Pre-treatment before coating
Before duplex coating, we treat the surface with a special product which is chosen according to the type of surface.
Zinc coating
Hot dip galvanising protects the surface against corrosion in the long term. For that we use alkaline or acidic degreasing detergents and ENVIROX preparations to create a proven conversion layer.
- Alkaline degreasing
- Acid degreasing
- Yellow chromating
- Green chromating
- Systems without rinsing (No Rinse)
