Perforated aluminum sheet

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.

4. Price and Purchase Suggestions
Market prices vary depending on thickness (0.5mm-3.0mm), hole complexity,
and order quantity, with conventional product unit prices ranging from about
20 to 300 yuan per square meter. When purchasing, consider the following:
- Material Certification: Give priority to pure aluminum or high-quality
alloys to ensure corrosion resistance;
- Processing Standards: Check if the punched edges are smooth to avoid burrs
that could affect safety;
- Customization Services: For large projects, contact manufacturers (such as
Shanghai Mai Shi and Dali Aluminum Composite Panel) to customize hole
diameters and patterns as needed.
