What are the advantages of fasteners after hot-dip galvanizing?
In order to improve the use of fasteners, it will be hot-dip galvanizing process. Hot-dip galvanizing is a kind of process technology that deals with the metal surface, mainly to improve the corrosion resistance of the metal surface. What advantages does this have?
1. Good reliability: Metallurgical bonding between the galvanized layer and the steel becomes a part of the steel surface, so the durability of the coating is more reliable;
2. Comprehensive protection: Each part of the plated part can be plated with zinc, which can be fully protected even in the depressions, sharp corners and hidden places;
3. Low processing cost: The cost of hot-dip galvanizing and rust prevention is lower than that of other lacquer coatings;
4, save time and effort: the galvanized process is faster than other coating construction methods, and can avoid the time required to brush on the site after installation;
5. Durable: In the suburban environment, the standard hot-dip galvanized rust-proof thickness can be maintained for more than 50 years without repair; in the urban or offshore areas, the standard hot-dip galvanized rust-proof layer can be maintained for 20 years without repair ;
6, the toughness of the coating: the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use
