Product Description

Galvanized sheet refers to a steel sheet with a layer of zinc on the surface. Galvanizing is a commonly used economic method to prevent the surface of the steel sheet from corrosion and extend its service life. A layer of metal zinc is coated on the surface of the steel sheet. This zinc-coated steel sheet is called a galvanized sheet. It is an effective anti-rust method. About half of the world's zinc production is used in this process.
Galvanized Steel Sheet
Due to different treatment methods in the coating process, the surface state of galvanized sheets is also different, such as ordinary zinc spangles, fine zinc spangles, flat zinc spangles, no zinc spangles, and phosphating surfaces. Galvanized sheets should have a good appearance and should not have defects that are harmful to the use of the product, such as no plating, holes, cracks, scum, excessive plating thickness, scratches, chromic acid dirt, white rust, etc.

Processing Methods

Hot-dip galvanizing process
Immerse the steel material in molten zinc liquid. Includes Pretreatment, Dip plating, Cooling, and Post-treatment.
Electrogalvanizing (Cold galvanizing)
Depositing zinc through electrolysis. Includes Electrolyte preparation, Electroplating, and Post-treatment for uniform coating.

Advantages

  • Strong anti-corrosion layer extending service life.
  • High cost-effectiveness for rust prevention.
  • Widely used in construction, appliances, and autos.

Disadvantages

  • Environmental concerns (pollution) during hot-dip process.
  • Higher cost compared to untreated steel.
