Plastic-steel windows are a special product. From profile production to window assembly, they are carried out at the factory. As long as the installation is in compliance, it is difficult for consumers to have the tools to check the quality of the windows, but this does not mean that consumers cannot check the plastic-steel windows. It is. When you buy a plastic steel window, you can still distinguish its advantages and disadvantages from the following four points.
1. The surface of the plastic steel window should be smooth and flat, without open welding and breakage. The sealing strip is flat without curling, no grooving, and the strip is odorless.
2. When the plastic steel window is closed, there is no gap between the fan and the frame. The four doors and windows are connected as one body without screw connection. The sliding door and window should be free to slide, the sound is soft, and no dust falls off.
3. There are steel linings in the frame and fan of the plastic steel window. The glass is installed flat and firm and does not directly contact the profile. If it is double-layer glass, there should be no dust and water vapor in the interlayer, and the components of the switch are tight and flexible.
4. Plastic steel windows must be professionally processed in the factory workshop and cannot be produced on site.
