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.
