Common leakage points of steel structure color steel tile roof and gutter

1. Gutter spans with uneven foundation settlement loads can cause cracks. These cracks, influenced by external temperatures, lead to stress mismatches due to thermal expansion and contraction, as well as extensibility, resulting in 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 steel roof structures are mainly concentrated in areas like vertical and horizontal joints of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutter trays, and parapet joints.

Structural steel color steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Many factory equipment, with 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 variation characteristics of the steel structure roof. It is essential to select materials with strong adhesion to the cover joints, high elongation rate, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good 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 in traditional roof systems, condensation on cold bridges, and multi-surface constructions in steel structure roofs.
