Steelmaking Legend
Miracle on Yeongil Bay was just the beginning. POSCO had higher aspirations – to become a global No. 1 steelmaker.
While Pohang Steelworks represents our pioneering spirit to transform a forsaken land into an engine of economic development, the construction of Gwangyang Steelworks on a reclaimed land is a testament to our advanced technology and engineering.

Through dedication and passion, POSCO built a steelmaking legend admired by the world.
