Aluminum alloy doors and windows refer to the doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans. They are called aluminum alloy doors and windows for short.  Aluminum alloy doors and windows include doors and windows that are made of aluminum alloy as the base material for the stress bars ( bars that bear and transmit self-weight and load ) and are compounded with wood and plastic, for short, aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows.
 The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials ( aluminum profiles ), the surface treatment and internal processing quality of aluminum materials, and the price of aluminum alloy doors and windows, etc                               The surface of doors and windows should not have obvious scratches, scratches, bruises and other defects.
 2. Coloring surfaces of adjacent members of doors and windows should not have obvious color difference.
 3. There should be no aluminium scrap, burr, oil stain or other stains on the surface of doors and windows, and there should be no overflowing adhesive at the assembly joint.
