Product materials: carbon steel grades include Q195, Q235, Q345, etc., seamless pipe grades include: 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 40Cr, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, 45Mn2, etc. Stainless steel grades include SUS201, 202, 302, 304, 316, 304L, 316L, 321, etc.


Our factory products are mainly used in construction, furniture, zinc steel fences, automobiles, refrigerators, air conditioners, highway guardrails, steel structures, etc. The company's square tube production range is 10mm*10mm to 1000mm*1000mm; the rectangular tube production range is 10mm*20mm to 1000mm*900mm, with wall thickness ranging from 0.2mm to 100mm. Currently, the company has a domestic large-scale cold bending hollow section steel production line with dimensions of 800×800×30mm, as well as a 1600mm slitting line. The F200 model utilizes international direct square and rectangular tube technology, capable of producing square tubes from 10mm*10mm to 1000×1000mm; rectangular tubes from 10mm*20mm to 800×1200mm; wall thickness from 0.2mm to 100mm, with an annual output of 400,000 tons. We also offer custom-made grooved tubes, flat round tubes, triangular tubes, hexagonal tubes, octagonal tubes, trapezoidal steel tubes, conical steel tubes, and more. Our products are widely used in steel structures, machinery manufacturing, engineering, automotive manufacturing, shipbuilding, power, and many other industries.


Our entire staff is committed to the principle of quality first and credibility, dedicated to providing excellent service to our customers. We operate under the effective model of the ISO9001-2000 international quality system to serve the special-shaped steel pipe market. Being an industry leader and explorer is a shared work philosophy among all our employees. Our products are marketed across various provinces, municipalities, and regions in China, and are also exported to Southeast Asia, South America, Europe, and other countries. 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, the annual demand for special-shaped materials in developed countries accounts for 5% of the total steel volume, especially in the construction industry of developed countries, where the usage of special-shaped steel pipes has reached a 1:1 ratio with H-beams. In China, the successful application of special-shaped steel pipes in the construction industry has been recognized.
