About Us

The chain & sprocket kit makes for a simple but extremely effective combination. These components are an integral part of logistic equipment, material handling equipment, and other types of automated mechanical assemblies. Renowned for durability and dependability, DONGWU can provide prospective customers with outstanding chain transmission solutions. 


As an experienced Chinese transmission chain manufacturer, we offer a wide variety of products including the engineering class roller chain, conveyor chain, elevator chain, drop forged chain, welded steel chain, and sprockets. Also available are specialized chains for sugar and palm oil industries. The strong engineering capacity of DONGWU has assisted many a client with the effective design of unique products. Custom orders with pre-attached drawings and samples can be accommodated. We will formulate corresponding blueprints and await the manufacturing confirmation. Fact-more than 40% of our annual production value can be attributed to custom products with non-standard specifications.


Incorporated in 2000, we have since made significant strides in the improvement of manufacturing techniques. A complete corporate management system allows us to effectively recruit new talents while developing new types of engineering and conveyor chains. Through progressive advancement, we have emerged as the leading designer and manufacturer of nonstandard conveyor chains in mainland China. Our excellent reputation has allowed us to gain entry into the National Chain Transmission Standardizing Technology Committee of China.

Our company property spans over 100,000 square meters, of which 30,000 is occupied by newly constructed workshops. We have a dedicated environment protection facility and own more than 400 sets of specialized chain & sprocket production equipment. A safe-production cycle is implemented.
