uPVC Profile door and window companies are basically the same in the use of manufacturing equipment, resulting in an obvious tendency for products to be homogenized between companies. In the future, the development of plastic steel profile door and window technology should focus on market differentiation strategies and provide targeted products for different market needs More than 40% of consumers expressed concern about the organic combination of buying doors and windows and home decoration colors. Facing the huge domestic market demand, and trusting the requirements for building energy saving and the improvement of the technology of plastic steel doors and windows, it will promote the development of plastic steel Occupy a more important role in the future door and window market. The outstanding properties of plastic steel profiles are introduced as follows:
1. Thermal insulation and energy saving: uPVC Profile multi-cavity structure, with good thermal insulation performance, low heat transfer coefficient, only 1/357 of steel, 1/1250 of aluminum, its economic and social benefits are huge .
2. Airtightness: all the gaps in the installation of plastic steel doors and windows are equipped with rubber and plastic sealing strips and tops, so the airtightness is much higher than that of aluminum alloy doors and windows. The airtightness of plastic steel casement doors and windows is higher than that of sliding windows. Air tightness. Under normal circumstances, the air tightness of casement windows can reach level five, and the air tightness of sliding windows can reach level two.
3. Water tightness: Because uPVC Profile has a unique multi-cavity structure, it has an independent drainage cavity, no matter it is a frame or a fan, the water can be effectively discharged. The water tightness of plastic steel casement windows is much higher than that of sliding windows. Under normal circumstances, the water tightness of casement windows can reach level five, and sliding windows can reach level three to four.
4. Wind pressure resistance: In the independent plastic cavity, 1.5~3MM thick steel lining can be filled, and plastic steel can be selected according to the local wind pressure value, the height of the building, the size of the opening, and the design of the window. Thickness and profile series to ensure the building's requirements for shaped doors and windows. High-rise buildings can choose large-section sliding windows or internal casement windows, and the wind pressure resistance can reach six levels or more. Low-rise buildings can choose external casement windows or small cross-section sliding windows. The wind pressure resistance of windows is generally at level 3.
5. Corrosion resistance: uPVC Profile has a unique formula and good corrosion resistance. If anti-corrosion hardware and stainless steel profiles are selected, its service life is about 10 times that of steel windows.
6. Weather resistance: uPVC Profile adopts a unique formula to improve its cold resistance. Plastic steel doors and windows can be used in environments with large temperature differences (-50℃~70℃) for a long time, and will not be deteriorated by sun exposure and humidity. , Aging, embrittlement and other phenomena, the earliest plastic-steel doors and windows have been used for 30 years, and their materials are as good as before. According to this calculation, the service life of plastic-steel doors and windows under normal conditions can reach more than 50 years.
7. Rich colors: The application of colored uPVC Profile adds a lot of beauty to the building. In the past, wooden doors and windows were used. In order to achieve the harmony and consistency of the doors and windows with the building appearance, most of the doors and windows showed that the paint was sprayed, and the paint was easily aging and peeling when exposed to ultraviolet rays. Later, color was invented. Aluminum doors and windows are expensive. Plastic steel doors and windows solve these problems well and are well received by users.
