Making and installing a screw structure with your own hands
Many manufacturers offer screw designs that are easy to transport and assemble on site. In this case, home master it remains only to take care of the reliability of the fastening of the support post, steps and railings, so that the installation with your own hands is carried out in accordance with the instructions and safety requirements. Assembly of the finished screw structure You can also use ready-made wooden steps. rectangular, which are quite easy to adjust to the dimensions obtained in the calculations. After finishing, the edges should be sanded carefully. Based on the idea of the master, the steps can be covered with stain and varnish or paint. Moving on to making and installing a bowstring with your own hands, it should be borne in mind that it is extremely difficult to give wooden parts a bent shape. For this, a special technology is used, in which the wood is subjected to soaking, shaping and drying in a fixed state. An alternative would be to connect the individual segments into a single string. 
Observing the necessary standards and following the instructions of qualified specialists, every master who is familiar with the principles of woodwork will be able to manufacture and install a spiral staircase. For a more complete picture, we also recommend that you familiarize yourself with.
Modern spiral staircases, distinguished by their special originality, also have a number of practical advantages and stand out noticeably against the background of traditional (marching) designs. Firstly, they take up much less space in the room, and secondly, for their construction you will need much less material than it is spent on a regular staircase.
When building a spiral staircase to the second floor, you will have to take into account a number of such specific parameters as:
- center post design;
- way of fastening steps;
- configuration and height of restraining handrails and balusters and much more.
Note that the construction of a staircase made of wood or metal is quite within the power of even a beginner.
Operating experience screw structures suggests that the most convenient are stairs with a span of about one meter. As a result, the diameter of the entire screw structure (taking into account its placement around the central post) should be about 2.3 - 2.4 meters.
Of particular interest are the economical staircase structures, the steps of which are fixed on the central post and equipped with helical handrails mounted on balusters. Compared to this option, ladders with other types of support (without a center post) are more complex and cost you much more.
With regard to the shape of the screw structure, it does not have to be round in cross-section. You can also select a polygon with sides adjacent directly to the walls. The steps can be fixed in the thickness of the wall using special hanging mounts(overlays).
As a center pillar metal structure an ordinary pipe billet with a diameter of 50 millimeters with walls at least 4 mm thick is used. In the "wooden" version, the role of the central post is played by a column made of some kind of durable wood. In addition, popular materials such as concrete, brick or natural stone can be used to equip the B-pillar.
Railings for handrails can be made from both glued hardwood and common metal... In some ladder structures all of the above materials can be present in combination. Like railings, the gangway can be made of both wood and metal (it is even possible to make them from a thick tempered glass). For the manufacture of stairs, any Construction Materials, characterized by high strength indicators.
Stages of work
The order of work:
- First of all, the installation of the central post is carried out, on which the intermediate bushings are subsequently fixed together with the treads.
- After that, steps are evenly distributed around the entire circumference of the structure being erected.
- Then you can proceed to the installation of support brackets, installed in series on each of the rising steps. In this case, the last stage is rigidly fixed directly in interfloor overlap.
- At the final stage of work, the balusters are installed and the handrails are rigidly fixed.
At the end of all these operations, you will receive a ladder structure, ready for use.
To obtain a safe, durable and comfortable design, the following guidelines should be taken into account:
- We advise you to exclude such an optional detail as risers from the staircase design. In this case, the foot will not slide off the steps, even in the narrowest places.
- The lifting height of the ladder must ensure the possibility of free movement along it.
- The rack must be located on a support platform capable of supporting the total weight of the structural elements and at least two people. At the same time, its fastening in place should be as rigid as possible.
- The presence of an overlap between adjacent steps will additionally strengthen the structure under construction; for this purpose, it uses special brackets mounted between the front and rear ribs of adjacent steps.

Nikolay, Nizhny Novgorod asks the question:
Good day! I recently built in the country spiral staircase to the second floor. And when making handrails for her, I ran into a problem. Straight railings are not suitable for my design, a special semicircular shape is needed, since there are children and elderly people in the family, for whom this is of great importance. The staircase itself is made of metal, so I want to make the handrails also metal. Although if there is uncomplicated way bend wood or plastic, I can use them too. Please tell me how to bend a handrail for a spiral staircase in a simple way... It is desirable that I be able to do this myself and as quickly as possible. Thanks in advance.
The expert answers:
Hello! Nowadays, very often, instead of marching, they prefer the construction of a spiral staircase. You can, of course, turn to specialists who will fulfill your wishes in their workshop without any problems. But if you decide to find out how to bend a handrail for a spiral staircase yourself, please note that the handrails must be strong and safe during operation. The rules for bending a handrail depend primarily on the material from which you want to make it.
If you have chosen a tree, then there are two ways to bend it to the shape you need. You can dip the workpiece into boiling water and soak in it until the wood is completely soft. After that, you bend it to the shape that you need, fix it in this position and wait until it dries well. It is advisable to bend in this way when the thickness of the wood will not exceed 3 cm.
