How to choose perforated metal
A practical guide to selecting hole pattern, size, and material.
Hole patterns
Round, square, or slotted geometries and their open area percentages.
Sheet gauges & margins
Material thickness, blank borders, and flat-sheet tolerances.
Alloy selection
Carbon steel, stainless 304/316, aluminum, and protective finishes.
Perforated metal engineering guide
Select the right hole geometry, open area ratio, alloy, and sheet thickness for your mechanical, filtration, and architectural requirements.
Choosing hole size and pattern by application
The pattern orientation dictates fluid flow resistance, particle capture thresholds, and acoustic dissipation.
Round holes provide the smoothest media flow with minimal turbulence and clean backwash capability.
304 & 316L Stainless Steel
Balances acoustic damping, free airflow, and pressure drop while shielding internal mechanical units.
Galvanized Steel & Aluminum 3003-H14
Controls daylight diffusion and solar heat gain coefficients (SHGC) while maintaining structural panel rigidity.
Anodized Aluminum & Weathering Steel
