Zhongbo Railway Fastening Company is a leading Chinese manufacturer of rail fastening and rail joint bar. Zhongbo, as a specialized rail fastener manufacturer, provides a complete line of products, including rail fastening, anchor, rail joint, rail clip, rail screw, anchor bolt, rail clamp plate, rail fishplate, and fishplate bolt for connecting rail tracks. We also make rail fastenings for crane rail and elevator guide rail, along with other related products. We manufacture according to GB/TB (Chinese national standards and railway standards), AREA, UIC, BS, DIN, ASTM, and AS standards. Our products are mainly made through hot forging. The threads of rail screw spikes are made by hot rolling with special threading machines. We produce metric threads, BS, BSW, TR thread, or round threads. Our high strength bolts come in different specifications of Class 4.8, 4.6, 5.6, 5.8, 6.8, 8.8, 10.9, and 12.9. A variety of non-standard fastening is also available. We can customize our products using customer drawings or samples as well.

Our products are used in both main lines and branch lines, both for maintenance of old railroads and construction of new ones. Due to reliable performance, our exceptional rail products are exported to such places as North America, South America, Australia, Europe, and Southeast Asia.

Zhongbo was founded in 2006, and in 2008, we moved to Taicang City, enabling us to accommodate increased market demand for our products in our 20,000 square meter factory. New buildings and workshops have been built to make our total capacity over five times larger than before. In 2009, our registered capital increased to RMB thirty million, and company ownership changed from privately-held to shareholder-owned. Also since 2009, we have been supplying high strength anchor screw for China's high speed railroad. We have received large orders from both domestic and overseas customers.

We strictly apply quality management in line with ISO2008 standards throughout the manufacturing process, from raw materials to finished products, and from packing to delivery. Each batch of rail fastener is thoroughly inspected and tested before delivery to guarantee that quality of appearance, inside structure, chemical composition, and mechanical properties meet related technical standards. Only products that meet our strict requirements are allowed to be shipped. Customers can feel secure in their purchases because we offer a one year warranty on all our rail fasteners sold.

The staff at Zhongbo looks forward to working with you in the near future.
