rebar coupler

We have three kinds of rebar coupler:I.Upset forgingparallel thread rebar coupler (Upset forging parallel thread system):This kink of coupler is of straight screw thread.Thecoupler can link rebarwhosediameter is between 12 mm and 40mm.The tensile strength of thestandard coupler can be more than 627Mpa.The tensile strength of the fortified coupler can reach 800MPA to 1000MPA.This system is widely used at home and abroad. The tensile strength of this kind of coupler is high and the capability is very nice.We have CE certificate for this series.II. Rib peeling roll stamping rebar coupler (Rib peeling roll stampingsystem):The coupler can link the rebar which diameter from 16 mm to 40mm.. The tensile strength of the coupler can be more than 570Mpa.This kind of connection is more rapid and simple and convenient.III. Cold stamping rebar coupler (Cold stamping system):The coupler can link the rebar which diameter from 16 mm to 40mm.Ordinaly speaking, this system is used mainly in the bridge construction. The advantage of this kind of connection is that its resistance is strong.
