Because the thickness of the substrate is very important in terms of affecting the service time of glass magnesium sandwich panel. However, some manufacturers of glass magnesium sandwich panel often do tricks on the substrate and the coating or coating of glass magnesium sandwich panel. They reduce the thickness of the substrate, but increase the thickness of peritoneum to reduce the production cost of glass magnesium sandwich panel, which greatly reduces the service life of color steel plate.
2. Observe the leakage edge of glass magnesium sandwich panel
Get a glass magnesium sandwich board, and first observe whether the exposed plate of glass magnesium sandwich board, such as section, is fine and dense, gray, dark and impurities. If the section is fine crystalline, the quality is superior.
