Home » About Us

Shanghai Tianyang Steel Tube Company Ltd. is a seamless steel tube manufacturer in China. Our company is a dedicated supplier of quality products, which include our DIN/EN cold drawn and cold rolled seamless steel tube, EP stainless steel tube, hydraulic cylinder honing tube, boiler seamless steel pipe, and more. Tianyang products have a high gloss finish and are extremely anti-corrosive. Our seamless steel pipes are ideal for use in boilers, locomotives, engineering machinery, and injection molding machinery, in addition to many other applications.

To ensure the superior quality of our Bundy tube, boiler seamless steel pipe, EP stainless steel tube, and other seamless steel tube products, we manufacture them with only the best hot rolling steel tube materials, including St35, St37.4, St52, 304, and 316/316L. Meeting the German DIN 2391, European EN10305, and American ASTM269 standards, our tubes are produced using exclusive techniques such as cold drawing, cold rolling, and hot rolling. Our steel tube products have numerous outstanding features including high precision and a high gloss finish. Tianyang products do not leak under high pressure and show no signs of cracking after flattening. Because of these unique features, and the excellent quality of our seamless steel tube products, Tianyang tubes can compete with similar imported products from Germany and Sweden.

To further ensure the quality of our precision seamless steel tubing products, we import much of our testing equipment including our direct-reading spectrometer, pressure blast machine, surface roughness tester, and metallurgical microscope. This state-of-the-art equipment greatly improves our overall productivity, helping us to meet international standards. In addition, we employ over 400 experienced staff members who work diligently to provide our clients with the highest standard DIN/EN cold drawn and cold rolled seamless steel tube, boiler seamless steel pipe, and other seamless steel tubing products. In addition, our testing laboratory is currently working on our application for national testing laboratory accreditation.

At Tianyang, we are committed to improving our quality assurance and quality management systems. In fact, our company has obtained ISO9001:2008 Quality Management System Certification, the Special Equipment Manufacture License of P.R.China, European PED97/23/EC Certification, ISO/TS16949:2009 Automotive Quality Management System Certification, ISO14001:2004 Environment Management System Certification, and the Classification Society Manufacturer Certifications of Italy and France. In addition, in August of 2011, we were certified by the ISO14064-1:2006 Greenhouse Gas International Standard. What's more, our company was the first in the industry to provide green products, which include our green Bundy tube, green boiler seamless steel pipe, as well as our other green products.

Our shaped steel tube, honed tube, and other seamless steel tube products have earned an outstanding reputation in the international market. Currently, we have more than 3000 global customers that include such reputable companies as Trinity Group, Parker Hannifin, China Railway Engineering Corporation, Zoomlion Heavy Industry Science and Technology Co., Ltd., Volvo Group, Mercedes-Benz, General Motors, Sinotruck, Jinan No.2 CNC Machine Tool Co., Ltd., China CNR Corp Ltd., Dalian Shipbuilding Industry Co., Ltd., and the China National Offshore Oil Corporation.

With an annual production capacity of 60,000 tons, Tianyang's headquarters is located in Qianqiao, Fengxian District, Shanghai. Our four factories, covering an area of 80,000 square meters, are located in Shanghai and Zhejiang. In addition to these factories, in 2008 we established the Zhejiang Tianyang Steel Tube Company Ltd. Then, in 2009, we purchased and established the Shanghai Tianyang Steel Tube Southern Factory, 2.4 kilometers from our headquarters. The factory's precision stainless steel pipe production line greatly improves our overall production capacity, which enables us to offer the highest quality stainless steel tubes for our global customers. In 2011, we purchased the Shanghai ZhangShen Metalware Factory, a company with over 20 years of history. This purchase enabled us to vastly decrease the delivery time of our seamless steel tubing products. Furthermore, in order to perfect our local service and technology support, we opened a branch for marketing in Düsseldorf, Germany.
