Unlike Hot rolling cold rolling has a fast forming speed, high output, and without damaging the coating, it can be made into a variety of cross-sectional forms to meet the needs of utilization conditions; cold rolling can cause large plastic deformations in the steel, thereby improving the steel Yield point.

• 1. Although there is no thermal plastic compression during the forming process, slag stress still exists in the section, which affects the characteristics of the steel group and local buckling.
• 2. The style of cold-rolled steel is usually an open section, which makes the free rotation stiffness of the section low. It is easy to rotate when bent and bend torsional buckling when pressed, and its torsion resistance is poor.
• 3. The wall thickness of cold-rolled steel is small, the corners where the plates are joined are not thickened, and the load is weak.
