Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 °C (840 °F).
When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances.
Talk to anyone in the hardware and construction industries, and ask them about what is that one concern that drives them to the wall – (not literally of course!) In all likelihood, the answer will be “the quality, longevity, and performance of the metals in use.
has come a long way since it was first invented 150 years ago. The popularity of the process is because of the many qualities and traits it endows steel with. Above all, hot-dip galvanizing is termed as steel’s “best friend” for it endows it with anti-corrosion properties.
