STEJASA was set up in 1974 in Madrid (Spain) as a subsidiary of STEJASA in Germany. In 1990 STEJASA was bought by Juan Manuel Victorio and Julio Molina (members of the BoD at that time) to his former owners. Since then Juan Manuel Victorio has been leading STEJASA through a fantastic journey. In 1993, we decide to undertake our international expansion through the French market. By 1998 we had a 90% market share over the border! In 1997 we decided to move to Italy. Thanks to our partner NME S.r.l Italy has been one of our key markets since then.
