The activity of GELLI was established by Gianfranco Gelli in 1976 when he started his own homonymous one-man-business as professional welder. Over the course of the years his firm increased both its size and the offered services.
Actually GELLI works on an area of about 40000 m2, of which over 10000 m2 completely covered and with state-of-the-art manufacturing facilities for sheet metal working and for the realization of industrial carpentry customized products more or less complex.
