Handrail / Baluster
Balustrading is required to comply with the BCA and be stiff enough to withstand exerted pressure. Balustrade may have a handrail over. The Building Code of Australia Parts 3.9.1 and 3.9.2, Volume 2 and Australian Standard 1170.1 are written to ensure building that enables people to move safely between different levels of the building using stairs or ramps.
To prevent people from falling, a continuous balustrade or barrier must be provided alongside any stairway or ramp, any floor, corridor, hallway, balcony, verandah, mezzanine or path of access to a building if it is not bounded by a wall or any level more than 1 m above adjoining floor or finished ground level. It is important to note that the measurement of the height of the balustrade or barrier is from the finished floor surface. Finishes such as ceramic tiles and even carpet can make a significant difference to the finished floor height.
