The Oak is normally factory finished with a varnished or oiled finish. If supplied oiled the oak will require reoiling every so often for the first couple of years – much like a kitchen work surface. Some customers choose to revied the oak unfinished so they can use the same finish they are using elsewhere in the property. If you are installing a secondary spiral staircase for access to loft space, office, playroom, mezzanine floor etc you should have no issue in fitting a more basic spiral staircase as this is deemed non habited temporary access

Balustrade and handrail: The type, quality, and design of these will affect your overall spiral staircase costs. One of the most common questions we get asked is “where does the spiral start and finish”. The rotation of a spiral staircase is determined by Many winemakers will say that great wine is really made in the vineyard. Their job is simple: do no harm and let the grapes work their wonder. But the winemaker’s role deserves more credit than just serving as a sort of chaperone for the grapes. Decisions are made almost daily along the wine processing continuum and it is the winemaker who navigates the journey that leads to greatness. The guidance on diameters are set out by a British Standard 5395 part 2. This document divides spiral staircases into 5 categories depending on their usage and sets ‘clear tread width’ requirements for all. This in turn dictates the overall diameter.

Spiral staircases are freestanding structures built around a central column, so they don’t rely on needing a wall for their positioning. A stylish focal point

Rise height: (S) difference between the treads must be between 18-21cm. Low rise e.g., 18 cm provides better comfort. These unusual and attractive trees, also called upright English oak trees, were first found growing wild in a forest in Germany. These types of columnar oaks were propagated by grafting.The spiral staircase was supplied with solid oak treads on a steel structure with a large steel band wrapping around the perimeter of the spiral. The platform was enlarged so that it formed a walkway upstairs and matching landing balustrade was supplied for this and the rest of the mezzanine level. The balustrade was constructed with horizontal stainless steel rails, topped with a stainless steel handrail. Being commercial, we included a handrail to the centre column and ensured the clear tread width was 800mm minimum. A monumental, completely free-standing, dark oak spiral staircase. The central newel of this very large spiral staircase consists of an entire solid oak tree trunk, which is made into a strong pole with a diameter of 30 cm. Because of this, the bullnose steps around it have remained firmly in place for 150 years without sagging. Although we do supply all oak spiral stairs it is more common that a client just selects oak trads and handrail. For example, our model 71 for example has stainless steel spindles and centre column and this combination with oak treads and handrail works very well. In addition to the material, here are the other factors that would affect your spiral staircase installation cost.

Landing banister: The height of our landing banister (balcony balustrade) must at least be 100 cm, and the height of our stair handrail is at least 90 cm. It is always possible to choose a railing for the stairs or repos with vertical balusters, where the distance is a maximum of 10 cm. In our assembly instructions and dimension sheets you will find measurements on stair railing and landing banisters. Ideal columnar oak tree growth conditions include a sunny location. Plant these oaks in direct sun on well-drained acidic or slightly alkaline soil. They are extremely adaptable and very tolerant of urban conditions. They also tolerate drought and aerosol salt. Caring for Columnar Oak Trees Throughout this ongoing winemaking activity, the possible application of oak arises almost any time. From fermentation to just weeks before bottling, this abundant resource with properties naturally created for winemaking is applied in all kinds of formats to perform one or more critical functions. Whether to build, enhance, support, sweeten, lengthen, lift, mask, improve, complement, round-out or add structure, oak is second only to grapes in the hierarchy of components that directly impact the winemaker’s final product. Headroom: There must be a head room above the stair of at least 2.2 meters (preferably more) – on every tread on the way up. See our dimension schemes on each staircase.

Thanks to their steeper incline, spiral staircases generally take up a lot less space than traditional staircases. More light in the room The oak round edge (stringer) that surrounds the steps consists of large, hand-worked, strong pieces of oak that show the extraordinary craftsmanship of the stair builders.
