Common leak points for steel structure color steel tile roofs and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand due to external temperature changes, thermal expansion and contraction, and 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 vertical and horizontal joints of metal color steel panels, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutter trays, and joints of the parapet wall.

Steel structure color steel roofing and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Factory equipment abundant, high waterproofing requirements.
3. Severe leakage due to reasons such as elastic deformation of steel structures and vibration of color steel roofs is more pronounced, particularly in southern regions.

Principles for selecting waterproofing materials for steel structural roofs and gutters

The waterproofing layer must match the characteristics of the steel structural roof and must use materials with strong bonding force on the cover joints, high elongation rate, resistance to high and low temperatures, sun radiation, water resistance, air tightness, and good aging and weather resistance.
2. The steel structure roof waterproofing system features light self-weight, excellent waterproof and thermal insulation properties, easy maintenance, and long lifespan. It can completely solve issues such as leakage, condensation on cold bridges, and multi-surface construction in traditional roofing systems.
