The prominent advantages of extruded aluminum tubes in the application scenarios of the construction industry （一）

Extruded aluminum tubes have significant advantages in the construction industry, meeting the modern building's demands for lightweight, durability, aesthetics, and sustainability. The following are its outstanding advantages and specific application scenarios in the construction industry:

1、 Core advantages

Lightweight

The density of aluminum is only one-third of that of steel (about 2.7g/cm ³), and using extruded aluminum tubes can significantly reduce the weight of building structures, lower foundation loads, and reduce construction difficulty.

Case: The curtain wall support structure of high-rise buildings uses aluminum tubes instead of steel, reducing weight by more than 40%.

High strength and durability

Through alloying (such as 6061 and 6063 aluminum alloys) and heat treatment, the tensile strength can reach 200-350MPa, meeting the requirements of building structures.

Corrosion resistance: The surface natural oxide film (Al ₂ O3) can resist corrosive environments such as humidity and acid rain, extending its service life (up to 50 years or more).

Design flexibility and aesthetics

The extrusion process can produce aluminum tubes with complex cross-sections (such as hollow, multi cavity, thin-walled) to meet diverse design requirements.

Surface treatment: anodizing, powder coating, electrophoretic coating and other processes provide a variety of colors and textures to enhance the aesthetic appeal of buildings.

Convenient construction

Squeezed aluminum tubes are easy to cut, drill, and connect (such as bolts and riveting), simplifying the construction process and shortening the construction period.

Case: In modular buildings, prefabricated aluminum tube components can be quickly assembled.

Environmental Protection and Sustainability

Aluminum can be 100% recycled, and the recycling energy consumption is only 5% of the original aluminum production, which meets green building standards such as LEED and BREEAM.

Case: The application proportion of recycled aluminum extruded pipes in construction has been increasing year by year.
