Hot dip galvanizing is a kind of surface treatment technology in the production and manufacturing of fasteners. The common types of hot-dip galvanized fasteners include electro galvanizing, powder galvanizing, mechanical galvanizing and hot-dip galvanizing. In daily life, it mainly carries out different hot-dip galvanizing surface treatment for fasteners according to different requirements of customers.
The main features of hot-dip galvanized fasteners are:
1. 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;
2. 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;
3. Low treatment cost: the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings;
4. 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;
5. 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;
6. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.
