Stair nosings are placed on the edges of stairs to prevent accidents from occurring. Firstly, a person using the stairs can correctly judge the end of the stairs, hence reducing the chances of missed steps. Secondly, a stair nosing can also help increase friction of the stairway. This prevents slipping which may lead to serious injuries on the stairs. Thirdly, it also improves the aesthetic aspect of stairs itself, which may vary according to the design adopted.
