I want to know what are the steel compositions suitable for hot-dip galvanizing?

Sir:

Many, many types of steels are galvanized. Most economically galvanized steels are rather low in silicon, phosphorus, copper, and aluminum. All of these types of steels are more reactive toward the zinc and usually result in thick gray zinc coatings.

There are additives for the molten zinc that reduce the zinc coating thicknesses on the steel.
