Aluminum magnesium manganese metal roofing vertical seaming system

The core structure of the upright seam aluminum-magnesium-manganese alloy metal roofing system is a special plate-shaped metal plate based on the upright seaming design. No perforations are visible on the roof because the way of support is hidden under the panel. The roof panel is connected by its unique aluminum alloy fixing bracket, and the panel and upright seam of the panel are engaged to form a close connection. The connection between the occlusal edge and the support can solve the plate stress caused by thermal expansion and contraction. This advantage is reflected in the ability to make longitudinally oversized panels without deformation due to stress. At the same time, the complete and complete accessories of the roofing system can meet the requirements of various architectural forms.

Main classification of the system：
1. Large-span roofing system: refers to the system used for the large spacing of roofing rafters to ensure the design parameters of various roofing such as: large venues, railway stands, etc.
2. Decorative roof system: refers to the roof for the sake of aesthetics or in order to meet the requirements of the surrounding buildings to install some special materials. Such as the installation of aluminum veneers, solar panels and so on.
3. Shaped roofing system: It refers to a system with special shapes such as spherical surface, S-shaped surface and annular surface according to the shape of the roof.
4. Comprehensive roofing system: refers to the components of the roofing system that combines large spans, decorative and shaped shapes.
Aluminum-magnesium-manganese alloy plate (panel) + insulation layer + sound absorbing layer + T-shaped support + moisture barrier + support support bar + bottom plate.
Note: Decorative roofs also have special fixtures + aluminum veneers, snow slides, safety plugs, solar panels, etc.

System security structure
The roofing system made of sheet metal has been proven by its own many years of use, and is an ideal choice for a variety of residential, commercial and public buildings. All roofs are given priority in weatherproofing, and this roofing system completely solves this problem without exception. The values of positive and negative wind pressure refer to the value of building load in China’s building code. Consider the height, shape and location of the building, and consider the comprehensive wind pressure coefficient and load probability, and refer to the value of the building roofing project in the building standard. The main consideration is that the maximum unfavorable load is the negative wind pressure at the corner and edge of the building.

System roof deformation
The thermal expansion and contraction of metal building materials under the condition of large temperature difference is an inevitable objective law. This roofing system summarizes the experience of many years. Through the sliding T-code support, the thermal expansion and contraction of the aluminum plate is evenly distributed and synchronized, so that the huge temperature stress can be relieved by proper expansion and contraction without the plate. Squeeze deformation or cracking ensures that the overall system works safely for up to 50 years of use. The length of the single block of the roofing system can reach 120M, and there is no potential leaking lap joint between the block and the plate, which fully guarantees complete waterproofing. The outlets of the exhaust vents, skylights and pipelines can be directly worn out, and the accessories can be sealed to ensure watertightness. The hidden roof system support, stable support plate structure, does not need to wear the roof surface. Wind, frost, rain, snow, negative wind pressure loads are safely absorbed. The roofing system effectively decomposes the stress formed by the large temperature difference on the roof, even if the super-long plate has sufficient expansion and contraction space, and does not squash or stretch the structure.

System lightning protection
The roofing system is closely connected with the overall lightning protection system of the structure, which fully solves the problem of lightning damage and static electricity accumulation. The metal plates of the roof of the system are all good external maintenance system materials, and the aluminum-magnesium-manganese alloys are good conductors. A single monolithic plate not only provides water tightness, but is also a good conductor to the extent that, even in the overlapped parts, it does not affect its lightning protection performance. The actual construction method is: a grounding is hidden under the roof panel of the metal roof in the longitudinal direction and the horizontal direction every 6-10 meters, and the corner code is installed at the grounding point, while one end is fixed on the stringer and the other head is fixed on the T-shaped code holder. The grounding fixed to the purlins can be connected to the lightning protection system of other units.
