Perforated corrugated aluminum panels are a type of metal building material that combines corrugated structure and perforation process, widely used in architectural decoration, ventilation, and noise reduction.
Perforated corrugated aluminum panels combine both functionality and aesthetics. They are made from aluminum sheets through two processing techniques: perforation and corrugation rolling.
Perforated corrugated aluminum panels are a design choice to enhance aesthetics in architectural applications. They are produced by forming machines—ordinary flat perforated sheets are processed into corrugated panels through a forming machine. In addition to their beautiful appearance, we also provide corrugated perforated panels with higher strength and better noise control.
The corrugated structure of perforated corrugated aluminum panels significantly improves the stiffness of the sheet (bending strength is more than 30% higher than flat sheets), while the perforation design provides ventilation, lighting, sound absorption, and shading functions.
Haomei Aluminum provides you with corrugated perforated panels in various metal profiles, hole patterns, and finishes. We also offer structural design, installation support, customization of open areas, and coil patterns, providing comprehensive support for any interior or exterior construction and renovation project.
Core Features and Advantages of Perforated Corrugated Aluminum Panels
- Lightweight yet strong: Aluminum sheets are inherently lightweight, but when rolled into corrugated shapes, their bending strength is significantly enhanced, reducing the load on building structures. While reducing self-weight, they also optimize load-bearing structures.
- Excellent durability: Aluminum alloy materials themselves have good anti-rust and corrosion resistance. After surface treatments such as powder coating (for both indoor and outdoor use) or fluorocarbon coating (especially suitable for outdoor applications), their weather resistance is further enhanced, maintaining rust-free and corrosion-free performance for over ten to twenty years.
- Outstanding decorative and customizable properties: This is one of their biggest highlights. You can customize the hole shape (such as round, square, or even special patterns), hole size, arrangement (straight row, 45° or 60° staggered rows, etc.), as well as different surface colors and textures (such as RAL color system coating, wood grain finish, etc.).
- Weather resistance: Aluminum alloy base material treated by anodizing or PVDF fluorocarbon coating can withstand extreme temperatures from -50℃ to 80℃, with a service life of over 25 years even in high-salt coastal environments.
- Lightweight design: Panels with thicknesses of 0.8-3.0mm weigh only 6-12kg/㎡, which is just one-third the weight of stainless steel, significantly reducing building loads.
- Acoustic performance: With a perforation rate of 15%-30%, the Noise Reduction Coefficient (NRC) can reach 0.7-0.9, suitable for noise-sensitive areas such as airports and subways.
Multiple Functions
- Ventilation and light transmission: Perforation design (round holes/square holes/slot holes, etc.) can adjust airflow and light transmission rate.
- Noise reduction and shading: Control sound wave reflection and reduce solar radiation impact through hole size and perforation rate.
- Security and weather resistance: Minimum hole diameter of 0.5mm can meet security requirements, while also offering corrosion resistance, fire resistance, and moisture resistance.
Environmentally friendly and recyclable
Aluminum sheets can be 100% recycled and reused, meeting green building standards.

Thickness Selection Guide
The higher the perforation rate, the lower the strength of the sheet, so thicker panels must be selected. When the perforation rate exceeds 50%, it is recommended to use aluminum sheets with a thickness of no less than 3.0mm to ensure flatness and strength. Deep corrugation designs can allow for thinner sheets without compromising strength, while shallow corrugations or flat designs require relatively thicker sheets to maintain strength.
