Iron & Steel

The Iron & Steel industry manufactures and processes steel, providing foundational materials for construction and manufacturing industries. Through an integrated production system from pig iron production in blast furnaces to steelmaking in converters or electric furnaces and rolling processes, it manufactures diverse steel products including steel plates, steel pipes, shaped steel, and steel bars. It supplies materials that form the foundation of all industries including construction, automotive, shipbuilding, and machinery. This industry develops high-performance steel materials suited to specific applications, such as high-strength steel, corrosion-resistant steel, and high-tensile steel plates. It provides products that meet societal needs, including achieving both vehicle weight reduction and collision safety, improving seismic resistance of buildings, and enhancing energy efficiency. Through improvements in quality control and production technology, it achieves high dimensional accuracy and quality stability. Environmental response is also an important issue, promoting initiatives toward realizing green steel through the development of energy-saving manufacturing processes, scrap recycling, and introduction of CO2 emission reduction technologies. The industry also focuses on developing innovative steelmaking technologies such as hydrogen reduction ironmaking.
