What Is Hot-dip Galvanization?

Hot dip galvanizing is the pickling of iron and steel parts, in order to remove the iron oxide on the surface of iron and steel, after pickling through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then it is usually going to be rust removal treatment of steel structure into the zinc liquid at about 500°c so that the zinc layer is attached to the surface of the steel structure.

Advantages of Hot-dip Galvanizing

1. Low treatment cost: the cost of hot dip galvanized rust prevention is lower than that of another paint coating

2. Durability: galvanized layer and steel is a metallurgical combination, that becomes a part of the steel surface, so the durability of the coating is better

3. Comprehensive protection: Every part of the plating can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected

4. Saving time and labor: Saving labor is definitely a unique advantage of this kind of processing product. In simple terms, hot dip galvanizing products are more convenient and faster than other coating methods when they are galvanized. In addition, it can also save the installation and brushing time in the later period.

5. Simple and convenient inspection: The inspection of this kind of product can be said to be very simple. It is generally possible to check whether such products are qualified by visual and surface tests.
