What causes rust on the surface of polystyrene color steel sandwich panels?

The most feared thing about polystyrene color steel sandwich panels is rust and corrosion. Rust will affect the performance and life of color steel sandwich panels. What factors can cause damage to polystyrene sandwich panels?

1. In order to purify iron elements, the surface coating will inevitably be damaged by long-term wind, sun and rain. Once the damaged area comes into contact with acids, bases and organic solutions, they cause chemical changes and produce compounds called rust. When the erosion is severe, the holes are removed.

2. It often rains, and it will rust when it blows. Once it rains, the rust of the roof will be damaged by the oxidative decomposition of the natural environment and strong acid and alkali rain. Precipitation can drip from cracks and cause erosion marks. Extensive erosion occurs over time.

3. In addition, during the construction of the project, due to the negligence of the staff, the surface coating is damaged, and the polystyrene color steel sandwich panel may also be corroded. Therefore, in the process of project construction, the construction team should pay attention to the project construction, solve it carefully, and prevent damage to the surface coating.

In addition to the above factors, there are other reasons for the rust of eps sandwich panels. If rust is found in the application, it should be handled properly to prevent the rust from expanding, so as not to endanger the service life of the color steel sandwich panel.
