At the age of 29, José Correia Fernandes founded the metalworking company “O Setenta” on Conselheiro Lobato Street in Braga, operating as a sole trader. It began as a small garage with just a few machines.
Over the years, we have invested in both technical and production capacity, through the acquisition of new equipment and the training of our human resources.
Along the way, we operated in facilities in Nogueira and Lomar, but since 2002 we’ve been based in the Adaúfe Industrial Park.
