With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.
