The spiral staircase

Features of the spiral staircase

The spiral staircase is one of the solutions that is always in vogue for organizing space, and indeed in relation to the tendency towards increasingly rationalized space, spiral staircase, updating its classic features, is used in many contemporary-style apartments.

It is, in fact, a type of vertical connection that does not require much space: arising on itself does not need a considerable overall dimensions given by the treads and risers, but simply of a width such as to allow the passage, in comfort, of one or more person.

The size of the slope is variable, then, according to your needs: we start from a minimum of 100 cm up to a larger size if you have more space and you want to allow the passage contemporary and easy to more people you can get so up to 150-200 cm.

If the house allows it, the ladder can reach a considerable size: the choice of the winding structure in this case is not dictated by reasons of space, but of simple taste.

Depending on the breadth of the staircase we make the hole that will allow the connection between the two floors: the diameter of the same will be given by the size of the slopes plus the necessary space to develop themselves and to implementation including all structural elements and accessories, such as, for example, the railing.

It must have a minimum height of 100 cm, so as to ensure the safety of users and it can be realized in metallic materials, profiles, tubular or fabrics, glass or plastic materials, with wooden elements, the staircase can have a structure in reinforced concrete fully closed or partially open which makes it self-supporting and independent from the package that hosts it.

To be safe and comfortable, it must have steps with a width of not less than 23 cm and not higher then 19 cm.
