1. Corrosion protection of steel using zinc
Corrosion is the destruction of metals under the effect of an aggressive environment, which in fact corresponds to the spontaneous return of a metal, such as iron, to a natural state of greater physical and chemical stability, i.e., the combined state (oxide, hydroxide, etc.).
Zinc is one of the most widely used metals for protecting steel against corrosion through galvanization, but also through electrogalvanizing, metallization, zinc-rich paints, vapor phase deposition, and sherardizing.
This can be explained by two phenomena:
the characteristics of zinc corrosion products;
the sacrificial protection provided by zinc to ferrous substrates.

Economic data
Annual global zinc production exceeds 10 million metric tons, with approximately 60% of this production used for steel protection.
In Europe, approximately 7 million tons of galvanized steel are used each year in manufactured products, including:
3 Mt for the construction/building sector;
0.9 Mt for street furniture;...
