Cold rolled steel plate exhibits excellent performance and smooth surface. It applies to automobile industry, refrigerator, washing machine, construction field and industrial equipments. Cold rolled plate will be turned into the necessary material for future world.
Categories of cold rolled products
Hot rolled acid pickled steel coil, rolled hard steel coil, common cold rolled steel coil,(electricity plated zinc galvanized steel ,finger tips free plate, hot rolled zinc galvanized steel).aluminum galvanized ,electricity plated tin ,color coated (mechanic sheet) and so on.

1、Hot rolled acid pickled

2、Rolled hard steel coil：Roll the hot rolled acid pickled steel coil under usual temperature.
Features of parts：As this kind of steel hasn’t been annealed ,the hardness is pretty high and difficult to proceed mechanic processing. Only the deformation less than 90 degree is practical (vertical to coiling direction).
Application Scale ：
（1）Processed into common cold rolled steel after annealing
（2）Zinc galvanizing is conducted prior to annealing.
（3）Steel plate which doesn’t need any processing .
Frequently used designation
CDCM - SPCC （SPCD、SPCE、ST12、ST13、ST14、BLC、BLD、BUSD、BUFD、BSUFD等），
CDCM - SPCC （SPCD、SPCE、ST12、ST13、ST14、BLC、BLD、BUSD、BUFD、BSUFD and so on.Steel of those designation share similar properties.

3、Common cold rolled products；

4、Zinc galvanized steel ；

5、Aluminum galvanized steel ：The surface of steel is composed of 55% aluminum, 43.4% zinc and 1.6% silicon by the continuous zinc melting formula .
Features of products：
（1）More durable and longer shelf life than that of zinc galvanized steel plate；
（2）Highly heat resistant ,seldom aberration in high temperature.；
（3） Excellent heat reflect；
（4）Shiny silver surface ；
（5）Similar processing properties and coating properties as that of zinc galvanized steel plate；
（6） Excellent welding property。
Application : zinc galvanized steel plate。

6、 Electricity plated tin:。

7、Color coated steel ：

8、Mechanic steel 。
