choosing the right perforated material

Not all metals are the same; some are better suited than others for indoor and outdoor applications. When deciding which type of metal to use, consider how it will be used — decorative or functional. Indoor or outdoor? Below, learn more about choosing the right perforated material options and the advantages of each type of material.

 

Choosing the Right Perforated Material

Perforated metal is long-lasting and durable. Various coatings can be applied to enhance the appearance and improve longevity. Perforated metal can be used in multiple applications, such as HVAC air diffusers, acoustic panels for noise control, decorative architecture, and filter media or support in water filtration. It is often preferred for applications requiring light and sound control.

Perforated Aluminum

For outdoor applications, perforated aluminum is an excellent option. This is primarily due to aluminum’s ability to withstand the corrosion caused by natural elements. It can be exposed to rain and chemicals without sacrificing aesthetics or structural integrity. Similarly, perforated aluminum is an excellent option for applications that involve extreme cold, as the material gets stronger at below-freezing temperatures — although it should be noted that extremely high temperatures above 400 degrees Fahrenheit can result in the material losing some of its strength. Another advantage of perforated aluminum is that it is lightweight compared to other metals, including steel and copper, making it easier to install with fewer attachment points.

Perforated Steel

Perforated steel is more suited for indoor applications due to its susceptibility to corrosion, though coating with a material such as Tnemec can enhance its resistance. One of steel's key benefits is its strength and ability to withstand extreme hot and cold temperatures. It is a malleable material, although not to the extent of aluminum. In terms of large-scale projects that require perforated materials, steel is an excellent and economical option.

Perforated Stainless Steel

Stainless steel is one of the most popular options for perforated metals because it combines strength with high corrosion resistance. Perforated stainless steel is made with a minimum of 10 percent chromium, giving it corrosion-resistant qualities throughout its surface. It also has the unique quality of withstanding nicks and abrasions because its chromium oxide film will reform when in contact with oxygen. Depending on the type of stainless steel you choose for your project, it can resist various chemicals and liquids, such as salt water, making it ideal for applications in coastal regions. Stainless steel is used for indoor and outdoor decorative applications because of its consistently attractive appearance.

Perforated Copper

In terms of quality, copper is one of the best metals for practical and decorative applications. Compared with steel and other metals, copper is softer and more malleable, although its strength can be increased when combined with other materials. Copper is widely valued for its longevity and corrosion resistance. Though copper does oxidize and rust, the rust stabilizes after turning brown and eventually green. Some metals (such as zinc) added to copper to enhance its strength can diminish its corrosion resistance, so it is essential to know the application to find the right balance. For larger projects, perforated copper tends to be more expensive than other materials. Contact one of our staff to learn more about the best perforated materials.
