Who is more sought after in the aluminum alloy PK plastic steel doors and windows?

The industry knows that aluminum and various alloys made of various metal elements have advantages that other materials can't match. They are light in weight and high in strength, and can be extruded into various new complicated 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, the corrosion resistance, small deformation, strong fire resistance and use of aluminum alloy doors and windows 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, 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, due to 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 the foreign aluminum door and window factory is about to enter the market, many companies believe that consumers give up aluminum alloy mainly because they are not worried about the thinner and thinner aluminum materials. If they continue to have low quality and low price. 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 opportunity to join the WTO has 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 products, 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 surpassed 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 where the steel doors and windows are installed is more than 5 degrees per day than the room with the 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. Aluminum alloy is not the case, it will easily lead to surface oxidation and shorten the service life after corrosion.
