  • Steel for wind energy

Wind energy

ArcelorMittal’s steels have been successfully used in the manufacture of more than 10,000 onshore and offshore wind turbine towers since 2005.

ArcelorMittal produces an extensive portfolio of steels which are used in the major components of a wind farm: foundations, tower, nacelle, generator, gearbox, yaw, pitch and mooring ropes.

Long Products

ArcelorMittal Europe - Long Products' offer includes:

  • SBQ (Special Bar Quality) steels for foundations and flanges, connectors and mechanical parts 
  • Merchant bars for the secondary steel of the tower
  • Mooring ropes: sheated spiral strand wire, sockets and offshore transportation reels

ArcelorMittal offers a large variety of specific beams suitable for the main frame of tower nacelles and substations.
