Causes of Water Leakage on the Roof of Steel Structure Factory?

2021-06-01

Steel structure workshops sometimes have water leakage. To solve this problem, the cause of the water leakage should be figured out firstly. The following editor will analyze the causes of water leakage on the roof of the steel structure factory from several aspects.

Design reason

  1. The roof drainage system does not have overflow measures in accordance with the specifications. When the intensity of the rainstorm exceeds the discharge capacity of the rainwater system, it will exceed the lap joints, or even overflow the roof, causing water leakage;
  2. There is no additional L-shaped edge fitting on the upper part of the outer wall of the wall, causing water leakage inside the gutter;
  3. The roof slope design is too small, and the roof rainwater cannot be discharged to the gutter in time.

Material reasons

  1. The color plate of the enclosure part is too thin. After a period of use, the outer plate is corroded or deformed under the influence of temperature, and the gap between the plates increases, causing water leakage;
  2. The quality of the galvanized layer of the profiled board substrate is not good, and the coating is too thin, which causes the profiled board to have a short service life and is easy to rust and damage;
  3. Poor quality of self-tapping screw gasket is easy to crack, and glass sealant is easy to age.

In addition to design reasons and material reasons, it may also be due to the lack of necessary inspection and maintenance during normal use, and the failure to find problems in time. Water leakage of steel structure roof is not an isolated phenomenon, and there are many factors that cause water leakage. We must pay more attention to avoid damage to internal structure and materials caused by water leakage of steel structure factory roof.
