Common leakage areas for steel structure color steel roof and gutters

1. Gutter spans over large foundation, uneven settlement loads cause tensile cracks. Outside temperature influences, thermal expansion and contraction, as well as the elongation and extensibility generate stress inconsistencies, leading to cracking 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 joints 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 troughs, and joints of the parapet walls.

Structural steel color steel sheeting and gutter waterproofing features

1. Wide span, prone to cracking and deformation.
2. Abundant factory equipment with high waterproofing requirements.
3. Leaking issues are more severe due to reasons such as elastic deformation of steel structures and vibrations in color steel roofs, with this phenomenon being more 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, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. The steel structure roof waterproofing system features light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely resolve issues such as leakage and water seepage, condensation on cold bridges, and multi-curvature structures in traditional roofing systems.
