Jiangsu Fulilai offers a variety of cold rolled steel coil and sheet products and value-added services to meet customer needs. Our cold rolled steel service capabilities include slitting, shearing, blanking, leveling, degreasing and brushing and metallurgical support.
Advantages:Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required. Until now, cold rolled coils have been available and successfully used for a variety of applications.
