A balcony grille, also known as a balcony railing or balcony balustrade, is a barrier installed along the edge of a balcony or terrace to provide safety and support. Balcony grilles are typically made of metal, such as steel or aluminum, or materials like wood or glass, and come in a variety of designs and styles. They are designed to prevent people from falling off the balcony and to provide support for leaning or holding onto. Balcony grilles may also serve as a decorative element, enhancing the look of a building's exterior. Some balcony grilles come with additional features, such as privacy screens, windbreaks, or built-in lighting.
