Alessandrin & C. s.r.l. is the result of the merger by incorporation of the company Alessandrin-Prato & C. s.r.l. into the company Korrodex s.r.l., both from the outset (1970-1983) falling under the same ownership and active in industrial and naval plant engineering.
The merger was promoted to optimise the synergies available in the two companies to operate on the market on the basis of past and present experiences.
Alessandrin & C s.r.l. believes that today it is able to satisfy any need in the implementation of mechanical works in the following sectors for the works carried out so far due to the technical and organisational experience acquired and to the high degree of specialisation achieved by its workers:

Chemical, petroleum, petrochemical, ecological, steel and food industrial systems
Oil pipelines, gas pipelines and related compression stations
Buildings and structures in metallic carpentry
Off-shore thermal power stations
Plant engineering and naval carpentry
