Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
It forms a deposition of zinc which prevents corrosive substances from reaching the underlying steel or iron.
The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
The zinc protects its base metal by corroding before iron.
