Magnesium manganese metal roofing 
 Used in recent years, China's sports venues such as the gradual use of magnesium manganese aluminum roofing sheet metal and other surfaces, as a load-bearing structure, light, good toughness, high strength. According to building shape and function of the use of space below the roof, the roof can be designed in various shapes to decorate the building. 
 Under the surface material is divided into several categories: 
 1, standing seam metal roof system occlusion 
 2, aluminum metal roofing system board 
 3, composite metal roof system 
 Performance: 
 ● The overall weight of the roof light, can achieve large span of space; 
 ● anti-deformation ability. To temperature change, earthquakes and other causes deformation of the weaker absorption features. 
 ● external effects board material of the roof bright, clean and low maintenance costs. 
 ● through the open window and then set on the roof, natural ventilation can be achieved and the exhaust function. 
 ● speed of construction blocks, enabling to shorten the construction period. 
 ● the main material used can be recycled all the environmental materials.
