Why do screw fasteners need to be hot-dip galvanized?In fact, hot-dip galvanizing is a process technology for processing the metal surface, mainly to improve the corrosion resistance of the metal surface. Therefore, in order to improve the performance of fasteners, many manufacturers will perform hot-dip galvanizing on them.Let's follow the editor of the craftsman to understand the benefits of hot-dip galvanizing.
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. Protection: Every part of the plated parts can be plated with zinc, even in recesses, sharp corners and hidden places can be protected;
3. Low processing cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
4. 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;
5. 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-corrosion layer can be maintained for 20 years without repairing ;
