Common leakage areas for steel structure color steel roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand due to external temperature changes, thermal expansion and contraction, and the material's extensibility, leading to stress mismatches and leakage.
2. Water leakage is quite severe in steel structure color steel roof systems due to installation and construction, roof elastic deformation, and roof vibration. The leakage in steel structure roofs is mainly concentrated in joints such as the vertical and horizontal joints of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutter trays, and joints of the parapet walls.

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

Principles for selecting waterproofing materials for steel structure roofs and gutters

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials with strong adhesion to the roof joints, high elongation, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roofing waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long service life. It can completely resolve issues such as leakage, condensation on cold bridges, and multi-curvature construction in traditional roofing systems.
