Factors Affecting the Quality of Color Steel Sandwich Panels

Color steel sandwich panels are mainly used as decorative panels for exterior walls of buildings. We are more concerned about its quality. The quality of sheet metal is closely related to various factors. The first is its production process. The production process determines the quality of the sheet.

Factors affecting the quality of color steel sandwich panels

The quality of color steel sandwich panels is not only closely related to the quality of raw materials, but also closely related to the production technology. On the premise of ensuring the same raw materials, if the sandwich panel is of good quality, it is necessary to ensure that the production process and technology pass. The production process mainly includes degreasing, washing, surface adjustment (optional), drying, chemical conversion membrane treatment, and drying early spraying/dipping process. Except for the third step immersion method, chemicals are applied by spraying method. Post treatment generally contains chromium. After post-treatment, not only the excess residue on the surface of the sandwich panel is removed, but also a layer of chromium containing compound is produced on the surface, which improves the corrosion resistance of the panel. The post-treatment of this process is mostly chromium containing compounds.

The main factors affecting the quality of color steel sandwich panels are poor material quality, change of coating surface tension, improper pretreatment, curing defects, coating defects and scratches.

There are many factors affecting the quality of color steel sandwich panels, which are not only reflected in the production process, but also the selection of raw materials for panels. In order to avoid the impact of subsequent use, when selecting sandwich panel manufacturers, attention should also be paid to selecting regular sandwich panel manufacturers.
