Spiral staircase COLUMBIA

EXCLUSIVE PREMIUM SPIRAL STAIRCASE

Our COLUMBIA is part of the premium range of DOLLE spiral staircase range. With high-quality components and a unique design, the staircase has 13 treads which can be adjustable from 20,5 to 22,5 cm to a maximum landing height of 292,5 cm. The treads, handrail and square landing platform are presented in solid oak with finishing oil Sioux White which altogether give a well-designed and modern staircase. The balusters give the staircase an elegant look with a grey lacquered banister.

You have a choice of two widths, this is the actual diameter of the spiral staircase, you can have 120cm or 140cm. The landing platform can be installed directly onto the ceiling area and it’s also possible to adapt the platform to suit round ceiling openings.

MEASURE YOUR FLOOR-TO-FLOOR HEIGHT

The DOLLE COLUMBIA STAIRCASE can reach a maximum floor to floor height of 292cm but can be installed at lower heights in two ways, either using the spacer rings we supply to achieve a perfect height or simply remove treads. The lowest height can be 244cm. The spacer rings are used to fit between the treads so you can land the staircase exactly to your specification. For the staircase to be comfortable to climb you will need to have an opening of 130cm round or square for a 120cm staircase or 150cm round or square for a 140cm staircase.

SAFETY & QUALITY

You can add a matching landing banister to match your COLUMBIA staircase. Just measure the area you are looking to banister? we can quote you to your actual specification, just contact us with details of your project.

TOP TIPS

The pitch height can be adjusted with spacer rings from 20.4 to 22.5 cm depending on floor height. We advise you use as little spacers as possible as this will mean narrow gap between the treads, this will make your staircase more comfortable to climb.
