Remark:  we can also make other specification parallel thread rebar couplers according request.

 

Type and Application:

1. Standard type: used to splice rebars in normal condition.

2. Left-handed and right-handed type: used in condition that the two continuation bars cannot be rotated.

3. Reducing type: used to connect rebars of different diameters.

 

Relate Test:

1.Tensile Strength=1.1*Tensile Strength of Rebar (Usually more than 600Mpa)

2.Fatigue Test: After 2 million times of fatigue strength test, connection is in good condition

We have done official tensile test in Korea, Russia, Saudi Arabia, Vietnam,etc.
