Hot dip galvanizing

This is a process where steel parts are provided a zinc coating for corrosion protection. The zinc coating is relatively thin 70–100 µm, but it is the optimum method for protecting steel against corrosion. Galvanized parts do not require maintenance in a normal environment for about 50 years. This zinc coating also has the ability to “self-heal”, i.e. zinc is able to maintain corrosion protection for up to 5 mm damages and scratches via electrochemical process.
