Cold extrusion press connection technology is a kind of screw-less,equal strength connection technology. And because of the good fatigue resistance,it is widely used in bridge construction. Our cold extrusion press system performs standards of JGJ107-2003 General technical specification for mechanical splicing of bars and JGJ108-96 Specification for Pressed Sleeve Splicing of Ribbed Steel Bars.
 
Detailed Product Description 
Features:
1) BS4449 REBAR SCREWLESS COUPLER works together with cold extrusion press machine. Can be used for the connection of rebar whose diameter is between 16mm and 40mm. 
2) Includes two types:YJ650 and YJ800.YJ650 can be used to connect steel bar of dia 16mm-32mm. YJ800 can be used to connect steel bar of dia 36mm-40mm..
3) No flammable gases, not affected by rainy or cold weather,easy to operate.
4) It is able to connect changed steel bars in different diameters
5) Saves 80% connector steel consumption
6) Can connect steel bar ,one of whose ends is fixed in concrete;
7) Because of the good fatigue resistance of the joint, it is very suitable for bridge construction;
