Common leakage areas of steel structure color steel roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand due to external temperature influence, thermal expansion and contraction, and tensile extensibility, leading to stress incoordination and leakage.
2. Water leakage is quite severe in steel structure color steel roof systems due to installation and 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 metal color steel tiles, ridge, skylight panels, fan base, chimney pipes, all screws on the roof, gutter water trays, and junctions of the parapet walls.

Structural steel colored steel roof tiles and gutter waterproofing features

1. Wide span, prone to cracking and deformation.
2. Abundant factory equipment with high waterproofing requirements.
3. Leaking issues due to elastic deformation of steel structure roofs and vibrations in color steel roofs are more severe, and this is particularly pronounced in southern regions.

Principles for Waterproofing Materials Selection for 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 roofing waterproofing system features light weight, excellent waterproof and thermal insulation properties, ease of maintenance, and long lifespan. It can completely solve issues such as leakage, condensation from cold bridges, and multi-curvature construction in traditional roofing systems.
