Fire Galvanizing

Research has shown that corrosion is the main cause of so much iron decomposition around the world. Among the protection processes already developed, one of the oldest and most successful is zinc-coating by hot immersion, or, as it is more commonly known, Fire Galvanizing.
Fire Galvanizing is a process that consists of cleaning and preparing steel or cast iron and its subsequent immersion in a bath of melted zinc at approximately 450ºC, forming layers of Fe-Zn alloy and an external layer of zinc that will protect and offer metal surfaces greater longevity against corrosion.
