Architectural aluminum profiles are various products for construction engineering that are processed by cold bending, sawing, drilling, coloring and assembling of plates, strips, foils, tubes and profiles of aluminum and aluminum alloy materials. Building envelope, doors and windows and decoration works, etc.

Because the density of aluminum is 2.7g/cm3, it is only 1/3 of that of steel; its chemical properties are lively, it is easy to form a dense and firm oxide film with oxygen in the air, and it has good corrosion resistance in the atmosphere and water; Light and heat are highly reflective; the texture is flexible, shiny, easy to process, and can be colored or made into various texture patterns.

Aluminum is divided into two categories: pure aluminum and alloy aluminum. Pure aluminum has low strength and its use is limited. A small amount of alloying elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium and titanium, are added to pure aluminum. Aluminum alloys with different properties can be obtained, and their strength is significantly improved after cold working or heat treatment.

According to different production methods, aluminum alloys are divided into deformed aluminum alloys and cast aluminum alloys. Deformed aluminum alloys are divided into rust-proof aluminum alloys, hard aluminum, super-hard aluminum and special aluminum. In construction projects, plates, profiles and pipes made of industrial pure aluminum (L1-L6), rust-proof aluminum alloys (LF2, LF21, etc.) and forged aluminum (LD2) are generally used.

As a building product, aluminum profiles are mainly used for:

1. 1050, 1100, 3105, 5052 boards are used for the roof.

2. 1050, 1100, 3003, 5005, 5052, 6063 boards and profiles for residential, warehouse, factory, office, and store use.

3. 1100, 5005, 6063 boards and shapes for ceilings, inner walls and compartments.

4. 1080, 5052, 5N01, 6063 shapes and plates for ventilation holes, handrails and lighting.

5. 1050, 1100, 5005, 5052, 6063 plates and shapes for doors.

6. 5052 and 5182 plates for aluminum shutters.

7. 5052, 6063 shaped plates and plates for curtain and window rails.

8. 5052, 6063 boards, shapes and pipes for lattice doors and door leaflets.

9. 1100, 5052, 6063 profiles and plates for sliding windows.

10. 6063 profiles for window frames.

11. 5052, 6061, 6N01, 6063, 5056 boards, shapes, and wires for walls.

12. 5052, 6063, 6N01 profiles for aluminum profile balcony guardrails.

With the progress of aluminum processing technology and surface treatment technology. The consumption of colored aluminum sheets, composite aluminum sheets, high-grade door and window aluminum profiles and decorative sheets in economically developed countries is increasing year by year. Since the late 1980s, China has also achieved remarkable results in the scientific research, development and application of architectural aluminum profile products, and in the early 1990s, the first organic-coated color aluminum sheet production line was built.
