Advantages of hot-dip galvanized flange

So firstly we need to know what is hot galvanizing?Hot-dip galvanizing is an effective way of metal corrosion protection,which is mainly used in metal structures and facilities of various industries.It is to immerse the steel parts after rust removal into the molten zinc solution melting at about 500 C,so that the surface of the steel components is adhered to zinc layer,so as to achieve the purpose of anti-corrosion.After understanding of hot galvanizing,the advantages of hot galvanizing flange are obvious:

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

2.Durable: in the suburb environment, the standard hot-dip galvanized antirust thickness can be maintained for more than 50 years without repair; in the urban area or offshore area, the standard hot-dip galvanized antirust layer can be maintained for 20 years without repair;

3.The reliability of hot-dip galvanized flange is good: the galvanized layer and steel are metallurgical combination, becoming a part of the steel surface, so the durability of the coating is more reliable;

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

5.Comprehensive protection: every part of the plated part can be coated with zinc,even in the depressions, sharp corners and hidden places can be fully protected;

6.The hot-dip galvanized flange saves time and labor: the galvanizing process is faster than other coating construction methods, and can avoid the time required for painting on the site after installation.
