Product Introduction
The standing seam metal roof system is a high-performance metal roof solution, widely used in large public buildings, airports, stadiums, industrial plants and other projects with high requirements for waterproofing, wind resistance and durability. Its core advantage lies in the high-rib design, which provides stronger structural rigidity and drainage capacity, while using hidden mechanical locking technology to ensure long-term waterproof sealing.

三、standing seam roof system structure
1、Standing seam roof panel: The thickness is usually 0.9mm-1.2 mm.
2、Waterproof and breathable membrane: It is a high-density polyethylene non-woven fabric that blocks the invasion of wind and rain on the building structure. While strengthening the air tightness and water tightness of the building, it can also provide rare breathability, so that the water inside the enclosure structure can be quickly discharged, effectively avoiding the formation of mold and condensation water.
3、Insulation and sound insulation layer: Rock wool is usually used, and its thickness needs to be determined according to calculation. It mainly plays the role of heat preservation and noise reduction, such as the noise after heavy rain and hail hit the surface layer.
4、Vapor barrier: Generally, polyester film or high-density spunbond polyethylene film is used, and glass wool (with moisture-proof veneer) can also be selected. The vapor barrier can limit the water vapor inside the building from entering the roof, thereby minimizing the occurrence of condensation.
5、Sound-absorbing cotton: Glass wool is usually used, and its bulk density and thickness need to be determined according to calculation.
6、Dustproof layer: Generally, non-woven fabric is used, which is mainly used for dust and dust isolation, and is laid on the upper surface of the roof base plate.
7、Structural base plate: generally perforated galvanized or galvanized corrugated steel plate is used, the thickness is designed according to the purlin distance, and the perforation rate is calculated according to the project. It supports sound-absorbing cotton and thermal insulation cotton, and also plays a decorative role.
8、Roof purlin: generally uses lining purlin and steel purlin, which play the role of structural support and slope adjustment
四、Scope of Application
- Large-span buildings: airports, high-speed rail stations, exhibition centers
- Stadiums: open roofs, high drainage performance required
- Industrial plants: projects with high requirements for corrosion resistance and wind resistance
- Photovoltaic integration: 65mm high ribs compatible with photovoltaic fixtures
