Product Description
1. Product Description
Upset forging parallel thread steel bar coupler can connect the deformed bars of FE500, FE550, FE600, ASTMA615 or other similar ones in the diameter range of 12~50mm. It can make sure 100% Bar Break Performance, it can connect steel bar diameter from 12mm to 40mm.



2. Working Principle: 

First, we use GD-150 to forging the end of rebar. 
Second, we use the GZL-45 to threading the end of rebar. 
Third, we use the coupler to link the two ends of rebar. 

3. Advantages: 
1). The connection has the high tensile strength. The tensile strength of connector should equal to or not less than 1.1 times of steel bar itself. And the strength reach Grade I (reach 1.1 times of material's) and 100% exerted Grade II.  

2). There are many types of couplers, are suitable to used in reinforcing steel bar cage, bend reinforcing steel bar.  

3). High efficiency, easy operation and high speed connection, the processing of the reinforcing bar end is factory operation, it wont occupy the time of construction, the local connection can save a lot of time. Upset forging and threading one coupler only needs no more than one minute 

4). Environmental protection, the processing of the reinforcing bar and the site operation is safe and reliable without noise, open flame and soot. Economize energy source and material, economy profit 

Customer's special demand is available. For example, 38mm, 50mm.

6. 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
JGJ107-2003, JG171-2005. 
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. 
 
7. FAQ
1. How can I know the quality of JBCZ rebar coupler?
We can send you FREE SAMPLE to do test, or you can send us your rebar, we link it with our rebar coupler, then send back to you, if the test result is bad, we will pay you for the courier charges.
2. Where is your company?
