Kuplör
Cold Extrusion Technology
Usage
Cold Extrusion coupler is a kind of flexible connection designed to splice bars in location at site, the coupler is squeezed by the clamp to deform plastically and connect tightly with the rebars.
Usage
The test result of this kind of connection can guarantee the tensile strength of connection specimen is no less than 125% of the normal yield strength of rebar.
