Hot-dip galvanizing is mainly a process technology for surface treatment in the production of fasteners. The most common types of hot-dip galvanized fasteners are: electro-galvanized, powder-galvanized, mechanical galvanized and hot-dip galvanized. Usually, the fasteners are subjected to different hot-dip galvanizing surface treatments according to the different requirements of customers.
The main advantages of hot-dip galvanized fasteners are:
1. Comprehensive maintenance: Every part of the electroplated parts can be galvanized, even in recesses, sharp corners and hidden places can be fully maintained.
2. Good reliability: the galvanized layer is metallurgically combined with the steel to become a part of the surface of the steel, and the durability of the coating is more reliable.
3. The coating has strong resistance: the galvanized layer constitutes a special metallurgical structure, which can withstand mechanical damage during transportation and use.
4. Time-saving and labor-saving: the galvanizing process is more convenient than other coating construction methods, which can avoid the time required for coating on the construction site after installation.
5. Low processing cost: The cost of hot-dip galvanizing and anti-rust is lower than other coatings.
6. Long service life: In suburban environments, the thickness of the standard hot-dip galvanized anti-corrosion layer can be maintained for more than 50 years without repair; in urban areas or offshore areas, the standard hot-dip galvanized anti-corrosion layer can be maintained for more than 20 years without repair.
