Each material has its advantages.and disadvantages. The construction of a staircase requires durable, robust and high quality materials. Winders : Radiating steps narrower at one end that are used to change the direction of a stairs through 90° or 180° What are the best materials for your staircase? Wall String : String of a staircase fixed flush with a wall. It ensures the stability of the staircase.
The stringboard is used to support the loads of the stairs. Stair stringer : Located on the side opposite the wall, the stair stringer is a piece of wood or steel on which the steps, risers and bars of the ramp rest. Depending on how the staircase is connected to the structure, the beam can be hollow or solid. Spiral Stair Beam : Concrete central column of a prefabricated spiral staircase. The maximum individual rise for domestic flights is 220mm. Riser : Board that forms the face of the step. The individual rise is the vertical measurement from top of tread to top of tread. Rise: Rise of a flight is the vertical distance between the floors or landings connected by the flight. Rack or rack stringer: An inclined piece of wood with steps, on which one of the ends of the steps and risers rests. Pitch Line: Notional line connecting the nosings of all treads in a flight of stairs. Pitch: Angle between the pitch line and the horizontal. OAS: OAS refers to the width of the Staircase = Width Overall Strings.
Nosing: Edge of the tread projecting beyond the face of the riser and the face of a cut string. Newel Post: First element of the balustrade, fixed to the ground before the start of the stairs. Landing: Horizontal platform at the end or between two flights of stairs. Handrail: Upper part of the staircase that serves as a support for the hand. Half Landing: Flat area of flooring where a stairway makes a turn between main floors. The individual going of a step is measured from face of riser to face of riser and for domestic use should be a minimum of 220mm. Going: Going of a flight of stairs is the horizontal distance between the face of the first and last risers. Here are the main components that will help you better understand the structure of a staircase.īalusters/Spindle: Elements of various shapes (round or square section, wood, metal, steel, iron) located between the staircase stringer and the handrail.īalustrading : Collective name for the complete assembly of handrails, baserails, newels, spindles and caps.īullnose Step : Part that is usually at the bottom of the stairs with one or both ends of the step having a quarter circle design.Ĭorbel : Sealed bent metal piece for holding against a wall, a wall stringer or a dummy rack.Ĭlosed String : String with the face housed/trenched to accommodate treads and risers so their profile cannot be seen.Ĭontinuous Handrail : Using straight lengths of handrail connected to handrail fittings and ramps, the handrail flows over the tops of newel turnings creating a continuous run of handrail.Ĭurtail Step : Decorative shaped step at the bottom of the stairs usually accommodating the volute and volute newel turning of the Continuous Handrail System.Ĭut or Open String: a string with the upper edge cut away to the shape of the treads and risers so that their profile can be seen from the side.įlight (of stairs) : Set of straight steps between two landings of a staircase. A better knowledge of staircase components and parts will allow you to choose the right model and materials. By having quality components and materials on hand, your construction will be durable, robust and unique. The construction of a staircase is a colossal project that requires a significant investment.
