Galvanized steel, especially hot-dipped galvanized steel, is the least expensive of all coated steels with the same coating thickness. The cost of coatings or paints for metallic coated steels, aluminum, chromium, aluminum-magnesium, etc., and non-metallic coated steels, such as PPGI, PPGL, etc., is higher than that of galvanized steel. However, the function and service life […]

Galvanized steel is protected against rust by a surface coating that insulates it from air, water, etc. In normal environments, galvanized steel with a high zinc coating has a lifespan of 20–50 years. However, surface rusting often occurs due to humid storage environments, thin zinc coatings, etc. Effective surface preparation and preventive measures are essential.

PPGI, Pre-Painted Galvanized Iron, and PPGL are color-coated steels made from cold-rolled or galvanized steel substrates coated with organic paints. They are widely used in the construction and manufacturing industries for their aesthetics, rust resistance, and workability. Wanzhi Steel has provided many solutions to appliance manufacturers and roof and wall fabricators in over 100 countries.

Galvanised steel is made up of a steel sheet and a zinc coating. The steel sheet rusts when it comes into contact with air, water, etc., so it is coated with a metallic coating to slow down the rusting process. Therefore, when the outer coating of zinc is damaged, the galvanized steel will also rust.

If you are looking for high-quality galvanized steel, welcome to visit Wanzhi’s factory. In March, we received two batches of galvanized steel customers to visit, and introduced our production lines and laboratories to customers in detail. We have a warehousing center, laboratory, production center, from the completion of production, we will conduct quality testing in
