Cold rolled steel
Cold rolled steel is rolled at room temperature and then rolled again below its recrystallization temperature. This process enables better control over finished product shape, thickness, dimensions, and a more consistent finish.

Cold rolled coil grade
1. The Chinese brand No. Q195, Q215, Q235, Q275--Q-the code of the yield point (limit) of ordinary carbon structural steel, which is the case of the first Chinese phonetic alphabet of "Qu"; 195, 215, 235, 255, 275 - respectively represent the value of their yield point (limit), the unit: MPa MPa (N / mm2); due to the comprehensive mechanical properties of Q235 steel strength, plasticity, toughness and weldability in ordinary carbon structural steel The most, it can better meet the general requirements of use, so the scope of application is very wide.
2. Japanese brand SPCC - Steel, P-Plate, C-cold, fourth C-common.
3, Germany grade ST12 - ST-steel (Steel), 12-class cold-rolled steel sheet.
