UTOP stair nose description:

The purposes of nosing on stairs:

Other than being a necessary part of the structure of a staircase, does stair nosing serve any other purposes?

The main purpose of a nosing is to improve the safety of the staircase.

As it protrudes a little over the edge of the tread, it provides some extra space for users to place their feet.

The attention of installation of stair nosing:

The greatest stair tread nosing projection shall not exceed the smallest nosing projection by more than 3/8 inch (9.5 mm) between two stories, including the nosing at the level of

floors and landings.

A nosing is not required where the tread depth is a minimum of 11 inches (279 mm).
