Cold Extrusion Thread Coupler

Made of high quality 20# carbon structural steel, the cold extrusion thread coupler enjoys high strength and it is able to connect reinforcing bars with the diameter of 16 to 40 mm. With no limitations on the type, composition, or weldability of steel bars, this rebar connector is widely used in bridge construction.

Cold Extrusion Connection
Firstly, the reinforcing bars to be connected are inserted into the cold extrusion thread coupler. Then, the coupler is squeezed by the crushing clamp to deform plastically and connect tightly with the ribbed rebars.

Features
1. With stable and reliable quality, this cold extrusion thread coupler complies with ISO standard and Chinese standard JGJ107-2010. Quality check can be completed with ordinary measuring tools or just visually.

2. Using the rebar coupler to connect rebars is easy and fast to conduct. There is no open flame during the operation, which ensures high safety. The operation process is also eco-friendly, as there is no pollution caused.

3. Connecting steel bars with thread coupler saves energy and materials. Specifically, the steel consumption is reduced by 80% when compared with that of overlapping connection.
