Высокопрочные прямоугольные бесшовные трубы из нержавеющей стали и легированных марок. Точные размеры, коррозионная стойкость, идеальное решение для конструкционных, механических и архитектурных применений.
As one of the top rectangular seamless tube manufacturers in China, we provide premium-grade seamless tubing solutions designed for structural integrity, corrosion resistance, and high mechanical performance. These tubes are widely used in engineering frameworks, architectural supports, vehicle manufacturing, and heavy-duty machinery.
Our rectangular seamless tubes are produced using hot-rolled or cold-drawn processes to ensure uniform wall thickness, tight tolerances, and smooth surfaces. We offer custom fabrication options including exact size, wall thickness, and surface finish according to your application.
All products comply with international standards such as ASTM, EN, and ISO, and are available in materials like 304/316 stainless steel, duplex 2205, and high-nickel alloys for specialized environments.