You can glue individual thin veneer parts by laying them directly on the steps close to the uprights in order to accurately repeat the bend. Finished construction coated with glue, wrapped in foil and attracted with clamps. When the glue is completely dry, the veneer is released from the clamps. The finished handrail, starting from the top, is screwed to each post.
When working with wood, remember that after bending the material must be impregnated with an antiseptic, covered with a layer of linseed oil, and after it has dried and fastened to the railing, varnish or paint these parts of the stairs.
Plastic handrails can be bent with construction hair dryer... Hot air is directed to the workpiece and gradually, as it heats up, bends it to the desired shape. The main thing is that the plastic does not melt. Therefore, control the supply of hot air from the hair dryer.
There are also two ways to make metal railings. If you have the opportunity, you can heat the metal in a special forging furnace and use a hammer to give it the desired shape. At home, you can clamp the metal strip in a vise and use a hammer to shape it.
Now you can choose for yourself the best option how to bend handrails for a spiral staircase. All of the above methods are simple and affordable, allowing you to do the work of bending handrails with your own hands at home without unnecessary financial costs.
If the staircase consists of at least three steps, it must necessarily be fenced, and the railings are equipped with handrails, which are easy enough to pick up when it comes to straight marching flights. But a screw product needs a radius fence with curved handrails, which greatly complicates the task. Finding a solution will help you contact the "Railing Empire". Production of protective structures and their implementation according to affordable prices- the main specialization of the company, so we can make a handrail for a spiral staircase of absolutely any complexity.
Our price: from 8,000 rubles
The main function of connecting structures between floors is to ensure safe comfortable movement. This means that the railing should be comfortable to hold on, so the railing should be adjusted to the size and height of the balusters. In linear structures, it is not very difficult to achieve an accurate fit, even at home and artisanal conditions. But the spiral staircase requires the participation of qualified specialists, who have professional equipment at their disposal.
It is worth paying attention to the aesthetic aspect. To ensure that the handrails are consistent with the overall interior concept, it is advisable to consult with experienced designer... The exact correspondence of shape and size turns out to be important in terms of aesthetics, as well as the quality of installation. “Empire of Railings” is well versed in the nuances of radius fences, therefore, having ordered a handrail for a spiral staircase from us, you don't have to worry about the result.

The choice of material for the handrail of a spiral staircase
When choosing a material, one should be guided not only by aesthetic considerations, but also by the operating conditions. Despite the fact that the installation of spiral staircases is carried out, as a rule, during indoor areas, you need to pay attention to the probability high humidity, temperature extremes and other factors that can cause negative impact... But there are also universal options... For the manufacture of stair railings and handrails, we use popular materials, the individual characteristics of which can be checked with the managers by phone:
- Stainless steel;
- Natural wood;
- Plastic (PVC).
Regardless of the material used in the manufacture, handrails are carefully processed to protect against aggressive factors and ease of use. With the help of special equipment, they are given an individual configuration and form, agreed with the customer. If you have not yet become one, call right now so as not to waste any more time. A metal, wooden or plastic handrail for a spiral staircase, ordered from "Railing Empire", will be pleasant to the touch, reliable and beautiful.
If you are going to equip a spiral staircase with your own hands, the drawing must be prepared in advance, this will allow you to carry out the work, avoiding mistakes. As a feature of this design, the steps are reinforced radially. This concerns a real or imagined center. If you project a staircase onto a floor surface, you can get a polygon or circle. A spiral staircase can be made with your own hands from metal, the drawings should definitely be considered before this. Choosing such constructions, you may prefer one of the varieties of the system. In this way, the steps can rest on the B-pillar and on the perimeter wall surfaces. In other versions, they can only be attached to the support column, which is located in the center. In some cases, the steps are supported by a guardrail or bent bowstrings, among other things, they can be pinched in the support post.
Manufacturing features
If you build a spiral staircase with your own hands, the drawing will allow you to do the work correctly. You can borrow one or another option from this article. Such structures take up little space, for example, with a step width of 1 meter, the diameter of the structure will be 2.2 meters, this includes the central support. In fact, the structure will take less than 2 square meters on the floor surface. When designing a product, you can give it a different angle of inclination, most often it does not exceed 45 degrees.
What you need to know before starting work
If a spiral staircase is to be made with your own hands, the drawing should be prepared by you even before the start of work. However, it is important to take into account that such structures do not have very wide steps, this indicates that movement along them will be difficult, it is important to be careful while doing this. It will be quite problematic to miss two people who meet on the spiral staircase. It is also very difficult to move bulky objects on it. This suggests that it is more rational to use screw structures in those rooms in which there is no heavy traffic. A lot of effort will have to be made to manufacture, since the elements and assemblies are more complex when compared with conventional ones.
