The galvanization of crash barrier highlights coating the metal barrier by submerging it into a bath of molten zinc. The bath of molten zinc showcases temperatures around 840°F (449°C). Once removed from the bath, the zinc coating on the metal’s exterior reacts with oxygen in the atmosphere to form (Zno) Zinc oxide. This Zinc oxide further reacts with carbon dioxide in the atmosphere to form a more compact protective layer known as (ZnCO3) Zinc carbonate. This Zinc carbonate reflects a dull grayish film, which is relatively stable and adheres tightly to the surface of the metal. This in turn helps you protect the metal of crash barriers from natural calamities and external elements. Visit: http://www.galvanizers.co.in/blog/why-crash-barrier-needs-galvanizing/
