What is Galvanised Steel Coil?
Galvanizing is an effective method of metal anti-corrosion.Galvanized Steel Coil is a steel coil coated with zinc on both sides. It forms a protective coating that isolates the metal from the surrounding environment. The zinc layer can prevent water, humidity and other elements in the air from corroding the steel.
It has two main processes: continuous hot dipped galvanizing and electrogalvanizing.
Hot dipped galvanizing is to immerse the rust-removed metal in the zinc liquid.The zinc layer is attached to the surface of the base material.
Electrogalvanizing is also called cold galvanizing, which uses the principle of electrolysis to coat a thin layer of zinc on the surface of the base metal.
