Common leak 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 fluctuations, thermal expansion and contraction, and the material's extensibility.
2. Leaking issues are quite severe in steel structure color steel roof systems due to installation and construction, roof elastic deformation, and roof vibration. Leaks in steel structure roofs are primarily concentrated at junctions such as the vertical and horizontal joints of metal color steel panels, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and parapet joints.

Wide span, prone to cracking and deformation.
2. Abundant factory equipment with high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structure roofs and vibrations in color steel roofs are quite severe, and this phenomenon is more pronounced 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 choose materials with strong adhesion to the roof joints, high elongation, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. Our steel structure roofing waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation properties, ease of maintenance, and long lifespan. It can completely address issues such as leakage, condensation at cold bridges, and multi-surface constructions in traditional roofing systems.
