, for example, benefit from lower maintenance and repair costs because of its special properties
Answer:
Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent premature rust and corrosion. ... The corrosion of zinc is very slow, which gives it an extended life while it protects the base metal. Due to the alloying of the Zinc to the iron, cathodic protection occurs.

Galvanisation is the process of zinc-plating other metals to protect them from corrosion. Metal sculptures are shown being cleaned in an acid bath then dipped in a bath of molten zinc. This forms a zinc coating which will protect the metal inside for hundreds of years.
