Handrails for Stairs, Ramps, Walls & Balustrades

A handrail provides support and guidance when using stairs or ramps, while a balustrade is a protective barrier designed to help prevent falls. In many applications, the top rail of a balustrade can also function as a handrail, but each element has its own Building Code requirements.

The New Zealand Building Code classifies stairways according to how they are used. - Private stairways serve a single household. - Common stairways are used by the public or multiple occupants. - Accessible stairways form part of an accessible route and are designed for use by people with disabilities. Each classification has different handrail and accessibility requirements, so it's important to identify the stairway type early in the design process.

Yes. In many stairway applications, the top rail of a balustrade also functions as the handrail. However, the handrail must still meet the relevant graspability, height and accessibility requirements in addition to the balustrade meeting barrier and structural requirements.

Handrail requirements depend on the type, width and intended use of the stairway or ramp. Accessible stairways generally require handrails on both sides, while private and common stairways have different requirements under the New Zealand Building Code.

The appropriate handrail profile depends on the application and Building Code requirements. Accessible stairways have more stringent graspability requirements, while private and common stairways have different acceptable profile options.
