STRUCTURE
Central upright composed of cylindrical painted metal spacers with interposed plastic rings for adjusting the lifts.
La struttura è composta dai gradini e dai distanziatori interposti tra i tubolari e bloccati su una flangia in materiale plastico con all’interno un tirante con bloccaggio a compressione.
Material
FE360 steel
Materiale plasico: nylon
Surface treatment
Wood: finish with double layer of transparent natural color paint.
Steel: painted with epoxy polyesterity powders.
STEPS
In massive beech wood made up of 40 mm thick slats glued together
Material
Massif beef format formed by 40 mm thick slats jutted with vinyl glue.
Surface treatment
Treatment with double layer of polyurethane transparent paint.
RAILING
With fixing on the step
The choice of the railing affects the ingrustment and the convenience of the spiral staircase.
La funzionalità della scala a chiocciola dipende prevalentemente dal fissaggio della ringhiera. Possiamo avere il fissaggio sopra il gradino, di solito con tubo passante riducendo però la superficie di appoggio del gradino e il passaggio utile.
In alternativa la ringhiera è possibile fissarla lateralmente aumentando così la dimensione complessiva della scala, e lasciando più spazio libero a chi la percorre. Questa soluzione è quindi preferibile in contesti in cui si vuole privilegiare la comodità.
PARAPET
Formed by vertical uprights of the circular section fixed to the step and the handrail by means of plastic joints.

NOTES
Precautions for use
Surface treatments can change the coloring and tone if exposed to direct light. Do not expose the staircase to heat sources over 45 °.
Maintenance
To laying performed, check the complete tightening of the whole viper which will be chewed after about 12 months.
Cleaning
Once the laying is finished cleaning the parts in view of the staircase. Ordinary cleaning must be performed with a damp cloth without abrasive products or solvents.

Width and diameter of the spiral stairs
The choice of the width of the spiral stairs is often tied by the size of the compartment and the hole available. It is a good rule to choose a diameter that is a few cm lower than that of the hole in order to have the possibility to make the necessary corrections.
The diameter of the spiral stairs cannot be smaller than a certain extent, both for legislative reasons and for ergonomic and practical reasons (spiral stairs with too small diameters would not allow the passage of a person).
The minimum dimensions for spiral staircases are defined in the UNI 10804 regulation of 1999 where the guidelines for correct design are defined.
Round spiral staircases should not have a diameter of less than 110/120 cm, while square ones can reach a minimum of 100 cm.
As regards the maximum diameter, however, the only limit is the design one.
Normally the dimensions of spiral staircases vary from a minimum diameter of 100 cm to a maximum of 200 cm with a progression of 10 cm by 10 cm in order to cover all possible hole dimensions. In particular cases or for larger diameters, tailor-made projects can be created.
HEIGHT AND NUMBER OF STEPS OF THE SPIRAL STAIRCASE
The number of steps on spiral staircases depends on the total height that needs to be reached.
To get an idea of how many steps will be necessary, it is necessary to carry out a measurement that also considers the thickness of the floor and the arrival floor, which must be calculated from the starting floor to the arrival floor.
It is however possible to design a staircase with a greater or lesser number of steps.
It all depends on the riser between the steps you choose. A low riser allows you to have a staircase that is very comfortable to walk on, but with a high number of steps. Conversely, a greater rise reduces the number of them, and therefore the bulk, to the detriment of the ease of climbing.
Furthermore, when choosing the number of steps, the position of the first step must also be taken into account.
Increasing or decreasing the total number of steps also determines a movement of the starting step, which is why it is always a good idea to check that it is not in correspondence with obstacles, walls, windows or anything else.
The spiral staircase C20 KIT 1688-1848 H 1100 mm on the previous page has been calculated with a number of steps equal to 8; this does not prevent you from having a different number of steps by changing the rises from step to step.

ROUND OR SQUARE SPIRAL STAIRS
The main difference, which also gives rise to different performances, is in the shape of the step, rounded for the round and pointed for the square.
Generally, square stairs, with the same diameter, allow you to make the most of the corner spaces between the walls, offering greater useful space.
Thanks to a higher support surface for the step, these stairs are therefore wider and more comfortable to walk on. The round-shaped staircase, on the other hand, is aesthetically more graceful than the lines offered by square-shaped stairs.
