The typical structure of the aluminumhoneycomb panel adopts 0.5-1mm anti-rust aluminum sheet as outer layer, 0.5-1mm anti-rust aluminum sheet as inner layer and aluminum honeycomb core as middle layer. The panel is a kind of sandwich laminate after bonded, which is free from decolourisation after 10 years exposure to the air if its outer sheet is applied with layer of fluorocarbon coating. 　　Aluminum honeycomb panel is the high grade panel at present. It is characterized by light weight and high strength. Its surface flatness is so good that the other kinds of panels can not be compared to. In addition,it can be machined on site with the surface free from color difference,so it is more and more widely adopted in the modern building by the architects.
