Why steel grating must be galvanized

Why steel grating must be galvanized

The steel grating is actually the service platform grating whose surface layer is solved by hot-dip galvanizing. Why should the surface of the service platform grating be hot-dip galvanized? The original hot-dip galvanizing is equivalent to adding the steel grating. The longevity allows it to be used for decades. Since the surface of non-hot-dip galvanized steel grating is very easy to rust. Rust will reduce its application cycle time. Therefore, hot-dip galvanizing the surface of the service platform grating not only improves the beauty, but also increases its service life. Say it kills two birds with one stone.


 The appearance of the product after hot-dip galvanizing is not only beautiful but also exquisite. The difference between hot-dip galvanized steel grating and non-hot-dip galvanized steel grating depends on its metal surface treatment. There are two types of hot-dip galvanizing: hot-dip galvanizing and cold spraying.


The galvanized service platform grating can prevent air oxidation and increase its service life. The hot-dip galvanized service platform grating plate has strong anti-corrosion work ability in the middle of PH6-PH12. Its service life is very closely related to environmental factors. In a dry natural environment, its service life can reach 70-80 years, industrial production was generally 20-30 years.


The application age of cold spray zinc is relatively short, and the rust condition has just begun to be highlighted in two or three years. Without hot-dip galvanizing, not only the appearance is not smooth and unsightly, but also centralized methods such as painting and surface coating can be carried out. The hot-dip galvanized steel grating has a long service life, reaching 40-70 years.


The surface of non-hot-dip galvanized products is very easy to blacken and rust, while the surface of hot-dip galvanized is very shiny, has a longer service life, and has a beautiful and generous appearance design that is durable.
