Doors and windows are an indispensable part of the building, and the sustainable development of the construction industry itself is also the decisive foundation for the development of building doors and windows. China is in a period of rapid economic development, although there are intermittent policy adjustments and short-term changes affected by the international environment., But from a long-term point of view, the sustainable development of the construction industry within decades is certain. As a mirror of the dynamics and trends of the construction industry, the door and window industry has both opportunities and challenges based on the background of the construction industry.

This year, in China's building doors and windows products market, aluminum doors and windows products accounted for a large proportion, followed by plastic doors and windows, steel doors and windows products.

Solid wood composite doors and windows, aluminum wood composite doors and windows are mainly concentrated in economically developed areas, such as Beijing, Shanghai and other places of high-end real estate. The door and window profiles used are different, the grades of positioning are different, and the types and grades of door and window hardware accessories required by each region are also different. At present, the domestic economically developed areas and areas south of the Yellow River, the climate is hot, most of the use of aluminum doors and windows. Due to the requirements of energy-saving policies, high-grade buildings use thermal insulation broken bridge aluminum doors and windows, play the role of energy-saving insulation. In the northeast, northwest, North China cold cold areas are mainly used plastic doors and windows.

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 irregular behavior of some operators, the plastic door and window industry is facing a severe test. The reason why aluminum alloy doors and windows occupy a large proportion of the market share is that in the vast cities and towns of our country, the development of aluminum alloy doors and windows products is long and wide. Although the vast majority of aluminum doors and windows are still ordinary aluminum profiles with single-layer glass, aluminum doors and windows with hollow glass function account for less than 20% of the total aluminum window market, and aluminum doors and windows still occupy half of the building door and window product market. Plastic doors and windows products are emerging building doors and windows products developed under the support of national industrial policies.
