Advantages of fasteners after hot-dip galvanizing

We may often hear that hot-dip galvanizing is performed on fasteners such as screws, nuts, bolts, etc. Hot-dip galvanizing is a process technology that treats the surface of the metal, mainly to improve the corrosion resistance of the metal surface, so in order to improve The use of fasteners, many manufacturers will be hot-dip galvanizing process.

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.
