Technical assistance target consists of sequential and measurable steps, necessary to achieve goals in a scheduled period of time, with the focus on final customer’s satisfaction.
Danieli believes in collaboration as first act to reach the best results. During the past decades Danieli has set up a dedicated structure and professional teams, located worldwide, able to take prompt action, thanks to the support offered by skilled designers and technological departments in Danieli HQ.

Danieli Service team has faced many complicated situations due to the average age of mill (˜40 years) and the non-standard behaviors of mandrels, establishing specific rules and steps to complete the task, and developing ‘Danieli’s manual of intervention’.
This approach is applied to Danieli Plants, as well as to non-Danieli plants.
