Stair construction and layout

Stair is a type of vertical transportation in a building which consist of a series of steps in a flight of stairs that enable the vertical movement of people and materials from one floor to another. A staircase consists of steps that comprises of riser & tread, handrail, baluster, stair stringers, newel post and waist slab. The construction of staircase with all the components is termed as stair construction. A staircase is an enclosure that contains the entire stairway. The materials used for the construction of stairs are bricks, reinforced cement concrete, stone, lumber, steel and a combination of these materials.
