Stair Tread - Nosing, Round

Scaled set of drawings of Round Nosing Stair Tread in diagram and side views
Description
Description

Round stair tread nosings feature a curved, rounded edge on the outer part of each stair tread, creating a smooth transition from the tread to the riser. This design enhances safety, as the rounded edge can help prevent tripping and lessen the impact in case of a stumble. Aesthetically, round nosings give a softer, fluid look to the staircase, smoothing out the typically sharp angles.

This design detail can be applied to a variety of staircase styles, from traditional to modern, contributing to an overall look of refinement and elegance. Therefore, round nosings balance functionality, safety, and design appeal.

Round Nosing Stair Treads are constructed with typical stair tread thicknesses between 1”-1.5” (2.5-3.8 cm) and allowable nosing overlaps of 1”-1.5” (2.5-3.8 cm). Round nosings can have a maximum radius of .5” (1.3 cm).

Stair treads have a minimum allowable depth of 11” (28 cm) with riser heights between 4”-7” (10-18 cm). Stair nosings can protrude between 1”-1.5” (2.5-3.8 cm) with a maximum riser angle of 30 degrees.

Stair treads and risers are fundamental components of a staircase. The tread is the horizontal part that you step on, while the riser is the vertical section between each tread. Together, they determine the comfort and safety of the staircase. The dimensions of treads and risers must be balanced.
