Stair nosings: tread width, riser return and fixing
Specify a stair nosing using the tread coverage, riser return and installation method. A single width dimension does not describe its full cross-section.
Selection considerations
Survey existing steps or coordinate new steps with the finish build-up. Compare surface-mounted and recessed options before ordering. Include adhesive beds, inserts or concealed fixing where the selected system requires them.
Review the leading edge for a consistent fit across the stair flight. Ask for evidence supporting any specified slip or wear performance, including the relevant surface condition and test method. A textured picture is not a test result. Retain the approved nosing and insert references so repairs use the intended geometry and finish.
Before you specify or order
- Measure tread and riser geometry
- Confirm surface or recessed installation
- Request relevant performance evidence

Common question
Does a grooved surface prove slip resistance?
No. Use documented performance under the conditions relevant to the project.
