TYPE ECO (1600/1800/2000)

Spiral Staircase Typ Eco

Our spiral staircase system type ECO is especially suitable for single or dual-floor staircases for the industrial as well as the private sector. Different diameters (1600mm / 1800mm / 2000mm) allow this type of staircase to be customized to suit individual requirements.

Construction

The smart construction of the staircase system ensures safe installation. Due to the fact that the treads and landings are mounted on the central column, the central column can be reliably attached to the plinth, another platform or the building itself. The respective treads and the balustrade with the handrail are mounted in the second step.

TYPE VARIO

Spiral Staircase  Typ Vario

One of our many strengths are flexible solutions. The spiral staircase Type VARIO convinces with its variable design height and its variable diameter. Whether it’s the industrial or the private sector, this hot-galvanized type of staircase can be used in multi-floor buildings in different ways. At GI-RO, security always comes first: This spiral staircase does not only stand out due to its superior quality, but it also offers the possibility to install a protective cage against unauthorized access.

Construction

With this flexible solution, the landings and steps are firstly slit over the central column using tubular sleeves. Afterwards, they are mounted above the balustrade using midrails or the vertical balusters. The height of the balustrades varies according to regulations. For an overall height under 12m, 1000mm are required – an overall height exceeding 12m requires 1100m.

      TYPE GI-RO EXPRESS

      Spiral Staircase Typ GI-RO Express

      The hot-galvanized spiral staircases of type GI-RO Express are delivered within ten business days. In this context, every staircase is customized in regards to pitch and helical winding. Offering diameters of 1600, 1800 and 2000mm, our modular system is very attractive for an overall staircase height under 4000mm and a rectangular, standardized exit plinth.

      Construction

      Designed for a load of 3.0 kN/m2 and 2kN point load, the treads and landings of the staircase type GI-RO Express are mounted onto the central column. During the installation, the central pole is attached to the plinth and to the building. Finally, the steps are mounted together with the balustrade elements and the handrail.

        LANDINGS

        We manufacture landings in preferred or customized dimensions. The detailed planning, including static calculations for pillars and attachments, is carried out after selecting the staircase and the landing. We manufacture landings in a variety of versions to meet the customers’ requirements. The example graphics below show the landings for clockwise, as well as for anti-clockwise turning staircases. With spiral staircases turning clockwise, the central column is located to the right of the steps and vice versa with spiral staircases turning anti-clockwise.

        PLANNING AID

        Once you have decided on one of our staircases, it is necessary to determine the details. Diameter, pitch and the number of steps. The following graphics show the usual divisions to help you plan different diameters: This way, the position of the first step (entry) and the last step (landing) can be determined.

        Step measurement

        The rule to calculate the step measurement as defined per quality standard:
        (2 x rise + tread width = 600 – 660mm).

        15 steps / spiral
        diameter: 1500 – 1800mm
        effective tread width: 220 – 265mm
        15 steps / spiral
        16 steps / spiral
        diameter: 1700 – 2000mm
        effective tread width: 235 – 275mm
        16 steps / spiral
        18 steps / spiral
        diameter: 1900 – 2200mm
        effective tread width: 235 – 275mm
        18 steps / spiral
        20 steps / spiral
        diameter: 2100 – 2400mm
        effective tread width: 230 – 265mm
        20 steps / spiral
        22 steps / spiral
        diameter: 2300 – 2700mm
        effective tread width: 230 – 270mm
        22 steps / spiral
        24 steps / spiral
        diameter: 2600 – 3000mm
        effective tread width: 235 – 275mm
        24 steps / spiral

        Please bear in mind:

        In order to help you take into account all the mandatory requirements in the planning process, we have compiled the main information of DIN 18065 (German standard for stairs, balustrades and handrails) and extracts of the German Landesbauordnung (state construction ordinance) and the German accident prevention regulation in one document for quick reference. In case further regulations apply, please inform us of such circumstances. Unless informed otherwise, we assume that only those regulations laid down in DIN 18065 are applicable.
