So far, our products have been selling to global market like Vietnam, India, Russia, Ukraine, South Korea, Singapore, Indonesia, Brunei, Thailand, Malaysia, UAE, Saudi Arabia, Iran, Mexico, America, Brazil, Ghana, etc with the certificates of CE, GOST, ISO9001:2008, SGS, JGJ107-2010.
Machine Function of Dirui Rebar Thread Rolling Machine:
It is mainly applied to peel rebar rib first, then roll parallel thread on rebar end, after that, two threaded rebar sectors could be connected by coupler. It is a necessary machine for rebar joint.
In addition, it is also applied to roll threads on round steel bar, anchor rod, or other equivalent materials.
Machine Advantages of Dirui Rebar Thread Rolling Machine:
1. Both right-handed threads & left-handed threads could be processed with one machine head.
2. Simple operation, reducing workers' labor intensity.
3. Shortening construction period.High processing speed and production efficiency.

Brief introduction
Dirui rebar thread rolling machine DBG-40B is designed for processing parallel threads for rebar mechanical connection in construction. It can process HRB335,HRB400, HR500hot rolled ribbed reinforced bar with diameter 14-40mm. It uses larger machine rac which makes machinemore stable. It adopes famous brander reducer, the machine performance is more superior. It also adopes patented design which aliminates the problem that the rebar thread often becomes bigger, and that the stripping head automatically open.
DBG-40B , as updated type of DBG-40, is our new product developed in 2013. It adds the screw pitch angle mechanism. It is easier t operate, the thread precision is more higher, the conical degree is more smaller, and the thread surface is more smooth.
