Stair Detail and Section Drawing Staircase Construction Layout

This stair detail and section drawing presents a detailed architectural layout illustrating the internal structure and construction components of a staircase. The drawing shows the vertical section of the staircase, including tread, riser, landing, and structural support elements that define the stair construction system. Stair section drawings are used in architectural and structural documentation to clearly represent how stair components are arranged and connected within a building structure. The tread represents the horizontal surface where a person steps, while the riser forms the vertical face between two steps, both of which are essential components in staircase design.
