[0002] The aluminum alloy window is a window made of aluminum alloy material and glass. When making, first, the aluminum alloy material is used to enclose a "U" shaped frame for installing the window. Then, the glass of appropriate size is cut and installed in the frame. Finally, the entire aluminum alloy window is installed on the wall. The aluminum alloy window has the advantages of light weight, firmness, corrosion resistance, heat insulation, and heat preservation.
