The reason why the color steel plate is recognized and popularized by a large area is that the key factor is the good waterproof performance of the color steel plate. In some areas of our country, especially in the northwestern regions such as Xinjiang, these places have hot and rainy summers, strong ultraviolet rays, and sun light time. Long, high surface temperature, ordinary asphalt waterproof membrane is not suitable for these places. At the same latitude, the same asphalt waterproof membrane can be used for three years and five years in eastern China, and has a long service life, but in northwestern regions such as Xinjiang, Due to the influence of natural conditions, the service life of most of them has reached the aging state in less than three years. Therefore, solving the roof waterproof problem in these areas has become the key to roof construction. Since the application of color steel sandwich panels on a large area, the roofing panels have penetrated Leakage is no longer a concern for people. In addition, in the construction of concrete, all materials are transported to the site and must be mixed on site, which requires a lot of labor and mechanical shifts, and the construction process is complicated and lasts for a long time; and the color steel sandwich panel is produced by the manufacturer All kinds of color steel equipment are used for processing and production in the industrial plant. The galvanized anticorrosion and polychrome colored paint required are also processed before leaving the factory, and only need to be transported to the construction site for installation, which is greatly reduced On-site operation cycle and operation intensity have reduced the demand for on-site operation labor and mechanical shifts. At the same time, it has also reduced on-site noise and dust pollution.
