Color aluminum (pre-coated aluminum alloy plate) has become the preferred material in the field of modern curtain wall due to its lightweight, high weather resistance and diversified design. The following are the core advantages and typical application scenarios:

1. Core advantages

Lightweight and high-strength performance

The density of color aluminum is only 1/3 of that of steel (2.7g/cm³), and the tensile strength is 180-300MPa, which greatly reduces the building load and is suitable for super high-rise or large-span curtain wall design. For example, the Shanghai Tower uses color aluminum honeycomb panel curtain wall to achieve a 30% structural weight reduction while meeting the wind pressure resistance requirements.

Excellent weather resistance and corrosion resistance

The surface is treated with fluorocarbon spraying or PVDF coating, resistant to ultraviolet rays, acid rain and salt spray corrosion, with a color difference ΔE≤1.5 (10-year outdoor test), suitable for coastal or industrial pollution areas. The curtain wall of Terminal T3 of Shenzhen Bao'an International Airport uses color aluminum panels, which have no significant fading in 15 years in a humid and hot marine climate.

Flexible aesthetic expression

Supports 30+ surface effects such as metal brushing, imitation wood grain, gradient color, etc., and can customize curved and special-shaped panels to meet the personalized needs of commercial buildings. For example, the Hangzhou Asian Games E-sports Hall uses gradient color aluminum curtain walls to create dynamic light and shadow effects.

Green environmental protection and convenient construction

Aluminum alloy is 100% recyclable, and carbon emissions in the production process are 40% lower than traditional curtain wall materials. Modular design supports dry hanging installation, shortening the construction period by 50%. Some curtain wall projects at Beijing Daxing Airport use pre-assembled color aluminum units, with an average daily installation of more than 800 square meters.

2. Typical application scenarios

Commercial complexes: curved color aluminum curtain walls enhance landmark recognition (such as the wavy facade of Chengdu Global Center).

Transportation hubs: high-speed rail stations and airports use the stain resistance of color aluminum to reduce maintenance costs (Guangzhou South Station case).

Cultural venues: Museums and theaters achieve a balance between artistry and durability through imitation stone color aluminum (Suzhou Museum West Hall).

Old renovation projects: The lightweight characteristics of colored aluminum avoid the need to reinforce the original building structure, such as the renovation of the facade of the historical building on the Bund in Shanghai.

Colored aluminum curtain walls continue to promote innovation in building skin technology through the characteristics of "light, beautiful, and long-lasting", and have significant potential in low-carbon cities and smart buildings in the future.
