What Is Staircase?

A staircase is a set of steps that lead from one floor to another. It is provided to allow the means of ascending and descending between the various floors of the building. The room or enclosure of the building, in which the staircase is located, is known as a staircase. The opening or space occupied by the stairs is known as the staircase. In a domestic building, the stairs must be centrally located to facilitate access to all rooms. In public buildings, the stairs must be located close to the entrance.

Stairs can be built with wood, bricks, stone, steel or reinforced concrete. Stairs provide access and communication between floors of multi-story buildings and are a pathway through which fire can spread from floor to floor. Therefore, the staircase must be surrounded by walls, floors, roof, and fire-resistant doors. It is desirable that the wall and ceiling coverings are non-combustible and with the low flame spread. Another important aspect in the design of stairs is the aspect of strength.

They must be of satisfactory size and shape to allow them to be easily grasped by the hand.
