A mono-stringer staircase is a type of staircase design characterized by a single central support beam or stringer that runs along the length of the staircase, supporting the treads and risers. This design creates a sleek and modern look, often favored for contemporary and minimalist interiors. Mono-stringer staircases can be made from various materials such as steel, wood, or concrete, offering durability and structural stability. They allow for open and airy spaces beneath the stairs, enhancing the sense of openness in a room. This design also offers flexibility in terms of customization, allowing for different tread materials, finishes, and railing styles.
