High Glossy Roofing Sheet Galvanized Steel Plate 5mm DX51D Z275
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 to provide an effective anti-rust method.
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. These sheets should have a good appearance and should not have defects such as holes, cracks, scum, or white rust.

Immerse the steel in molten zinc liquid to attach a zinc layer. Steps include:
• Pretreatment: Cleaning and degreasing.
• Dip plating: Formation of an alloy layer.
• Cooling: Solidification of the zinc layer.
• Post-treatment: Quality inspection.
Depositing zinc through electrolysis:
• Electrolyte preparation.
• Electroplating: Reduction of zinc ions to metallic zinc.
• Post-treatment: Cleaning and drying for a uniform coating.
