Parts Of A staircase


The handrail, also known as a bannister, is a protection bar that runs above the stairwell. A stairwell might have handrails on both sides or only one. Handrails are protection bars that run between the newel posts and on the balusters. 

A handrail serves a variety of functions, but the main function is providing a protective barrier for fall prevention.

It is a firm place to hold and support, particularly for the elderly and children while climbing or descending. And most importantly handrails enhances the aesthetics of the staircase.

The most popular materials utilized are cast iron, wood, copper, stainless steel, and aluminium.


Handrails are held in place by balusters, also known as guards or spindles. It is the vertical posts that connect the handrail to the steps /treads. They protect the handrails from damage and improve their integrity.

The balustrade is made up of several regularly spaced balusters and ornamental handrails. Marble,  glass, acrylic, wood, aluminium, cast iron, and stainless steel are common materials.


A staircase landing is a section of the floor located at the top or bottom of a staircase. Landings between flights of stairs make it easier to change the direction of the staircase.

The common types of landings that are used are half spaced landing and quarter spaced landings. A half-space landing extends across the entire staircase. A quarter-space landing extends across half of the breadth.

A landing completes the following functions: it allows for corners on staircases, minimizes the chances of slipping, it improves the slope, and it makes the steps structurally sound.


When you step on a staircase, your feet are put on a flat horizontal surface called the tread. It is the upper horizontal part of the staircase where you place your foot when climbing it.

It is the most important component of a staircase, and without it, the whole purpose of the staircase would be lost. Treads can be created from a variety of materials, including acrylic, wood, steel, tile, Granite, Glass, treated wood etc


The step is made up of the tread and the riser. The riser is the vertical component that joins two treads together.

The tread and riser add up to create the step. Staircases without risers are referred to as open-tread steps, whereas those with risers are referred to as closed-tread stairs.

A nosing is an overhang to the tread that goes beyond the riser.

This improves the aesthetic of the staircase while also expanding the breadth of the tread, making it easier to use. Nosing also makes the steps


The framework made with a long piece of MS, Wood or steel member is essentially the backbone of Stairs. It is where the treads and risers are joined.

Depending upon the design of the staircase it can be found on the center, side or on either side of the steps to provide structural support for the staircase.

Rise & Run

The vertical distance between the first and last treads represents the overall ascent or the rise of the staircase. The run is the horizontal distance between the first and last risers is also known as the going of a flight.
