Cold rolling means at room temperature, after cold drawing, cold, cold drawn, such as the processing of cold steel or steel into various types of steel. Advantages: forming speed, high output, and does not damage the coating, can be made into a variety of cross-sectional form, needs to adapt to the conditions of use; cold-rolled steel to produce a lot of plastic deformation, thereby increasing the yield of steel points. Disadvantages: 1. Although the molding process has not been seamless steel pickling hot plastic compression, but there are still residual stress in the cross-section of global and local buckling resistance of the steel will inevitably have an impact; 2. cold-rolled steel style is generally open section seamless steel pickling, so that the free section of low torsional stiffness. When flexural prone to twisting when pressure is prone to bending-torsional buckling, torsional performance is poor; 3. cold-formed steel wall thickness smaller, in the corner of the plate convergence and no thicker to withstand localized concentrated load capacity is weak.
