Detailed Product Description

The coupling sleeves can connect the reinforcing bars with different diameters and also with different screw thread directions. The coupling sleeves are divided into 9 categories according to the out diameter of the steel bars.

Superstrong: it has high intensity and reliable  and steadily connetion. Connect intensity reach 1 grade piecing requirement of performance in "whether reinforcing bar machinery connect common technical regulation", JGJ107-2003 of sector standard, . It is no smaller than actual tensile strenth of reinforcing bar or 1.10 times of the standard value of tensile strength of reinforcing bar connected to connect tensile strength.
