rebar coupling

Product Description

rebar coupling:
1. size: can connect rebar size from *2mm to *0mm
2. can connect different size of rebar with one rebar coupling.
3. tensile strength can reach 1.1 times of rebar materials, make sure **0% bar break

Principle:

First, we use GD***0 to forge the end of rebar.

Second, we use the GZL**5 to thread the end of rebar.

Third, we use the bar connector to link the two ends of rebar.          

Advantages:

1,The bar connector can be used to link rebar whose diamter is between *2mm and *0mm;

2,The tensile strength of the 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.
