WebIt is widely understood that when a cold formed hollow section is produced, stresses are put into the steel in the shaping and forming process. This differentially hardens the steel, particularly at the corners and along the weld-line, which reduces ductility and produces points of weakness in the structure along which cracks could form (Figure 1).
