Aluminum alloy doors and windows

　　The al-alloy door and window refers to that windows and doors with the extruded aluminum alloy profiles as frames, stiles and leaves.

　　The al-alloy door and window could be divided into: sliding window, flat-opening, sliding door, telescoping, overhanging and outward tilting, etc.

　　Features of al-alloy door and window

　　1. Light weight and high strength. The cross section of the door and window shall be that consisting of the hollowing and thick wall, which facilitates the application and alleviates the quality. Compared with steel doors and windows, the al-alloy door and window are lighter by 50%. When its specification is large and there is a light quality, it has the higher bending stiffness.

　　2. Excellent closed features. The closed feature is a crucial performance parameters. Compared with the general wood windows and doors, it has the excellent performance in the leak-proofness, tightness and insulation property.

　　3. Small deformation in application. It has the sound bending stiffness and the cold connection is selected in the manufacture process. The screw, anchor bolts and aluminum nails are selected in the middle of transverse and longitudinal members and the installation of the hardware. It is a connecting part of the aluminum angle and other categories, connecting the frame and sector components as a whole.

　　4. The building facade is beautiful and elegant. Firstly, its modeling design is beautiful and elegant and the window and door has a large area, making the actual effect simple and bright; Secondly, its color is also attractive and the materials of the door and window are solved through the air oxidation and coloring. It could present the silver, orange, bronze, copper, yellow, grey black or other grains. Its shape is simple and elegant. The lacquering or surface maintenance are not required.

　　5. Corrosion resistance and convenient application and maintenace. The aluminum alloy doors and windows do not need to be painted, do not fade or fall off. The surface will not be maintained. The al-alloy door and window has the high compression strength and sound stiffness. It is durable and agile to open and close without noise.

　　6. Quicker construction speed. The labor capacity is small for the installation of the al-alloy door and window, and the construction speed is quicker.

　　7. Facilitate the industrial production The large industrial production could be carried out in the plants for the processing of aluminum alloy door and window profiles, manufacture of the parts of supporting facilities and the hydraulic seals, and window and door installation and test, which is conductive to complete the standardized door and window design, commodity generalization and parts integration, as well as the commercialization of the window and door.
