Spiral Staircases

Space Saving Elegance With a Spiral Staircase

Spiral staircases are an attractive architectural feature. Due to their small footprint they are a practical choice when space is limited, or as an aesthetic preference for creating a striking interior or exterior feature. Both new and used spiral staircases for sale can be found on eBay.

The spindle and handrail will usually be metal or PVC. The treads and bannisters can be made from a variety of materials. Landing platforms are often included and usually match the treads.

Consideration should be given to the material in the location and an allowance made for possible expansion and contraction of organic materials.

• Cast Iron: Many of the cast iron spiral staircases listed will be antique cast iron decorative structures, either refurbished or requiring renovation. These are attractive sought-after pieces.
• Other metals: Stainless or mild steel are also used. These can also be combined with wood and project a more contemporary look.
• Solid wood: Wooden spiral staircases can be entirely created from wood. A masterpiece in joinery, these are a high-end option. Solid wood treads can also feature in metal-framed versions.
• Veneer: Some treads can be made from a more economical composite, such as MDF, but clad in attractive veneers. Veneer and solid wood options are suitable for interior use only.

New spiral staircases can be purchased either left-handed or right-handed. The direction refers to ascending the staircase.

To establish the size of the staircase, first, measure the ceiling opening, then subtract 10 cm. This will give you the correct diameter. Next measure the floor height. This is the finished floor to finished floor level, rather than up to the joist. New spiral staircases are manufactured in set widths, such as 1200 mm or 1400 mm. There is usually some adjustment in pitch and bannisters.

Building regulations will need to be adhered to for any staircase installation. You should check specific designs with your local building control department but a general guide is a minimum sphere of 100 mm and there must be no gaps greater than 99 mm anywhere on the staircase. The minimum width is 660 mm (26 inches), with each tread a minimum distance of 190 mm (7.5 inches) at 12 inches from the narrow edge.

A designer alternative are helical stairs. The main difference being that a spiral staircase has a central vertical spine, whereas helical, or curved, staircases do not and can follow any shape or direction desired.
