An integrated mill is a type of steel manufacturing facility where all stage of steel production, from raw material processing to the final finished product, take place within the same facility. These mills typically handle the entire production process, including the smelting of iron ore, refining of steel, and the rolling or shaping of steel into various products like beams, plates, or sheets. Integrated mills are known for their efficiency and ability to produce large quantities of steel, but they require significant investment in infrastructure and equipment. They also tend to have a larger environmental footprint due to the energy-intensive process involved.
