The Thickest Metal Sheets

We use high-quality, heavy-duty steel plates in the construction of our machines. Material thickness delivers greater strength, stability and a longer service life, even under demanding production conditions.

  • Superior material quality: premium steel selected for strength and durability.
  • Increased stability: thicker plates improve load-bearing performance.
  • Extended service life: robust structures perform reliably for decades.

Mechanical Processing

The core of heavy machinery lies in a robust main frame and precise body machining. Large-scale equipment lets us control accuracy, stability and delivery from the first cut to the final component.

  • Integrated processing: six CNC floor-standing boring and milling machines protect body accuracy and production schedules.
  • A 24-meter CNC boring and milling machine processes complete large-machine bodies for consistent overall precision.
  • Heat treatment and shot blasting: stress-relief annealing minimizes deformation and welding stress for lasting accuracy.
  • All critical spare parts are produced in-house using 12 CNC machining centers for tight tolerances and dependable delivery.
