A perforated plate is a flat sheet of material, often metal or plastic, that has a series of holes or openings punched through it. These holes can vary in size, shape, and spacing, allowing for different levels of airflow, light transmission, or liquid flow. Perforated plates are commonly used in applications such as filtration, sound absorption, and architectural design. In industrial settings, perforated plates are utilized in equipment like filters and screens to separate materials or control the flow of substances. They can also be found in furniture and building facades, where they serve both functional and aesthetic purposes.
