About us

Company details

Duferco was established in 1979 by Bruno Bolfo, Chairman of the Board, and a group of other steel professionals to exploit the advantages of "emerging markets" in steel production. At its inception, Duferco was based in New York and Sao Paulo, Brazil. The Company, through its relationship with local steel producers, quickly became the leading independent exporter of Brazilian steel throughout the world. Duferco's growth and profitability was based upon a close relationship with key Brazilian producers (Cosipa/CSN/CST/Acominas and Usiminas) and the establishment of a small sales network, predominately in the US and in the Far East (Duferco's first office in the Far East was opened in Thailandin 1980).
