Model 76 Spiral Staircase

Our model 76 spiral stair is the most modern and stylish spiral we offer.  It’s transparent treads and sleek stainless balustrade design create a very open and light stair.  Many of our staircases are designed in a way that they become features within a dwelling but none more so than the model 76.  It has the ultimate ‘wow’ factor quality.  This model is suitable for all domestic applications.

It is a custom made spiral so each model created is unique, designed to the particular floor to floor height , diameter and rotation to suit the property.  Clients can choose from glass or acrylic treads and several options of balustrade design around the perimeter.

Being a custom made flight, each spiral is drawn carefully at the outset to ensure the correct entry and exit points are plotted.   With all spirals it is important that the position of the first and last step work in the setting and with the general  traffic flow of the building.  The characteristics of each property is unique so a spiral has to be designed accordingly.   From drawing approval, the model 76 spiral takes around 9-10 weeks to produce.

Each spiral stair comes complete with a top platform which is set level with the upper floor.  Matching landing balustrade is often supplied to protect the opening in the floor which is  designed to the precise length or curve required.

The model 76 spiral stair is formed by a series of interlocking barrels and treads which slot over the centre column.  These transparent treads cantilever directly out from the centre column creating a very light and open feel.

Balustrade Infill Options

To protect the side of the staircase a balustrade infill is required and there are several options to choose from which can dramatically enhance the appearance.  Please be aware that horizontal bars are often not permitted in the UK as they are deemed climbable.

How It Works

The system is clamped and bolted together.

Once the column centred & bolted down and the position of tread one is marked, the spiral is built up using a large threaded rod supplied in sections.  This runs up the middle of the cylindrical barrels and treads and receives a nut every 3-4 risers clamping together the treads/barrels already in place.  Another rod is fixed to the existing and the process continues  to the top of the spiral when the large platform is manoeuvred into position sitting flush with the finished floor.   The platform receives it’s own washer and nut to tighten down.

During this process the outer side of the treads need to be lined up with the correct overlap and the small tread to tread newels or spindles which lock this position need to be fitted.  The treads will also need to be propped with timber batons to ensure it doesn’t tip over.  Silicon washers are provided to prevent metal touching the glass.
