Common leakage points in steel structure color steel roof and gutters

1. Gutter spans with uneven foundation settlement loads can lead to cracking due to temperature fluctuations, thermal expansion and contraction, and the material's tensile and extensile properties, resulting in stress mismatches 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. Leaks in steel structure roofs are primarily concentrated in nodes 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 walls.

Steel structure colored steel sheeting and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Abundant factory equipment, with high waterproofing requirements.
3. Leaking issues are quite severe due to elastic deformation of steel structures on the roof and vibrations of color steel roofs, a phenomenon more pronounced in southern regions.

Principles for Waterproofing Materials Selection for Steel Structure Roofs and Eaves Gutter

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to select materials that have strong adhesion to the roof joints, high elongation, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roofing waterproofing system features light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely solve issues such as leakage and water seepage, condensation on cold bridges, and multi-surface structures in traditional roofing systems.
