Common leak points for steel structure color steel roof and gutters

1. Gutter span over large foundation, uneven settlement load causes cracking. Cracks are affected by external temperatures, leading to stress from thermal expansion and contraction, as well as tensile and extensile properties, resulting in uneven cracking and leakage.
2. Structural steel color steel roof leaks are quite severe due to reasons such as installation, roof elastic deformation, and roof vibration. Leaks in the steel structure roof mainly occur at junctions like the vertical and horizontal joints of the metal color steel tiles, ridge, skylight panels, fan base, chimney pipes, all roof screws, gutter trays, and junctions of the parapet walls.

Structural steel color steel roofing and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Extensive factory equipment, with high waterproofing requirements.
3. Leaking issues are more severe due to elastic deformation of steel structure roofs and vibrations in color steel roofs, which is particularly prominent 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 adhesion to the roof seams, 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 features light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely solve issues such as water leakage, condensation on cold bridges, and multi-curved construction in traditional roofing systems.
