Common leak points of steel structure color steel tile roofing and gutters

1. Gutter span uneven foundation settlement load causes cracking; cracks, affected by external temperatures, lead to stress mismatches due to thermal expansion and contraction, as well as tensile and extensile properties, resulting in 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. Leaks in steel structure roofs are primarily concentrated in areas such as the vertical and horizontal joints of the metal color steel roof tiles, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and junctions of the parapet walls.

Structural steel colored steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Abundant factory equipment; 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 selecting waterproofing materials 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 that have strong adhesion on the roof joints, high elongation rate, resistance to high and low temperatures, solar 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 service life. It can effectively address issues such as leakage, condensation on cold bridges, and multi-curved construction that are commonly found in traditional roof systems.
