Permasteelisa was first established in 1973 in Italy (originally with the name of ISA), genius of its visionary founder who had the future in his eyes.
The Company's growth and the international expansion of its activities in Italy and abroad starting in the mid-eighties have today led the Permasteelisa Group to be a worldwide leading Contractor in engineering, project management, manufacturing and installation of architectural envelopes and interior systems.

In January 2001 Gartner became a 100 % subsidiary of Permasteelisa S.p.A., in Vittorio Veneto, Treviso/Italy. At the end of 2001 Josef Gartner GmbH & Co KG changed to Josef Gartner GmbH.
