Along with the growing automotive industry in the last decade, the demand for automotive tyre is increasing significantly. In year 1997, our company as subsidiary of SEI, Japan, started to produce high quality Bead Wire and Steel Cord to accommodate this increasing demand of tyre in Indonesia and abroad.
