Perforated Materials - Applications of Perforated Materials

Perforated materials are used in a number of different applications for a variety of reasons. Used mostly as screens, filters, shields, and guards. Perforated materials can control the passage of air, liquid, light, solids, heat, electromagnetic waves, and sound waves.

With these abilities, perforated materials are often found in OEM applications such as clothes washer and dryer drums, speaker covers, automotive grills and exhaust components, airplane engine silencers, grain dryers, microwave ovens, computer cabinets, and countless others. In addition to OEM applications, perforated materials are also used for their aesthetics in architectural and design applications such as facades, fixtures, and privacy panels. As seen below, there are a variety of industries which use perforated materials for their various functions.

Knowing how perforated materials are typically used in industrial, architectural, and design applications may help you determine whether or not you have a use for it. Assuming there is a use for perforated, the issue then becomes which pattern to use. While this may be as simple as choosing one that looks a certain way, it can be critical for those applications where the perforated material has to perform a certain way (i.e. attenuate a sound frequency, provide a level of electromagnetic shielding, etc.). Many patterns are available using holes which are round, square, slot, hexagon, diamond or decorative in nature. For the consumer, some of the available patterns and styles may come with test results from independent laboratories relating to desired properties.
