With the emergence of high-rise building, large-span space and special structures, the application of building rebar is developed towards big diameter, dense and high strength.

The traditional rebar splicing technology such as welding and lapped splicing can not meet the requirements commendably in strength and saving cost. In this condition, as a new rebar connection technology, parallel thread connection technology, especially the upset forging parallel thread connection technology is now more and more adopted in projects.

As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:

1.Wide working range: adaptable for Φ12mm-Φ40mm same diameter, different diameter,bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 orASTM A706, ACI318,BS 8110, DIN 1045, standard.

2.High strength: stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar).It can satisfy the requirements stipulated in the Chinese standard JGJ107-2010,JG171-2005.

3.No reduction of the bar cross section area.

4.Allows full ductile elongation of bars.

5.Easy installation, no torque wrench required.

6.One standard coupler for all splicing requirements (Standard/Position).

7.Manufactured under strict quality assurance plan, ISO 9001 and ASME certified.

8.Full traceability of material origin and production batch.

9.Type 2 coupler suitable for seismic areas.

10.Tested under reverse-cyclic conditions.

11.Solves bar congestion problems.
