Perforated Metal

Perforated components make products work better with holes that function several ways: Holes that ventilate while they hold in radiation, holes that make your microwave oven safe but let you see what's cooking, holes that filter or select, holes that freely allow the passage of sound waves, gas or liquid for whatever good reasons you may have.
