Electrogalvanized steel
Standard of reference EN 10152
Coating identification (ZE)
Electro-galvanised steels are electrolytically coated with zinc to obtain a product with the same characteristics of use of cold-rolled steels and at the same time have a greater protection against corrosion.

Zinc magnesium
Corrender is the intuition which extends the life of coated steel!
Specific stress tests have shown that the zinc-magnesium layer protect against water, ammonia, chlorine, weathering and more than the classical zinc coating therefore improving pressing and painting characteristics too!tura.
High corrosion-resistant zinc-magnesium coated steel (Corrender)
Product description:
What is zinc magnesium?
Zn alloy +1,5% Mg + 2% Al (average values)
Protection:
The layer of coating, which has formed, delays the development of corrosion.
This results in a reduction of the thickness of the zinc and better anti-corrosion protection.
Product characteristics:
Better anti-corrosion protection (a formation time of rust greater by 5 times was observed)
Superior scratch resistance (hardness is two times greater)
Workability: excellent adhesion of layer of zinc-magnesium coating (particles do not detach)
Improved adhesion of painting
Welding: there are no notable advantages – the only noteworthy fact is that there is less coating so welding is easier
Applications:
- In humid and/or alcaline environments PH < 14
- Contact with cement
- Systems which house animals
- In chlorine environments
- Coastal areas
- Swimming pools
- In ammonia environments
- In chlorine environments (seaside, swimming pools)
- When anti-corrosion protection is strongly needed
- Instead of galvanized steel with high zinc coating
- Construction industry
- Use as pre-painted
- Industry and automotive industry
- For painted and non painted* applications
