Cold extrusion Rebar Coupler
Cold extruded steel bar joints do not require welding or threading, and are suitable for connecting steel bars of various diameters, especially performing well in large concrete structure projects such as high-rise buildings, bridges, and subways.
Cold Extrusion Rebar Coupler For Concrete Construction Rebar Splicing Coupler
Cold extrusion Rebar Coupler
Cold extruded steel bar joints can effectively transmit the axial tension and pressure of steel bars, with high connection strength, stable performance, and simple and fast construction operation. It is not affected by environmental temperature and can significantly shorten the construction period. At the same time, it avoids the fire hazards caused by welding and material loss in thread processing

Cold Extrusion Rebar Coupler Features
High strength and reliability: excellent static performance, damage usually occurs in the steel bar body rather than the connection. Cold extrusion is a room temperature process, which can avoid metallographic changes or strength reduction caused by welding
Permanent connection: cannot be disassembled after extrusion, it is an irreversible connection method
Strong environmental adaptability: fatigue resistance, vibration resistance, suitable for dynamic load structures (such as bridges, high-speed railways)
Professional equipment required: hydraulic pliers or extruders are required to apply radial pressure to the sleeve during use, so that the sleeve is tightly engaged with the steel bar after plastic deformation
