تعریف و معنای "staircase"

What is a "staircase"?

A staircase is a set of steps that connects two or more levels in a building, allowing people to move between floors. It typically consists of treads, which are the horizontal surfaces for stepping, and risers, which are the vertical components that connect the treads. Staircases can be straight, curved, or spiral, depending on the design of the space. They may also include features such as handrails or balusters for safety and support. Staircases can be made from various materials, including wood, metal, or concrete, and they serve both functional and aesthetic purposes in architectural design.
