How does the steel grating rust? There are many things that users need to pay attention to, which requires users to pay attention to and maintain in a timely manner to ensure that the platform plate will not collapse, the ceiling plate will not fall and other accidents. Below is a detailed description for you.
In fact, as long as the steel grating is produced and stored well, the white rust of the steel grating can generally be avoided. In the production of steel grating, the surface treatment is selected, and the steel grating is immersed in a chromic acid solution to form a low-activity film on the surface of the zinc layer. Even if the chromic acid film is slightly damaged, the chromate near the crack will dissolve in water, converge to the crack, and form a new film again, which can effectively avoid the outbreak of white rust.
There is oil on the steel grid to avoid direct contact between air and zinc. However, it should be noted that before painting, the oil stains on the surface of the steel grating should be wiped off. If the steel grating is to be painted, a phosphate coating can be used. Phosphate will firmly adhere to the surface of the steel grating, forming a loose and porous shape, which can provide an excellent foothold for the coating and achieve strong adhesion.
The produced steel grating should be stored in a well-ventilated place, or in different seasons with high humidity and different temperatures, use a drilling machine or furnace to avoid condensation. Be careful not to get wet with water. If you get wet with dew, you should deal with boredom. You can also open the package and blow dry with an electric fan. Store in a well-ventilated place. If the temperature difference between cold and warm is large, avoid placing it in a place that is prone to condensation. All in all, as long as we do the above points, we can avoid white rust on the steel grille.
