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).
