State Standards and SNiPs for stair railings. Types and arrangement of fencing
When designing the rise to the floor, the parameters of the fences are taken into account, namely the height of the railings of the stairs, their dimensions, installation features and materials of GOST and SNiP. Well-designed railings that comply with standards ensure comfortable and safe movement both up and down the stairs.
Constituent elements
Railings and railings are an important element of every staircase design. Their presence is considered mandatory for spiral staircases and straight flights with more than three steps. They should also be installed outdoors. The main task of the fences is to ensure the safety of movement on steps and platforms. They block the open span, serve as a support and provide a feeling of comfort when moving. In addition, such a frame of the march gives it a complete look and creates special decorative forms, which is also important.
Regardless of the type of construction, the height must comply with generally accepted standards
The height of the railing and stair railing may not match. It all depends on the features of the design itself. The rules, for the most part, are dictated not by the design concept and interior, but by regulatory documents - GOST and SNiP.
To better understand their meaning, you need to understand the design features of the fences. Their main elements are:
- support stand;
- baluster;
- railing;
- internal filling.
Additionally, balusters can be installed - strips for fixing intermediate supports. Wall handrails consist of a support bar, a crossbar or railing and fasteners.
Materials used
When installing fences, it is important to take into account not only the parameters of the structure itself, but also the features of the materials used. First of all, this concerns the requirements of SNiP regarding fire safety. Fences should not be easily flammable. For this, either refractory materials or auxiliary impregnations are used. Particular attention should be paid to the internal filling.
Railings for stairs can be made of the following materials:
- tree;
- metal;
- plastic;
- combined (including with glass).
Glass must be strong, fire-resistant, free of cracks and chips, and if damaged, not form sharp fragments.
“Classic of the genre” - metal railings
For the railing, you can use the same materials as for the base part. In this case, a tree is considered an ideal option. It is important that there are no chips and burrs on the surface, it must be perfectly smooth. Metal railings should not contain rust. The best option is stainless steel, in particular for auxiliary transom handrails.
Height Requirements
When designing staircases, it is important to observe not only aesthetic standards, but also the standards and regulations of GOST and SNiP. These documents regulate the recommended design parameters in general, in particular, the fences.
One of the most important indicators is height. It should be sufficient so that a person does not fall over the railing, but at the same time comfortable for their use.
Minimum and maximum allowable stair railing heights
The height of the railings of the stairs at the level of 90 cm is considered standard. This indicator is not random - it is calculated on the basis of average statistical data regarding a person's height. This figure takes into account the requirements of safety and ergonomics, therefore it is considered optimal in most cases. If there are children in the house, it is necessary to additionally install a handrail, taking into account their height, usually its height is 50-70 cm.
Other Important Aspects
In addition to the height of railings and fences, SNiP and GOST establish other standards. It is also important to take them into account when designing, otherwise the staircase will not meet generally accepted standards.
Important parameters for designing stair railings:
Direct marches must be equipped with fences on both sides. This rule is irrelevant if the staircase is not too wide and at the same time it is adjacent to the wall on one side. In this case, only one-sided protection from the outer end is required. If their width allows two people to pass, a handrail is made near the wall. It is recommended to install continuous railings if possible.
Possible deviations
Far from always the rules established by GOST and SNiP are observed in full. This is fraught with an increase in the risk of injury to the structure and reduces the level of ease of use of the march.
In some cases, deviations from established standards are allowed. First of all, this concerns structures in homes where there are children, as well as people with disabilities or developmental disorders of the musculoskeletal system. So, it is allowed to install handrails at a level that is safe and comfortable for a particular person. In this case, it is important to observe the established relationships between growth and design parameters.
For children, additional handrails can be installed at the level of their growth.
Another important point is the height of the fence itself. There is no point in underestimating it in any case, but making it larger is another matter. This safety requirement is relevant for homes where there are people with mental disorders. In this case, the height of the ladder barrier can reach 2 meters or more.
As the height increases, the design becomes safer in some respects, but less convenient.
