Lumber EPT Chain
We at EPT mainly offer the 81X and the 3939 series of lumber conveyor chain.The drive chain is especially designed for chain conveyors responsible for lumber conveying. Medium carbon steel is adopted for making the chain components, and advanced heat treatment is implemented to provide the roller chain with high tensile strength and superb abrasion resistance.
Our range of lumber conveyor chain is commonly found in papermaking and lumbering industries.
For more than 20 years, we have focused on custom chains.
For more than 20 years, We have done hundreds of different kinds of industrial chains.
So we have a wealth of custom chain experience.
Here are some of the varieties of the chains.

About us
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 EPT 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-stHangZhourd 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 nonstHangZhourd conveyor chains in mainland China. Our excellent reputation has allowed us to gain entry into the National Chain Transmission StHangZhourdizing Technology Committee of China.
