The advantages of ordinary aluminum alloy windows are good weather resistance and aging resistance. (Disadvantage) The thermal insulation is not as good as other materials, and the colors are only white and tea. The advantages of plastic steel windows are good sound insulation, thermal insulation, fire resistance, air tightness, water tightness, corrosion resistance, thermal insulation, etc. (Disadvantage) After all, it is a PVC plastic profile. After a long time, the surface will turn yellow and the window will deform, so the service life is 20-30 years.

The decorative surface of doors and windows should not have obvious damage, which means that the protective film on the surface of doors and windows should not have any scratches or scratches. There should be no obvious color difference on the coloring surface of adjacent components on doors and windows. There should be no aluminum shavings, burrs, oil stains or other stains on the surface of doors and windows, and there should be no overflowing adhesive at the assembly joints.

Aluminum alloy windows are equipped with high-quality insulation materials, effectively blocking outdoor heat conduction, reducing energy consumption, and keeping indoor temperatures warm or cool. Aluminum alloy windows have a simple and elegant appearance design, and after surface treatment, they can present various different colors, which can coordinate well with the appearance of the building and improve the overall aesthetics.

Aluminum alloy windows have excellent strength and durability, and are not easily deformed or damaged. They can withstand the pressure and impact of daily use, and maintain their original appearance and structural stability for a long time.
