The water leakage caused by the material characteristics of the color steel sheet roof leakage.

  1. The thermal conductivity of the low price color corrugated steel sheet itself is large. When the external temperature changes greatly, the temperature difference varies greatly due to the temperature change, and the color steel plate shrinks and deforms due to the temperature change, resulting in a large displacement at the interface. There is a hidden danger of water leakage.
  2. In the steel structure system, due to the temperature change and the external force such as wind load and snow load, the steel structure is prone to elastic deformation, and displacement occurs at the joint to cause water leakage.
  3. Special parts, due to the use of different materials, such as the connection between the parapet wall and the gutter, the roof lighting belt and other parts, due to the stress changes are not synchronized, easy to cause hidden water leakage.
