Stairs are a structure designed to bridge an extensive vertical distance between lower and higher levels by dividing into smaller vertical lengths. It is achieved as a diagonal series of horizontal platforms called steps. It enables passage to the other level by stepping from one to further steps in turn and drives it cozy in crossing large vertical distances. The staircases are available in rectangular, round, or any customized shapes, and their material is wood, metal, concrete, or more. Material selection depends on the space availability or type of application. Various individual parts of a staircase make it more customizable to use as per the house, building, industry, and more. We can give different shapes to each staircase part and make them attractive. In this article, we will see all those staircase parts and their functions.

Staircase Parts & their Functions
The riser is a vertical part of the staircase. It sometimes connects two treads. In old designs or in building staircase riser joins two treads.
Example- In the construction of a staircase with concrete. While in the modern staircase, the riser does not connect to the treads, or sometimes it is absent. It is known as an open riser-style staircase.
The trend is a horizontal or flat part of a staircase, which fits between two extreme supports or railings. It acts as a walking surface while climbing. At every specific distance, it is fixed on the staircase.
Nosing is an intersection point or line between the riser and the tread.
Stringers are the two extreme sides of the staircase, wall string (inner) and closed string (outer). It holds or gives support to the riser and tread.
All the loads get transferred to the stringers during walking through the stairs. So, it is necessary to have a strong structure of the stringer.
Types of the stringer.
The handrail is a supporting structure while walking up and down the staircase. People can hold the handrail while walking. It fixes on the extreme sides of the staircase.
The function of the guardrail is to protect a person to drop from the staircase. It fixes on the extreme side of the stringer of the staircase.
Balusters are vertical members fixed at a specific distance to support the guardrail and handrail. It increases the aesthetics of the staircase. The whole construction of the baluster is called a balustrade.
Newel posts are the vertical members at the extreme side of the stairs. It is robust and heavy in construction to support the handrail. Sometimes these newel posts are attached to the ground or floor directly. It is occasionally plain or decorative in shape.
The Newel cap is the top cap of the newel post. It can be square, spherical, or customized in shape. It improves the look of the post and makes it decorative.
The balusters are mounted on the base rail and supported on the stringer. It gives support to the newel posts.
Landing is flooring at the bottom and top of the staircase. It is a resting portion of the space to give access to the lifts and rooms. While taking turns at a specific angle (45 to 90 degrees), the landing portion is present.
It is an outer structure of the landing. It covers the open space of the balcony and ceiling.
