Common leak points of 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 incoordination and leakage.
2. Leaking issues are quite severe in steel structure color steel roof 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 color steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Multiple factory equipment, high waterproofing requirements.
3. Severe leakage due to elastic deformation of steel structure roofs and vibrations in color steel roofs is more pronounced, especially in southern regions.

Material Selection Principles for Roofing and Eaves Waterproofing in Steel Structure Buildings

The waterproofing layer must match the characteristics of the steel structural roof, requiring materials with strong bonding power to cover seams, high elongation rate, resistance to extreme temperatures, solar radiation, water resistance, air tightness, and good 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, condensation from cold bridges, and multi-curvature structures in traditional roofing systems.
