NPG 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.
Our chain factory started 30 years ago making low grade steel chain for marine and decoration purpose, while accumulating experience,personnel & technology about chain material,chain welding,chain heat-treatment & chain application in various industries. Chain grades were covering Grade 30, Grade 43 and up to Grade 70. This was primarily due to then Chinese steel mill capacity insufficiency for developing higher strength alloy steel,but with carbon steel only for chain making industry.
