Standard profiles: These profiles are made of 1050, 1070, 3103 and 6060 aluminum alloys. They are available in reel and bar form and are manufactured to standardized shapes, sizes and dimensional tolerances.
These profiles are mainly used for door and window frames (facade structures). They are also useful in railings, balconies and other similar applications.

In the late 1980s, doors and windows were made of aluminum alloy profiles, which solved some of the shortcomings of steel windows. However, the profile itself is made of metal materials, and the heat and cold conduction is fast. The K value of the whole window of steel windows and aluminum alloy windows is above 6.0w/(m2.K), which does not fundamentally solve the problems of sealing and insulation. Although it can be equipped with hollow glass, the K value of the whole window can only reach about 4.5w/(m2.K).

Industrial aluminum profiles are an alloy material with aluminum as the main component. Aluminum materials with different cross-sectional shapes are obtained by hot-melting and extruding aluminum rods. However, the proportions of the added alloys are different. The mechanical properties of the industrial aluminum profiles produced are It is also different from the application field.

Aluminum alloy doors and windows are the first products to replace steel doors and windows. They are made of aluminum alloy extruded profiles for frames, stiles and fans. Ordinary aluminum alloy sliding doors and windows use aluminum alloy as the main material, and their sealing and sound insulation effects are better than steel windows. It is also easier to process than pure wooden doors and windows and steel doors and windows.
