Stair nosing, types, dimensions, and benefits

Stair nosing refers to the edge of a stair tread that protrudes slightly over the riser. The purpose of stair nosing is to improve safety by providing additional traction and visibility on each step. 

The nosing also helps to prevent wear and tear on the front edge of the stair tread.

Purpose of stair nosing

1. Prevents slips and falls

The nosing provides an extra bit of material that protrudes over the edge of the stair tread, which can help prevent slips and falls by providing additional traction and stability for the foot.

2. Increases visibility

The contrast between the nosing and the tread helps to increase visibility, making it easier to see each step and avoid accidents.

3. Protects the edge of the stair tread

The nosing also helps to protect the front edge of the stair tread from wear and tear caused by foot traffic, which can help extend the life of the stairs.

Stair Nosing regulation

The National Building Code of India 2016 states that to reduce the risk of people stumbling on stairs, it is not recommended to have projecting nosing or open stairs. This means that stairs should be designed in a way that ensures that there are no protruding edges or open gaps that could cause someone to trip or fall. 

By following these guidelines, builders, and architects can ensure that the stairs are safe and minimize the risk of accidents or injuries.
