China has become the world's largest producer of aluminum alloy doors and windows and curtain walls. According to statistics, in 2004, China produced 240.9316 million square meters of aluminum alloy doors and windows and 40.642 million square meters of curtain walls. Through the rapid development in recent years, the curtain wall profession in China has been adhering to the development path of skill innovation. By opening up the market, introducing foreign advanced skills and developing new products, the curtain wall profession has entered the standard stage of market adjustment.
According to Huang Qi, director of the aluminum doors, windows and curtain walls Committee of China's Construction Metal Structure Association, six major features have been formed in the construction of aluminum alloy doors and windows and curtain walls in China: the construction and application skills of point connection curtain wall are in the forefront of the world, and Beijing New Poly The construction area, maximum span and construction difficulty of curtain wall of buildings and Zhongguancun civilized commercial building are all in the leading position in the world. After several years of development, energy-saving aluminum alloy doors and windows products have begun to establish energy-saving windows and doors skill system with Chinese characteristics, forming a certain ability of energy-saving doors and windows planning, production and construction It is enough to satisfy the basic requirements of building energy-saving doors and windows at that time; the unit curtain wall skills are widely used in China. This kind of curtain wall plate planning and construction skills with accurate processing technology and convenient construction are now mastered by large-scale domestic curtain wall enterprises. Ten years ago, it was only used in a small number of large-scale projects planned by foreign countries. Now, large-scale curtain wall projects such as Beijing, Shanghai and Shenzhen have been widely used ；
The application of a variety of new curtain wall facing materials in the construction of curtain wall projects has promoted the development of new-type curtain walls, increased the diversification of curtain wall products, and greatly mobilized the building engineers' interest in various new-type curtain wall facing materials. Marble curtain wall, clay board curtain wall, ceramic tile curtain wall, resin wood fiber reinforced cement board curtain wall, etc., the application of new curtain wall data and skills has greatly enriched the connotation of building curtain wall, and has a broad prospect; the theory of double curtain wall planning skills has gradually established at the beginning of occupation, and many large-scale curtain wall projects have planned internal and external circulation systems, and enterprises and professional scientific and technical personnel have now established The construction of large-scale curtain wall shading system has attracted the attention of architects, and the market of large-scale wing panel curtain wall shading system has gradually expanded with the construction of "hot summer and warm winter" area.
The standard system of aluminum alloy doors and windows and curtain wall construction in China has begun to be established. The national standards and specifications have been established from the aspects of product planning, production and processing, construction equipment, engineering inspection and inspection, and then the product engineering quality of doors, windows and curtain walls is guaranteed. With the implementation of these norms, the profession will be shuffled to survive the fittest, some small enterprises will be screened out, and the use of new data and the realization of energy-saving function will become an important growth point for the next step of career development.
