Perforated Aluminum Sheet: The Versatile Decorative Material of Modern Architecture
1. Definition and Material Characteristics
Perforated aluminum sheet is a metal sheet made of aluminum alloy, formed with regular or irregular holes through CNC punching technology. Common hole shapes include round holes, square holes, and diamond-shaped holes. It is lightweight (with a density about one-third that of steel), corrosion-resistant, fireproof, moisture-proof, and recyclable, aligning with green building concepts.
2. Core Advantages
Ventilation and Heat Dissipation: The hole design ensures air circulation, suitable for air conditioner locations and equipment protective covers that require heat dissipation, effectively prolonging equipment life.
Sound Absorption and Noise Reduction: By adjusting the hole diameter and arrangement density, it can be used as a sound-absorbing wall panel or ceiling, suitable for theaters, office buildings, and other acoustically sensitive spaces.
Aesthetics and Design Sense: The metallic texture combined with the light and shadow effects of the holes gives the building facade a dynamic layer of depth. Examples include Zaha Hadid's curved curtain walls and the wavy exterior of the Munch Museum in Norway.
Durability and Maintenance: Surface treatment processes (such as fluorocarbon coating and film covering) enhance UV resistance and weather resistance, with an outdoor service life of up to 20 years, and are easy to clean.
3. Application Scenarios
Building Facades: As curtain wall material, it has both sunshade and decorative functions. For example, the Hongkou District project in Shanghai used 1.0mm perforated aluminum sheets to achieve a lightweight design.
Indoor Decoration: Used for ceilings and partitions, such as aluminum ceiling panels that are resistant to smoke and moisture, suitable for kitchens and bathrooms.
Functional Structures: Such as computer room sound-absorbing panels and shopping mall signage decorative panels, with customizable hole diameters to meet light transmittance and breathability requirements.
