TRANSCRIPT
The plant
The Marcegaglia plant in San Giorgio di Nogaro (Udine) is dedicated to the manufacturing of heavy plates for applications in the building and infrastructure sector, as well as for the carpentry and machinery industry.
The complex spreads over a 105 thousand square metres surface, 33 thousand of which covered, including harbour docks alongside the river Corno.
Manufacturing center has recently seen major upgrades with the starting of a new reheating furnace for normalization treatments.
