Helical staircases (curved with two stringers) in use are under stress to push outwards and therefore require :-
- A very strong fixing at landing floor, preferably a steel plate. (see drawing opposite)
- At the foot of the curved staircase a reinforced concrete base is always recommended, size and depth of this concrete base should be determined by a structural engineer.
- Depending on support available from adjacent bearing walls a support post at the curved section may be required.

When considering designer staircases attention
should be paid to the following;
|Cantilever Staricases||Alternative Method|
|Cantilever staircases can only be fitted to a level bearing wall.
A steel frame is fixed to the wall below the finished surface
Min wall thickness: 250mm
Max tread width: 1200mm
Max tread depth: 100mm
|Single “Z” shaped stringer fixed to face of wall|
Accurate measurements are only able to be taken once the well is completed with walls plastered and the ability to have an exact floor to floor height.
If we are asked to commence manufacture before this is possible then the onus and risk of the stair not fitting passes to the builder to ensure that the finished measurements are exactly as those agreed.
Once measurements are agreed drawings are raised and sent to the client for careful checking and by signing agree that all details are correct.
N.B. Manufacturing will only commence once signed drawings have been returned. All quoted delivery times are from when the signed drawings have been returned.
