  • Disc shears
  • Stretching machine
  • Stretching rollers
  • Multistorey storage loop (accumulator)
• Strip preparation section
  • Strip surface degreasing bath with brushes
  • Strip washing bath
  • Electrolytic pickling bath
    • Designed for increasing the strip surface roughness
  • Strip washing bath
• Strip drying section
  • Electric infrared furnace with ceramic reflectors and tungsten quartz shortwave lamps
    • It has a strip width control system and quickly switches off in case of shutdown
• Precoating section
  • Roller machine for two-side or one-side precoating ( chemical coater)
  • Electric infrared furnace for primer curing
  • Designed for evaporating water vapor and solvent
