Large welded and machined structures for nuclear-related equipment

Large-scale welding, steel fabrication and machining for custom energy and nuclear-related structures and handling equipment.

Problem solved

Supports delivery of heavy custom structures and equipment where large dimensions, high-strength or stainless steel, welded fabrication and subsequent machining must be coordinated by a regional supplier.

Application contexts

  • Nuclear plant auxiliary equipment
  • Metal-cask handling equipment
  • SMR supply-chain fabrication
  • Large energy infrastructure structures

Technical principle

Fabrication combines welding of steel structures with large machine-tool operations, including machining of parts up to the dimensions and weights stated on the company's official site, subject to project-specific review.

Typical use cases

  • Custom metal-cask handling fixtures
  • Large welded frames and supports
  • Machined energy-equipment structures
