Perforated Metal Sheet is a punched metal product manufactured from carbon steel, stainless steel, aluminum, or galvanized steel sheets using precision punching processes. Classified as industrial and architectural perforated metal, it features uniform hole patterns for controlled airflow and strength. Perforated Metal Sheet is widely used for filtration, ventilation, screening, noise control, safety guarding, and façade applications in industrial facilities, commercial buildings, infrastructure projects, and decorative architectural designs.
