The galvanised iron lost its zinc coating even after it doesn’t corrode. Why does this happen?

Lets look from a different angle corrosion is basically oxidation and in oxidation the electrons are lost. Here we have zinc coated on iron being more reactive the zinc will tend to loose the electrons even if the iron is exposed, even then being good conductor the electrons are given to the iron by the
