An open area grille, also known as a perforated grille, is a type of metal grille that consists of a series of interconnected holes arranged in a pattern. It is commonly used in building and architectural design as a decorative element or for functional purposes, such as ventilation or air circulation. Open area grilles can be made from a variety of materials, including aluminum, steel, and stainless steel, and come in a range of shapes, sizes, and patterns. They can be used for both indoor and outdoor applications, such as on walls, ceilings, or floors, or for fencing, screen walls, and sunshades. Open area grilles are versatile and can be easily customized to suit the specific design requirements of a project.
