Common leakage points of steel structure color steel roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand and leak due to temperature influence, thermal expansion and contraction, and the incoordination of tensile and extensile properties.
2. Structural steel color steel roof leaks are quite severe due to installation and construction, roof elastic deformation, and roof vibration. Leaks in steel structure roofs are mainly concentrated in nodes such as vertical and horizontal joints of metal color steel roof tiles, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutter trays, and joints of parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Extensive factory equipment, with high waterproofing requirements.
3. Severe leakage issues caused by elastic deformation of steel structure roofs and vibrations in color steel roofs are more pronounced, especially 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 strength to the cover joints, high elongation rate, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roofing waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long service life. It can completely resolve issues such as leakage, condensation on cold bridges, and complex multi-surface structures in traditional roofing systems.
