Aluminum alloy doors are made from surface-treated aluminum alloy profiles, which are processed through cutting, drilling, milling, tapping, and other manufacturing processes to create the door frame components. These components are then assembled together with connectors, sealing materials, and opening and closing hardware to form a complete door.
The profiles and glass styles of aluminum doors differ between northern and southern China. Northern styles are characterized by thicker aluminum profiles and a more robust design, with the most representative style being the grid pattern, and among these, the Tang-style grid is particularly distinctive. Southern styles are characterized by a wider variety of aluminum profiles and more lively designs, with the most representative style being the decorative glass pattern. Other distinctive styles include lattice patterns, ice carving, shallow carving, and crystal shell designs.
