A spiral staircase is one of the oldest configurations of the steps. Its definite advantage is that it requires a minimum of space. The price of this design in comparison with the main counterparts is more affordable. It can be installed both as internal and as external. We will consider the design features of such facilities and the price of a spiral staircase.

Where are screw designs appropriate?

The spiral staircase is mainly perfect for small spaces, as they allow you to save a lot of space. They are especially convenient for the construction or technical support spans. Also, they can visually add height to the ceilings. They can be set as the center of the room, and close to a wall, as pictured to the right.

Due to its aesthetics and originality swivel design, it has some features. They are not as convenient as the main counterparts, and it can be problematic for the elderly or children to climb to the second floor. When placing spiral stairs in the house, you should also consider the need to lift furniture and other large items. Taking them upstairs with a turn is time-consuming, so such structures are recommended as additional.

Possible variants of structures

Before selecting the screw design for the house, you find out what types are available on the market. Stairs can be fixed with one of the following ways:

  • mounted to a supporting stand and perimeter walls;
  • installation in a control desk console without perimeter walls;
  • no support post, the ends of the treads are fixed in the curved stringers.

The second option, made of metal, is often used in construction. The price of the ladder of simple structure will be more affordable. As a stand, you should use a metal tube with thick walls. Its stairs will be in the form of a console; this does not need perimeter walls. Racks can be made of another material.
The products of the first type are characterized by wedge-shaped steps, the narrow end of which is mounted in support pillar, and the wide one relies on the perimeter wall. The thickened ends of the treads can play the role of the central support. When building the circular structures, the presence of risers is not foreseen. It is because winder treads have depth along the mid-line (an example of winder treads is in the photo below).
The models that do not have a support pillar in the center and resting on the bowstring are beautiful. They are curved in a spiral. However, this configuration is characterized by the complexity of manufacturing, and the cost will be higher. An example of this design is in the bottom photo.


The differences in the mounting steps and device support post

If the inner side of the stage is attached to the support post, then the outside fixation is carried out with:

  • rails;
  • bowstring;
  • combined system.

Rails are spacers that are installed on the outside of the steps. They provide a secure fit, but the screw design looks airy. The bow is a curved metal or wooden strip which holds the outer ends of the steps. It can act simultaneously as the fence.

An interesting design solution is the spiral stringer which frames the inner ends of the steps and performs the function of the support post.

There are often models, the steps of which are mounted on the stringer, as in the photo on the right below. The stringer is bearing beam which supports the tread on the bottom. It is more reliable to mount to walls. It is performed by the preformed grooves or by the installation of special pads. This option is possible only in the case when the structure is positioned in the corner of the room. The narrow side of the stage is fixed to the central support.
The device of the central bearing element can be different. There are two types of support stands:

  1. solid;
  2. patterned (photo is above).

The stages are joined to whole racks by welding or special brackets. As an option, the metal pillar is welded with beams, or console, which is the basis for the treads. Patterned racks are separate, metal, prefabricated fragments, between which the steps are mounted. In the end, the whole construction is obtained, and its cost is affordable. Its installation is performed without the involvement of installers.

What determines the outlines of the design?

Spiral staircases perform many different shapes. Round options are well spread. There are also square and polygonal models. A significant role in determining the form of the structure plays its whereabouts.

The round shape is preferable for centrally located structures of the. Square or octagonal variations are mounted around the walls. It should be noted that this configuration provides additional space savings.

The advantage of the square aperture to the circular steps is that its finishing is much more comfortable. It is essential to consider when constructing it with your own hands. A round gap will require curved elements for decoration. Facing beam is made of veneer. You will need stops and metal arc to give it a bend. The finished product is mounted in the opening, is fixed with corner plates and is made plinths.

The starting price for competitive ladders made of metal or wood of conifers is about 30-40 thousand rubles. Calculating the cost for a spiral design, you should take into account the fasteners. Their choice is closely linked to the total dimensions of the product. As a result, the price is formed depending on:

  • cost of materials;
  • design features;
  • size;
  • decorative design.

The cost depends on the selected materials and decorative elements. If the price of products made of pine is still available, then the screw-down model with steps made of oak wood will cost at least five times more expensive. The design is carried out with the materials, the cost of which is above. These include natural stone and glass. Of course, the value of construction with a similar decoration is also increased.

Some tips on installation

If you want the stairs to be the most convenient, it is worth considering the following advice from professionals and set standards:

  • On the middle line, the minimum depth of treads should be 200 mm.
  • Steps without risers are used for the screw and half-screw structures.
  • The minimum diameter of the support post is 50 mm.
  • The dispersion between the turns must not be less than 2 meters.

Screw design can be matched to virtually any interior. The room is decorated in country style, suitable three-dimensional wooden structure. Whereas a neat metal staircase will be harmonious for the direction of modern. A variety of models with a wider price range allows you to make the best choice.
