Zinc is a unique and very useful nonferrous metal. The largest market for metallic zinc is its usage in high performance, corrosion control coating systems. Zinc is resistant to most atmospheric conditions, yet it remains sufficiently reactive to cathodically protect ferrous metals such as iron and steel.
Regardless of how the zinc is applied, whether by zinc spray, sherardizing, zinc plating, hot dip galvanizing, etc., corrosion protection of ferrous surfaces is provided in two different ways: as a continuous, long-lasting corrosion barrier and also as a galvanic protective layer.
Zinc as a substrate provides a smooth, dull gray surface that is very reactive. Over time the zinc layer on buried pipe changes into a dense, firmly adhering, impermeable and uniformly crystalline layer of insoluble compounds consisting of zinc oxides, hydrates and zinc salts of different compositions.
To summarize, in addition to providing cathodic protection, zinc as a substrate increases the life and effectiveness of the coatings applied over it.