The ladder can be considered safe only if all established standards are observed. In private buildings, when doing work on their own, this is rarely checked, so all responsibility lies primarily with the owner of the dwelling. Do not ignore the rules, then the design will be not only safe, but also durable.
During the preparation of projects for industrial and residential buildings, state norms and standards are applied for the design of indoor and outdoor stairs. According to them, the result is completely safe to move. Particular attention in such projects is paid to the parameters of the handrails.
Required railing height
According to the norms, the minimum indicator for the elevation of fences is 90 cm. Such fences can be installed in residential buildings, administrative institutions, office buildings and branches, as well as in places of mass trade (shops, supermarkets, shopping centers). If the gangway is assembled for a two-story private house, the same conditions must be taken into account. But when installing steps, it is important to take into account not just comfort, but also the average height of a person living in this building.
There is a GOST for the height of the railing
Important! The emphasis is often placed on the tallest resident of the house. In this case, you can determine the best option, focusing on the gap from the floor to the palm of your outstretched hand.
In some cases, the supports are equipped with only a few steps. This number of steps is relevant for the porch of rooms with high attendance. There are requirements and standards for the height of such stair railings. According to state standards, the height of the railing of small steps should be 80 cm.
What determines the height of the railing
The main parameter of supports on stairs is to ensure the safety of people who will move along it. The height of the supports may be different, but it must be fully designed to fulfill its intended purpose. When choosing the height of the railing on the stairs according to GOST, the minimum norms of SNiP should also be taken into account. These laws specify clear rules that are completely dependent on the purpose of the structure in which the structure will be installed.
In this video you will learn how to determine the height of the railing:
General norms and standards according to GOST
The main criterion for the safety of steps is the length of the handrails that are installed on it. During the design of gangways and fences, the minimum requirements established by the GOST documentation should be taken into account. Only in some cases can they be slightly deviated from.
Basic norms:
- Width. This parameter should not be more than 7 cm, but the minimum may also be less than 3 cm. An exception in this case are structures that belong to front buildings. These designs can have a width of more than 7 cm. But, regardless of the deviations of the standards, a person who has lost his balance should quite easily grasp the support firmly and not injure his hand.
- Spacing between balusters. It cannot be more than half a meter. Sagging balusters are not allowed in any structures. In the event that the step of the installed balusters exceeds 12 cm, horizontal crossbars must be additionally installed to them. The exception is kindergartens. In them, the interval between the balusters is more than 12 cm.
- Parameters according to GOST. Minimum standards must be observed during the construction of steps with railings. Not in all cases, the dimensions of the railing for the stairs are observed. An exception may be structures with increased injury risk or uncomfortable use of supports during movement. In kindergartens, supports may be installed that deviate from the recommendations. Also, stairs can deviate from the standard height for handrails in houses with people who are limited in physical capabilities.
Deviation from the minimum requirements adopted in the state standard is allowed only if the parameters of people were taken into account during the installation of the gangway. For tall or short people, it is necessary to create supports of a suitable size, comfort for them is the basis during the use of steps.
Handrail height requirements, depending on the type of room
Many are interested in the question, what should be the height of the railing? There is no common denominator for the organization of work, as the minimum requirements for the installation of fences depend entirely on the type of room in which the installation will be carried out.
Norms of parameters according to GOST for different types of buildings:
- Preschool institutions. The most optimal height of the railing should be from 50 cm. If the buildings are frequently visited, then the gangways are equipped with additional supports with dimensions up to 90 cm. The vertical posts of the fences are also installed according to the standard. The documents state that the distance between the vertical posts of the handrails should not be more than 15 cm.
- Schools. According to the state standard, in such institutions, the dimensions of the installed structure are at least 1.2 m. In these institutions, the handrails protect the child from accidental falls. This is very important, because elementary school children actively move and run during breaks. If this is a school or an institution for mentally retarded children, a mesh with parameters from 1.5 meters is installed as a fence, which guarantees additional protection.
- Fire ladders. All buildings should be equipped with such structures, regardless of their direct purpose. At the exit from the building there should be a platform for the evacuation of people, which is fenced with supports with parameters of 1.2 meters.
- Outdoor installation sites. For such sites, handrails are provided according to the construction SNiP with a height of 1 meter.
Each institution has its own requirements.
The standard height of the railing on the stairs according to GOST
Any design is convenient to use only in cases where a certain distance is maintained between the main components, namely the risers and the tread. Such indicators are not fundamental, but it is recommended to comply with them for ease of use.
Steps in a residential area must also meet the following requirements:
- General dimensions of the riser and two risers. Data of this nature should be the same as the step distance of the average person. The step distance varies from 60 to 65 cm. According to the documentation, the elevation of the riser is 10-12 cm. As for the width norm, it should be from 20 to 40 cm.
- The standard indicators for the height of the railing on the stairs in a private house are considered to be from 90 cm. The width of the handrails should be no more than 7 cm, and the vertical balusters are installed at a distance of 12 cm from each other. If the interval between them is increased, horizontal crossbars are additionally used.
Attention! If such requirements were taken into account during the design, the use becomes more comfortable and, most importantly, safer.
In conclusion, we recall that during the manufacture of stairs and the installation of fences, it is necessary to comply with all the standards of the GOST and SNiP documentation. Do not forget about the use of high-quality material and the observance of the correct technology, because the comfort of operation of the structure and the safety of people also depend on this.
August 9, 2009
Modern building and technical standards prescribe to equip buildings with stair railings. These structures consist of several components, and various materials are used in their manufacture.
Types of fences
Design features of fences
According to established standards, a staircase consisting of three or more steps must be equipped with enclosing structures. If lifting is carried out along the wall, then in order to save free space, wall handrails are used. Their fixation is carried out at a distance of 5-7 centimeters from the wall.
Along with handrails and railings, balusters are the basic component of the fence. These are vertical bearing racks that can have a different shape. As a rule, they are installed at a distance of up to 900 millimeters with fastening from above in a step. If the flights of stairs are of sufficient width, the fixing of the bearing racks can also be carried out at the end of the step. The plane of the enclosing structure is taken out of the flight of stairs. Thanks to this, the width of the passage remains unchanged.
The space between the balusters is filled with vertical, longitudinal or inclined tubes or bars. It is also possible to use screen-type panels or glass.
Railings can be of both prefabricated and welded construction. The second option allows you to get a product without connecting seams. Such railings have a smooth surface without protrusions and look monolithic. In the manufacture of welded stainless steel structures, the argon-arc welding method is used. In the process of welding carried out in this way, the metal is not spattered, and the structure itself acquires increased rigidity.
If the width of the flight of stairs exceeds 1.25 meters, it is necessary to install a railing on both sides. And when arranging stairs with a width of more than 2.5 meters, railings are additionally mounted in the center.
materials
The use of stainless steel and glass in the production of enclosing structures is the best solution.
- Stainless steel products. Such enclosing structures have many advantages. They are resistant to corrosion processes and at the same time have an aesthetic appearance. The functionality and practicality of stainless steel fences makes it possible to install them in common areas. Due to their excellent hygienic properties, such structures are widely used in children's and medical institutions. Stainless steel railings do not need special care and do not change their characteristics under the influence of aggressive environments. Railings of stainless steel lattice fences consist of posts and parallel longitudinal crossbars (as a rule, their number varies from 2 to 8 pieces). The crossbars are fixed with holders, pass through the baluster or are welded directly into the rack. In the manufacture of such structures, pipes of different sections with a diameter of 8 to 25 millimeters are used. One of the most popular types of stainless steel railings are products with vertical infill between posts. Most often they can be seen in kindergartens and shopping centers. When choosing structures of this type, it should be borne in mind that the maximum distance between the elements should be no more than 100 millimeters (GOST 25772-83 p. 1.3).
- Glass railings. Such designs look aesthetically pleasing and stylish and look harmonious on almost all types of stairs, including spiral ones. Transparent, frosted, tinted glass panels in combination with stainless railings will be an excellent addition to a modern interior. Fixing glass between racks is carried out in various ways. The simplest of them is the use of clamping glass holders. They allow you to do without drilling glass. As a rule, clamping glass holders are used with racks of non-standard section. When arranging enclosing structures, different types of glass can be used: raw and tempered triplex, ordinary tempered glass, or a combination of raw and tempered glass. At the request of the client, it can be given any shade, decorated with a pattern, engraved or even backlit.
Requirements of GOSTs and SNiPs for railings and enclosing structures
- According to GOST 25772-83 (clause 1.2, 1.3), the height of lattice, screen, combined internal fences must be at least 900 millimeters. At the same time, the presence of handrails on the stairs of residential and public buildings is a mandatory requirement (SNiP 2.08.01-89 p. 1.17; SNiP 2.08.02-89 p. 1.91).
- The design and manufacture of fences should be carried out in accordance with the parameters reflected in GOST 23120-78 (p. 1, 2).
- Elements of the enclosing structure should not have sharp protrusions and edges.
- Railing handrails in residential and public buildings must withstand a load of 0.3 kN / m, which is 30 kgf / m (SNiP 2.01.07-85 p. 3.11).
- Enclosing structures must comply with fire resistance requirements (GOST 30247-94 p. 5-9).
- Fire safety standards prescribe to observe a certain width of the flight of stairs (SNiP 2.08.02-89). According to paragraph 1.96, in public buildings, it must correspond to the width of the exit to the staircase from the most populated floor. If we are talking about buildings in which the number of people simultaneously staying on the floor is on average 5, the width of the march cannot be less than 0.9 meters. For buildings in which there are up to 200 people on the most populated floor at the same time, this parameter is 1.2 meters, and more than 200 - 1.35 meters.
- Along with fire resistance, enclosing structures must be reliably protected from corrosive processes (SNiP 2.03.11-85 p. 5; SNiP 3.04.03-85 p. 2.1-2.8, 3).
- According to GOST 25772-83, clause 1.3, balcony railings must meet a number of requirements:
The company "PerilaGlavSnab" manufactures stair railings with a guarantee of quality. Having our own production base allows us to offer our customers modern technological solutions in this area and fulfill orders on time.
Question:
According to SP 1.13130.2009, p. 5.4.20, amend. 1 and SNiP 31-01-2003, p. 8.3 - The height of the railings of stairs, balconies, loggias, terraces, roofs and in places of dangerous drops must be at least 1.2 m. Flights of stairs and landings must have railings with handrails.
According to SP 59.13330.2012, clause 5.2.15, handrails should be placed at a height of 0.9 m.
In accordance with SP 54.13330.2011, clause 8.3, the height of the railings of external flights of stairs and landings, balconies, loggias, terraces, roofs and in places of dangerous drops must be at least 1.2 m. Flights of stairs and landings of internal stairs must have fences with handrails at least 0.9 m high.
According to SP 1.13130.2009 “Fire protection systems. Escape routes and exits”, clause 4, paragraph six of clause 4.3.4 shall be amended as follows: “If the height of stairs is more than 45 cm, fences with a height of at least 1.2 m with railings should be provided.”
At what height should the railing be, and what types of stairs do these requirements apply to?
Answer:
The height of the railings of external flights of stairs and landings, balconies, loggias, terraces, roofs and in places of dangerous drops must be at least 1.2 m.
Stair flights and landings of internal stairs must have railings with handrails at least 0.9 m high.
Rationale:
The height of the railings of external flights of stairs and landings, balconies, loggias, terraces, roofs and in places of dangerous drops must be at least 1.2 m in accordance with clause 8.3 of SNiP 31-01-2003.
Flights of stairs and landings of internal stairs must have railings with handrails at least 0.9 m high in accordance with clause 1.6 “GOST 25772-83. Steel railings for stairs, balconies and roofs. General technical conditions”.
GOST 25772-83 is voluntary, but this is the only document referenced by the above SNiP, which sets the height for flights of stairs and landings of internal stairs.
During the transition period, SP 1.13130.2009 does not cancel the effect of SNiP 31-01-2003 (letter of the Ministry of Regional Development of Russia dated 15.08.2011 N 18529-08 / IP-OG).

Calculate the height of the railing
Railings are railings along the edges of the stairs that are installed for safe movement along it. The height of the stair railing is a very important indicator, and it must be taken into account when designing. Such structures can be used not only to protect steps, but also in the construction of balconies, terraces, etc.
In addition, the railing of the stairs can act as handrails and help when climbing or descending stairs. Their length should be commensurate with the length of the steps.
What are railings made of?
In order to properly assemble the stairs, you need to know well all the elements that are necessary for construction. In addition to steps, there are many more components. Railings, for example, consist of:
- racks (in other words - balusters),
- handrails,
- handrail,
- baluster planks,
- fasteners.
When choosing materials for the construction, one should not forget about the main function of the railing - protective. This means that they must be of high quality. Particular attention should be paid to the railings on the balcony, because their instability may well cost lives. Falling from several steps is one thing, but from a height of at least the 2nd floor is quite another. Therefore, maximum measures must be taken.
How many fences do you need
For narrow stairs, the width of which is not more than 125 cm, the railing is usually installed on one side only. For wider steps, it is better to put a railing on both sides, so you can pass up and down at the same time.
Another option is to install an additional handrail along the center of the stairs so that traffic flows are separated. This method will be functional on stairs with high traffic of people.
Which stairs need railings
Do not forget that any staircase that is not equipped with a railing is dangerous to operate. However, in some cases, you can do without them. So, length is very important, and handrails are usually neglected when building short stairs (less than 5 steps).
For fencing higher structures, it is recommended to make stable supports that will not allow them to fall from the structure. In addition, it is very important to calculate their height.
Railing height
In any residential premises, the height of the railing should be at least 90 cm. At the same time, the distance from the wall to the railing should be at least 40 cm. On the landing, the height of the fence should also be 90 cm.
Note:
Such parameters do not exist by chance, because it is this size that is ideal for the growth of an average person.
How to be with children? For them, they often put additional railings about 65 cm high.
Supports on the terrace
Of course, various decorative features in the design of the porch or the original design of the railing can make adjustments to their height. However, it is highly undesirable to violate the values recommended by the builders.
The main reasons why you should consider the advice of experts:
- If the railing is lower than recommended, then it will be inconvenient to use and dangerous.
- If the railing is higher than recommended, then it will be less comfortable, but safer.
Compliance with the State Standard
According to GOST 25772-83, the presence of handrails on the stairs of public buildings and residential buildings is a prerequisite. The height is also specified, and in order to comply with the standard, it must be equal to or greater than 900 mm.
Railings for balconies are regulated by GOST as follows:
- In preschool institutions, they must be at least 1200 mm.
- On smoke-free staircases - at least 1200 mm.
- In buildings whose height is up to 30 m - 1000 mm.
- In buildings with a height of more than 30 m - 1100 mm.
Among other requirements of the standard, it can be found that sharp protrusions are not allowed on fence elements. Railings must also be fire resistant, for this you should use stainless steel or glass. The length of the step is built taking into account many parameters.
Appearance
When building a house, the aesthetic side of the stairs is not in last place. In this regard, many seek to give the handrails an unusual look or make beautiful steps. Forms of balusters and pillars come in different designs and from different materials.
But the basis for choosing building materials should still be quality and sustainability.
All handrails must be smooth, that is, without burrs. And the joints should be well adjusted. The posts should be installed with the greatest possible rigidity, because the reliability of the fence depends on this.
So, we talked about how important it is to install strong railings for stairs, terraces, on the balcony and how to calculate their height. Did you learn something new from our article? What advice was the most helpful? We will be grateful if you share your personal experience in making stair railings or how you yourself tried to calculate their height!

Requirements for fire escapes in accordance with GOST R 53254-2009
During the construction of multi-storey buildings, houses and structures, it is necessary to provide special ways to ensure the exit of people to a safe place in the event of fires and other emergencies. One of the means of evacuation and access to the roof are external fire escapes. Requirements for their production, installation, operation are established in state standards, in particular, in GOST R 53254-2009.
Varieties of designs
Two types of stairs are made:
Marching, considered the safest, can be used for descending and ascending to a great height, from 20 m. They are also installed in places where the roof height drops more than 20 m. They are intended for mass evacuation of people and access for firefighters to the fire site. Consist of alternating marches and platforms.
Vertical structures are used to extinguish fires and lift service personnel to the roof. They consist of two longitudinal parallel bowstrings made of metal, rigidly connected by transverse steps. They are installed on buildings with a height of 10 to 20 meters and in places with a difference in roof height from one to 20 m. At a height of more than 6 m, they have a protective structure that prevents falling.
Requirements for the installation of evacuation structures
State standards, which indicate the main provisions for the installation of fire escapes:
- GOST R 53254-2009 “Fire fighting equipment. Stairs firemen external stationary. Roof railings,
- SNiP 2.01.02-85 "Fire safety standards".
For buildings with a height of more than 10 m (from ground level to the parapet or cornice), exits to the roof are provided through structures mounted on the outer wall.
Residential buildings, administrative and public buildings with attic coverings, for every 100 meters in length, must have access to the roof. Buildings with non-attic pavements - one exit for every 1000 square meters of pavement.
Warehouses and industrial buildings are equipped with fire escapes every 200 m of the perimeter or more often.
In places where the difference in roof height is more than one meter, stairs must be installed.
It is allowed not to install structures for evacuation on the main facade of the building if:
- the width of the building is not more than 150 m,
- on the side opposite the main facade, a fire-fighting water supply line is installed.
If the building is one-story and has an area of less than 100 sq.m, it may not have access to the roof.
Rooftop fire escape. GOSTs and SNiPs
The STK Construction company manufactures evacuation structures according to TU 5262-002-92716048-2012 in accordance with GOST R 53254-2009, GOST 23118-2012, GOST 23120-78, as evidenced by the certificate of conformity. Production is carried out in the factory. To ensure the durability and strength of the joints, welding is carried out on special equipment.
Our stairs are made of non-combustible materials and are reliably protected from corrosion.
Installation, placement of structures is carried out in accordance with SNiP 3.03.01-87, GOST 23118 and the Draft Code of Rules “Fire protection systems. Evacuation routes and exits.
Requirements for welds are established in GOST 5264 and SNiP 3.03.01-87. Rust and scale are unacceptable on their surface. Also, sharp protrusions, edges, burrs at the joints of structural elements are not allowed.
The protective coating class according to GOST 9.032 must not be lower than the fifth. The remaining requirements for corrosion protection are according to the same standard and SNiP 2.03.11-85.
Evacuation structures must be securely attached to the wall of the building and provide the required strength and rigidity during acceptance tests and for the entire period of operation.
There are special requirements for the material for the manufacture of flooring platforms, steps - it must provide a strong grip of the sole with the base, so that during movement a person does not slip, is not injured and does not fall from a height.
Vertical stairs
Vertical structures located at a height of more than 6 meters are made with a fence. It consists of semicircular arcs welded to the bowstrings. In this kind of tunnel made of rigid metal bars, it is much safer to go down and up to a height.
The following sizing requirements apply:
- The minimum width of the stairs is not less than 0.6 meters.
- The distance from the ground to the top step is at least 1.5 meters. It is allowed to make the lower section retractable if its reliable fixation is ensured in working condition.
- Platforms for access to the roof are made with a length of 0.8 m or more. It should be fenced with railings, located flush with the roof or slightly higher.

"P. 4.3.4 SP 1.13130.2009. If the height of stairs is more than 45 cm, railings with a height of at least 1.2 m with railings should be provided.
