Specific advantages of aluminum profiles
-
First, strong plasticity:
Aluminum alloy profile is metal material, aluminum adds all sorts of metal element to make all sorts of alloy, have other alloy profile incomparable advantage is: quality is light and strength is high, can extrude all sorts of complex section profile, satisfy all sorts of new section requirement of door window stylist.
Two, good airtight performance:
Broken bridge aluminum alloy profiles have strong air tightness, water tightness, heat insulation and sound insulation properties, which are suitable for various specific applications in the door and window industry.
Three, long service life:
Aluminum alloy profiles have the advantages of light weight, high strength, corrosion resistance, small deformation, strong fire resistance, long service life (more than 50 years).
Four, environmental protection and energy saving:
The broken bridge aluminum alloy profile adopts nylon 66, a new heat insulation material, forming a cold and hot bridge between the internal and external profiles, so as to minimize the heat conduction of aluminum alloy, heat insulation, sound insulation effect is good.
Five, good weather resistance:
Aluminum alloy profile after a variety of processing, the surface has acid, alkali erosion and not by air pollution, acid rain, ozone attack.Uv resistance, long-term maintenance of inherent color and luster.
Six, elegant decorative effect:
The surface of aluminum alloy profiles can be treated with various surface treatments, such as powder spraying, anodic oxidation, electrophoretic painting, wood grain transfer processing and other surface treatment technology, a variety of colors and wood grain, a large choice, can meet the needs of various architectural decoration, to the building covered with beautiful clothes.
