For the current market pattern of China's building doors and windows products, Huang Qi, director of the aluminum doors and windows curtain wall Committee of China Building Metal Structure Association, presented the statistical data of Du Zonghan, President of the China building metal structure association not long ago. According to this authoritative data, aluminum doors and windows products account for the largest proportion in China's building doors and windows market, accounting for 55%, followed by plastic products Material doors and windows, accounting for 35%; steel doors and windows products account for 6%; other materials products account for the remaining 4%. In terms of production, director Huang only disclosed the number of aluminum doors and windows products, about 150 million square meters.
From the point of view of the director of the special committee, Huang Qi station pointed out that the reason why aluminum alloy doors and windows occupy the largest market share is that in the vast cities and towns of our country, the development of aluminum alloy doors and windows products has a long time and a wide range.
Although the quality of aluminum alloy products has been questioned by the common people in a certain period of time or in some areas, due to the limited living standard of the domestic people and the restriction of economic conditions, aluminum doors and windows are still their preferred products among a considerable number of consumers.
Although the vast majority of aluminum doors and windows are still ordinary aluminum profiles with single-layer glass, for example, the aluminum doors and windows with hollow glass with bridge breaking function account for less than 20% of the total aluminum window market, and aluminum doors and windows still occupy half of the market of building doors and windows.
In view of the problem of 6% of the steel door and window products, Huang Qi explained that some fire doors, factory doors, including security doors and color steel plate production, all belong to the steel door products. In addition, due to the use of steel windows in some rural areas, the solid web steel windows or open web steel windows seen in the past are still produced in some areas, but the number is not very large.
Plastic door and window products are new building doors and windows products developed under the support of national industrial policy. After 20 years of development, a variety of products have entered thousands of households. However, due to the rising price of raw materials and the non-standard behavior of some operators, the plastic door and window industry is facing a severe test.
In recent years, ordinary consumers are faced with the topic of aluminum and plastic door and window products published by real estate developers and some architectural design departments. Isn't it? Earlier aluminum alloy doors and windows just came out, compared with the earlier solid web steel windows and open web steel windows, light and beautiful decoration really attracted many consumers' attention. However, with the passage of time, spring, summer, autumn and winter wind, frost, snow and rain test, the original aluminum alloy doors and windows disadvantages exposed, especially the strong thermal conductivity, poor thermal insulation shortcomings make people complain.
Later, plastic doors and windows appeared, and it was another upsurge of consumption. Plastic doors and windows were once one of the indispensable products for high-end residential decoration. But good flowers do not often open, good times do not often exist, at the beginning of a good new product, even into the dilemma of two ends. If the price of raw materials rises, the price of products will fall, otherwise consumers will leave. In addition, aluminum alloy doors and windows made a comeback, with hot bridge breaking technology and color appearance, coupled with insulating glass, solved many performance defects, and has become a synonym for high-grade doors and windows.
So who is better and who is worse? In the face of this question, Huang Qi's view is very simple: "two kinds of products have their own advantages and disadvantages. We can't judge one from the other. As long as we do well, we can become good products.". Based on what he has seen and heard abroad, he said for example: "influenced by economic conditions and people's living habits, the products of building doors and windows vary from country to country. In countries like Italy and Spain, there are few plastic doors and windows, but there are many in Germany, especially after the merger of the two countries. Generally speaking, plastic windows are mostly used in residential buildings, while aluminum windows are mostly used in public buildings.
