HOT-DIP GALVANIZED STEEL SHEET
Hot-dip galvanized sheet is produced by immersing steel sheets in a molten zinc bath at approximately 500 °C, creating a robust zinc coating on the surface through a continuous galvanizing process. The zinc layer not only provides excellent corrosion protection but also enhances paint adhesion and weldability. As the most widely utilized and cost-effective method, it significantly extends the service life of steel sheets, making it ideal for various applications.
Difference Between Hot-Dip and Electro-galvanized Steel Sheets
The thickness of the zinc coating is crucial for corrosion resistance; a thicker zinc layer provides superior protection. Typically, hot-dip galvanized coatings range from over 30 g/m² to as much as 600 g/m², while electro-galvanized coatings are only 5 to 30 g/m² thick. Consequently, hot-dip galvanized steel sheets offer significantly better corrosion resistance. At Wanzhi Steel, we provide galvanized steel sheets with a maximum zinc layer thickness of 275 g/m² (Z275), ensuring optimal durability and longevity.
Main features of galvanized steel sheets
1.Strong anti-corrosion performance.
2.Good weather resistance.
3.Good welding performance.
4.Beautiful appearance.
5.Strong plasticity.

Product Process
Method of Operation
Hot-dip galvanized steel sheets are processed by immersing them in a molten zinc bath at approximately 500 degrees Celsius. In contrast, electro-galvanized steel sheets undergo treatment at room temperature through electroplating or similar methods, which is why electro-galvanizing is often referred to as the cold galvanizing process.
Surface Smoothness & Adhesion
Electro-galvanized steel sheets typically exhibit a smoother surface compared to hot-dip galvanized sheets. However, their adhesion is not as strong. If you require galvanization on only one side, the electroplating method is suitable. On the other hand, hot-dip galvanizing ensures that both sides of the steel sheet receive a thorough zinc coating for enhanced protection.
