Common cold rolling is short for common carbon structural steel cold rolling plate. Due to rolling at room temperature, no oxide scale is produced, so the cold plate surface quality is good, the size precision is high, plus annealing treatment, its mechanical and technological properties are better than hot rolled thin steel plate. It is widely used for common flat plate, shallow blanking, drawing die and coating substrate (tinplate, etc.).
