Delivery can take between 5 and 7 weeks from order.  The standard galvanised model is 5-6 weeks whist the powder coated options are more like 7 weeks.

As this is a custom made product we are not able to accept cancelations.

Once the staircase arrives in the UK, the haulage company will call you directly to arrange a suitable day for delivery.  The delivery is ‘kerbside’ although most vehicles will have a tail-lift and pump truck so can wheel the staircase to a suitable position across even ground. A signature will be required to accept the goods are in good condition.  The delivery company generally delivers between 8am and 5pm during the week.

Frequently asked Questions

This spiral staircase is made to order and is produced in Italy.  Delivery period do fluctuate during the year but are generally set at between 5-7 weeks from order.

The diameter you require will depend on a number of elements.  The application, the opening you have / can have within the floor and building regulations.  If you have building control involved in your project, please check what diameter they require.  Generally speaking, smaller diameters for lower use and larger diameter for more frequent use.

Normally a day for two people is enough to install the staircase.  This of course depends on the competency of the individuals.   Many clients opt to employ a builder/ joiner to install but they can be fitted by an experienced DIYer.

The entry and exit points are a crucial element to any spiral staircase.  This varies a little depending on the diameter and the number of risers you have.  Please see the relationship between the top tread and tread 1 on the downloadable file under the ‘ROTATION’ tab on the above table.  Or just click here.
