This system contains one ZLB-09 taper thread machine and couplers, it can be used to connect rebar of HRB335/400, φ 16mm-φ 40mm. The mechanical property of the joint can meet requirements of standard: ACI318-89, ACI359-86, ACI349-89, BS8110-97, DIN1045. Meanwhile, according to requirements of Chinese standard JGJ107-96 and JGJ109-96,
The mechanical property of joint can reach grade II.
1), Can be prepared on or off site;
2), No special skill is required;
3), Easy and rapid to install;
4), It can link bars, which can not be rolled, with a right and left thread coupler.

(1) TEST: 100% BAR BREAK;
(2) THE REBAR COUPLER PARAMETER IS ALSO CUSTOMIZED;
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 test;
C. Save rebars -- give up weld and colligation rather than our connecting methods,
can save many rebars materials.

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.
