A complete staircase is made of several interconnected parts, which can be broadly categorized into the structural components that form the steps and the balustrade system for safety.
The step system
These parts form the path you walk on, connecting one floor to the next.
- Tread: The flat, horizontal surface of each step that you place your foot on.
- Riser: The vertical section between one tread and the next.
- Nosing: The front edge of the tread that slightly overhangs the riser below it. This provides extra footing.
- Winder: A special, tapered tread used to change the direction of a staircase without needing a flat landing.
The safety rail system (balustrade)
- Handrail: The top rail that you hold onto for support when using the stairs. It can be mounted on posts or directly to a wall.
- Baluster: The smaller, vertical posts that support the handrail. Also known as spindles, they can be made of wood, or metal.
- Newel Post: The larger, sturdy post located at the beginning, end, or key turns of a balustrade to anchor and support the handrail.
- Newel Cap: A decorative piece that sits on top of a newel post for a finished look.
- Base Rail: A horizontal rail that runs along the bottom of the balusters, typically on top of the stringer.
The structure and framework
These components form the skeleton of the staircase, providing support and stability.
- Stringer: The inclined board that runs along each side of the staircase and holds the treads and risers in place. On some staircases, stringers can be exposed, while others hide the steps.
- Landing: A flat platform between flights of stairs or at the top or bottom of a staircase. Landings provide a place to rest and allow stairs to change direction.
