Product Description
It can connect the deformed bars of HRB335, HRB400, FE500, FE550, FE600, ASTMA615 or other similar in the diameter ranging from 12~40 mm.

1. The connection has the high tensile strength. The tensile strength of connector should be 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% rebar break.

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 need 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.

Except for the standard rebar connectors, we have high tensile strength and yield point ones. It can be customized.

To work with this parallel thread rebar coupler, we have upset forging parallel thread machines.
Upset forging parallel thread machine
DescriptionThe upset forging parallel thread machine contains one rebar threading machine(GZL-45) and one upset forging machine(GD-150) and an oil pump. They work together with couplers for the connection of rebar whose diameter is between 12mm and 40mm.
Working PrincipleFirst, 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.
Advantages1. Adopts upset forging parallel thread connection technology;
2. Wide working range: Adaptable for 12mm-40mm 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 strength: Stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar's specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003, JG171-2005;
4. High efficiency: Upset forging and threading one joint only needs no more than one minute, and handy operation and quick link;
5. Environmental protection and economy profit: no envirement pullution; can work all day, not affected by weather, economizing energy source and bar material.
Other similar systems:
We have reducing couplers of upset forging parallel thread connection system and rib peeling roll stamping connection system, they can be used for the connection of rebars with different diameter (from 16mm to 40mm).
