Galvanized screws are mainly hot galvanized, like we usually have black zinc plating, blue zinc plated, blue-white zinc plating screws, etc. Next let me talk to you what are the advantages of galvanized screws?
1. Low processing cost: the cost of hot dip galvanized rust imitation is lower than the cost of other paint coatings
2. Durable: in the suburban environment, the standard hot-dip galvanized screw rust thickness can be maintained for more than 50 years without repair, in urban or offshore areas, the surface of the hot-dip galvanized rust layer can be maintained for 20 years without repair
3 grams rely on good: galvanized layer and steel is metallurgical combination, become part of the steel surface, so the durability of the coating is more dependent.
4. The toughness of the coating is strong: the galvanized layer forms a metallurgical structure that can withstand mechanical damage during transportation and use
5. Comprehensive protection: every part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected
6. Save time and effort: the galvanizing process is faster than other coating construction, and can avoid the time required to brush on the site after installation
Of course, galvanized screws can not completely replace stainless steel screws, in corrosion resistance is still not better than stainless steel screws, so we still need to choose suitable materials according to the use of occasions.
