P.S.: Non-standard steel pipes are an economical cross-sectional profile material, widely used in construction, automotive, and large-scale steel structure fields. According to relevant literature, in developed countries, the demand for non-standard profiles accounts for 5% of the total steel production annually, particularly square and 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 non-standard steel pipes in the construction sector has been recognized. With the rapid development of China's economic construction and the acceleration of urbanization, the prospects for non-standard steel pipes are promising. Currently, the main production methods for non-standard steel pipes in China are cold bending forming welding and cold drawing.
The company adheres to the corporate philosophy of "Innovation Realizes Value," continuously meeting the diverse needs of our extensive customer base.
