1. משקל קל וחוזק גבוה. סגסוגת אלומיניום materials are mostly hollow-core thin-wall composite sections, which are convenient to use and reduce weight, and the sections have high bending strength, and the doors and windows made are durable and have small deformation.
2. Good sealing performance. Airtight performance is an important performance index of doors and windows. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have better air tightness, water tightness and sound insulation performance. The airtightness of the sliding doors and windows of aluminum alloy doors and windows is slightly worse than that of the casement doors and windows. לכן, nylon tops are added to the structure of the sliding doors and windows to enhance their airtight performance.
3. עמיד בפני קורוזיה, easy to use and maintain. סגסוגת אלומיניום doors and windows do not rust or fade, the surface does not need to be painted, and the maintenance cost is low.
4. High strength, good rigidity, עמיד.
5. High use value. In architectural decoration engineering, for high-rise buildings and high-grade decoration projects, if the decoration effect, air-conditioning operation and long-term maintenance are comprehensively weighed, the use value of aluminum alloy doors and windows is superior to other types of doors and windows.
6. עמיד בפני קורוזיה, easy to use and maintain. Aluminum alloy doors and windows do not need to be painted, do not fade or fall off, and do not require maintenance on the surface. Aluminum alloy doors and windows have high strength, good rigidity, עֲמִידוּת, light and flexible opening and closing, and no noise
