Common leak points of steel structure color steel tile roof and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks expand due to external temperature changes, thermal expansion and contraction, and tensile elongation, leading to stress mismatches and leakage.
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 points in steel structure roofs are concentrated at junctions such as the vertical and horizontal joints of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all screws on the roof, gutter trays, and joints of the parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features

1. Wide span, prone to cracking and deformation.
2. Multiple factory equipment, 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 phenomenon is more pronounced in southern regions.

Principles for selecting waterproofing materials for steel structural roofs and gutters

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