Pulling fragments of text from a single paragraph is sometimes not very correct. Here is the full text of the paragraph:
“4.3.4 The clear height of horizontal sections of escape routes must be at least 2 m, the width of horizontal sections of escape routes and ramps must be at least:
0.7 m - for passages to single workplaces,
1.0 m - in all other cases.
In any case, the escape routes must be of such a width that, taking into account their geometry, a stretcher with a person lying on them can be easily carried along them.
In the floor on the escape routes, height differences of less than 45 cm and protrusions are not allowed, with the exception of thresholds in doorways. In places of height difference, stairs with at least three steps or ramps with a slope of no more than 1:6 should be provided.
With a ladder height of more than 45 cm, railings with a height of at least 1.2 m with railings should be provided.
On evacuation routes, it is not allowed to install spiral staircases, stairs completely or partially curved in plan, as well as winder and curved steps, steps with different tread widths and different heights within the flight of stairs and stairwells.
Now it is clear that here we mean stairs on the floor height difference. This has nothing to do with the railings of stairwells.
Sincerely, Aquarius
Well then, in SP 1.13130.2009, I found specific requirements for buildings of certain classes of functional fire hazard:
5.2.15. Handrails and fences in the buildings of preschool institutions must meet the following requirements:

The dimensions of fences and railings are approved in accordance with ergonomic requirements. When designing protective structures for public buildings, entrances of high-rise buildings, private houses, it is necessary that the requirements of building codes and rules of SNiP are observed. This is necessary to ensure the safety of their operation.
Requirements for the height of stair railings
GOST 23120-78 states that any ladder structure, the height of which is more than three steps, must have a side railing, this requirement does not apply to external capital structures (meaning the porch of the building). Stair flights are equipped with handrails for maximum safety of people, as well as for the most comfortable descents and ascents. Height is one of the most important indicators. It should be sufficient so that a person does not fall over the railing, but at the same time feels comfortable when moving. The ladder can be considered safe only if all established standards are met.
The standard level of the railing in the outer area must be at least 120 cm. This dimension is specified in the special requirements of GOSTs. It also mentions the need for support posts and crossbars.
In accordance with GOST 25772-83 (clause 1.2, 1.3), the height of screen, lattice, combined internal fences should not be less than 900 mm.
The height of the railing, depending on the location areas
Open areas of increased danger are equipped with fences.
These include:
- Roofs of houses.
- Balconies.
- Interfloor dryers.
- Sidewalks along highways.
- Observation and sports grounds, etc.
Roof parapets at their low level are increased up to 60 cm from the roof surface. The extension is made with a stainless steel lattice fence.
In preschool institutions and schools, railings are made no lower than 1.2 m. The beginning of the measurement is made from the point of attachment of the vertical rack to the stairs. Here it is also recommended to mount intermediate crossbars for the smallest ones at a height of 0.6 m.
In private houses, emergency exits from the attic to the roof should be provided. Platforms and special bridges are installed here, which are also necessarily fenced. The level of continuous roof railings is at least 120 cm.
The sanitary norms of SNiP speak of the need to enclose all dangerous places in public office buildings. The height of the fences cannot be less than 120 cm. Since there is no provision for the presence of children, therefore there are no requirements for the installation of additional railings.
These standards provide for the installation of railings on the roof of the house more than 10 meters. Their material is stainless steel.
With differences in floor level equal to one meter or more, fences are also installed. Their height is regulated by 1.2 m.
Railing materials
These products should provide maximum safety and comfort when going up and down stairs. However, in addition to the basic functions, users impose additional requirements on their appearance. Enclosing structures are made from various raw materials, depending on the operating conditions and the design features of the environment.
Basic railing materials:
- natural wood;
- black carbon steel of ordinary quality;
- stainless steel - the most reasonable way to make the interior unforgettable;
- forged, cast elements;
- thick tempered glass panels;
- triplex;
- polycarbonate.
The choice of materials for the manufacture of fences is made in accordance with the interior design style of the premises or the exterior of the facades of buildings when installing railings on the street in the open air.
