Common leakage points for steel structure color steel roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand due to external temperature influence, thermal expansion and contraction, and tensile extensibility, leading to stress imbalance and leakage.
2. Leaking issues are quite severe in steel structure color steel roofing systems due to installation and construction, roof elastic deformation, and roof vibration. The main leaking points in steel structure roofs are concentrated at junctions 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.

Structural steel colored steel roofing and gutter waterproofing features

1. Wide span, prone to cracking and deformation.
2. Abundant factory equipment with high waterproofing requirements.
3. Leaking issues are quite severe due to elastic deformation of steel structures on the roof and vibrations of color steel roofs, a phenomenon that is more pronounced in southern regions.

Principles for selecting waterproofing materials for steel structure roofs and gutters

The waterproofing layer must match the variation characteristics of the steel structure roof. It is essential to select materials with strong bonding to the cover joints, high elongation, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. The steel structure roof waterproofing system features light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely resolve issues such as leakage and water seepage, condensation on cold bridges, and complex multi-surface structures in traditional roofing systems.
