Common leakage points of steel structure color steel tile roof and gutters

1. Gutter spans with uneven foundation settlement loads can lead to tensile cracks. Under the influence of external temperatures, thermal expansion and contraction, and the extensibility, stress imbalances cause cracking and leakage.
2. Steel structure color steel roof leaks are quite severe due to reasons such as installation and construction, roof elastic deformation, and roof vibration. Leaks in steel structure roofs are mainly concentrated in areas such as the vertical and horizontal joints of the metal color steel roof tiles, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutter troughs, and joints of the parapet walls.

Wide span, prone to cracking and deformation.
2. Many factory equipment, high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structures and vibrations in color steel roofs are more severe, and this phenomenon is more pronounced in southern regions.

Principles for selecting waterproofing materials for steel structural roofs and gutters

1. The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials that have strong adhesion to the cover joints, high elongation, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roof waterproofing system features light self-weight, excellent waterproof and thermal insulation performance, easy maintenance, and a long service life. It can completely resolve issues such as water leakage, condensation on cold bridges, and multi-curved structures in traditional roofing systems.
