Staircase Parts

Riser

The riser is a vertical part of the staircase. It sometimes connects two treads. In old designs or in building staircase riser connects 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. This is known as an open riser-style staircase.

Tread

The trend is a horizontal or flat part of a staircase, which fits between two extreme supports or railing. It acts as a walking surface while climbing. At every specific distance, it is fixed on the staircase.

Stair Nosing

Nosing is an intersection point or line between the riser and the tread.  

Cut String/Stringer

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.

  1. Western
  2. Eastern
  3. Mono

Newel Post

Newel posts are the vertical members at the extreme side of the stairs. It is strong and heavy in construction to support the handrail. Sometimes these newel posts are attached to the ground or floor directly. It is sometimes plain or decorative in shape.

Newel Cap

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.

Base Rail

The balusters are mounted on the base rail and supported on the stringer. It gives support to the newel posts.  

Landing
