The properties of the line make it possible to apply a wide range of  preservation coats  (primers to sheets) to meet every customer’s requirements and preferences.

Shotblast enables  scale and corrosion to be removed from a metal surface and preparing the surface for the application of protective preservation primer. Metal priming allows  to protect steel from  corrosion.

  • width: up to 4,600 mm
  • length: up to 18,300 mm

The preservation line consists of the following:

  • charging roller table
  • preheating chamber (designed for metal preheating and scale crust loosening to improve the removal of moisture remains and oil stains from the metal surface)
  • shotblasting chamber (designed for metal surface cleaning up to a purity of   Sa 2.5, as required by ISO 8501−1 (ISO 12944−4). Sheets are shotblasted on both sides simultaneously)
