Doors and windows are an indispensable and important part of buildings, and the sustainable development of the construction industry itself is also the decisive basis 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 periods of time affected by the international environment. change, but from a long-term perspective, the continued development of the construction industry for decades is certain. As a mirror reflecting 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 my country's building door and window product market, aluminum door and window products account for a large proportion, followed by plastic doors and windows, and steel door and window products.

Solid wood composite doors and windows, aluminum wood composite doors and windows are mainly concentrated in high-end real estate in economically developed areas, such as Beijing, Shanghai and other places. The door and window profiles used are different, the positioning grades are different, and the types and grades of door and window hardware accessories required in each area are also different. At present, the economically developed areas in China and the areas south of the Yellow River have a hot climate, and most of them use aluminum doors and windows. Due to the requirements of energy-saving policies, medium and high-end real estates use aluminum doors and windows with thermal insulation broken bridges, which play a role in energy saving and thermal insulation. Plastic doors and windows are mainly used in the severe cold and cold regions of Northeast, Northwest and North China.

After 20 years of development, various products have entered thousands of households. However, due to the rising prices of raw materials and the irregular behavior of some operators, the plastic door and window industry is now facing a severe test. The reason why aluminum alloy doors and windows occupy a large proportion of the market is that in the vast cities and towns in my country, aluminum alloy doors and windows have developed for a long time and a wide range. Although most of the aluminum doors and windows are still single-layer glass installed with ordinary aluminum profiles, such as aluminum doors and windows with broken bridge function and insulating glass, the proportion of the entire aluminum window market is still less than 20%, and aluminum doors and windows still occupy the building doors and windows products. Half of the market is Heshan. Plastic door and window products are emerging building door and window products developed under the support of national industrial policies.
