Common leakage areas for steel structure colored steel tile roofs and gutters

1. Gutter span and uneven foundation settlement loads cause cracking; cracks expand and leak due to external temperature influences, thermal expansion and contraction, and the lack of coordination in 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 at joints such as vertical and horizontal lapping of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutters, and junctions of parapet walls.

Structural steel color steel sheeting and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Abundant factory equipment; high waterproofing requirements.
3. Severe leakage issues caused by elastic deformation of steel structure roofs and vibrations of color steel roofs are more pronounced, especially in southern regions.

Principles for selecting waterproofing materials for steel structure roofs and gutters

1. The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials with strong bonding power for the cover joints, high elongation rate, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roof waterproofing system features light self-weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long service life. It can completely resolve issues such as leakage and water seepage, condensation on cold bridges, and multi-surface construction in traditional roofing systems.
