About Donghua Chain Group
Hangzhou Donghua Chain Group was founded in November 1991 and has its headquarters in the Linping National Economic Development Zone in Hangzhou, China. The company develops, manufactures and sells chain drive solutions and produces over 30,000 types in more than 100,000 variants, including precision roller chains, inverted tooth chains, motorcycle and automotive chains (including timing chains), conveyor chains, chains for elevator and escalator applications, agricultural machinery chains, stainless steel chains, chains for heavy engineering as well as sprockets. Products are made predominantly from steel and stainless steel, and for attachment components also with rubber attributes. The products serve customers in industries such as automotive, motorcycle, agricultural machinery, metallurgy, bulk materials, oil and gas, construction machinery, elevator construction, environmental technology, paper, food, packaging, logistics, rail technology, aerospace, and conveying and mining technology. The company is represented with six production sites in China (Hangzhou, Xinghua, Changzhou), Japan (Ishikawa), Germany (Wuppertal) and Poland (Znin) and, in addition to six Chinese subsidiaries, maintains nine foreign subsidiaries, including Donghua Netherlands and Donghua USA. It is certified as a national technology center enterprise and leading Chinese industrial company and offers development, manufacturing, distribution and market service from a single source.
