What is the approximate price of plastic steel doors and windows in Guizhou?

There is a door around 200 yuan, and the plastic-steel doors and windows have good thermal insulation: the thermal conductivity of plastic in aluminum-plastic composite profiles is low, and the thermal insulation effect is better than that of aluminum 1250 times. In addition, it also has good air tightness. In cold areas, although the outdoor temperature is tens of degrees below zero, the indoor environment is another world. 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. 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. 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, which has first-class air tightness, can give full play to air conditioning effect and save energy by 50%. Good watertightness: The doors and windows are designed with rain-proof structures to completely isolate rainwater from the outside world, and the watertightness conforms to relevant national standards.
