Advantages of hot-dip galvanized manhole cover :
1. Low processing cost: The cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
2. Durable: In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repair; in urban areas or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair. ;
3. 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;
4, the toughness of the coating: the galvanized layer constitutes a special metallurgical structure, which can accept mechanical damage during transportation and use;
5, comprehensive maintenance: every part of the plated parts can be galvanized, even in depressions, sharp corners and hidden places can be fully maintained;
6. Save time and effort: The galvanizing process is faster than other coating construction methods, and it can prevent the time required for painting on the site after installation.
