Product Description

Principle:

First, use the machine to make the thread on the end of rebar .

Second, use the polygon rebar coupler(coupler) to link the two ends of rebar.             

Advantages:

1,The  polygon couplercoupler) can be used to link rebar whose diamter is between *2mm and *0mm.

2,The tensile strength of the  polygon coupler(coupler) can be 1.1 times of the steel bars.   

3,Especially, the exceed strength(special material) coupler's tensile strength is more than **0Mpa

Characteristics:

The surface of these rebar coupler are polygonal, such as hexagon, octagon, decagon, dodecagon,etc, not just round.
