Cold rolled steel coil
Cold rolled steel coil(Cold rolled sheet) is of good performance, and thinner and more precise cold rolled strip steel and steel sheet are made from cold rolling. It is featured by high evenness, cleanliness of surface, many varieties, wide application, high pressing property, and low yield point. Due to the features above, cold rolled sheet are mainly used in automobile, printed metal pail, electric product, automobile, aviation, exact ammeter, can, building materials, and bicycle, etc. Additionally, it is the best material to manufacture organic coated strip.
