Plant visits: there is nothing better than seeing with own eyes

Following three days of panel discussions and technology presentations at the Fourth Danieli Innovaction Meeting, attendees were invited to tour various plant sites in three countries, where innovative Danieli process technologies and equipment have been installed and now operate successfully.

Nearly half of all the guests traveled from the Group HQ to attend one of the seven locations during two days of scheduled visits. These plants were chosen among hundreds of locations worldwide where Danieli technologies are performing to customer satisfaction.

On October 4-5, almost 300 DIM guests visited:
