Calculating the stairs to the second floor is a standard task for those who independently design their own Vacation home or a dacha. Fortunately, it is not as complicated as people say. At the right approach to the question, as well as studying the necessary literature, you can do the calculation of the stairs to the second floor with your own hands within just a few hours. In order for you to be able to cope with it easily and quickly, you need to familiarize yourself with the basic techniques of designing a staircase for your home. Let's consider it for various types of construction.

Calculation

The technique used to calculate the stairs to the second floor of the house depends on such parameters as the type of structure, its angle of inclination, the number of steps, their width, as well as others design features sample. Before moving on to this matter, you will need to calculate:

• The height of the structure;
• Availability of free space for its installation (in some houses you can freely place ordinary flights of stairs, while in others only screw samples are free;
• Type of materials used for this purpose;
• Features of the operation of the finished model are the presence of small children or elderly people in the house, for whom steep stairs will become a real problem in the future;
• The need to carry heavy things upstairs (presence spiral staircase practically eliminates the possibility of moving large furniture to the second floor).

Of all possible options When installing a metal or other staircase in a house with your own hands, preference should be given to the one in which the calculation will be the simplest for you, and the task of installing the finished product will be the fastest. Therefore, it is always necessary to start studying and calculating projects with ordinary marching wooden stairs.

How to calculate a wooden staircase to the second floor

For example, consider the design of a classic wooden staircase in a cottage. The most simple option there will be a straight marching wooden staircase without turns with an average size of steps, as well as a rise height. The first thing to consider when calculating wooden stairs– this is the height of the second floor. This parameter will be central for further work.

Let's say it is 3 meters. A comfortable height of the steps should be about 19cm; if you make it larger, the staircase will turn out steep, and if it is less, the length of such a structure will be excessive. As for the depth of a straight staircase, you need to take a universal size of 30 cm - this is enough for a person to comfortably position his feet. Standard calculation of a wooden staircase in in this case will consist of defining several parameters:

• Loads on the supporting beam;
• Permissible deflection of the main staircase structures;
• Calculation of the opening height;
• Structure height;
• The number of steps, their width, as well as their depth;
• The angle of inclination of the stairs.

How to correctly carry out all the necessary calculations for such a wooden staircase design will be discussed below.

How to calculate a metal staircase to the second floor

A metal staircase to the second floor for a private house is calculated using the same technology as a wooden one. However, it is unnecessary to make several amendments: this model allows for a smaller step thickness while withstanding the same load. In order to obtain the most accurate values, we calculate the maximum load on the step and beams and, in accordance with them, determine the parameters of our future metal stairs By general formulas as for a wooden structure.

Calculation of the number of steps

For getting exact value the number of steps of a straight staircase, initially you need to determine the number of ascents; it can be calculated using the following formula:

Number of lifts + floor height / step height.

If the average height of our floor is 300 cm, and the steps are 19, we will have the following calculation results:

300/19 = 15.7, rounded to 16, taking into account the fact that our first and last steps may be lower.

Using the data obtained, we check the height of the step; to do this, we calculate the formula as follows:

3000/16=18.75 – round up to 19, we get the specified height of the steps.

So, the resulting number of spans is 16. The number of steps will be 1 less, since we do not count the first one in the frame, a total of 15 steps. In a similar way, you can calculate the number of rises both for a regular flight of stairs and for rotary and screw structures.

How to calculate the slope of a staircase rise?

Mostly stairs have an inclination angle of 23-45 degrees. Products with less inclination two-story houses are not used - they require a lot of space and in most cases are simply not functional. They can only be installed as an element of the facade group at the main march of the main entrance, nothing more. If it comes from attachments or quite cool designs, it can vary from 45 to 70 degrees. Fire escapes may have a higher value for this parameter.

It is not difficult to calculate the existing angle of the stairs in the house. To do this, it is enough to know the length of the space allocated for it, as well as the height of the ceiling. We build a triangle in which the staircase will play the role of the hypotenuse and, using the available values, calculate its size, as well as the angles. This method The calculation is quite accurate and makes it possible to determine the angle of inclination of any staircase.

Depth and height of steps: do-it-yourself calculation and design

Determining how to calculate the number of steps on a wooden staircase is not difficult, especially if you already know the height of the future flight. The main requirement for the steps of a metal or other staircase is that they must be comfortable and safe for movement. Therefore, when designing them, the following details must be taken into account:

• The height of the step should be no higher than 50 cm and no less than 10 cm;
• The width of the step corresponds to 300 mm;
• The overhang of the upper step over the lower one should be no more than 5 cm.

How to calculate a turning staircase?

Do-it-yourself turning stairs are a type of marching structures. Depending on the angle of their rotation, there are quarter-turn, half-turn and circular models (with a rotation of 90, 180, 360 degrees, respectively).

Calculation turning staircase different from designing a conventional structure. When carrying it out, you should be guided by the following parameters:

• The staircase must match the length of a person's stride. You need to take 63 cm as a basis.
• The slope of the stairs should be from 30 to 40 degrees;
• If the depth of the stairs is not comfortable enough for users, it can be increased by protruding the steps.

Also, when calculating a rotating staircase, you need to take into account such features as the height of the platform. It is most convenient to consider it as another step, but for this it must match the parameters of other staircases.

Calculation of a spiral staircase to the second floor

A do-it-yourself spiral staircase is one of the most popular designs, which can provide a fairly comfortable volume to the second floor if there is practically no space for installing a conventional flight of stairs. Calculating a spiral staircase is also not very difficult. To obtain the necessary parameters for the future sample, you must:

• Establish a center where the main support of the staircase structure will be placed.
• The width of the span is measured as the distance from the base of the staircase to its border; the same value is used to calculate the length of the step.
• The steps for such a staircase are made in a trapezoidal shape. At the same time, the width of their center should be at least 20 cm, and the widest edge - 40 cm. If you make this very edge larger, the stairs will most likely be simply inconvenient to use.
• As for the installation height of the stairs, it remains the same as for other types of construction - from 10 to 50 cm. However, for such stairs it is also advisable to keep the distance between the steps small for ease of use of the sample.

Assembling such a staircase with your own hands is easier than any other one. It is enough to install the stand and evenly secure the steps in a spiral. With certain skills in working with wood or metal, doing this yourself is quite easy.

The difference between the calculation of structures with winder steps

Stairs with winder systems have several design features:

• They can rotate at any angle up to 180 degrees.
• The depth of the steps of such a staircase is not the same everywhere: it decreases towards the center and accordingly increases at the edges.
• Most narrow end the step of such a staircase will be at least 10 cm.

Designs with winder steps are considered the most difficult to design, so their calculations are best left to specialists. If possible, you should not install such models in homes where there are small children or elderly people, since such a product will be inconvenient for them.

The given parameters are universal, but they are not really practical in all homes. Therefore, when calculating a staircase with your own hands, in addition to the “gold standards”, you must also take into account your personal characteristics of using the staircase. When creating a project, you can make the design more convenient and easier to implement using the following techniques:

• If you need to install a staircase that provides convenient lifting of a stroller, including a child's one, as well as the safe movement of elderly people and children, and the design will have an angle of 23 degrees, the classic steps can be replaced with sloping ones inclined plane– a ramp.
• When calculating the load on the stairs, it is worth relying on the values ​​​​that are given when a person climbs to the second floor, since they are always greater than those that we get during the descent.
• A comfortable staircase lifting angle of the structure cannot exceed 45 degrees. A staircase with an ascent angle above 45 degrees should be classified as an extension or folding one, and it is not practical to make it the main one for climbing to the second floor of a residential building. If a conventional design with a smaller angle does not fit in your home, it is advisable to make it rotary or screw.

Computer programs for calculating stairs

It can be extremely difficult to design a staircase online with your own hands, especially a spiral or turning one, especially with little experience in this matter. In order to cope with this task, you need to use a special software. Such applications allow you to:

• Receive accurate drawings of stairs from various angles, accompanied by all the online notes necessary for the implementation of the project;
• Calculate the dimensions of each step, the parameters of the angles, the overall dimensions of the stairs, as well as the dimensions of the top of the steps on the bowstrings.

Although online program calculating stairs allows you to get fairly accurate data; some adjustments for installing stairs in your home still need to be made. It is especially important to take this into account in cases where your premises have irregular shape, there are differences in the height of the ceiling or floor.

Online calculator for calculating the stairs to the second floor

Online calculator- another program that allows you to get fairly accurate numbers for calculating stairs online in the shortest possible time. Working with the calculator involves indicating such parameters as the type of structure, the height and length of the opening, the width of the platform, the number of steps, as well as their depth.

The online calculator may have a slight error in calculations. In order to level them out, it is recommended to manually recalculate the values ​​relative to your home, and also consult with specialists who have been developing such structures for a long time. It is also advisable to use, in addition to the calculator, several different programs for virtual calculation of stairs. Their average indicators, as a rule, turn out to be the most reliable in further work.

Using an online calculator to calculate stairs is not at all difficult if you understand the operating instructions and enter the necessary parameters correctly. It is very simple to calculate the stairs to the second floor using a calculator, and this can be done from any device with Internet access, for example, a tablet, computer, and the like.

The ladder must be strong, stable and properly designed. In order to determine the size of the stairs in a private house, it is worth taking into account the space between floors or, in other words, the thickness interfloor slab. First you need to decide on the shape of the structure. It is quite possible to equip a structure for lifting with your own hands, but in the absence of special professional skills, you should choose the most regular option straight stairs.

It will be reliable, convenient, and the construction process will not take much money and time. On average, such a staircase is suitable for rooms with a ceiling height of 2.5-3.5 m.

For the convenience of this piece of furniture, it is necessary that the flight of stairs be located on racks, and there should be free space under it. Thus, you can use square meters under shelves, placement of dark rooms and similar objects. To make the calculation correctly and independently, you need to use a simple and convenient formula, or in other words, simply take the optimal proportion - 2/1 relative to the length of the flight of stairs and the height of the room. For example, if the height of the stairs is 3 m, then the length should be 6.

To calculate the slope parameters, you need to rely only on personal preferences. Experts suggest choosing the most optimal angles tilt - 30 and 40 degrees. If the steepness is less, then the length will be very large, and in height it will look short.

What is an online staircase calculator?

Now many people have begun to use a computer method for calculating staircase parameters online. The program can be installed on an Android smartphone or on a laptop with any operating system. An example of recalculation is included in each application along with instructions for using the program.

In general, the development is quite convenient, functional and does not require too much time to calculate required amount material, width, including determining the slope.

The calculator table contains various columns and rows, each of which has a specific purpose. There is a calculator that designs the structure. In particular, by entering certain data into the table and clicking on the desired button, you can get an image of the future design in a couple of seconds.

The drawing will consist of:

• Side and top views;
• Drawings of steps;
• Bowstring drawing;
• Initial data.

Using the calculator, you can discover many new possibilities that will greatly simplify the development of your project. You can calculate and model a staircase on bowstrings, make the most accurate calculations of design details, get a diagram of the staircase in at its best and calculate the required amount of materials.

How to calculate the stairs to the second floor in a private house

The method for calculating and developing a conventional staircase is very simple and you can do it yourself. Namely, to design a staircase in your home, you need to accurately measure the ceiling opening. In particular, its width and length, including the height of the ceiling.

Planning of the staircase structure should be carried out taking into account:

• Dimensions of the future structure;
• Interior and general style of the room;
• Use of a specific type of materials;
• Load;
• The direction in which the movement will take place;
• The need to install additional support.

In any case, regardless of what types of materials will be used, the calculation of the staircase structure is carried out from measurements of the room. If the construction of a staircase is carried out at the time of renovation, then it is worth considering how the room will change, because the walls often become thicker, or the ceiling is slightly lowered. The dimensions of the stairs can be affected by the finishing of the floor, ceiling and other surfaces in the room.

Key Parameters of the Ladder Calculator

Thanks to modern technical developments It has become much easier to build houses, determine the location of pipes and stairs in the entrance, and more. Now anyone can independently make a 3D simulation and examine the future staircase practically from the inside.

It is through a computer that you can:

• Eliminate errors in calculations;
• Build the stairs correctly, taking into account the norms and standards of SNIP;
• Make the staircase comfortable and convenient even at the construction stage.

There are a huge variety of programs and each has its own type of interface, features for entering parameters and similar characteristics. It is worth noting that improved application models help calculate even such little things as the amount of fastening material.

Before using the calculator to calculate the staircase, as well as to generate its drawing, you need to decide:

• With the location of the structure in the house;
• Overlooking the stairs;
• With material.

In general, if the project is simple, then the calculations will not require much effort and time, because a direct structure can be installed anywhere in the room.

The design standards are the simplest, among which the following must be taken into account:

• Safety;
• Reliability;
• Convenience;
• Comfort.

Even when erecting a staircase in a private house, it is worth considering that it will be subject to great impact. For example, furniture, construction and Decoration Materials and it’s commonplace that a large number of people will get up, children can run around, and so on. That is why the stairs should be made as stable as possible and preferably with additional supports.

For compressed spaces and to save square footage in the room, you can use a spiral staircase.

It is worth noting that there are also staircase structures that are divided into double-flight and single-flight. They are large in size and are not intended for small rooms. Not only the base and middle of the building, but also the exit to the second floor must be thought out. The exit location or location of the hatch should be convenient so that there are no overhanging structures. For example, a sloping attic roof. This can cause serious head injury and more serious consequences. It is advisable to arrange a platform with railings at the top, which will protect the descent and make it more comfortable.

Rules for using the program: how to calculate the stairs correctly

The calculation of the rise to the top should be the most correct, regardless of what kind of staircase it is: straight, angular, vertical.

Other parameters are also not so important, for example:

• What kind of entrance platform will it be equipped with?
• Will it be convenient to wash the structure in the future?
• What kind of mass will be used during construction;
• Will the structure be made of wood or using metal panels?

The most important thing is that the structure must be safe and comfortable, as this can affect the health of those who will use the structure.

For example, too steep stairs and slippery steps can cause injury.

It is precisely in order not to spoil the future structure for going upstairs that you should use special programs that take into account all the nuances, including the size of the flight, the height of the opening and similar parameters.

Calculation of the stairs to the second floor: screw design

Spiral staircases can rotate 180 degrees.

These designs:

• Stylish;
• Beautiful;
• Compact.

It is the spiral staircase that is ergonomic and in a practical way, through which you can get to the second floor from the first. In addition, such structures are often chosen because of their aesthetic appearance, since they will look perfect in modern style or hi-tech.

To calculate the diameter of a spiral staircase, you need to multiply parameters such as the width of the flight by 2, and then add the size of the diameter of the base.

To determine the radius of the lift, you need to divide the width of the march by 2 and add the radius of the support posts. To make the staircase as comfortable as possible, you should not make it less than 800 mm. This way, you can move around without problems. As for the number and height of steps in a spiral staircase, they need to be calculated so that one person can freely ascend/descend and, if necessary, turn around on it. The height of the approach space is calculated by adding the average height of a person - 180 cm and the average depth of the tread - 20 cm. Next, all this is divided by how many steps one turn has. Then the height of the stairs is divided by the resulting value.

Staircase calculation program

The formula for calculating stairs depends on the type of structure, height, width, number of steps and material. For a private house you can choose stairs various types. In particular, curved ones, for example, helical, angular and different materials. It can be metal, wood, or plastic, but on a wooden or metal base. As mentioned earlier, screw structures are compact in size and add aesthetics to the interior. The calculation of the stairs is also influenced by the room and its features.

In particular:

• What it is used for;
• What parameters does it have?
• What is the interior like?
• How many turntables are needed?
• What should be the configuration of the steps;
• Where will the staircase be located?

Calculation of stairs (video)

Self-construction of stairs is very interesting activity, because you can use your imagination, it’s not easy to do metal structure, but an original forged model. There can be a huge variety of finishing and construction options, but the main thing is to choose only proven calculation methods. For example, a special online calculator.

During the construction of a residential building, the stairs need to be given Special attention still at the design stage. Unfortunately, not everyone understands this. The lack of a house design itself, a low-skilled team of builders and other circumstances often lead to the fact that outwardly beautiful staircase It turns out to be not very convenient to use, and if there are children and elderly people in the house, it is downright dangerous. I declare this authoritatively as the mother of a three-year-old hyperactive baby who regularly flew from the stairs of our attic apartment in the period from one and a half to two years. And all because the developer company was too lazy to be puzzled by compliance technical characteristics such important detail residential premises to established standards.

Staircase calculation program

So, the staircase in the house should first of all be comfortable. Especially if you plan to actively use it. And if you build a house without initially taking into account the required area to accommodate it, you will subsequently have to rack your brains over how to fit it into limited space so as not to one day count all the bones while descending from the second floor. In some cases, I will not say anything about the appearance of the structure, its appropriateness and harmony with the interior. Most often, if you do not initially think through the placement of the stairs and do not calculate the space required for this, you have to sacrifice something: either beauty or convenience. And sometimes both. To avoid such problems, use a staircase calculator. He will help you do everything necessary calculations online, select the optimal design parameters based on the available space, or, in the case of calculations at the house design stage, select the dimensions of the required area to accommodate the most comfortable stairs– and all this is absolutely free.

Calculation of a straight staircase on bowstrings

On this page you can calculate a straight staircase on bowstrings. A straight staircase takes up little space in width, but it requires quite a lot of space in length. It is optimally suited for placement in spacious rooms of low height and is usually installed along the wall, limited to the side by railings. To avoid loss usable area, you can place a dressing room under the stairs or arrange a small workplace(as well as a place to relax or something else - the flight of imagination is unlimited). A straight staircase consists of one row of steps - a flight and is called a single-flight staircase. Since stairs of this type are not equipped with intermediate platforms where it would be possible to stop and rest during the ascent, it is extremely important to calculate optimal size steps and their height. In this case, it is necessary to achieve such parameters in which walking up the stairs would be carried out in the rhythm of a step familiar to a person. The angle of inclination of a straight staircase is also important. The absence of platforms and turns that could detain a person in case of a fall leads to the need to try to make the stairs as flat as possible (inclination angle 30°-45°, no more).

Calculation parameters and results

The program for calculating stairs takes into account several basic parameters: Desired/current dimensions of the area that the stairs will occupy; Height of the room; The desired number of steps and their thickness; Projection of steps. Once all the values ​​have been entered, the online calculator will do the calculation. For ease of printing, it is possible to display the result in a separate window. In the calculation results you will see a general drawing of the staircase, a drawing of the steps template and a drawing of the bowstring with detailed explanations. If the parameters of the staircase do not comply with the standards and recommendations of SNiPs, which may make the staircase inconvenient to use, the program will report this and recommend making changes with specific instructions (for example, increasing the number of steps). This way, you can “play” with the parameters until you find the best option. A straight staircase is considered the most convenient to use, does not interfere with the movement of furniture to the upper floors and is the least dangerous. existing varieties stairs If you make it in strict accordance with the calculations and recommendations of our construction calculator, it will become a comfortable and safe structural part of your home.

Residents of any two-story house they want them to be beautiful and stylish. But besides this, it should be comfortable and practical. After all, it is the stairs that residents have to go up and down several times a day. And to make it as comfortable and functional as possible, you need to correctly calculate its layout.

Types of stairs

Today there are many configurations of staircases:

• Screw;
• Combined;
• On beams and others.

In addition, stairs are divided according to the materials from which they are made:

• Wooden;
• Steel.

Wooden stairs

Stairs made of wood are considered the most popular among residents. They are able to create a beautiful environment in the room and fill the house with comfort.

In addition, wooden stairs are very strong and durable. Also different high level resistance to external factors.

Types of wood that are most common in the manufacture of stairs due to their reliability, durability and long years of service:

• Ash;

If you want to save money, you can use pine to build stairs, but it is worth noting that this tree is not as durable as the above and can be affected by external factors.

Metal stairs

This material is also popular for making stairs. One of the main advantages of this design is that when constructing a metal staircase, it is possible to combine it with other materials, such as wood. In addition, making such a structure is much easier than a wooden staircase.

For manufacturing you will need the following components:

• Metal profiles;
• Metal sheets of different thicknesses;
• Pipes;
• Fittings.

Steel structures are distinguished by their positive characteristics:

• high reliability and durability;
• functionality, practicality and unique design;
• relatively low cost, quick production and installation attracts the attention of the consumer.
• There is no need to paint a metal structure, therefore there are no additional costs.

Spiral staircases

Such structures can decorate any interior with their airy curved appearance. One of the advantages of a spiral staircase is considered to be its compactness, so it does not have to take up much space in the house.

In addition, they are designed to be the most decorative and stylish. Such a staircase is easy to notice, because it can easily stand out even in a rich interior.

Spiral staircase structures are divided into:

• Structures attached to the central axis;
• Structures on stringers;
• Stairs on a bowstring.

How to calculate a staircase?

First, you need to choose the place where the structure will be located. You also need to decide on the choice of the staircase itself. Here the main criteria are practicality, functional qualities and the presence of empty space around this structure. The location of the walls is also one of the criteria in the selection of stairs.

To calculate the staircase construction, you should also pay attention to the design of the structure itself. To do this, you need to know exactly how much its width will be - from 1.5 to 3 meters. It is worth noting that the width of the staircase should be equal to the distance of the flight that is adjacent to it. The height of all steps must be the same height and have no bends.

Parameters you need to know when calculating the stairs:

• Height of steps;
• Width of steps;
• The slope of the stairs;
• Railings and fences;
• Interflight part of the stairs.

What should be the characteristics of the steps?

1. One of the parameters for calculating a staircase is the height of the steps. Their characteristics depend on the shape and geometry of the future staircase and the maximum height of the staircase structure.
2. The slope of the stairs and the distance from the railing to the wall must also be calculated correctly.
3. Width of space between railings- called the width of the march. Its average size is 90 cm. But if there is a railing on one side and a wall on the other, then the size of the march reaches 110 cm.
4. This distance can be total or final. Finish width - the size of the staircase without taking into account the fences.
5. The size of the march throughout staircase should have the same readings.
6. It is also worth calculating the width of the steps. As a rule, their width should have the same distances as the width of the march.

Calculation of the slope of the stairs

In cases where the angle of inclination is approximately 30-35 degrees, then this is considered an ideal case. But if this angle is changed, then the ladder can be used for other purposes.

Calculation of steps

The comfort of walking on the landing depends on how high the steps are located. Typically, the height of the riser is 15-18 cm. If you make the height higher, then going up and down will be quite difficult and inconvenient.

The depth of the step is considered optimal if it is approximately 30 cm. Its depth can be calculated using the formula:

2с + d = 60 – 64 cm

• WITH– riser value;
• D– width of steps;
• 60-64 – approximate step length.

They also make stairs, the steps of which visually hang over each other. This is done in small spaces to reduce space. This staircase takes on a light and beautiful appearance.

1. For correct calculation staircase geometry and the space between the marches, it is important to take into account that the distance of the entire construction, which is located in the marches, must be at least one and a half meters long. That's about two human steps. Width flight of stairs should be the same as the width of the steps.
2. To calculate the railings and fences you need know their characteristics. The approximate height of the railing is approximately 90 cm, and if the structure is screw-shaped, then 110 cm. The distance between the railings themselves should be no more than 13 cm. This width is determined to avoid the risk of body parts getting stuck between the railings.
3. This width also affects safety the entire staircase structure during its operation. The stability of the entire staircase depends on the width of the balusters; accordingly, the larger the width, the less stability there will be, and the less safety the structure will be.

How to calculate a turning staircase?

Before you start building a rotating staircase, you need to study all its qualities and differences from a simple one.

To correctly calculate a rotary modification staircase, you need to know the necessary parameters:

• The length and height of the entire structure;
• Number of simple steps;
• Number of turning steps.

Usually the number of turning steps is limited to three pieces.

Calculation of stairs with winder steps

In addition to simple steps, winder-type steps were often used in the manufacture of staircase structures. Before you start calculating the stairs, you need to decide on the location of the winder steps.

Also, when calculating, you need to observe some technical features:

• The smallest step width should not be less than forty centimeters;
• The smallest radius of curvature is thirty centimeters;
• In order to ensure safe conditions for walking, the line of passage along the entire staircase should be smooth with the entire march;
• The width of winder-type steps can be from twenty centimeters and wider.

Calculation of the cost of wooden stairs

In order to make the calculation, it is necessary to determine the necessary parameters:

• Material for its manufacture. It can be oak, pine, ash and others.
• The height of the staircase structure - that is, the distance from the bottom floor to the floor top floor. The calculation must be carried out in millimeters.
• Width of the landing. Also in millimeters.
• View of the stairs. You can choose straight, screw, with winder-type steps and others.
• Determine whether the materials will be treated with varnish or paint, and whether risers will be present.
• Measure the length of additional fences - railings. The calculation is made in millimeters.

So, let's say the owner decided to construct a wooden staircase with winder steps at 90 degrees. The material chosen was oak. Height of landing – 3000 mm, Width of stairs – 1500 mm.

Since the supposed staircase design will be located in the middle of the room, fences or railings will be used on both sides of the structure. This means that the length of the railing will be 6000 mm. A riser will also be installed, varnishing and tinting will be used. The required color was selected based on the samples and the customer’s request.
