Concrete Stair - Nosing Bars
Concrete Stair - Nosing Bars
(OP)
Folks,
What is the consensus on using Nosing bars in risers for concrete stairs?
We have an ongoing debate in the office that these nosing bars do more bad than good. One school of thought says that the nosing bars are there to provide T&S reinforcement for the risers.

Make sure it is non-slip nosing.

The (.) indicates the nosing bar. I am not talking about a nosing angle. It is a reinforcing bar provided below the nosing.

1. Difficult to place - why place when there is no benefit?
2. When concrete cracks, these bars cause more spalling of the nosing.

They are difficult to place, cause a 'hard' point at the edge of a stair; this stress riser can cause the concrete to spall off at the nosing... If not placed right, they're subject to chloride corrosion if deicing salt is used.

Thanks for the response. I am early in my career and haven't seen many stairs with problems and hence, the question about best practices.
Does anyone have a valid reason to use them at all? Or is it a unanimous N0-NO?
