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

1. Gutter span and uneven foundation settlement loads lead to tensile cracks. These cracks, influenced by external temperatures, cause stress imbalances due to thermal expansion and contraction and extensibility, resulting in cracking and leakage.
2. Leaking issues are relatively severe in steel structure color steel roof systems due to installation, construction, roof elastic deformation, and vibrations. The main points of leakage in steel structure roofs are concentrated at joints such as 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. Severe leakage issues are caused by elastic deformation of steel structures on roofs and vibrations of color steel roofs, which are 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 that have strong adhesion to the roof seams, high elongation, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. Our 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 effectively address issues such as leakage, condensation on cold bridges, and complex curved structures in traditional roofing systems.
