Stringer, tread, and riser are all components of which system?

Stringers, treads, and risers are integral components of a stair system. Stringers are the structural support that runs alongside the steps, holding them in place and allowing for the overall stability of the stairway. Treads refer to the horizontal parts of the steps where people place their feet when ascending or descending, while risers are the vertical components that connect each tread and define the height of the stair step. Together, these components create a safe and functional means for navigating between different levels of a building, which is the primary purpose of a stair system. Understanding the roles of these components is essential for recognizing how stair systems are constructed and function within the framework of a building.
