What is Perforated Metal?

Perforated metal is manufactured by using punches or presses to create a series of holes, slots, bars, or decorative patterns in sheet metal. In earlier times, these sheets would have to be designed by skilled laborers using manual hand tools, but thanks to advancements in modern technology, perforated sheet metal can be produced using a variety of machining methods.
