1. The reliability of galvanized steel sheet is good. The zinc coating and steel are metallurgically bonded and become part of the steel surface. Therefore, the coating is more durable and reliable. 2. Galvanized steel sheet is corrosion resistant. Galvanized steel sheet is coated with a layer of metal zinc to prevent the surface of the steel sheet from corrosion and extend its service life. This zinc-coated steel sheet is called galvanized steel sheet. Galvanizing is an economical and effective rust prevention method that is often used. About half of the world's zinc production is used for this process. Galvanized steel sheet is an important steel anti-corrosion sheet, not only because zinc can form a dense protective layer on the surface of steel, but also because zinc has a cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of the iron base material through cathodic protection. 3. The coating of galvanized steel sheet is tough, and the zinc coating forms a special metallurgical structure that can withstand mechanical damage during transportation and use.1. Advantages Galvanized steel sheet has good anti-oxidation ability. The surface of galvanized steel sheet has strong anti-oxidation ability, which can enhance the anti-corrosion penetration ability of parts. Galvanized steel sheet has the advantage of overall protection. Every part of the plated part can be plated with zinc, and even in recessed places, sharp corners and hidden places, it can be fully protected. Galvanized steel sheet is durable. In suburban environment, the standard galvanized anti-rust layer can be maintained for more than 50 years without repair. In urban areas or offshore areas, the standard galvanized anti-rust layer can be maintained for 20 years without repair.
