Relevant data show that China is the world's largest market for doors and windows. In addition to traditional aluminum alloy doors and windows, the development of plastic doors and windows is also in full swing. According to the current market share of plastic doors and windows, there are about 175 million square meters of plastic doors and windows every year. However, China's plastic door and window industry is very large, but its output value is not high. The main reasons are the following three points.
Consumption concept needs to be changed
At present, when Chinese buyers buy a house, they are mainly concerned about the qualifications of developers and builders, as well as the quality of the building, and they pay less attention to door and window buyers. On the one hand, it is due to people's lack of knowledge about doors and windows, and on the other hand, they always think that doors and windows are accessories of houses, and their quality has little effect on quality. But in foreign countries, there is a popular saying: Whether the housing is good or not, the key is to look at the doors and windows.
Home buyers in the United States often ask for what kind, what material, and what kind of standard doors and windows the construction uses. For commercial houses with a price of 10,000 yuan per square meter, the price of supporting doors and windows abroad is generally about 1,000 yuan per square meter, while in my country, it is only about 300 yuan per square meter. This shows that the quality and level of doors and windows in our country are generally low.
Vicious competition is serious
Because plastic doors and windows have many incomparable advantages over other materials, my country lists plastic doors and windows as one of the country's key building materials. Therefore, in the past 10 years, the production and application of plastic doors and windows in my country has achieved rapid development, but due to the overheating of the development, it has caused a serious situation of oversupply.
At present, the annual market demand for plastic doors and windows in my country is about 1.5 million tons, while the annual production capacity of plastic doors and windows has reached 3 million tons. Frequent occurrences have greatly affected the reputation of plastic doors and windows. The consequence of low-price competition has also caused my country's entire plastic door and window industry to be at a loss.
Du Zonghan said that although my country's plastic doors and windows currently account for a considerable market share, there is still a certain gap compared with foreign developed countries. According to statistics, the current average market share of plastic doors and windows in Europe is 40%, the market share of plastic doors and windows in Germany has reached 54%, and the United States has reached 45%. In terms of building energy consumption, the total energy consumption per unit of residential buildings in my country is about 3 times that of developed countries, the energy consumption of exterior windows is 1.5 to 2.2 times that of developed countries, and the air leakage rate of doors and windows is 3 to 6 times that of developed countries. This shows that there is still a large gap between my country's building energy conservation level and foreign developed countries.
Disorganized industry standards
According to Chairman Du, my country currently does not have an industry standard for doors and windows that match the price of houses. Usually, the five major performances of doors and windows are wind pressure resistance, air leakage performance, rainwater permeability, thermal insulation performance, and sound insulation performance. The requirements are often just that the samples submitted for inspection can be qualified, and the pass rate of doors and windows after the house is built is low.
