When steel is immersed in a zinc bath, a layer of iron-zinc alloy is created, characterized by a very strong bond – therefore, when properly applied, zinc does not flake off like paint. The outer layer of the protective coating is composed of almost 100% pure zinc, making it flexible enough to withstand mechanical damage. Galvanizing, under moderate exposure to harmful substances, provides protection for at least 60 years! – the company states on its website.
