helical stair = spiral stair

The width and length of every landing should be at least as great as the smallest width of the flight. (minimum 1 m)

going = tread

Rise maximum 220mm. RISE = 150mm- 220mm.

H = 150mm-220mm

GOING minimum 220mm. GOING = 220mm- 300mm.

Private: intended to be used for only one dwelling.

Institutional and assembly: Serving a place where many people gather.

Institutional and assembly: Serving a place where many people gather.

Minimum headroom= 2m.

Maximum rise = 180mm. Minimum going 280.(If the area of a floor of the building is less than 100m2, the going may be reduced to 250mm.)

the maximum pitch for private stair is 42°.

The maximum pitch for gangways for seated spectators is 35°.

A stair in a public building which is wider than 1800mm should be divided into flights which are not wider than 1800mm.

The number of risers in a flight should be limited to 16 if a stair serves an area used as a shop or for assembly purposes.

at least 400mm.

at least 400mm.

In all buildings hadrail height should be between 900mm and 1000mm measured to the top of the handrail from the pitch line or floor.

Flights and landings shoul be guarded at the sides (in dewellings) when there is a drop of more than 600mm.

Single family dwellings:1. Stairs, landings, ramps, edges of internal floors. H= 900mm. 2. External balconies and edges of roof. H= 1100mm.

Flights and landings should be guarded at the sides to a height of 900mm. The construction should be that children will not readily be able to climb the guarding and a 100mm ball cannot pass through any openings in the guarding.

The normal relationship between the dimensions of the rise and going is that twice the rise plus the going (2R+G) should be between 550mm and 700mm.

2R+G = 550mm -700mm

Flights and landings should be guarded at the sides to a height of 900mm. The construction should be that children will not readily be able to climb the guarding and a 100mm ball cannot pass through any openings in the guarding.

For dwellings, for external tapered stairs that are part of the buildings, the going should be a minimum of 280mm.

minimum width of 900mm. Landings should be at least the width and length of the minimum width of the fight. For buildings other than dwellings, each landing should have an unobstructed length of at least 1,200m.
