CS-B Galvanized Rolled Steel Coil

Galvanized sheet refers to the steel plate coated with a layer of zinc. Galvanizing is an economical and effective antirust method which is often used. About half of the world's zinc production is used in this process.
Galvanized steel sheet is to prevent corrosion on the surface of steel plate and prolong its service life. A layer of metal zinc is coated on the surface of the steel plate, which is called galvanized steel plate.

Galvanized Steel Coils have gone through a chemical process to keep them from corroding.The steel gets coated in layers of zinc because rust won't attack this protective metal.For countless outdoor,marine,or industrial applications,galvanized steel is an essential fabrication component.The principal method of making steel resist corrosion is by alloying it with another metal,zinc.When steel is submerged in melted zinc,the chemical reaction permanently bonds the zinc to the steel through galvanizing.Therefore,the zinc isn't exactly a sealer,like paint,because it doesn't just coat the steel;it actually permanently becomes a part of it.

Hot-dip galvanization is a form of galvanization.It is the process of coating iron and steel with zinc,which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840°F(449°C).When exposed to the atmosphere,the pure zinc(Zn)reacts with oxygen(O2)to form zinc oxide(ZnO),which further reacts with carbon dioxide(CO2)to form zinc carbonate(ZnCO3),a usually dull grey,fairly strong material that protects the steel underneath from further corrosion in many circumstances.Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel,and is considered superior in terms of cost and life-cycle.It can be identified by the crystallization patterning on the surface(often called a"spangle").
