The core structure of the vertical seam aluminum-magnesium-manganese metal roof system is a special plate-shaped metal plate based on the vertical seam occlusal design. No perforations can be seen on the roof because the support method is hidden under the panel. The connection method of the roof slab is to adopt its unique aluminum alloy fixed support. The vertical seam of the plate and the plate are occluded to form a tight connection, and the connection formed by the occlusal edge and the support can solve the problem caused by thermal expansion and contraction. Plate stress, this advantage is reflected in the ability to make longitudinally ultra-long plates without deformation due to stress. At the same time, the complete accessories supply of this roofing system can meet the requirements of various building forms.

　　1. Large-span roof system: refers to a system that is used for roof purlins with a relatively large spacing and can guarantee various roof design parameters. Such as large stadiums, railway station stands, etc.

　　2. Decorative roofing system: refers to the system used to add some special materials to the roof for aesthetics or to meet the requirements of surrounding buildings. Such as the installation of aluminum veneers, solar panels, etc.

　　3. Special-shaped roof system: refers to a system that makes spherical, S-shaped, ring-shaped and other special shapes according to the shape of the roof.

　　4. Comprehensive roofing system: refers to a component of a roofing system that combines large span, decoration, and shape is made of 65MM rib height aluminum-magnesium-manganese alloy plate (panel) + insulation layer + sound absorption layer + T-shaped support + moisture barrier + support support strip + bottom plate

　　Note: For decorative roofs, there are also special fixtures + aluminum veneers, snow slides, safety bolts, solar panels, etc.

　　The roof made of metal plates in this roofing system has been fully proven through its own years of use, and it is an ideal choice for various residential, commercial and public buildings. The priority of all roofs is the function of weatherproofing, and this roof system completely solves this problem without exception. Positive and negative wind pressure values. Refer to the building load value of the building code of our country, consider factors such as building height, body shape, location, and consider the comprehensive wind pressure coefficient and load probability, and refer to the value of the building roof engineering in the building standard; mainly consider the maximum unfavorable load as Negative wind pressure at corners and edges of buildings.

　　The thermal expansion and contraction of metal building materials in the case of large temperature differences is an inevitable objective law. This roof system summarizes years of use experience, and through the sliding T-code support, the thermal expansion and contraction of the aluminum plate are equally distributed and synchronized. , So that the huge temperature stress can be relieved through proper expansion and contraction, without squeezing deformation or cracking of the plate; ensuring that the overall system works safely during the 50-year use process. The length of a single panel of the roof system can reach 120M, and there is no potential leaking lap joint between the panels, which fully guarantees complete waterproofing. The exhaust port, skylight, and pipeline outlet can be directly passed through, and the accessories can use special technology to ensure water tightness. The hidden support of the roof system and the stable supporting plate structure do not need to penetrate the roof surface, and the loads of wind, frost, rain, snow, and negative wind pressure are safely absorbed. The roof system effectively resolves the stress formed by the large temperature difference on the roof, and even the super-long plate has enough space for expansion and contraction without squeezing or stretching the structure.

　　The roof system is closely connected with the overall lightning protection system of the structure to fully eliminate the problems of lightning damage and static electricity accumulation. The metal plates of the roof of this system are all good materials for exterior maintenance systems, and aluminum-magnesium-manganese alloys are all good conductors. A single whole plate not only provides water tightness, but also is a good conductor, even if there are overlapping parts, it still does not affect its lightning protection performance. The actual construction method is: conceal a ground under the roof panel of the metal roof at intervals of 6-10 meters in the longitudinal and transverse directions, install the corner code at the grounding point, fix one end on the purlin, and fix the other end on the T-code support. The grounding fixed on the purlin can be connected to the lightning protection system constructed by other units. The reason why the aluminum roofing material has such excellent durability is that when the aluminum plate is in contact with the atmosphere, a layer of aluminum oxide film is formed on the surface, and this oxide film protects The inner aluminum plate prevents further corrosion. This oxide film has good chemical resistance, so it is suitable for industrial buildings, areas with serious air pollution or ocean climate. Relevant departments have conducted inspections, and the thickness of aluminum plates lost due to corrosion is 0.5 microns each year. In this case, the 0.7mm thick aluminum plate can still be 0.65mm thick after 100 years of atmospheric corrosion. Therefore, it can be considered that aluminum roofing material is one of the most durable roofing metal materials.

　　There are 35 million tons of aluminum used for roofing in the United States each year. In the construction industry, aluminum alloys are mainly used in extruded profiles and rolled plates. Extruded profiles mainly use 6000 series alloys, AA6062, AA6063, etc. are commonly used grades.

　　The aluminum-magnesium-manganese alloy board roof/curtain wall system mainly uses 3000 series of aluminum-manganese (aluminum-manganese) alloys. The elongation, hardness, tensile strength, yield strength and other indicators of the 3000 series of aluminum-manganese alloys are very suitable for roof crimping, Therefore, the processing of rolling equipment is widely used in exterior maintenance projects such as roof/wall systems, and with various painting systems and coating processes, the appearance of the building becomes colorful, and the corrosion resistance of the aluminum alloy itself is increased. . The thickness of the aluminum material used for the roof is at least 0.7mm. When the thickness of the aluminum material is 1mm, its weight is 2.7kg/m2, and when the thickness is 0.7mm, the weight of the aluminum material is 1.89kg/m2. The length of the coil is not limited. Its main characteristics are: density of 2.7, melting point of 658, linear expansion coefficient of 0.0000023 at temperature of 20-100 degrees, breaking load coefficient of 8-12kg/mm2 (varies according to material hardness), elongation of 10-40 %, the thickness is 0.7~1.2mm, when it is aluminum corrugated board, the thickness can be reduced to 0.6mm. In addition to crimping and rivet fixing, welding can also be used.
