What is Galvanized Steel?


Galvanized steel is a type of steel that has been coated in a layer of zinc that helps prevent the underlying steel from rusting. This layer is usually quite thin, often measured in thousandths of inches or microns. To create galvanized steel, the zinc layer is typically added well after melting, refining, and shaping the steel plate or sheet. Sometimes it is even done after manufacturing processes have been performed on it such as bending or welding.


How Does Galvanized Steel Resist Corrosion?


Galvanized steel resists corrosion because of the zinc coating covering the carbon steel. The zinc layer serves two purposes:


It prevents oxygen from coming into contact with the steel, therefore reducing the possibility of corrosion.


Even if the zinc coating were to experience minor damage and expose small amounts of iron to the atmosphere, the nearby zinc on the rest of the coating is more reactive than steel. This makes the zinc more likely to attract an oxygen molecule than the iron, which prevents rust from forming on the steel.

Application of Galvanized Steel


Galvanized steel is widely used for galvanized steel coil, galvanized steel scaffolding, galvanized steel planks, and galvanized steel pipe.
