Detailed Informations about Galvanized Steel Coil

Hot-dip galvanized coils are produced by passing cold-rolled coils through a zinc bath at a temperature of approximately 460 degrees Celsius. The zinc coating on the steel coil substrate acts as a barrier between the atmosphere and the metal surface. In addition, due to its lower chemical potential compared to iron (Fe), it is attacked and dissolved first, providing excellent corrosion resistance (cathodic protection).
Galvanized steel is defined as carbon steel sheet coated with zinc on both sides. There are two main processes for producing galvanized steel: continuous hot dipping and electrogalvanizing.
The hot dip process involves passing the steel through a bath of molten zinc, while the electrogalvanizing process involves applying zinc by electrolytic treatment. The result is a layer of zinc that adheres tightly to the base metal through an iron-zinc bond coat.
Zinc coating is one of the most effective and economical ways to protect bare steel from corrosive environments. Not only does zinc act as a barrier between the steel and the environment, but it also sacrifices itself to protect the steel underneath. Sacrificial or galvanic protection occurs when two dissimilar metals come into contact and combine with water and oxygen. Zinc preferentially corrodes iron in steel. This protection prevents corrosion of the steel in areas not covered with zinc. Thus, corrosion diffusion from cutting edges, drilling, etc. is minimized.

The applications of Galvanised Steel Coils are numerous, especially in fabrication and manufacturing environments. Construction workers mostly use Galvanised Coils for Roofing applications.