Preparation of materials
If you make a spiral staircase with your own hands, you can consider the drawing for it by reading this article... However, it is equally important to familiarize yourself with the technology of the process and prepare all necessary materials... You should not be limited in the choice of material: maple, beech, and also oak are suitable among which. You can stock up on profiled or sheet metal.
Stair design
The structure should be devoid of a riser, which is a vertical element located between adjacent steps. This will prevent the foot from slipping when moving. The tread in the middle should be 20 cm or more. I must admit, quite often today spiral staircases are made by hand. Drawings, photos will help you make the right choice design features... In order to ensure the reliability of the step attachment point, the diameter of the average support leg should be five centimeters or more. The height between the branches must exceed the height of a person, this figure is equivalent to two meters or more. This eliminates the need to bend over when using the lifting mechanism. As for the full turn, there must be at least 12 steps in it.
Features of the calculation
Before making spiral staircases with your own hands, drawings are prepared by craftsmen, this allows you to exclude many mistakes, which can be very difficult to cope with. You can take as a basis the parameters that are presented below.
The height of the floor, which is measured from the floor surface of the first floor to the base of the floor of the second floor, is equivalent to 3 meters, while being equal to one meter. The diameter of the post in this case is equivalent to 20 cm. Now you can determine the diameter of the structure. This figure will be made up of the diameter of the support post and two steps, or rather, their width. Thus, the following calculations will need to be made: 2x1.0 + 0.2. Ultimately, you will be able to get a value of 2.2 m.
When spiral staircases are made by hand, drawings are prepared by home craftsmen, as a rule, independently. Having determined the diameter of the structure, it is necessary to draw a circle. At the next stage, the radius of the trajectory of movement is calculated. To do this, it is necessary to divide by 2 the diameter of the support post, to which the width of the step must be added. The calculation will look like this: (1 + 0.2) / 2; the required value is equivalent to 0.6 m.
The next step is to calculate the number of steps that will fall on 1 turn. To do this, the length of the trajectory of movement must be divided by the Final value is 18.84, while the calculation is as follows: 2x3.14x0.6 / 0.2.
If you are going to make a screw, then it is important to determine the height of the step. The coil height must be divided into 19 parts. The step between the first step and the last step of the loop must be greater than the height of the person. You can take into account a figure equal to two meters, to this value you need to add 5 cm, this will allow you to get the height of the loop, the calculation looks like this: 2 + 0.05; the result is a value of 2.05 m.
It can be determined by the formula below: 2.05 / 19. The figure after the calculations is equal to 0.11 m. The final number of steps will be equal to 28 pieces: 3 / 0.11. The result is a figure equal to 27.3. It should be rounded.
You can take for the main the following parameters stairs. The lifting height is equivalent to 300 cm, the diameter is 220 cm, the inner diameter is 20 cm, the total angle of rotation is 510 degrees, the thickness of each step is 5 cm, the step height is 11.1 centimeters. As for the angle of the step, this figure is 18.9 degrees, the length of the step is 100 centimeters.
Installation
If you are going to make a spiral staircase to the second floor with your own hands, then it is important to familiarize yourself with the technology of the process. Initially, the stand is installed and fixed, which is located in the middle. In the next step, you can start installing the steps and spacers. The master needs to fix upper part structures, and then strengthen the railings and handrails. If you are going to make a staircase that has a cantilever pinching of the steps, then beech can be used as the material. All blanks can be cut with lathe designed for woodworking. Handy will also come in handy electric tool... If you do not have such equipment in your arsenal, then you can order the preparation of parts from the master. The plumb line will allow you to transfer the corner point of the opening to the floor surface. This will be the starting point for defining the support position. On the base of the floor, it is necessary to draw a line that is parallel to the opening cut in the ceiling.
When screw drawings are made, you have to prepare them yourself or order them from a professional. In the next step, a cylindrical element and a starting stage must be put on the steel core. The rest of the elements are installed according to the same principle. After you have managed to assemble the B-pillar and steps, you should fix the upper platform. Next, the railing posts are installed. The steel core bolt passes through two stages and ends slightly above the uppermost stage.
Final work
You can make a spiral staircase with your own hands from metal, but for this you need to have the skills to work with welding machine... If you decide to use wood, then at the last stage you can paint. To begin with, the surface of the stairs is cleaned with sandpaper, then it is cleaned of dust and covered with stain.
Features of the manufacture of a metal staircase
A spiral staircase can be made with your own hands from metal, drawings of such structures can be drawn up by professionals. The assembly of the system must begin with the installation of the central post. After that, bushings are put on, and then washers and the steps themselves. After this part of the work is completed, the steps should be deployed around the rack to the required distance. Now it is the turn to attach the brackets. The upper step is fixed to the floor. When a metal spiral staircase is made with your own hands, the drawings will allow you to comply with the technology. At the last stage, the railings are mounted, as well as handrails.
