Sector specialists

A Track Record Tied to the Wind Industry

Wind energy has historically been the origin and one of the main growth drivers of our group. We have been developing onshore and offshore projects alongside international manufacturers and operators in the sector for more than 20 years. Our capability combines highly demanding welded fabrication, engineering, testing, dimensional control and surface treatments to support the client from manufacturing through to validation and maintenance of the equipment.

Projects at sea

Offshore

Metal components and lifting and transport tools

  • We manufacture secondary steel elements for monopiles, jackets and floating structures, such as boat landings, platforms, J-tubes, bellmouths, brackets, nodes and tower access structures.
  • We have facilities very close to the coast, which makes it easier to ship structures and parts by sea.
  • We manufacture high-capacity lifting tools for lifting the main components, as well as transport cradles and frames, among others.
  • We carry out load tests of up to 400 tonnes, measurement using Laser Tracker, non-destructive testing and special anticorrosion coatings and treatments.

Projects on land

Onshore

Lifting, transport and handling tools for large components

  • We manufacture lifting beams, lifting hooks, tilters and specific tools for blades, hubs, nacelles and tower sections, as well as frames and cradles custom-developed for road transport.
  • We have our own testing and verification facilities, such as load testing, 3D dimensional control and non-destructive testing
  • We offer maintenance, repair and adaptation services for the equipment.
