Perforated metal, also known as perforated sheet, perforated plate, or perforated screen, is sheet metal that has been manually or mechanically stamped or punched using CNC technology or in some cases laser cutting to create different holes sizes, shapes and patterns. Materials used to manufacture perforated metal sheets include stainless steel, cold rolled steel, galvanized steel, brass, aluminum, tinplate, copper, Monel, Inconel, titanium, plastic, and more.
The many uses for perforated plates include:
- Building design, architecture, and decorative artwork
- Machinery ventilation that allows heat to escape while protecting machine interiors
- Increased airflow in a building
- Industrial filtration: aluminum and stainless steel perforated plates are excellent for filtering food products and keeping mechanical equipment clean
- Acoustical applications, including controlling sound outside and reducing echoes indoors
- Balancing natural light and shade, allowing the ideal amount of light into the building
- Providing privacy by limiting visibility, while allowing in light, sound and airflow
- Improving building appearance by giving the façade a texture that cannot be achieved with other materials
