Differences between Hot-dip Galvanizing and Cold Galvanizing

1）Corrosion resistance: Hot-dip galvanizing is dozens of times more corrosion-resistant than cold galvanizing.

2）Operating methods: Hot-dip galvanizing involves dipping steel into molten zinc at 450-480 degrees, while cold galvanizing is achieved through electroplating or other methods at room temperature.

3）Thickness of galvanized coating: The galvanized coating of hot-dip galvanizing is much thicker than that of cold galvanizing.

4）Surface smoothness: Cold galvanizing has a smoother appearance compared to hot-dip galvanizing.

5）Price: Hot-dip galvanizing is more expensive than cold galvanizing.

6）Single-side coating: Cold galvanizing can be applied to only one side, while hot-dip galvanizing covers the entire surface.

7）Adhesion: Cold galvanizing has lower adhesion compared to hot-dip galvanizing.

8）Charging standards: Hot-dip galvanizing is charged based on the thickness of the material, while most cold galvanizing is charged per square meter.
