Steel structure color steel tile roof and gutter common leakage areas

1. Gutter span and uneven foundation settlement loads cause cracking; cracks expand due to external temperature influence, thermal expansion and contraction, and the ductility of the material, leading to stress imbalance 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 primarily concentrated in joints such as vertical and horizontal joints of metal color steel roof tiles, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutter troughs, and junctions of parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features

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

Material Selection Principles for Waterproofing of Steel Structure Roofs and Gutters

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials that have strong adhesion on the roof seams, high elongation, resistance to high and low temperatures, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. Our steel structure roofing waterproofing system features light self-weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can effectively resolve issues such as leakage, condensation at cold bridges, and multi-surface constructions in traditional roofing systems.
