About Gerdau

With 123 years of history, Gerdau is the largest Brazilian steel producing company and one of the main suppliers of long steel in the Americas and special steel in the world. In Brazil, it also produces flat steel, as well as iron ore for its own consumption. In addition, it has a new business division, Gerdau Next, with the aim of undertaking operations in segments adjacent to steel. With the purpose of empowering people who build the future, the company is present in several countries and has more than 30 thousand direct employees in all its operations. The largest recycler in Latin America, Gerdau uses scrap as an important raw material: 71% of the steel it produces is made from this material. Every year, 11 million tons of scrap are transformed into various steel products. The company is also the largest producer of charcoal in the world, with more than 250 thousand hectares of forestry in the state of Minas Gerais. As a result of its sustainable production matrix, Gerdau currently has one of the lowest average greenhouse gas emissions (CO₂e), at 0.86 t of CO₂e per ton of steel, which represents approximately half the global average sector, 1.91 t of CO₂e per ton of steel (worldsteel). For 2031, Gerdau's goal is to reduce carbon emissions to 0.82 t of CO₂e per ton of steel. Gerdau shares are listed on the São Paulo (B3) and New York (NYSE) stock exchanges.
