Specifications Threaded coupling is made of 45#high quality carbon steel with diameter from 16mm to 40mm.

Rebar coupler is applied to reinforced concrete construction in various kinds of construction projects. It is a technical product highly pushed by National and District Construction Department. It is a new way for mechanical connection with high quality and efficiency. Easy operation, saving time, can not be affected by weather. With the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part.
