What is Perforated Metal?

The process of perforation often refers to cutting or punching small patterned holes into a material. While many people are familiar with perforated paper products, some would be surprised by how often Perforated Metal is part of our daily lives. It is becoming more popular to transform plain sheet metal into functional and eye-catching perforated metal due to its benefits and the relative ease of conversion technique.

What was once a rudimentary and uncertain practice has now become standardized and efficient. The current standard methods of making perforated metal are laser, rotary pinned, and, the most common method, punch press.

You can perforate several metal materials, including:

  • Stainless Steel
  • Aluminum
  • Copper
  • Galvanized Steel
  • Titanium
  • Brass
  • Bronze

Perforated Metal also comes in varying hole types, such as round holes, square holes, slotted, hexagonal, and decorative patterns.

Not only does Perforated Metal bring strength and style to structures, but it also serves as both functional and decorative. Primary uses of this metal product include light control, sound control, ventilation, and filtration, among others.

Benefits of Stainless Steel Perforated Metal

You can choose from a variety of materials for Perforated Metal. However, there are several benefits to choosing a stainless steel option.

Stainless Steel has a high strength-to-weight ratio, allowing reduced material thickness that yields considerable cost savings. Additionally, stainless steel contains elements that offer corrosion-resistant benefits, particularly to fire and heat, and liquids containing chlorides. Stainless steel comes in numerous grades that can form into Perforated Metal sheets. Here are some examples of the advantages when opting for Stainless Steel material for projects requiring Perforated Metal.

Corrosion Resistance to Elements

Stainless Steel is a popular choice for various applications, such as walkway gratings and security infill panels. It contains chemical elements like Chromium, Nickel, and Molybdenum in its alloy, providing excellent corrosion resistance. Stainless steel Type 316, specifically, demonstrates higher durability against corrosive elements. It is especially strong against Chlorides found in seawater, pool water, and de-icing salts.

Note that Stainless Steel can become susceptible to corrosion if it comes in contact with carbon or plain steel. Therefore, it’s a good idea to keep carbon steel far away from any stainless steel varieties.

It's Decorative

Stainless Steel is not only durable; it's also decorative!

For example, Stainless Steel has become an attractive option for home appliances. It is often a top upgrade choice for cabinet inserts during new home builds or home renovations. Perforated Metal sheets can add a unique look to any space, whether it’s indoor or outdoor or commercial or residential.

McNICHOLS® Stainless Steel Perforated Metal comes mill finish, but you can polish or finish it to achieve the shine you'd expect when you hear stainless steel.

Because Stainless Steel is so durable and resistant to corrosion, it will maintain its appearance for longer than other materials. You can also customize steel perforated metal sheets in a variety of patterns and shapes to fit your design needs.

Perforated Metal panels create privacy without making people feel confined.

These distinct panels can divide workspaces without isolating the individual areas and allow for visibility and airflow. The panels will also absorb sound and echoes, keeping workspaces quieter.

Your employees or guests will appreciate the extra privacy without the feeling of being shut off from the rest of the area.

Noise Reduction

Perforated Metal panels work to reduce noise by dispersing sound waves. This effect applies to indoor and outdoor spaces and can keep areas quieter—likely appreciated by both guests and employees.

In some industrial settings, perforated metal is often used for wall or ceiling cladding to dampen or disperse sound, particularly for massive units like power generators.


Perforated Metal panels can improve ventilation by improving airflow. You can use them as sun protection screens to enhance the shade.

Installation of these panels can save money on heating and cooling costs and other costs that you might incur when attempting to improve ventilation in your space.
