1/8 Perforated Aluminum Sheet
A 1/8 perforated aluminum sheet is a lightweight yet strong metal sheet with holes of 1/8 inch (3.175 mm) diameter. These sheets are widely used for ventilation, filtration, decorative designs, and industrial purposes.
Aluminum’s corrosion resistance and easy fabrication make it ideal for both indoor and outdoor use.
