10mm steel plate; Max depth 450mm 10mm steel plate fitted to face of slab to spread load |
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. |

SITE SURVEY
PLANNING REQUIREMENTS

In order that we may progress to the manufacture of your staircase the following is required.
Measurements
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.
Drawings
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.
