1. Due to the low material strength and steel properties of plastic steel doors and windows, its wind pressure and water density capacity are much lower than that of aluminum alloy doors. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. Moreover, because the lining steel of plastic steel doors and windows does not connect to a complete framework system in the corner of the inner cavity of its profile, the plastic welding angle of the window frame, fan four corners, and buty -lines is relatively low.
2. Because the frame and fan component of the plastic steel doors and windows are welded, it should be slightly better than the aluminum alloy doors and windows connected by the screw, but the size of the aluminum alloy doors is high, and the frame and fan are more thoughtful.
3. The audio -visual function of the window is that the audio -visual consequences of the glass with an area of about 80%of the window are. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. The sealing level of the gap between the broken bridge aluminum alloy doors and windows is basically the same, and its sound insulation function is basically the same.
4. It is better to have a hard -combustible wooden doors and windows for the hard -working PVC plastic doors and windows, but it is worse than non -incinerated broken bridge aluminum alloy doors and windows. For the prevention function of doors and windows: Steel doors and windows and aluminum doors and windows are absolutely good, and plastic doors and windows are absolutely poor.
5. Broken bridge aluminum alloy is a good conductive body, so it may be used as lightning protection facilities and can avoid static electricity. According to information, the electro -electrostatic fire protection of plastic can be applied in its name, which can be applied to the anti -static oil agent containing the seasonal amine and salt, which can absorb the water in the air and increase the conductivity. However, domestic plastic doors and windows are not treated with anti -static coatings.
6. A single white white of plastic doors and windows is a magnificent disadvantage. It cannot be satisfied with the rich and colorful various types of outer wall decoration. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. Absolutely speaking, the broken bridge aluminum alloy door has various nominal processing techniques such as powder spraying, anode oxidation, electrophoretic coating, wood grain transfer processing. , Granite and other nominal colors.
The above content of the difference between the difference between the aluminum doors and windows of the broken bridge and the plastic steel is introduced here.
