  • Minimized off-flatness lengths


  • Increased rolling speed
SMSgroup Image


  • Reliable and precise flatness measurement and control


  • Stand-alone measuring system with closed roll surface
  • Flatness control perfectly tailored to the process requirements

Technical advantages

  • Mark-free measurement due to closed roll surface
  • Widest measurement up to 3,000 mm (96 sensors)
  • Max. utilization of flatness actuators
  • Open to any mill configuration (4-hi, 6-hi, 20-hi, etc.)
  • Most stable rolling process, optimized strip flatness
  • Higher rolling speeds allow higher production rates
