Hot-dip galvanization is the way of coating steel strip with zinc, which alloys with the surface of the base metal –strip- when immersing the metal in a molten zinc bath at a temperature of around 450 °C. The main characteristics of the material obtained are:
o Physical barrier: The coating has a higher hardness and strength than any other type of coating.
o Electrochemical protection: Over time, a thin layer of zinc oxide is formed which acts as an insulator for galvanizing.
o Self-cured: On surface scrapes, there is a clogging by chemical reaction of the damaged surface.
Hot Dip Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel:
The first reference of Ingeteam goes 30 years ago when we revamped the nowadays ArcelorMittal’s CGL in Etxebarri. We have come a long way since then, with a number of references between revamps and green-fields bigger than 30, covering different continents and customers.
