What are the advantages and disadvantages of galvanizing?

Advantages:

Galvanizing can effectively prevent the oxidation corrosion of steel in the atmosphere and improve the service life of steel.

Galvanized coating has good corrosion resistance and wear resistance, which can effectively protect steel from mechanical wear and chemical erosion.

Zinc coating is not easy to be damaged, can resist the erosion of most external environmental factors, so it is widely used in outdoor products and building materials and other fields.

Galvanized coating can enhance the stiffness and strength of steel, improve the mechanical properties and load carrying capacity of steel.

Galvanized coating can achieve different appearance effects through different processes, such as bright surface, semi-bright surface and dumb surface, etc., to meet the needs of different customers.

Cons:

Galvanized coatings can be damaged by mechanical wear, corrosion, or other factors, reducing their anti-corrosion ability.

Galvanized coatings may fail at high temperatures, because zinc has a low melting point, and high temperatures can easily make it melt, volatilize or lose its protection.

The production and treatment of galvanized coating requires a lot of energy and water resources, so it has a certain impact on the environment.

Zinc coating may have an impact on human health, because some harmful gases and wastewater are generated during the production and treatment process.
