Strings – The inclined boards in which the treads and risers are enclosed.

Tread – The top or horizontal surface of a step.

Riser – The board that forms the face of the step. The maximum individual rise for domestic flights is 220mm.

Newel Cap – The ornamental top of the newel post. Often carved shaped or turned.

Landing – A resting place, or wide step anywhere within the staircase or top of a flight of stairs. Landings are often used to change the direction of a stair.

Handrail – A protective rail designed to prevent people or objects from falling into an open stairwell. A moulded rail following the pitch, or rake of the staircase – which also forms the top/upper edge of the balustrading.

Baluster – The vertical member, plain or decorative, that acts as the infill between the handrail and Channel (or tread if cut string).
