Perforated sheet and expanded metal both open up a surface for airflow, light, or visibility, but they're not interchangeable, and picking the wrong one can cost you time on a screen or panel project.
Perforated sheet starts as solid material with punched holes in a pattern, which gives you precise control over hole size, spacing, and open area. It's a common choice for architectural screens, filtration, and anywhere a clean, uniform look matters.
Expanded metal is slit and stretched rather than punched, which means no material is removed and the diamond pattern gives strength with less weight. It shows up a lot in security fencing, walkways, and industrial guarding where strength matters more than a precise pattern.
