For over a century, zinc has enhanced the longevity and performance of steel. Zinc coatings provide the most effective and economical way of protecting steel against corrosion which, left unchecked, is estimated to cost an industrialized country’s economy at least 4% of GDP each year. Zinc-coated or galvanized steel offers a unique combination of properties unmatched by any other material.
There are other zinc coating methods used to protect steel including zinc-rich paint, electro-statically (plated) applied zinc, and mechanically applied zinc. These methods of applying zinc to steel for corrosion protection are very different from galvanizing, and may be inappropriate for some situations and environmental exposures.
