A "Riser" is a term often used in construction and architecture to refer to the vertical part of a staircase. It is the section that connects one step to the next, providing the height needed for each step. Risers are essential for creating safe and comfortable stairways, as they determine the overall height and angle of the stairs. In a broader context, the term "Riser" can also refer to a type of pipe used in plumbing or heating systems. These pipes transport water or other fluids vertically through a building, ensuring that every floor has access to necessary resources. plumbing, staircase, architecture
