[China Aluminum Industry Network] Summary: With the booming development of China's construction industry in recent years, the output of aluminum alloy doors and windows is increasing. According to statistics from the Aluminum Doors, Windows, Doors, and Curtain Wall Committee of China Construction Metal Structure Association, the output of aluminum doors and windows in China was 2.8 in 2003. Billion square meters, in 2005 it was 320 million square meters, and in 2007 it was 365 million square meters. It can be seen that China is a veritable country with big doors and windows.

With the booming development of China's construction industry in recent years, the output of aluminum alloy doors and windows continues to increase. According to statistics from the Aluminum Doors and Windows Curtain Wall Committee of China Construction Metal Structure Association, the output of aluminum doors and windows in China was 280 million square meters in 2003 and 320 million in 2005. In terms of square meters, it was 365 million square meters in 2007. It can be seen that China is a veritable country with a large number of doors and windows. In the large-scale curtain wall enterprises, the production rate of unitary curtain walls has accounted for about 60% of the curtain wall of the frame type. The proportion of double curtain wall projects has increased significantly. This is not only the demand for curtain wall enterprises, but also reflects the construction of all walks of life in the country. Overall improvement of the overall awareness of energy conservation. Among them, Shenyang Yuanda curtain wall company's total sales in 2008 totaled 18 billion yuan, an increase of 17% year-on-year; Shenzhen Jinyue Curtain Wall Company undertook the curtain wall projects of special high-rise buildings such as Guangzhou TV Tower and Guangzhou West Tower, and accumulated the high-rise curtain wall engineering design and construction for China. Experienced.
In terms of output, China is undoubtedly a major country in the use and manufacture of aluminum doors and windows. As the external protective structure of the doors and windows, the quality of the project is particularly important. At this annual meeting, Yao Bing, Chairman of the China Construction Metal Structure Association, views the new concept of project quality and the innovation and development of the door and window curtain wall industry. The intrinsic link between the quality of the project and the aluminum curtain wall was elaborated. Yao Bing believes that doors and windows curtain wall as a building external protection structure should also have a reasonable service life, should be updated in due course; the quality of doors and windows curtain wall is closely related to the overall building; doors and windows curtain wall enterprises should be fully innovative on the existing basis.
Doors, windows, and curtain walls should have a reasonable life expectancy Yao Bing said that any building has a long life span, civil construction is 50 years, and important construction is 100 years. Beijing has formulated a reward system specifically for project structures, stating that the structure is crucial to the quality of construction projects. The building's curtain wall is not only a decoration. It is a building external protection structure and is an important part of the building structure. Doors, windows, and curtain walls must have a reasonable lifespan as the external protective structure of the building.
In the 1980s, aluminum alloy doors and windows and building curtain walls in China were in their infancy. Some building curtain wall projects were copied from Germany, Italy, Japan, and the United States. Later, some people raised the problem of light pollution from glass curtain walls. After the 1980s, a number of large-scale public buildings began to use a large number of building curtain walls. The use of facade decorative materials has also undergone major changes. Large-area all-glass curtain wall projects It is also gradually decreasing. At this time, there is not too much noise to hear light pollution. This period is a new era for the replacement of the building's curtain wall, and it is also an era in which the curtain wall will be completely renewed. Yao Bing proposed that he is more worried about the projects of the 1950s before last century. The structure is prone to problems, even including reinforced concrete high-rise buildings, and he fears that one day it will suddenly fall down. Therefore, the building of windows and doors as a very important building product, there is also a problem of upgrading.
Disaster prevention capability is an important factor in measuring the quality of building structures. Buildings cannot but consider disaster prevention. For example, the Wenchuan earthquake last year caused serious damage to buildings. The earthquake is a destructive experiment conducted by nature on the building structure. We cannot do such a destructive experiment at ordinary times. There is also a typhoon. China is a multi-typhoon country, and coastal areas have relatively high requirements for the wind pressure resistance of doors and windows. Waterproofing doors and windows is an important issue. In the more economically developed regions, with the increase of productivity, the use of building curtain walls is relatively more, and the requirements for construction are even higher. In the coastal areas, typhoons and tsunamis are constantly testing our buildings. In 1988, a typhoon landing in Guangdong's Shantou area caused many aluminum doors and windows to be damaged. At that time, our country’s aluminum doors and windows were not strictly regulated, and some projects used thin aluminum alloys. Materials, doors and windows made of 0.8 mm aluminum profiles certainly could not withstand the typhoon. After this incident, China’s aluminum doors and windows have increased the requirements for aluminum wall thickness, and the quality of aluminum doors and windows has been significantly improved.
Door and window walls should have a long life
