25 upright double seam: The main advantage of the model YX25-330, YX25-430, YX25-500, advantages YX25-400 standing seam system bite standing seam system is that the whole system with floating structures and concealed installation design. Each roof modulus sink unit are pressing shape, overlap between the various units closely linked to each other, and then the special sewing machine mechanization locking interface. A sheet metal roofing system, the most widely used system. Main features: overall structural waterproofing, drainage features, without chemical caulks, eliminating pollution and the problem of aging, natural circulation ventilation structure, increase building life, easy and specific three-dimensional curved arc shape, the structure is simple, lightweight, safety, construction safety, Fast, accurate and economical. Advantages of magnesium manganese roof (1) the overall structural waterproofing, drainage features strong, do not hit the nail surface, easy to install. (2) corrosion resistance: three times the normal aluminum plates, stainless steel 2 times; (3) to reduce costs, reduce material and prolong life three times. (4) high-strength corrosion resistant aluminum alloy; corrosion resistance in an ordinary environment life of not less than 40 years; (5) light weight; density of aluminum is 2.73g / m3, only 1/3 of the steel. (6) device into the on-site processing, to avoid the long sloping roof single lap produce roof leaks caused by hazards; (7) can be adapted to a variety of all kinds of roof shapes - round, fan-shaped, curved, best meet the designer design concept; (8) can be arbitrarily chosen color. Magnesium manganese applications are widely used in the airport terminal, hangar, railway stations and major transport hubs, convention and exhibition centers, stadiums, exhibition halls, large public * facilities, public service buildings, shopping malls, commercial facilities, residential and other buildings roof and wall systems. Magnesium manganese standing seam system installation is a traditional magnesium manganese plate mounting system, through the use of specialized equipment and occlusal vertical edges, at will along the longitudinal direction of the slats of the vertical edges of two plates bite, which will Roof or wall connection as a whole. System does not require glue, 100% structural waterproofing. This system can save a lot of time to install, especially for large area roof or wall, provides an effective method of reducing costs. In addition, the standing seam system is also very suitable for the climate harsh environment, such as strong winds, rain and a larger place. Standing seam systems standing seam height of 65mm, so that the building showing the appearance of a kind of rhythm and modern.
