The International Zinc Association (IZA) Africa is reinforcing the importance of zinc galvanizing technology in mitigating corrosion, a natural process that compromises the integrity of steel structures and components across South Africa particularly at the coast.
Extractive metallurgy transforms mineral ores into usable pure metals such as iron, zinc, aluminium and tin, but corrosion drives metals back toward their original mineral state when exposed to oxygen and other environments. Galvanizing with zinc provides a proven solution by applying a metallurgically bonded zinc coating to steel surfaces.
“Hot dip galvanized coatings provide both barrier protection and sacrificial cathodic protection,” explains Simon Norton, Director, IZA Africa. “The zinc forms a dense, adherent series of iron-zinc alloys with the steel substrate, ensuring that zinc preferentially corrodes in aggressive environments, thereby extending the service life of the underlying steel.”
