IBS Upset forging threaded coupler:

Upset threaded couplers are also threaded coupler splices, the difference here is mainly in the processing of the steel rebar thread.
The rebar is being cold forged before threading with a special pressing machine to enlarge the diameter of the rebar, then the threading of the rebar will be carried out, we at Bartek Systems we apply different methods for the threading depending on the application and project, for some application we use thread cutting machine while for some other projects we roll the threads.
