Aluminum alloy window is one of the commonly used window materials in home decoration. Since there are many brands and models on the market, how to identify their quality is crucial. Here are some key indicators that can help identify the quality of aluminum Windows.
Wall thickness
Good aluminum alloy window thickness is generally more than 1.2mm, because the greater the thickness, the higher the strength, the longer the service life.
Appearance
High-quality aluminum Windows should have a smooth surface, uniform color, and no impurities or deformation. At the same time, some pearlescent hard paint Windows are easy to flake, so check whether the surface is peeling.
Leakproofness
Aluminum alloy Windows must be made of high quality sealing materials, without gaps, to ensure sound insulation, insect protection and sealing. Otherwise, it will affect the quality of life of the family.
Service life
Hgh-quality aluminum alloy Windows should have a very long service life, usually more than 20 years.
Material quality
This can be distinguished by looking at the surface finish of the window frame. High quality aluminum window frames are flat, shiny and free of oxidation. On the contrary, it reflects the poor quality of aluminum, and the surface will appear uneven, white or scratched. It can also be distinguished by testing the hardness of the profile. The high-hardness aluminum profile is relatively hard and can withstand the impact and extrusion well, and the anti-theft and security performance of the window has been improved. Sharp objects such as keys can be used for scratching tests, and if white marks can be scratched, it indicates that the hardness of the aluminum is insufficient.
Welding process
Excellent welding process can improve the connection strength of aluminum alloy Windows and avoid window deformation or cracking.
Double glazing
Aluminum Windows installed with double glazing can improve the performance of sound insulation and heat preservation.
Rail quality
Excellent guide rails ensure stable and smooth window opening and closing.
