Rolling changes the structure of the material. By rolling it in the right way, we make extremely strong steel for cars, or thin and light steel for tins. After rolling, we apply a thin layer of tin, paint, zinc or plastic coating, depending on the purpose. Then we package it before it goes to the customer.
