The ECOILS coating line was developed in accordance with the highest standards to ensure maximum product quality and environmental protection.
It is equipped with an alkaline degreasing system for coils in aluminium or steel:
- An initial tunnel with high-pressure spraying ramps and mechanical brushes removes oil, grease and any oxides on the strip, ensuring a clean and reactive surface for the next phase.
- A secondary spraying tunnel then rinses with water, followed by a second rinse with demineralised water. The process is concluded in a third tunnel where passivation occurs with the application of a zinc fluorine (zinconium-based) treatment.
