A riser is a vertical or inclined component used in various engineering and construction applications to convey fluids, gases, or other materials from one level to another. In plumbing, risers refer to pipes that transport water or sewage upward within a building, connecting different floors to the main supply or drainage system. In electrical systems, a riser can refer to vertical conduits that house electrical cables running between floors. In the context of structural design, risers can also denote the vertical segments of stairs, contributing to the overall design and functionality of a staircase. Made from materials such as PVC, metal, or concrete, risers are essential for maintaining efficient flow, structural integrity, and safety in various systems, ensuring reliable performance in residential, commercial, and industrial environments.
