What is PrePainted 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.
PrePainted Galvanised Steel Coil is the steel material obtained by surface pretreatment (degreasing and chemical treatment) on the substrate, using roller coating method, coated with one or more layers of liquid coating, and then baked and cooled
Why we galvanize?
Quite simply, galvanizing metal can make it resistant to corrosion.
Without a protective zinc coating, the metal will always be exposed to the elements and will be oxidized and corroded faster. In terms of preventing corrosion, galvanized steel is an economical and effective alternative to austenitic stainless steel, aluminum and other materials
