Steel Wire Technical Center - Hyosung will develop the world's best technology to enrich our everyday lives.

securing world's best technologies and such fundamental technologies as will be future growth engines

The Steel Wire Technical Center, established in 1986 for the development of steel cord and bead wire as well as their production processes, has grown into a research center specializing in steel material.
Having accumulated technology and R&D competency, the Center has recently developed ‘Wafer cutting wire’ used in recyclable energy (solar energy) and IT (semiconductor, LED) industries.
To strengthen R&D in basic technology and core competencies, the Center built a new R&D facility in 2007 followed by the establishment of an overseas technical center to secure technology for ‘Global Excellence.’ The Center has been writing a history of achieving the highest grades of customer satisfaction.
The Steel Wire Technical Center is focused on developing the world’s best technology that customers recognize through creating a stable infrastructure for R&D and securing the newest R&D facilities and skilled researchers. The Center is also investing in developing base technology for new businesses that will be future growth engines.
