Aluminum alloy doors and windows refer to doors and windows with aluminum alloy extruded profiles as frames, stiles and fans, referred to as aluminum alloy doors and windows for short. Aluminum alloy doors and windows include wood-plastic composite doors and windows with aluminum alloy as the stress bar (the bar bears and transmits self-weight and load), which is called aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short.
The quality of aluminum alloy doors and windows can be judged from the selection of raw materials (aluminum profiles), the quality of aluminum surface treatment and internal processing, and the price of aluminum alloy doors and windows.
Extended data:
Aluminum alloy doors and windows have the following advantages:
1, light weight and high strength. The density is only 1/3 of steel.
2. Good sealing performance. The sealing performance directly affects the use function and energy consumption of doors and windows. Sealing performance includes air tightness, water tightness, heat insulation and sound insulation.
3. Good durability and convenient use and maintenance. Aluminum alloy doors and windows do not rust, do not fade, do not fall off, almost do not need maintenance, spare parts have a long service life.
4, the decorative effect is elegant. There are artificial oxide films on the surface of aluminum alloy doors and windows, which are colored to form composite films. This composite film is not only corrosion-resistant and wear-resistant, but also has certain flame retardancy and high gloss. Aluminum alloy doors and windows are light in weight, precise and accurate in processing and assembly, convenient and flexible in switching and no noise.
