Common leakage points for steel structure color steel roof and gutters

1. Gutter span and uneven foundation settlement loads cause tensile cracking; cracks expand and leak due to external temperature influence, thermal expansion and contraction, and the incoordination of tensile and extensile properties.
2. Leaking issues in steel structure color steel roof are quite severe due to installation, roof elastic deformation, and roof vibration. The main leaking points in steel structure roofs are found at 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 colored steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Extensive factory equipment, high waterproofing requirements.
3. Severe leakage issues caused by elastic deformation of steel structure roofs and vibrations in color steel roofs are more pronounced, especially in southern regions.

Principles for Waterproofing Materials Selection for Steel Structure Roofs and Eaves Channels

The waterproofing layer must match the characteristics of the steel structural roof. It is essential to choose materials with strong adhesion to the roof seams, 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 waterlogging, cold bridge condensation, and multi-surface structures in traditional roofing systems.
