Title Color steel roof leakage cause
Description The water leakage caused by the material characteristics of the hot sale color-coated corrugated roofing sheet roof leakage. 1. Construction factors a. During the construction process, the corrugated roofing sheet is not protected, and the roof is arbitrarily stepped on, which destroys the flatness of the roof and even the potholes. b. Because the span of the steel structure factory is too large, in many cases, there is a lap joint process in the roof panel. Although the sealant and the rivet are used in the lap joint, the installation is often difficult to reach the design theory standard, resulting in leakage. rain. c. Some color steel gutters are not preserved. Some construction units' gutter anti-corrosion is only brushing anti-rust paint or asphalt paint. After using for a period of time, the gutter is seriously corroded and even rotted and deformed. 2. Use factors a. The house increases the load at will during use, causing the color steel plate to deform. In particular, the load is arbitrarily increased on the roof rafter, and the rafter is deformed, resulting in water in the house area. b. Waterproof glue and sealant are aging, and the necessary maintenance is lack of use.
