What is Perforated
Aluminium Sheet?
Perforated aluminium sheet is produced by punching a regular pattern of holes into flat aluminium sheet using CNC punching machines. Being lightweight, corrosion-resistant and easy to fabricate, it's widely used where strength, ventilation and appearance all matter.
The most common pattern, offering a good balance of open area and structural strength. Suitable for general ventilation, filtration and screening use.
Provides a higher open area than round holes for the same spacing, often chosen for architectural facades and acoustic panels.
Elongated openings that allow higher airflow and are commonly used in ventilation grilles and decorative cladding.

Frequently Asked Question
Trusted in more than 100 countries and 4 million customers.
Construction, HVAC, automotive, interior design, signage and general industrial ventilation and filtration.
Round, square, slotted and decorative patterns, with custom hole size and pitch on request.
Yes, aluminium naturally resists corrosion, making it suitable for humid and outdoor architectural applications without additional coating.
Yes, perforated aluminium sheets can be finished with powder coating or anodizing for color and added surface protection.
Yes, we supply standard sheets as well as cut-to-size panels based on project drawings.
It depends on the application — acoustic and ventilation needs favor higher open area, while structural/architectural panels may prioritize strength. Our team can help you select the right spec.
