Features of epoxy coated rebar coupler

Anti-rust, anti-corrosion, extend projects service time efficiently

1. The Hangzhou Bay Crossing Sea Bridge is one of the earliest projects apply epoxy rebar connection in China. The bridge is totally 36 kilometers long. Rebars immersing in seawater for long time will reduce bridge service life. Therefore, this project accepted the design that coat epoxy on rebars. According to the special condition, JBCZ customized cold extrusion press coupler and straight thread coupler for this project.

2.The color of epoxy coated coupler can be customized according to clients’ requests, usually there are two types with blue and green.
