Hansung Precision Company was established in 1989, and since its birth, we have been making significant contributions to national development. We develop and manufacture mechanical splicing of reinforcement bars that increase stability, lock bolts for that secure base rocks for the numerous tunnels of Korea, and super fibers for reinforcing concrete.

After ceaseless and unhindered research, development and efforts of our entire staff, we were the first company in Korea to develop the HS-BAR, which is a swelling screw joint reinforcement bar. The HS-Bar makes possible conservation of iron resources, enhancement of construction quality, and is realizing precision safety construction.

In addition, through research and development of lock bolts for NATM tunnels, we were able to develop the ring lock nut and received a KT Mark from Korea Academy of Science and Technology. The Korea's first technology of forming a screw by swelling both ends of the reinforcement bar was recognized for its technology and quality. It received the NT Mark from the Small Medium Business Association, the EM Mark from the National Institute of Technology and Quality.

Also, as the result of 5 years of research and efforts, rolling type bar splicing was developed, and in order to improve precision safety construction of the 21st century Korea and to become a corporation that can be trusted by our clients through the highest level of quality, a factory process management system that can minimize losses was installed and a new reinforcement processing factory was constructed.

We will continue to do our best in striving for enhancement of precision safety construction, and by developing technologies of superior quality, we will become a corporation that provides reliability and trust to our clients. Furthermore, we at Hansung extend our deep appreciation and gratitude to those who have continued to support and encourage for our success.
