The Danieli Group is one of the leading suppliers of complete plants and equipment
in the metal industry worldwide. Specialized in turnkey projects supply, it also provides single-
unit machines. In the field of seamless tube and welded pipe plants, it is represented by Danieli
Centro Tube and Danieli W+K IndustrieTechnik. They operate in full synergy with the other divisions
of Danieli Team, particularly with Danieli Centro Combustion (Heating systems), Danieli Centro
Maskin (Finishing lines), and Danieli Breda (Upsetting presses). All processes are integrated by
Danieli Automation (Process control systems, Power and Instrumentation).
Danieli Engineering and Danieli Construction International manage lump sum turnkey projects.
The design, engineering and process technology parts are completed by superior quality
manufacturing of the core equipment, which is carried out in Danieli fully-owned production
centers. There, key process equipment is assembled and pre-tested before shipping in order
to optimize on-site activities. All this leads to an overall responsability of the projects with
consequent time schedule respect and costs full control.
Furthermore, Danieli Service assists customers in maintenance programs, timely supply of original
spares as well as classroom and on-site training activities.
