1. Low treatment cost: the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings;
2. Durable: in suburban environment, the standard hot-dip galvanized rust proof thickness can be maintained for more than 50 years without repair; In urban or offshore areas, the standard hot-dip galvanized antirust coating can be maintained for 20 years without repair;
3. Good reliability: the zinc coating and steel are metallurgically combined to form a part of the steel surface, so the durability of the coating is more reliable;
4. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;
5. Comprehensive protection: every part of the plated parts can be plated with zinc, and can be fully protected even in the depressions, sharp corners and hidden places;
6. Time saving and labor saving: the galvanizing process is faster than other coating methods, and the time required for painting on the site after installation can be avoided.
7. Low initial cost: generally, the cost of hot-dip galvanizing is lower than that of applying other protective coatings. The reason is very simple. Other protective coatings such as sanding and painting are labor-intensive processes. On the contrary, the process of hot-dip galvanizing is highly mechanized and closely controlled in plant construction.
8. Simple and convenient inspection: the hot-dip galvanized layer can be tested by visual inspection and simple nondestructive coating thickness table
9. Reliability: the specification of hot-dip galvanizing is generally in accordance with BS EN ISO 1461, which limits the minimum thickness of zinc layer, so its rust proof period and performance are reliable and predictable.
