Based on our world-class steel and energy plant construction competency, we are providing Total Solutions to the Plant business.
POSCO E&C accumulated its top-tier steel plant construction technology after taking in charge of steel plant construction projects in Pohang and Gwangyang for POSCO, the world’s most competitive steel-making company. Since then, we became one of the world-renowned companies by successfully accomplishing mega projects with world-class steel plants, including Brazil CSP Steel Plant and Indonesia Integrated Steel Mill.
In 2006, POSCO E&C was the first Korean E&C company to enter the power plant market of Central and South America. We contributed to the supply of insufficient energy as well as the economic growth and social development of countries including Chile, Peru, and Panama. Consequently, we diversified our business areas from steel and energy to chemical engineering and industrial plants.
Moreover, POSCO E&C realizes qualitative growth by actively carrying out projects for environmental, social, and governance (ESG) management, such as Hydrogen and Renewable Energy businesses.
