Founded in 1966 and headquartered in Changwon-si, South Korea, the company changed its name from BNG Steel Co., Ltd. to Hyundai Bng Steel Co., Ltd. in March 2011 following integration with the Hyundai Motor Group, which expanded its production capabilities through facility upgrades such as the #5 Z-mill, #3 bright annealing line, and an ultra-thin sheet metal plant in Changwon. Recent operational enhancements include a major modernization of its 20-high reversing mill by ANDRITZ Sundwig, featuring new control electronics, main drives, automatic thickness and shape controls, and hydraulic screw-down systems that boosted production tonnage by 10% and enabled thinner, higher-quality strips for new markets. As part of the Hyundai Motor Group, it supplies specialized stainless steel for automotive applications and benefits from group-wide strategic shifts toward low-carbon steel and advanced materials development.
