The ArcelorMittal Piracicaba steel plant was originally founded in 1955 under the name Dedini Siderúrgica S.A. (Dedini Steelworks).[2] In 1994 the Companhia Siderúrgica Belgo-Mineira (Belgo) acquired a 49% stake in the plant[2][3], and three years later Belgo assumed full ownership[2], increasing the plant's annual production from 300,000 to 500,000 tons. In 2004, a second expansion doubled the plant's capacity to more than one million tons per annum[4] with the installation of a new Danieli electric arc furnace and ladle furnace to replace the plant's original furnaces.[5] A series of mergers between 2001 and 2006 resulted in the plant becoming part of the ArcelorMittal group .[4]

The Piracicaba plant is part of ArcelorMittal Brasil's Aços Longos (long steel) division, together with the ArcelorMittal Monlevade steel plant and the ArcelorMittal Juiz de Fora steel plant.[6] ArcelorMittal Piracicaba is Brazil's leading producer of rebar for civil construction[7], and also manufactures specialty products such as threaded rods.[4]
