Common leakage points for steel structure color steel roof and gutters

1. The downspout spans a wide foundation, causing uneven settlement loads and uneven tensile cracks. Under the influence of external temperatures, thermal expansion and contraction, and tensile extensibility, stress imbalances lead to cracking and leakage.
2. Water leakage is quite severe in steel structure color steel roof systems due to installation, construction, roof elastic deformation, and roof vibration. The leakage in steel structure roofs is mainly concentrated in nodes 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. Multiple factory equipment, high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structures and vibrations in 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 select materials with strong bonding power on the cover joints, high elongation rate, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. The steel structure roofing waterproofing system features light weight, excellent waterproof and thermal insulation properties, easy maintenance, and long lifespan. It can completely resolve issues such as leakage and water seepage, condensation on cold bridges, and multi-curvature construction in traditional roofing systems.
