Being an industry pioneer is a shared work philosophy among all our employees. Our products are marketed throughout major provinces, cities, and regions across the country, and are also exported to Southeast Asia, South America, Europe, and other countries. Non-standard steel tubes are an economical cross-sectional material widely used in construction, automotive, and large-scale steel structures. According to relevant literature, the annual demand for non-standard materials in developed countries accounts for 5% of the total steel production, especially non-standard steel tubes, which have reached a 1:1 ratio with H-beams in the construction industry of developed countries. In China, the successful application of non-standard steel tubes in the construction industry has been recognized. With the rapid development of China's economic construction and the acceleration of urbanization, the prospect of non-standard steel tubes is very promising.
