A staircase grille, also known as a stair railing or balustrade, is a safety barrier installed along the edge of a staircase to provide support and prevent falls. Staircase grilles come in a variety of materials, such as wood, metal, glass, or a combination of materials, and can be designed in many different styles to match the aesthetic of a building. The grille typically consists of vertical posts, called balusters, that support a handrail, which runs along the top of the balusters. Some staircase grilles also have additional features, such as a mid-rail for added safety, decorative elements, or glass panels for improved visibility. The purpose of a staircase grille is to ensure the safety of people using the stairs and to provide a barrier to prevent falls or accidents. Staircase grilles must meet building codes and safety regulations to ensure their proper functioning and durability.
