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

1. Gutter span over large foundation, uneven settlement load causes cracking; cracks expand due to external temperature influence, thermal expansion and contraction, and poor extensibility, leading to stress imbalance and leakage.
2. Leaking issues are quite severe in steel structure color steel roof systems due to installation, construction, roof elastic deformation, and vibrations. Leaks in steel structure roofs are primarily concentrated at joints such as the vertical and horizontal joints of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and parapet seams.

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

Principles for Waterproofing Materials Selection for Steel Structural Roofs and Gutters

The waterproofing layer must match the variation characteristics of the steel structure roof. It is essential to choose materials with strong adhesion to the cover joints, high elongation rate, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. Our steel structure roof waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long lifespan. It can effectively address issues such as leakage, condensation due to cold bridges, and multi-curvature construction in traditional roofing systems.
