Perforated stainless steel is a dynamic material that practically pays for itself over time. It excels in both high-end and industrial settings by bringing strength and style to many different settings.

Depending on your application and need, every specification matters. So, what are some of the most important considerations when you are looking at Stainless Steel Perforated Metal as an option?

In this blog, we share more about Stainless Steel Perforated Metal and why it may be the right choice for your business needs, regardless of your industry.

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.

Several metal materials can be perforated, including:

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

Perforated metals also come in varying hole types, such as round hole, square hole, 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, filtration, among others.

Benefits of Stainless Steel Perforated Metal

When it comes to perforated metals, you can choose from many materials. 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

Because stainless steel contains chemical elements like Chromium, Nickel and Molybdenum in its alloy, this material is a popular choice for applications, such as walkway gratings to security infill panels, due to its corrosion resistance. Stainless steel Type 316, specifically, demonstrates higher durability against corrosive elements, especially Chlorides found in seawater, pool water and de-icing salts. Note that stainless steel can become susceptible to corrosion if it’s cross-contaminated with carbon or plain steel, so, it’s a good idea to keep carbon steel far away from any stainless steel varieties.

It's Decorative

Stainless steel isn't just durable, it's also decorative!

For example, stainless steel has become an attractive option for home appliances and 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 can be polished or finished to have that shine you'd expect when you hear the words stainless steel.

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

Perforated 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 panels work to reduce noise by dispersing sound waves. This effect applies to indoor and outdoor spaces and can help 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 panels can improve ventilation by improving airflow. They can be used as sun protection screens to increase 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.
