2. The sound insulation of plastic steel doors and windows is good: the structure is carefully designed and the joints are tight. The test results show that the sound insulation capacity is 30db, which meets the relevant standards.
3. Impact resistance of plastic-steel doors and windows: Because the outer surface of aluminum-plastic composite profile is aluminum alloy, it has much stronger impact resistance than plastic-steel window profile.
4. Plastic-steel doors and windows have good air tightness: multiple sealing tops or rubber strip are installed at each gap of aluminum-plastic composite windows, and the air tightness is Grade I, which can give full play to the air conditioning effect and save energy by 50%.
5. Good watertightness: The doors and windows are designed with rain-proof structures to completely isolate rainwater from the outdoor, and the watertightness meets relevant standards.
6. The fire resistance of plastic-steel doors and windows is good: the plastic-steel doors and windows are made of UPVC material, which does not spontaneously ignite or support combustion.
7. Plastic steel doors and windows have good anti-theft: aluminum-plastic composite windows are equipped with sophisticated hardware fittings and advanced decorative locks, which makes thieves helpless.
8. Maintenance-free: Aluminum-plastic composite profiles are not easy to be corroded by acid and alkali, will not turn yellow and fade, and hardly need maintenance. When it is dirty, you can scrub it with water and cleaning agent, and it will be as clean as ever after cleaning.
9. Best design: The aluminum-plastic composite window is scientifically designed and adopts reasonable energy-saving profiles, so it is recognized and praised by authoritative departments and can add luster to the building.
