Roofing color steel sandwich panel is not easy to rust

Color steel sandwich panel is a sandwich panel made of color steel plate and other raw materials. It has good antibacterial and anti-static effects, and is widely used in electronic devices, pharmaceutical industry, aerospace and other fields. Under all normal applications, color steel sandwich panels are not easy to rust, but it is uncertain whether they will rust. If damaged by external force, it is likely to rust.

The color steel sandwich panel on the roof contains iron element. Because of the long-term wind, light sunshine and rain, the surface coating will inevitably be damaged. Once the damage location is touched with acid, alkali and organic solution, it will cause chemical changes and produce compounds, namely rust. When the corrosion is serious, holes will be produced.

In frequent rainy days, the roofing panel will rust after being used for a long time. Once it is rainy, roof corrosion will be damaged by the oxidation and decomposition of natural environment and strong acid and alkali rain. The precipitation will drop down along the bluestone, causing erosion marks. Over time, large-scale erosion will occur to the roofing panel.

In addition, in the construction process of the project, due to the negligence of the staff, the surface coating is damaged, and the purification plate may also be rusted. Therefore, in the construction process, the construction team should pay attention to the project construction to prevent damage to the surface coating.

Apart from the above factors, there are other reasons for corrosion of roofing color steel sandwich panels. If rust is found in application, it shall be properly treated to prevent rust expansion and avoid endangering the service life of roof sandwich panel.
