Parallel thread 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.
1. It has high connecting intension and stable and reliable connecting quality. The intension of the connection has reached the requirement of grade connecting capacity in the Common Regulation of Reinforcing Bar Mechanic Connection. The tensile strength of connector should equal to or not less then 1.10 times of reinforcing bar actual standard tensile strength.
2. It has good endurance resistance and the connector has passed the two million times- Fatigue Tests of industry provision.
3. Saving materials: Take the example of 40mm splicing coupler, extrusion sleeves is 4kg, the straight screw thread Coupling sleeves in only 1.1kg. The weight of straight screw thread takes 25% of extrusion sleeves but the connector capability is the same as the extrusion sleeves.
