Spiral staircases –
GI-RO spiral staircases meet the highest manufacturing and safety standards. They are flexible, cost-effective and architecturally valuable, suitable for use in both the private and industrial sectors. A key feature of a spiral staircase is the unmistakable curved arrangement of steps around a supporting column.
Our spiral staircases are often used as escape and fire protection staircases, for access to work and storage platforms and as external staircases to gardens and flats.
Many advantages combined!
- Very sturdy
- Weather resistance
- Versatile applications
- Architectural value
Our range of staircases offers many options to choose from
The name of our smart staircase solutions says it all. Our VARIO staircases offer high flexibility and variability. You can select from a wide variety of heights and diameters, as well as railing and step designs.
In contrast, our ECO type staircases are perfectly suited for one-storey to two-storey staircases in the private or industrial sectors.
GI-RO VARIO spiral staircase
Flexible solutions are our strength. The VARIO type spiral staircase is an enormously flexible solution with variable construction height and diameter. Whether in the industrial or private sector, this staircase in a hot-dip galvanised design can be used in many different ways, e.g., for multi-storey buildings as escape stairs. And because safety is a fundamental element in all our products, the VARIO type spiral staircase is not only characterised by the highest quality, but also offers the option of a protective cage to prevent unauthorised entry.
VARIO construction method:
With this flexible construction method, the landings and steps are first arranged around the stand pipe using pipe sleeves. They are then fixed by applying the specific railing consisting of a revolving balustrade made of horizontal round bars, or by vertical rods. The railing height varies according to regulations as follows: 1000 mm for overall staircase heights up to 12 m and 1100 mm for heights in excess of 12 m.
Technical features:
- Galvanised according to DIN EN ISO 1461
- Optional protective cage
- Kick plate on steps and landings
- Diameter max. 3000 mm
- Load 3.0 or 5.0 kN/m2
- Designed for an individual load of up to 2.0 kN (DIN EN 1991)
GI-RO ECO spiral staircase
Our ECO-type spiral staircase system is particularly well suited for constructing one-storey to two-storey staircases – both in the industrial and the private sector. With diameters of 1600, 1800 as well as 2000 mm, we adapt the stair type to suit your individual needs.
The ECO construction method:
The clever design of our ECO staircase system enables safe installation. The steps and landings are positioned directly against the stand pipe and bolted to it. The railing is then attached to the steps.
Technical features:
- Modular system
- Galvanised according to DIN EN ISO 1461
- One-storey to two-storey (height max. 4000 mm)
- Diameter 1600, 1800 or 2000 mm
