What is perforated sheet metal?

Perforated sheet metal involves two key elements: an existing piece of sheet metal, perhaps galvanised steel or stainless steel, and a tool that stamps, drills or otherwise punches a hole into that sheet. The end product is useful because it combines the strength and durability of flat sheets with a number of potential benefits offered by the holes stamped into the base layer. In architectural applications, a perforated metal sheet can offer a number of benefits, including:

• Privacy: Screening off the inside of a building from the outside or reducing visibility into an office or sensitive business area.
