Aluminum alloy doors and windows are generally: Broken Bridge aluminum profiles have the function of against wind and sand and wind pressure resistance. Inner frame straight material adopts hollow design, strong wind pressure deformation resistance and good vibration resistance. Generally, this kind of aluminum alloy doors and windows has the advantages of beauty, sound insulation, environmental protection and safety! Doors and windows can generally reach 15 to 20 years. Of course, if the protection is better, it may be longer. Aluminium windows is generally available for 50 years, but wearing parts such as pulleys and sealing strips need to be replaced regularly for 5 to 10 years. According to the test results of weather resistance, thermal insulation and sound insulation of aluminum alloy door and window frame, the aging process of hard PVC is a very slow process, and the service life of aluminum alloy doors and windows can reach about 50 years.
