Surface treatment is used in the production of steel plate. The galvanized steel plate is dipped into a chromic acid solution to form a thin film on the surface of the zinc layer. Even if the chromate film is slightly broken, the chromate in the vicinity of the break will dissolve in the water and collect at the break and form a new film again. This prevents the production of white rust. Apply oil to the galvanized steel plate to prevent direct contact between air and zinc. Always note that the oil must be wiped off the surface of the steel plate before painting. If the galvanized steel plate is to be used for painting purposes, it can be treated with a *ate skin. The *ate will adhere steadily to the surface of the galvanized steel plate, forming a loose, porous surface that will provide a good foothold for the paint to adhere to.

Galvanized steel plate should be stored in a well-ventilated place after production. Or use dryer or drying oven to prevent condensation in the season of high humidity and big difference between cold and warm. At this time Wan can not be wet by immersion. If it is wet by dew or water, it should be dried, and the package can be unpacked and blown dry by using a fan. Stored in a well-ventilated place, if the temperature difference between cold and warm, easy to occur where the dew should be avoided.

(1) Stainless steel plate to do some surface treatment, such as let its surface to form a thin film, thus, to form a loose porous structure, to smooth the surface of the paint spraying work.

(2)Put the stainless steel plate in a cool and ventilated place, avoid moisture and rain, if necessary, some surface protection measures can be taken.
