It is understood that all kinds of alloys made of aluminum and various metal elements have incomparable advantages compared with other materials. They are light in weight and high in strength, and can be extruded into various new complex section materials used in various periods. Experts predict that although the market performance of aluminum alloy doors and windows is weak under the impact of low-grade products in recent years, driven by the development of real estate industry, aluminum alloy doors and windows will still be the mainstream in the future due to their corrosion resistance, small deformation, strong fire resistance, long service life, environmental protection and energy saving.
Improve the energy saving of doors and windows and expand the use space
Aluminum alloy doors and windows have become the main building doors and windows products in China due to their light weight, high strength, good performance, strong decoration, economic durability, pollution-free, and can be recycled and reused. They are widely used from high-grade public buildings to general civil residential buildings and industrial plants. However, the biggest defect of ordinary aluminum alloy doors and windows is the poor energy-saving effect. In order to solve this problem, many manufacturers have started the research and development of thermal insulation aluminum profiles, and more than a dozen manufacturers have produced various types of thermal insulation aluminum alloy profiles, which completely solves the problem of energy-saving of ordinary aluminum alloy doors and windows, and gives new vitality to aluminum alloy doors and windows, Aluminum alloy doors and windows are gradually replacing ordinary aluminum alloy doors and windows.
Aluminum alloy profile will still be the mainstream of the market
The information from the European door and window exhibition held in Nuremberg, Germany shows that the profile of doors and windows is slightly innovative. There are many cavities of aluminum alloy profiles, and the thickness is generally greater than 3 mm, which makes the energy-saving effect of doors and windows better and the mechanical properties of doors and windows are better. Most aluminum alloy profiles are equipped with heat break bridges. From the perspective of the use of profiles, there are flat flip door and window profile, push-pull flip door and window profile, roof window profile, gauze door and window profile, shutter profile, ventilation and heat dissipation network profile, hollow door panel profile, solid door panel profile and fixed window profile. Door and window glass occupies a large area in doors and windows, the quality of glass directly affects the quality of the whole door and window. The thickness of windows and doors in Europe is more than 5 mm, generally double-layer glass or insulating glass, and the interval between the two glasses is greater than 15 mm, so the energy-saving and sound insulation effects of doors and windows are better.
According to the prediction of relevant experts, aluminum alloy profiles in China will become the mainstream of the market in the next few years. Aluminum alloy doors and windows to high-tech, multi-functional development, first of all, aluminum profiles, glass and other new, high requirements, to meet the needs of the development of new aluminum doors and windows.
