Postscript: Special-shaped steel pipes are an economical cross-sectional material, widely used in construction, automotive, and large-scale steel structure fields. According to relevant literature, in developed countries, the annual demand for special-shaped materials accounts for 5% of the total steel production, especially rectangular steel pipes, which have reached a 1:1 ratio with H-shaped steel in the construction industry in developed countries. In China, the successful application of special-shaped steel pipes in the construction industry has been recognized. With the rapid development of China's economic construction and the acceleration of urbanization, the prospects for special-shaped steel pipes are very promising. Currently, the main production methods for special-shaped steel pipes in China are cold bending forming and welding, as well as cold drawing.
