Hole Diameter: Ranges from tiny pinholes (around 0.5 mm) to large cut-outs (up to 20 mm or more), depending on ventilation or visual needs.
Pitch (Center-to-Center Spacing): Tighter pitch for finer filtration, wider pitch for airflow and aesthetics.
Open Area (%): Higher open area means more air/light passage—critical for HVAC, agriculture, and filtration use.
Sheet Thickness: Choose based on structural strength, from 0.4 mm to over 5 mm.
Material used for round hole perforation:
Stainless Steel: Corrosion-resistant, sleek, and long-lasting.
Aluminum: Lightweight and great for decorative use.
Mild Steel (Galvanized): Durable and cost-effective for industrial use.
Brass/Copper: Used in specialized or high-aesthetic applications.
Customization? Absolutely.
