Cold rolling

Cold rolling is a metalworking process where metal sheets or strips are passed through rollers at room temperature to reduce thickness and improve surface finish. This process increases the metal’s strength and hardness through work hardening, resulting in a smoother, more precise product. Cold rolling is commonly used for making materials like steel and aluminum in industries such as automotive, construction, and packaging. It allows for tighter tolerances and better surface quality compared to hot rolling, which occurs at higher temperatures. Overall, cold rolling enhances the durability and appearance of metal products while maintaining dimensional accuracy.
