Industry insiders predict that although the market performance of aluminum alloy doors and windows has been weak under the impact of low-grade products in recent years, due to the development of the real estate industry in the future, due to the corrosion resistance, small deformation, strong fire resistance and use of aluminum alloy doors and windows The characteristics of long life, environmental protection and energy saving determine that it is still the mainstream in the future market. Aluminum alloy doors and windows have become China's main architectural door and window products due to light weight, high strength, good performance, strong decoration, economical durability, no pollution, and can be recycled and reused. They are widely used from high-end public buildings to general residential houses and industries Plant. However, one of the biggest shortcomings of ordinary aluminum alloy doors and windows is the poor energy saving effect. To solve this problem, many manufacturers have begun the research and development of thermal insulation aluminum profiles, and more than a dozen manufacturers have produced various types. Thermal insulation aluminum alloy profiles completely solve the shortcomings of ordinary aluminum alloy doors and windows that are not energy-saving, and give new vitality to aluminum alloy doors and windows. Thermal insulation aluminum alloy doors and windows are gradually replacing ordinary aluminum alloy doors and windows. At present, in China's construction door and window product market, aluminum doors and windows account for the largest proportion, about 55%. With the vigorous development of China's construction industry in recent years, the output of aluminum alloy doors and windows continues to increase. China is a veritable country in the production of doors and windows. Doors and windows are divided into enclosure members or partition members according to their different positions. They have different design requirements. They have functions of thermal insulation, thermal insulation, sound insulation, waterproof, dustproof, fire prevention, anti-theft, etc. Strong decorative function. At present, energy saving is often required. For example, the heat loss caused by the gap between doors and windows in cold areas accounts for about 25% of the total heating energy consumption. The requirements for the tightness of doors and windows are also important contents that cannot be ignored in energy-saving designs. At the same time, doors and windows are also an important part of architectural modeling. Their shape, size, proportion, arrangement, color, shape, etc. have a great influence on the overall shape of the building. Doors and windows are designed to be strong and durable, flexible to open, tightly closed, easy to maintain, clean, etc., and their specifications should also meet the needs of industrialization of construction. Therefore, energy-saving, heat-insulating, strong and beautiful aluminum alloy doors and windows are the first choice.
