Offices
From 1986 TETRAGON is located in Thessaloniki. The activities of the company in a wide spectrum of clients and projects and its development, marked by its participation in HELEXPRO, led to the creation of offices in Athens in 2004 and in the International Exhibition Center of HELEXPO in Thessaloniki in 2006. In 2007 the company acquired its own storage facilities in Sindos, Thessaloniki.
