Cold-rolled coils are sheet materials produced through the cold-rolling process, where the material is rolled into a cylindrical shape. After undergoing various processing treatments, they can be transformed into different forms of cold-rolled coil products.
Cold-rolled coils are characterized by high strength, good ductility, smooth surface, and precise dimensions.
