Why Choose Us


Our company has also jointly designed "ZTF" forming method with rotating vertical roller and direct forming method with Welded Pipe Equipment Company. The multi-functional cold-formed series welded pipe unit can produce both round pipes and square and rectangular pipes, as well as cold-formed steel pipes, truly realizing "one machine for multiple purposes".

In 2014, our company and the welding pipe equipment company also innovated and developed a new direct square forming process, which realized the automatic adjustment of the whole line of mold rolls when changing specifications, greatly reducing the labor intensity of workers and improving the work efficiency.

The company's products have obtained 13 utility model patents. The special raw materials, high chromium alloy and ZJD1, have increased the high strength and wear resistance of the roller. The unique mirror polishing technology has created a bright product finish.



The company strictly implements the ISO9000-2001 quality system document, follows the management idea of "showing quality in detail and determining success or failure in every bit", pays attention to the control of the whole process of product realization, and ensures that the quality and construction period meet the needs of customers. Professional commissioning engineers provide users with reliable terminal services. It has 8 domestic advanced fanak system precision CNC lathes, 13 heat treatment equipment such as vacuum quenching furnace, 180kW non oxidation heating furnace, and 10 wire cutting equipment, etc., to meet the manufacturing requirements of precision rolls with diameters below 1200 mm.

Advanced technology, strong processing strength and perfect after-sales service system have cast the excellent quality of "Zhongjie" roll. Our company has always provided comprehensive technical services and technical agreements in roll design, adjustment, processing and repair.
