rolled steel sheets are commonly used in various industries such as automotive, construction, appliance manufacturing, and others due to their smooth surface, uniform thickness, and enhanced mechanical properties. They are often preferred for applications where precision and consistency are critical.
