GREETING
Thank you for visiting
Hansung Precision.
We are grateful to everyone whose support has brought Hansung Precision to where it is today. We know that a company survives and grows only through the choice and trust of its customers, and we work every day with that in mind.
Since our founding in 1981 we have manufactured mechanical rebar splicing systems, rock bolts for NATM tunnel rock support and steel fibre for concrete reinforcement, contributing to safer building and civil engineering works. Through persistent research our engineers developed HS-BAR, Korea's first upset-forged (swaged) and roll-threaded rebar splice, which saves reinforcing steel, improves workability and enables precise, safe construction.
We also developed rock bolts for NATM tunnels; our ring-nut design earned the Minister of Science and Technology's KT New Technology mark. Our process of upsetting both bar ends before thread-forming — a first in Korea — received New Technology designation from the Ministry of Construction and Transportation, the NT mark from the Small and Medium Business Administration and the EM mark from the National Institute of Technology and Quality. We are ISO 9001 certified to secure quality and customer service.
In a rapidly changing market we strengthen our competitiveness through sound, substance-first management, aiming to be a company that brings satisfaction and value to its customers. All of us at Hansung promise to meet your requirements with the best quality and service, and to do our utmost to advance the construction industry.
In Hwan Roh, CEO, and all employees of Hansung Precision Ind. Co., Ltd.
