Non-standard steel pipes are an economical cross-sectional material, widely used in construction, automotive, and large-scale steel structures. According to relevant literature, in developed countries, the demand for non-standard materials accounts for 5% of the total steel output each year, and particularly, the usage of non-standard steel pipes in the construction industry of developed countries has reached a 1:1 ratio with H-shaped steel. In China, the successful application of non-standard 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 non-standard steel pipes will continue to improve.
