Aluminum Alloys in Building Decoration

Building Aluminum Alloy Structure

• Spatial Grid Structures: High-strength aluminum alloy bars such as 6061 and 6082 can undergo extrusion into rods of various cross-sections for constructing large-span spatial grid structures. These structures find wide use in large public buildings such as stadiums, convention centers, and airport terminals.
• Bridge Engineering: Aluminum alloy bars are mainly used in the main beams and deck systems of small-to-medium span bridges, such as pedestrian bridges and scenic bridges. Compared with traditional steel, aluminum alloy bridges have advantages such as light weight, corrosion resistance, and low maintenance costs, making them particularly suitable for use in corrosive environments or situations requiring rapid construction.
• Power Towers: Power towers made of high-strength aluminum alloy rods have the advantages of being lightweight, easy to transport and install, and corrosion resistant. They are especially suitable for use in mountainous areas, islands and other areas with inconvenient transportation, which can reduce construction difficulty and cost.

Aluminum Alloy Door and Window Profiles

Aluminum alloy bars are extruded into window and door profiles, a primary material for building doors and windows. Compared to traditional materials, aluminum alloy doors and windows offer advantages such as light weight, high strength, corrosion resistance, and ease of processing. Furthermore, surface treatments like anodizing and fluorocarbon coating can achieve a rich variety of colors and textures to meet the needs of different architectural styles.

Aluminum alloy door and window profiles primarily use 6-series aluminum alloys, with 6063 and 6061 being the most commonly used grades. 6063 aluminum alloy possesses good extrudability and weldability, moderate strength, and excellent surface treatment properties, making it suitable for manufacturing main profiles such as door and window frames and sashes. 6061 aluminum alloy offers higher strength and is often used for components requiring higher strength, such as mullions and reinforcing ribs in doors and windows.

Building Aluminum Curtain Wall

Aluminum alloy rods are the main supporting material for building curtain walls, accounting for more than 95% of the metal rods used in curtain walls. 6-series aluminum alloy rods, such as 6061 and 6063, undergo extrusion and serve to manufacture structural components such as curtain wall joists, columns, and beams. These profiles are lightweight, high-strength, corrosion-resistant, and have good stability, enabling them to support panel materials such as glass, stone, and aluminum panels, with a service life of 50-100 years.

• Curtain Wall Keel System: Aluminum alloy bars are extruded and molded into columns and beams for the curtain wall, forming the curtain wall’s skeletal system. The columns, as the main load-bearing components, withstand wind loads, self-weight loads, and seismic loads; the beams connect the columns, forming a stable frame structure.
• Connectors and Fasteners: Aluminum alloy bars can be processed into various fasteners such as connecting brackets, adapters, and bolts, which are used to connect curtain wall panels and the keel system to ensure the overall stability of the curtain wall.
• Decorative Moldings and Edging: Through extrusion molding, aluminum alloy rods can be made into various decorative lines, edge trims, and molding strips for use in curtain wall finishing and decorative enhancement.

Building Aluminum Decorative Components

Aluminum alloy rods find wide use in interior decorative components, primarily for making ceiling joists, partition frames, decorative moldings, baseboards, and handrails.

Aluminum alloy decorative components offer advantages such as lightweight yet high strength, corrosion resistance, good fire resistance, easy cleaning, and convenient installation. They find wide use in kitchens, bathrooms, balconies, stairwells, and other interior spaces, boasting a long service life and low maintenance costs, meeting the dual demands of modern interior decoration for both aesthetics and functionality.

• 3003 and 6063 aluminum alloy rods can undergo processing, through extrusion molding, into decorative profiles with various complex cross-sections. After surface treatments such as anodizing, electrophoretic coating, or fluorocarbon spraying, they can present rich colors and textures, such as wood grain and stone-like finishes.

Aluminum Alloy Building Formwork

Aluminum alloy bars can also serve to make building formwork. Compared with traditional steel formwork, aluminum bar formwork has advantages such as light weight, easy assembly and disassembly, and high reusability. In large-span buildings, engineers can process high-strength aluminum alloy bars (such as 6061) into supporting structural components, replacing some of the steel, achieving lightweight construction while improving seismic performance. Aluminum bar formwork can reduce construction costs and improve construction efficiency, making it particularly suitable for high-rise buildings and large-scale engineering projects.

The application of aluminum alloy formwork not only improves construction efficiency and quality, but also achieves the goals of green construction and energy conservation and emission reduction, which is an important direction for the development of modern building industrialization.
