3. Main steps in a galvanizing operation
Regardless of the process
-
Surface preparation
The main purpose is to clean the steel surface of exogenous contaminants (dust, oils, abrasion fines) and endogenous contaminants (oxides).
Depending on the process, it may be supplemented by a fluxing step to improve and regulate steel/zinc reactivity.
These operations contribute to the quality of the interface (regularity, alloy distribution)...

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;...
