Multi-layer structural creates ventilation for exterior walls by installing of covering elements. the aluminum keel structure screw to the building wall with strong brackets and anchoring elements, and aluminum wall panels to be installed and sealed as easy as lego blocks.

The air gap of multi-layer between the building and cladding provides natural ventilation, removing heat and moisture. It means summer cooler and winter warmer than single layer structural and improved energy efficient.

Aluminum is a lightweight material, approximately one-third the density of steel. This lightness makes aluminum profiles particularly popular in high-rise building curtain wall systems as it reduces the load on the building structure while providing sufficient strength and rigidity.

Aluminum exhibits excellent resistance to corrosion, able to withstand various environmental conditions including urban pollution, rain erosion, and other chemical attacks. This makes aluminum profiles an ideal choice for curtain walls in coastal and highly polluted areas.

Aluminum is easy to process and form into various complex shapes through extrusion, cutting, welding, and other techniques. This offers architects and designers great flexibility in design, enabling unique and innovative architectural appearances.

Aluminum profiles have good thermal break properties, effectively reducing thermal loss in buildings and enhancing energy efficiency. Additionally, aluminum is 100% recyclable, meeting the green building standards of modern architecture.

Aluminum profiles can undergo various surface treatments such as anodizing, powder coating, and electrophoresis, not only enhancing their durability but also providing a variety of colors and textures to meet different architectural styles.

Due to aluminum's resistance to corrosion and other physical properties, aluminum curtain wall systems generally require less maintenance. This is particularly important for commercial buildings, as reduced maintenance work can significantly lower operational costs.
