What is an aluminum curtain wall?

Aluminum Curtain Wall Material and Structure

Aluminum curtain wall is an exterior wall decoration system with aluminum alloy plate as the core material, usually composed of the following parts:

Panel: High-strength aluminum alloy plate (such as 3003, 5052 series) is generally 1.5-4.0mm thick, and the surface can be processed into plane, arc, punching or carving shapes.

Frame: It is composed of aluminum alloy profiles (such as square tubes and angle brackets) and fixed to the main structure of the building by welding or bolts.

Connectors: Including angle brackets, screws, sealing strips, etc., to ensure the stability and sealing of the curtain wall.

Surface treatment: Fluorocarbon spraying, powder spraying or anodizing process is used to give the aluminum plate excellent weather resistance and decorative properties.

Core Features and Advantages of Aluminum Windows For Curtain Wall

Lightweight and high strength:

The density of aluminum plate is only 1/3 of that of steel, which greatly reduces the building load. At the same time, the tensile strength reaches 100-280MPa, and it has excellent earthquake and wind resistance.

Weather resistance and corrosion resistance:

Fluorocarbon coating can resist UV rays, acid rain, and salt spray erosion, with a service life of more than 20 years, especially suitable for coastal and industrial pollution areas.

Flexible shape:

It can be processed into complex curved surfaces (such as hyperbolic surfaces and twisted shapes) through stamping, bending, welding and other processes to meet the needs of modern buildings for streamlined design.

Environmentally friendly and recyclable:

Aluminum can be 100% recycled and reused, and the production energy consumption is only 5% of steel, which meets the green building standards.

Low maintenance cost:

The surface is smooth and not easy to accumulate dust. The fluorocarbon coating is self-cleaning. Daily cleaning only requires neutral detergent and soft cloth.

Aluminum Windows For Curtain Wall Application Scenarios

High-end commercial buildings:

Such as the facade decoration of office buildings and shopping centers, highlighting the sense of modernity and technology (such as the hyperbolic aluminum curtain wall of Nanjing Zhongning Mansion).

Cultural landmarks:

Public buildings such as museums and theaters often use perforated aluminum plates or carved aluminum plates, taking into account both lighting and artistic effects (such as the gradient triangle hole design of Suzhou Jinhuyuanzhu).

Transportation hubs:

Large-span spaces such as airports and high-speed rail stations use the lightweight characteristics of aluminum curtain walls to reduce structural burdens (such as curved aluminum plates wrapped around columns in subway tunnels).

Residential and villas:

Imitation wood grain and imitation stone aluminum plates replace traditional materials, reducing maintenance costs and improving fire resistance (such as imitation wood grain aluminum plates for high-end residential exterior walls).

Maintenance and maintenance

Regular cleaning:

Rinse the surface with clean water every quarter, and use neutral detergents (such as detergent) for stubborn stains to avoid strong acid and alkali corrosion of the coating.

Check the sealing:

Check the sealing strips and drainage grooves every year to prevent rainwater leakage from corroding the aluminum plate.

Avoid mechanical damage:

It is forbidden to scratch the surface with hard objects, and the perforated aluminum plate needs to clean the dust accumulated in the hole regularly.

Professional maintenance:

A professional team is hired every 5 years to check the integrity of the skeleton connectors and coatings, and perform local repainting or reinforcement if necessary.

Special environmental treatment:

Anti-salt spray coatings need to be added in coastal areas, and PVDF fluorocarbon paint with stronger pollution resistance is recommended for industrial areas.
