ZINC
☆ Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.

HDG
☆ The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
