ISO9001 Construction Mechanical Steel Bar Splice:
Introduction of bar splice
(1)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 12mm to 40mm).
(2)It can meet the requirement of two rebar with different diameter.
(3)Handy operation and quick link.
Upset forging parallel thread machine
The upset forging parallel thread machine contains one rebar threading machine(GZL-45) and one upset forging machine(GD-150), they work together with couplers for the connection of rebar whose diameter is between 12mm and 40mm.
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.
1, 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, economize energy source and bar material.

(1)TEST: 100% BAR BREAK;
(2)THE PARAMETER IS ALSO CUSTOMIZED;Competitive 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.4.Manufactured under strict quality assurance plan ISO 9001 and Technical Approval TAC-1335.this type of rebar coupler is matching rebar thread processed by rib peeling thread rolling machine.6. reliable quality, the raw material origin and production batch can be traced.7. full implemention according to ISO9001:2000 quality management system.
