Since the start of the company in 1971, Impresa Tre Colli S.p.A. has mainly worked on earth excavation and earth moving for the construction of industrial pipelines, in particular oil, gas and water pipelines.

The company’s reputation for reliability and its success acknowledged by the largest Italian clients led Impresa Tre Colli S.p.A. to gradually extend its operations to also include the mechanical assembly of complete oil and gas pipelines as well as the relative compression and pumping installations.
