Standing seam system is the introduction of one of the most advanced roof building envelope system. The system has been magnesium manganese alloy roof design mainstream in the United States and Europe, has been widely used in the country, such as: stadiums, convention centers, airports, railway stations and large industrial plants and other large landmark building. Magnesium manganese alloy roof panel system: magnesium manganese standing seam roof panel system board design in particular to strengthen the board reinforcing ribs, in order to increase the structural strength, and the exterior of the building stronger lines texture suitable size inside and outside the arc modeling of architectural design. Aluminum, magnesium, manganese material superiority. The tensile strength of 265MPa is 2.5 times the strength of the aluminum; 2. Corrosion Resistance: is 3 times that of ordinary aluminum is 2 times that of stainless steel; 3. Noise reduction and shock absorption, can withstand greater shock loads; 4. Excellent electromagnetic shielding performance of the human brain does not hurt; 5. Is an ideal environmentally friendly materials, does not release harmful toxins; 6. Lower costs, reduce materials, and extend the service life three times. Magnesium manganese alloy roofing system advantages: 1, the use of high-strength corrosion-resistant aluminum alloy; corrosion resistance in the ordinary life of not less than 40 years; 2, the surface coating increases resistance to acid rain and industrial corrosion, while the UV does not react against microbial aging; 3 standard machine lock side to form a durable, solid connection; 4, the experiment has passed fire safety regulations in the United Kingdom and Germany, the fire rating of AA; 5, has a good anti-heat radiation performance; 6, mature lightning protection system design, roof can be used alone as the air terminal, without having to set up with lightning. Can also avoid RA with or lightning rod with the use of the composition of a secure lightning decency; 7, durable and during normal use without any maintenance costs, high recycling value, cost, suitable for roofing stamped and refurbishment; 8, can be adapted to the roof of a variety of shapes - spherical, fan-shaped, curved, best meet the design concept of the designer; 9, rich colors, and a wide range of selection, you can use aluminum-magnesium-manganese alloy steel, aluminum and The use of the color steel plate, stainless steel plate; 10, light weight; density of aluminum 2.73g/dm3, only 1/3 of the steel. 11, high strength; composition, fabrication and heat treatment method can achieve high strength. 12, surface finish and elegant appearance. Anodizing, electrophoresis, chemical treatment, polishing, paint processing. 13, good plasticity, easy processing; 14, good electrical conductivity. Non-magnetized and low spark sensitivity, can avoid electromagnetic interference and reduce the flammability of special circumstances. 15, easy installation; the aluminum metal riveted, welded, glued, or a variety of ways to connect. 16, environmentally friendly, 100% recyclable recycling. 17 using hidden fixing, the entire roof has no holes, reducing roof leakage risks; 18, the aluminum support and the roof outer panel sliding engagement can be eliminated Roofing damaging stress generated due to the temperature difference; 19, the device can enter the site processing, to avoid single roof slope too long roof panel lap leakage hazard; 20 No connection port, no screw holes, the appearance of the building is complete; 21, bend made of inner arc and outer arc; 22 can be used for a small slope to 1.5 °'s roof; 23, excellent wind pressure performance (with the bottom plate), especially typhoons, storms more areas; 24, can eliminate the pressure generated by heating or cooling; 25, simple, fast machine roll together convenient construction, economic; 26, to facilitate the laying of acoustic insulation layer; 27, without chemical caulking compounds, eliminating the problem of pollution and aging; 28, roof maintenance free; 29 can be produced on site; upright double lock side ---- ------------------------------------------- system upright double seaming surface to support roofing system widely used in large sloping roof and curved roof. The system in Europe and the United States has been very mature, the techniques and materials used in the construction field for over 100 years, become one of the symbols of many European cities. Specialized vertical edges and automatically engaging device, and two along the plate longitudinal direction of the overall upward vertical section, is locked by a double hemming so that the roof is connected as a whole. System advantages of the full realization of three-dimensional curved arc, specificity elegant and beautiful: * unique the upright double locking edge technology to provide reliable dense water resistance, wind resistance, can also be applied in typhoons, rainstorms area * excellent durability, adaptability * Excellent insulation, noise performance * Duozan of metal material selection system upright double lock side surface to support the roofing system widely used in the large sloping roof and curved roof.
