Product advantages:
Special process and characteristic advantages:
1. Galvanized surface , high brightness, strong corrosion resistance.
2. Carburize tempering treatment, high surface hardness.
3. Advanced technology, high locking performance.
Surface treatment:
1. YZINC/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.
