Special anti-slip inserts can be provided to the nosing to bring an anti-slip environment. These recommendations vary in extreme areas like exterior stairs and very wet areas. The selection of proper nosing for the stair is a critical criterion in the stair design. Consider these recommendations as a safety concern for a staircase instead of taking it as an aesthetic feature alone. The guidelines while choosing nosing must be followed irrespective of how large or small the number of flights are.
