Common leakage areas for steel structure colored steel roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; the cracks expand and leak due to temperature fluctuations, thermal expansion and contraction, and the material's tensile elongation.
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 areas of 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 roof screws, gutter troughs, and junctions of parapet walls.

Structural Steel Color Steel Roofing Sheets and Eave Waterproofing Features

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

Material Selection Principles for Steel Structure Roofing and Eaves Waterproofing

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, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. Our steel structure roof waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation properties, easy maintenance, and long lifespan. It can completely resolve issues such as leakage, condensation on cold bridges, and multi-curved structures in traditional roofing systems.
