1. the reliability of galvanized steel plate is good, galvanized layer and steel is metallurgical combination, become a part of the surface, so the durability of the coating is more reliable.

2. galvanized steel plate has corrosion resistance. Galvanized steel plate is to prevent corrosion on the surface of the steel plate to extend its service life, coated with a layer of metal zinc on the surface of the steel plate, this zinc coated steel plate is called galvanized steel plate. Galvanizing is an economical and effective rust prevention method that is often used, and about half of the world's zinc production is used in this process. Galvanized steel plate is an important steel anti-corrosion plate, not only because zinc can form a dense protective layer on the surface of the steel, but also because zinc has a cathodic protection effect, when the galvanized layer is damaged, it can still prevent the corrosion of the iron base material through cathodic protection.

3. galvanized steel coating toughness, galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage during transport and use.
