As a round steel link chain manufacturer for 30 years, our factory has been staying with and serving the very important period of Chinese chain making industry evolution catering for mining (coal mine in particular), heavy lifting, and industrial conveying requirements on high strength round steel link chains. We don’t stop at being the leading round link chain manufacturer in China (with annual supply over 10,000T), but stick to non-stopping creation and innovation.
