How many treads do I need for my spiral stairs?

How to calculate the number of treads

For your finished floor to floor height in mm:

UK Regulations EU Regulations Number of Treads
2100-2200mm 2100-2300mm 10 treads/risers
2310-2420mm 2310-2530mm 11 treads/risers
2520-2640mm 2520-2760mm 12 treads/risers
2730-2860mm 2730-2990mm 13 treads/risers
2940-3080mm 2940-3220mm 14 treads/risers
3150-3300mm 3150-3450mm 15 treads/risers
3360-3520mm 3360-3680mm 16 treads/risers

This table shows the individual tread rise range which can be installed for this staircase, from the minimum (210mm) to the maximum (230mm).

This staircase is carefully designed and manufactured in Italy and is a certified product CE European Technical Approval – ETA. However, European staircase regulations differ from those in the UK, in particular about the maximum tread rise. Please note that UK regulations require a maximum tread rise of 220mm and the table above will show how many treads you would need for the UK or EU.

Just to explain how the individual tread rise is adjusted, each tread rise section comprises the centre column (part no. C20-300) with a rigid plastic shim (C20-295) set into each end of the column. This results in a tread rise of 210mm. To increase the tread rise, additional shims are added at either end of the column, which will increase the tread rise by 5mm for each one, as shown in the following diagrams.
