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

1. Gutter spans and uneven foundation settlements lead to uneven load distribution, causing cracks. These cracks, influenced by external temperatures, thermal expansion and contraction, and the ductility of materials, result in stress imbalances and leaks.
2. Leaking issues are quite severe in steel structure color steel roof systems due to installation and construction, roof elastic deformation, and roof vibration. Steel structure roof leaks are primarily concentrated at junctions such as the vertical and horizontal joints of metal color steel roof tiles, ridge caps, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and parapet seams.

Structural steel color steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Multiple 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, with the phenomenon being more pronounced in southern regions.

Material selection principles for waterproofing of 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. The steel structure roof waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely solve issues such as leakage, condensation at cold bridges, and multi-curved construction in traditional roof systems.
