Advantages of hot-dip galvanized screws:

1. Low processing cost: the cost of hot-dip galvanizing anti-rust is lower than that of other paint coatings;

2. The toughness of the coating is strong: the galvanized layer constitutes a special metallurgical structure, which can withstand mechanical damage during transportation and use;

3. Durable and durable: In the suburban environment, the standard hot-dip galvanized anti-rust thickness can last for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can last for 20 years without repair ;

4. Good reliability: the galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the durability of the coating is relatively reliable;

5. 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.

6. Comprehensive maintenance: every part of the plated parts can be galvanized, and can be fully maintained even in depressions, sharp corners and hidden places;

In addition, the mechanical performance level of galvanized screws can reach 8.8, while most stainless steel screws can only be -70, such as A2-70, A4-70, which is equivalent to level 7, which is lower than galvanized screws.

Therefore, the use of galvanized screws is wider than that of stainless steel screws, and the amount is more than that of stainless steel screws.

But it needs to be clarified that it is impossible for galvanized screws to completely replace stainless steel screws, and it will always be better than stainless steel screws in terms of corrosion resistance. Therefore, it is necessary to choose the appropriate material according to the occasion.
