Common leakage points in steel structure color steel roof and gutters

1. Gutter span and uneven foundation settlement loads cause cracking; under the influence of external temperatures, thermal expansion and contraction, and tensile extensibility, stress incoordination leads to cracking 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 the 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 wall.

Structural steel colored steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Extensive factory equipment, high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structures on the roof and vibrations of color steel roofs are quite severe, with the phenomenon being 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 rate, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. Our steel structure roof waterproofing system boasts a lightweight design, excellent waterproof and thermal insulation properties, easy maintenance, and a long lifespan. It effectively addresses issues such as leakage, condensation at cold bridges, and complex multi-surface structures in traditional roofing systems.
