Aluminum alloy windows and doors are characterized by frames primarily constructed from aluminum alloy profiles.

Aluminum alloy doors and windows refer to doors and windows made with aluminum alloy extruded profiles as frames, stiles, and sashes, commonly abbreviated as aluminum doors and windows. Aluminum alloy doors and windows encompass those with aluminum as the base material for load-bearing members (members that bear and transmit their own weight and loads) as well as those combined with wood and plastic, abbreviated as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows.

The quality of aluminum alloy windows and doors can be roughly assessed from aspects such as the selection of raw materials (aluminum profiles), surface treatment of the aluminum material, and the quality of internal processing, as well as the price of aluminum alloy windows and doors.
