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

1. The trough span's uneven foundation settlement load causes tensile cracking; under the influence of external temperatures, thermal expansion and contraction, as well as the tensile extensibility, stress incoordination leads to cracking and leakage.
2. Leaking issues are quite severe in steel structure colored steel roof systems due to installation, construction, roof elastic deformation, and roof vibration. The leakage in steel structure roofs is mainly concentrated at joints such as vertical and horizontal joints of the colored steel panels, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutters, and parapet joints.

Steel Structure Color Steel Roofing Sheets and Eaves Waterproof Features

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

Material selection principles for waterproofing steel structure roofs and gutters

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to select materials with strong bonding strength to the roof seams, high elongation rate, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and good aging and weather resistance.
2. Our steel structure roofing waterproofing system boasts low self-weight, excellent waterproof and thermal insulation properties, easy maintenance, and a long service life. It can completely resolve issues such as leakage, condensation on cold bridges, and complex multi-surface structures in traditional roofing systems.
