Perforated Metal

Perforated metal sheet combines strength with open area for airflow, filtration, and a clean architectural look. We stock round-hole, square-hole, slotted, and decorative patterns (Grecian, Marietta, Cloverleaf, Octagon) in 304 and 316 stainless, aluminum, plain steel, galvanized, and copper.

Perforated sheet is used for architectural facades and sun screens, ventilation and speaker grilles, machine guards, acoustic panels, filtration, and infill. Hole sizes, center spacing, and open-area percentages are listed on every product page.
