Hot-dip galvanizing is mainly a process technology for surface treatment in the production of fastener products. The common types of hot-dip galvanized fasteners are: electro-galvanizing, powder galvanizing, mechanical galvanizing and hot-dip galvanizing. Kind. In daily life, it is mainly to perform different hot-dip galvanizing surface treatments on fasteners according to different requirements of customers.
The main characteristics of hot-dip galvanized fasteners are:
1. Good reliability: The galvanized layer and the steel are metallurgically bonded and become a part of the steel surface, so the durability of the coating is more reliable;
2. Low processing cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
3. Time-saving and labor-saving: the galvanizing process is faster than other coating construction methods, and it can avoid the time required for painting on the construction site after installation;
4. Durable and durable: In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repairing; in urban areas or offshore areas, the standard hot-dip galvanizing anti-rust layer can be maintained for 20 years without repairing ;
5. The coating has strong toughness: the zinc coating forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
