Product Description
As an important parallel thread connection technology, the upset forging parallel thread connection technology possesses 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 or ASTM 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.

12.No staggering of spliced bars required.

4. What makes us successful 
A. Shorten your engineering period -- the two rebars can be connected within 35 seconds; 
B. Catch the highest quality -- 100% broken rebars, no safty worrying, can past any safty quality

C. Save rebars -- give up weld and colligation rather than our connecting methods, can save many rebars materials. 

5.Why choose JBCZ 
1, High strength: the strength reach Grade I , 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 

2 ,Wide working range: adaptable for Φ12mm-Φ50mm same diameter, different diameter, bending, new and old,
advance covered up rebar of GB 1499 , BS 4449 , ASTM A615 or
 ASTM A706 standard.

3,High efficiency: upset forging and threading one joint only needs no more than one minute, and handy operation
and quick link.
4,Environmental protection and economy profit: no
environment pollution, can work all day, not affected by
weather, economize energy source and bar material.
