Tianjin Yuantai Derun Pipe Manufacturing Group Co., Ltd., established in March 2002 and stemmed from the Tianjin Yuantai Industrial and Trading Co., Ltd, is located in the biggest pipes-manufacturing base—Daqiuzhuang industrial zone in Jinghai Tianjin which is close to the China National Highway 104 and 205 and is only 40 km far away from the Tianjin Xingang Port. The excellent geographical location supports the convenience to both inland and outland transportation.
As a professional manufacturer of hollow sections, ERW steel pipe, galvanized square tube, galvanized steel pipe and spiral pipe in China, Yuantai Derun stands among "The top 500 manufacturing enterprises” in China, with an annual output reaching 5 million tons.
In the contemporary industrial landscape, Rectangular Steel Pipes (RSP) have transitioned from simple structural components to high-engineered assets essential for complex mechanical systems. The global market for rectangular hollow sections is witnessing a significant surge, driven by the rapid urbanization in emerging economies and the modernization of industrial facilities in developed nations.
Technological advancements in ERW (Electric Resistance Welding) and JCOE LSAW manufacturing processes have allowed for tighter tolerances and higher strength-to-weight ratios. This efficiency is why rectangular pipes are preferred over traditional I-beams or channels in many applications—they offer superior torsional resistance and a cleaner aesthetic for exposed structural designs.
Yuantai Derun operates 51 black ERW pipe lines and 10 galvanized lines, catering to a massive global demand for standardized and custom rectangular sections.
With a registered fund of USD 65 million and fixed assets of USD 3.5 billion, our group ensures stability and large-scale supply chain reliability.
Full compliance with ASTM A500/501, JIS G3466, EN10219, EN10210, and AS1163 ensures our products are ready for international infrastructure projects.
In the mechanical sector, Rectangular Steel Pipes serve as the primary chassis for heavy machinery, CNC equipment, and automated assembly lines. The flat surfaces of the rectangular profile simplify the mounting of sensors, gearboxes, and robotic arms. Unlike round tubes, the flat faces allow for easier bolting and welding of bracketry without the need for complex saddle cuts.
Modern architecture utilizes rectangular sections for glass curtain wall supports, airport terminals, and stadium roofs. Their geometric symmetry provides a balanced aesthetic while maintaining high load-bearing capacity. Yuantai’s JCOE LSAW pipe technology enables the creation of large-diameter sections that can withstand extreme environmental stresses.
The renewable energy sector is a burgeoning market for galvanized rectangular tubes. They are used extensively in solar tracking systems and wind turbine internal platforms. The hot-dip galvanized coating provides decades of corrosion resistance in harsh outdoor environments, making them the most cost-effective choice for long-term energy projects.
From the frames of heavy-duty trailers to the racking systems in automated warehouses (AS/RS), rectangular pipes provide the necessary rigidity to handle dynamic loads. Their predictable performance under compression and tension makes them vital for safety-critical transportation components.
Yuantai Derun is at the forefront of these trends, continuously investing in R&D to provide solutions that are not just pipes, but integrated engineering components.
Yuantai Derun has 7 mills including 59 production lines of black ERW pipe, 10 production lines of galvanized pipe and 3 production lines of spiral welding pipe. Our capabilities are unmatched in the industry:
