Color coated sheet roof is a new type of panel, which is considered to be the most ideal material for modern buildings, and has a long service life. There are many points for attention when installing color coated sheet roof as bottom plate, which should be installed by professional construction master. Aluminum magnesium manganese roof panel is made of aluminum magnesium manganese plate. Even if it is used for a long time, this type of material will not corrode. Under general conditions, it can be used for 40 years to avoid affecting the future use effect. The specific installation precautions are as follows:Before installation, it is necessary to clean the pollutants on the roof of the color coated plate to avoid the corrosion of the panel. In addition, the flatness of the panel should be paid attention to during the installation, and there should be no bending deformation. The color coated sheet roof overlaps a wave crest with each other, so it has been recognized by many users. The whole system of aluminum magnesium manganese roof panel adopts the mechanized locking mode, which can avoid the occurrence of water leakage and has a good drainage system. Especially in the heavy rain weather, the water can be discharged in time, which can avoid the huge pressure caused by water extrusion and prevent the deformation of the project. This will be more solid, there will be no leakage. It is better to anchor reliably, keep the installation flat, and there should be no gap between the plates.
