Both straight thread rebar coupler and cold extrusion rebar coupler are steel mechanical connection.

The cold extrusion rebar coupler is deformation connection after the sleeve is extruded, and it bite the steel bar through cold plastic deformation to form a plum-blossom toothed sleeve cold-pressed joint. Its strength exceeds that of the base metal. And the reliability and plasticity are better than electric welded joints.

Advantages

(1) The performance of the joint is reliable and it is less affected by environmental and human operating factors.

(2) The operation is simple and easy, and the opertator can take up the operation after fast training.

(3) The speed of deformation connection is 3 to 5 times faster than electric welding and it takes only 3 minutes to connect a 32 joint.
