Plastic steel doors and windows must be installed in compliance with specifications, and it is difficult for consumers to have tools to check the quality of the windows. Jinan plastic steel profile manufacturers tell you a few tips, which can be selected from the following factors:
1. The surface of the plastic steel window should be smooth and flat, without welding fracture, the sealing strip should be flat without crimping, no grooving, and the rubber strip should be odorless.
2. Plastic steel window frames and fans have steel linings. 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 switch components are tight and flexible.
3. Plastic steel windows must be professionally processed in the factory workshop, not on-site production.
4. When the plastic-steel window is closed, there is no gap between the fan and the frame. The four doors and windows are all connected together without screw connection. The sliding doors and windows should slide freely, the sound is soft, and there is no dust falling off.
