After the construction of Hefei Xinqiao Airport lasted for several years, it was finally put into use. The atmosphere of Xinqiao Airport was magnificent and the modernist atmosphere was revealed everywhere. The roof of the terminal building is made of alloy aluminum plate, which is a kind of aluminum-magnesium-manganese alloy aluminum plate with higher hardness and better corrosion resistance. The golden yellow upright seaming style is very beautiful.
At this new airport, the first attraction is its terminal. The appearance of the terminal building is streamlined and curved. The entire terminal building is divided into two floors, one underground and one sub-layer. The upper and lower parts of the terminal building are respectively made of steel structure and reinforced concrete frame, and nearly 10,000 tons of metal are used to manufacture the steel frame. The outer protective structure is mainly composed of glass, alloy aluminum plate and stone. The organic combination of steel and glass makes the terminal solid, simple and feminine.
There are many series of current alloy aluminum plates:
3××× series alloy aluminum plate can prevent rust in a relatively humid environment;
The 5××× series alloy aluminum plate has excellent interface, corrosion resistance and high hardness, which makes large-scale industries such as airplanes, ships and automobiles adopt this series of alloy aluminum plates.
The good wear resistance of the 7××× series alloy aluminum plate and the excellent characteristics that will not be deformed after processing are also applied in aerospace manufacturing.
