Common leakage points of steel structure color steel tile roofs 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 leakage points on steel structure roofs are found at vertical and horizontal joints of metal color steel tiles, ridge areas, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and joints of parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features
1. Wide span, prone to cracking and deformation.
2. Extensive factory equipment, with high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structures and vibrations in 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
1. The waterproofing layer must match the characteristics of the steel structural roof. It is essential to select materials with strong adhesion to the roof seams, high elongation rate, resistance to extreme temperatures, sun radiation, water resistance, airtightness, and good 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 multi-surface structures in traditional roofing systems.
