Steel manufacturers are companies that produce steel, a strong and durable metal used in various industries. They transform raw materials like iron ore, coal, and limestone into steel through processes such as smelting and refining. The resulting steel can be shaped into different forms, including sheets, beams, and rods, which are essential for construction, automotive, and machinery applications. These manufacturers play a crucial role in the global economy, supplying materials for infrastructure projects and everyday products. Major steel manufacturers include ArcelorMittal, Nippon Steel, and China Baowu Steel Group, which operate large facilities and employ advanced technologies to enhance production efficiency and sustainability.
