The Masteel New Area Project with a total investment of more than 25 billion yuan was fully completed in 2007, forming a supporting production scale of180,000 tons of steel. Masteel has three major sectors: mineral resources industry, main steel industry and non-steel industry. Among them, the mineral resources industry is dominated by iron ore, and its business is concentrated in mining companies. It has jurisdiction over Nanshan Mine, Gushan Mine, Taochong Mine, Luohe Mine and Zhangzhuang Mine, and now has an annual iron ore production capacity of100000 tons. The main business of iron and steel is concentrated in Masteel, mainly engaged in ferrous metal smelting, calendering and product sales. It has world-class production lines such as cold-rolled plate, galvanized plate, color-coated plate, silicon steel, high-speed wire rod, H-beam and wheel (tire), forming a unique product structure of "plate, shape, line and wheel", with the ratio of plate to belt exceeding 50%; Non-steel industries involve finance, environmental protection, logistics, trade, engineering design, steel structure, equipment manufacturing and installation, technical consultation and labor services. On this basis, Maanshan Iron & Steel Co., Ltd. will continue to promote the structural adjustment of the main steel industry, focusing on the product structure adjustment, and strive to become a modern large-scale enterprise group with strong international competitiveness as soon as possible.
