Advantages of hot galvanized flange

Today we will introduce the advantages of hot galvanized flanges.

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:

Low treatment cost: The cost of hot dip galvanizing is lower than that of other paint coatings.

Durable: In suburban environment,the standard thickness of hot-dip galvanizing rust-proof can be maintained for more than 50 years without repair;in urban or offshore areas, the standard thickness of hot-dip galvanizing rust-proof layer can be maintained for 20 years without repair;

Good reliability: The galvanized layer is metallurgical bond with the steel and becomes a part of the steel surface,so the durability of the coating is more reliable.

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

Overall protection: Every part of the plated part can be galvanized, even in the depression, sharp corner and hidden place can be fully protected;

Time-saving and labor-saving: Galvanizing process is quicker than other coating construction methods,and can avoid the time required for painting on the site after installation.
