Details for stair nosings and anti-slip depend on the finished tread, substrate and junction with the riser and landing. For nosings for timber stairs, allow for the final wood finish and check that the profile meets the tread edge without an abrupt change in level. Nosings by Paradise Timbers is a listed example; compare its stated dimensions with the stair detail before specifying.

Stair Nosings & Anti-slip

In Australia, stair nosings and anti-slip performance should be checked against the requirements for the building’s use. Consider the surface finish, visual contrast and fixing together, rather than relying on material alone: metal and wood profiles can behave differently underfoot. The Nosings by Paradise Timbers listing should be assessed using its product documentation, including any available slip-resistance information. Coordinate the detail with adjoining finishes and allow for more than the nominal tread depth when setting out.

What should a stair drawing show at the nosing?

Dimension the finished tread and riser, then show the profile, projection and junction with the floor finish. Include the fixing detail and substrate.

How can slip resistance be assessed?

Request test information for the specified surface finish and conditions of use. Compare it with the requirements that apply to the building and its use.

What should be checked for an external stair?

Confirm the manufacturer’s guidance for weather exposure, drainage and cleaning. Check that the fixing method suits the substrate and site conditions.
