We may often hear about hot-dip galvanizing of screws, nuts, bolts and other fasteners. Hot-dip galvanizing is a process technology for treating the metal surface layer, mainly to improve the corrosion resistance of metal surfaces. The performance of fasteners is hot-dip galvanized by many manufacturers.
1. Good reliability: The galvanized layer and the steel are metallurgically combined and become a part of the steel surface, so the durability of the coating is more reliable;
2. Comprehensive protection: Every part of the plated parts can be coated with zinc, even in depressions, sharp corners and hidden places can be fully protected;
3. Low processing cost: The cost of hot-dip galvanized antirust is lower than that of other paint coatings;
4. Save time and effort: 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;
5. Durability: In the suburban environment, the standard hot-dip galvanized antirust thickness can be maintained for more than 50 years without having to repair; in urban or offshore areas, the standard hot-dip galvanized antirust layer can be maintained for 20 years without having to be repaired ;
6. The toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.
