        Aluminum alloy doors and windows made of aluminum alloy profiles are more and more popular among consumers. In the current market of door and window in China, aluminum alloy doors and windows have now gained a certain advantage in the whole door and window occupation, then, aluminum alloy profiles What are the detailed advantages?

        First, the plasticity is strong:

        Aluminum alloy profiles are metal materials. Aluminum is processed into various alloys to make various alloys. The unique advantages of other alloy profiles are: light weight and high strength, which can be extruded into various messy section profiles, satisfying door and window designers. Various new section requests.

        Second, the sealing function is good:

        Broken bridge aluminum alloy profiles have strong air tightness, water tightness, heat insulation and sound insulation. These functions are suitable for various detailed applications of doors and windows.

        Third, the application of long life:

        Aluminum alloy profiles have the advantages of light weight, high strength, corrosion resistance, small deformation, strong fire resistance and long service life (more than 50 years).

        Fourth, environmental protection and energy conservation:

        The aluminum alloy door and window profiles of broken bridges are made of new heat insulation materials, which form a cold and heat bridge between the inner and outer profiles, thus minimizing the heat conduction of the aluminum alloy and providing good heat insulation and sound insulation.

        5. Excellent weather resistance:

        The aluminum alloy door and window profiles are treated with various skills, and the appearance is resistant to acid and alkali corrosion and is not affected by air pollution, acid rain or ozone. UV resistant, long-lasting color and luster.

        Sixth, the decoration is elegant:

        Aluminum alloy door and window profiles can be processed in a variety of different appearances, such as powder coating, anodizing, electrophoretic coating, wood grain transfer processing and other external processing skills, a variety of colors and wood grain, choose a large space, can be satisfied All kinds of construction and decoration needs, aluminum alloy doors and windows for the construction of beautiful clothing.
