New zinc-nickel corrosion protection for steel products

Here are the advantages of the process in brief:
- Min. 8 μm zinc-nickel, with max. 500 nm thick-film passivation and sealing
- Over 1,200 h resistance to white rust according to the ISO 9227 salt-spray test
- Appealing colour scheme with improved zinc-nickel plating
- Little tendency to contact corrosion with aluminium; greatly retarded contact corrosion with stainless steel
- High abrasion protection
- Great temperature stability
- Good overpainting properties
- Changeover running since 3rd quarter, 2012
