According to the color-coated corrugated roofing sheet manufacturer, color steel plates are widely used in home-made structural roofs, such as self-sealing bay windows and self-contained houses. In the north of China, the original vertical wall structure of the house with the color steel plate often has the thermal insulation structural layer, and the metal plate and the wall that is erected in the future are mostly butted, and the structural wall surface is not subjected to any groove fixing and the like, and is used in later use. Due to the influence of wind and rain erosion, temperature change and service life, the sealing of the lap joint is not strict and it is easy to cause leakage.
