Magnesium manganese standing seam metal roof and wall panels magnesium manganese German origin and foreign Corus Building Systems Limited. The earliest success stories have stadium in Berlin, Germany, its engineering useful life of 50 years. After the widespread introduction of Chinese market, has been building engineers and designers, owners unanimously approved, widely used in the country. With the technological development of the national economy, the construction industry by the original metal roof and wall color steel widely used, due to the color steel plate useful life is relatively short (about 15 years), due to daydream and design designers and owners philosophy, whether there is another kind of new building material (magnesium manganese alloy plate) in longer life some of it! Here only say that human wisdom is infinite, magnesium manganese alloy plate and it has been used extensively to promote it. Magnesium manganese plate containing chemical ingredients are: aluminum, magnesium, manganese, coated with a significant increase in the (PVDF) life (50 years). A color plate 3 times more, and lighter weight magnesium manganese plate, easy to install and efficient a light weight, high strength, corrosion resistance; ... 2 roof can be bent or made into a fan-shaped plate; 3 installation without penetrating roof, infinitely long plate making 4 seepage, leakage;. insulation, sound insulation; 5 polyester paint a life span of 20 years, fluorocarbon life of 50 years, no color, the color range. standing seam aluminum roof type: YX65-430/330, thickness :0.7-1 .2 mm, using high-quality fluorocarbon coating or color. Building Materials Co., Ltd. Guangzhou Zhen Yu standing seam aluminum roof has the following advantages: 1 advanced design, economical, reasonable and meet the functional requirements of thermal insulation, sound insulation and noise reduction; 2 natural circulation ventilation, long life and corrosion resistance. , the season is good, life-long maintenance-free; 3 exposed surface without screws, eliminating pollution and aging issues, building exterior intact; 4 excellent waterproof performance and good air permeability; roofing systems and structural integrity of the mine 5. system of tight junctions, as lightning lightning pole; 6 roof skylights can be set to automatically open fire smoke windows; 7 roof allows extension in temperature, moving, each plate longitudinal length limitation; 8 can withstand larger loads, allowing installation, maintenance personnel walking in the roof, security firm; 9 bendable made inside and outside the arc, each plate in the longitudinal direction of the unlimited, simple structure, lightweight; 10 fire performance has passed the European fire experiments rating to AA; 11 mobile mechanical equipment on-site processing, installation fast, simple
