[Abstract]:
From the above analysis, plastic steel doors and windows and aluminum alloy doors and windows have their own advantages.

Aluminum and various alloys of various alloys have advantages that are unmatched by other materials. They are light in weight and high in strength, and can be extruded into various new complex cross-section materials used in various periods. Experts predict that despite the weak market performance of aluminum alloy doors and windows in the impact of low-grade products in recent years, in the future, driven by the development of the real estate industry, aluminum alloy doors and windows have low corrosion resistance, small deformation, strong fire resistance, and use. The characteristics of long life, environmental protection and energy saving determine that it is still the mainstream in the market in the future.

Aluminum alloy doors and windows were introduced in China in the early 1980s. Due to their unique advantages such as light weight and corrosion resistance, they gradually replaced the original steel windows and were favored by consumers. However, in the past two years, the domestic steel-steel doors and windows have developed rapidly, which has already had a significant impact on the market of aluminum alloy doors and windows. Some people think that the aluminum door and window frame has a strong thermal conductivity, which is not good for heat insulation, and plastic insulation can save energy. In response to this statement, the experts of the Aluminum Products Committee of the China Building Decoration Association believe that in fact, the heat insulation is mainly glass, not the problem of window frame materials.

Plastic-steel windows have traditionally been used in low-rise homes. This is because, on the one hand, there are problems such as aging and cracking of plastics; on the other hand, because of the gap between plastic and steel plate produced by domestically produced plastic steel, air and water can enter and gradually corrode the steel plate, and strength and rigidity cannot be guaranteed. Therefore, many plastic window frames are not straight at present, and often do not move and are difficult to open. In contrast, the unique advantages of aluminum alloys have long been recognized around the world, and can be used to make multi-functional doors and windows of various complex sections. The service life can be more than 50 years or even longer. It is difficult to replace general materials, and plastic steel doors and windows are impossible. match.

Under the dual pressure of plastic steel to seize the market and foreign aluminum door and window factory to enter the market, many companies believe that consumers give up aluminum alloy mainly because they are not worried about thinner and thinner aluminum materials. If they continue to have low quality and low price. The products will seize the market and will soon be eliminated by the market. To survive, enterprises must rely on high technology to speed up the development of new products and create their own brands as soon as possible. For example, in order to be able to insulate steel from plastics, companies can produce insulated aluminum alloy short bridge profiles to achieve the same thermal insulation as plastic steel windows. Insiders pointed out that the impact of plastic steel doors and windows has made domestic enterprises aware of the need for innovation and quality; the opportunities for joining the WTO have made them feel tremendous pressure and challenges. Large-scale aluminum alloy-type materials for door and window production, such as Northern International Xilin Aluminum, as the backbone of the industry, this year will be the road to quality service brand expansion, but also the high-tech, high-quality development of aluminum alloy doors and windows Year

As a new type of building product, plastic steel doors and windows have sprung up in the door and window market in the past two years, and the market share has greatly exceeded that of ordinary wood, steel doors and windows, color plate doors and windows, and directly pushes aluminum alloy doors and windows. More information shows that the next century will be the world of plastic steel doors and windows. By then, aluminum alloy doors and windows will retreat and enter the ranks of being eliminated. So, what are the advantages and disadvantages of plastic steel doors and windows and aluminum alloy doors and windows? We may wish to compare them by the following performance characteristics.

1, sound insulation performance According to the data, the sound insulation performance of plastic steel doors and windows is much better than aluminum alloy doors and windows.

For example, in buildings that meet the same noise requirements, the distance between the building where the aluminum alloy doors and windows are installed and the main road must be 50 meters away, and if it is made of plastic steel doors and windows, it can be shortened to within 16 meters.

2, thermal insulation performance

When it comes to thermal insulation, we need to compare the technical parameters of the material, for example, the thermal conductivity of PVC material is 0.14, while that of aluminum alloy is 175. That is to say, under the same conditions, in terms of material thermal conductivity, aluminum is 1250 times that of PVC material. Of course, if PVC is made into doors and windows and energy consumption is compared, it is difficult to generalize. Because the interior loses heat, it is usually associated with roofing, floors, walls, and doors and windows. However, scientific research shows that as an ordinary house, the air conditioner is also turned on, and the room with plastic steel doors and windows is more than 5 degrees per day than the room with aluminum alloy doors and windows.

3, corrosion resistance

Plastic steel doors and windows can resist the corrosion of acid and alkali and other chemical substances, so they are not afraid of urban environmental pollution, hydrochloric acid and acid rain. The aluminum alloy is not the case, it will easily lead to surface oxidation and shorten the service life after corrosion.

4, door and window installation performance and service life

Plastic steel doors and windows are much smaller than aluminum alloy doors and windows, and because of the overall shape, the installation speed is very fast, which greatly improves the overall work efficiency. In terms of service life, the normal service life of plastic steel doors and windows is 30 to 50 years, lower than aluminum alloy doors and windows.

5, product style and process performance

Plastic steel doors and windows and aluminum alloy doors and windows can be made into flat, push-pull, overhang and curved windows according to the design requirements of the designers. The shape is beautiful and novel. The surface of plastic steel doors and windows can be colored, coated, and multi-color co-extruded; the surface of aluminum alloy doors and windows can be sprayed, electrophoresed, and the color can be diversified.

6, pPlastic steel doors and windows and aluminum alloy doors and windows can be applied to various industrial and civil buildings. The price of ordinary plastic steel doors and windows is 200 to 500 yuan / square meter, the price of double-plastic steel doors and windows is more than 500 yuan / square meter, the price of high-grade plastic steel doors and windows It can reach 1,500 to 2,000 yuan / square meter. The price of ordinary aluminum alloy doors and windows is about 200 yuan / square meter, and the price of high-end products is about 500 yuan / square meter.

From the above analysis, plastic steel doors and windows and aluminum alloy doors and windows have their own advantages. Therefore, it is estimated that in the future for a long period of time, plastic steel doors and windows and aluminum alloy doors and windows will still be equally divided.
