What Is Perforated Sheet Metal?

Perforated metal is a piece of sheet metal that has been stamped, fabricated, or punched to create a pattern of holes, slots, and various aesthetic shapes. A wide range of metals is used in the perforating metal process, which includes steel, aluminum, stainless steel, copper, and titanium. Though the process of perforating enhances the appearance of metals, it has other useful effects such as protection and noise suppression.

The types of metals chosen for the perforation process depend on their size, gauge thickness, types of materials, and how they will be used. There are few limitations to the shapes that can be applied and include round holes, squares, slotted, and hexagonal, to name a few.
