IN recent years sheet corrugated sheets have taken a leading position among the materials used for fencing.

Low price, easy installation and durability. These three factors are decisive when choosing it.

Stability and strength metal fence provided by pillars. They are the most critical element of the design.

If the pitch and depth of their installation are chosen incorrectly, or mistakes are made when attaching the sheathing, then the owner of the estate will soon have to deal with repairs.

In this article we will talk about what posts are needed for a corrugated fence and how to install them correctly. Having received useful information, you will avoid annoying mistakes and unnecessary waste of funds on restoration work.

Which posts are suitable for corrugated board fencing?

Strictly speaking, any. However, we are interested in a material that is as durable and strong as possible. Wood is the least suitable option. Its service life is much shorter than that of metal.

Having installed corrugated sheeting on pine racks treated with an antiseptic, you will have to remove it after 6 years and start work again. The use of larch or oak extends the life of the frame, but increases. That's why wooden racks Most often used for temporary fencing.

You can eliminate contact of wood with the ground by making a metal adapter and concrete it in the foundation. However, this option is not suitable for high fences experiencing intense wind loads. Another similar option is to use a piece of profile pipe as a steel sleeve into which the post is inserted and then concreted.

Next contender for the title supporting structure– asbestos cement pipes. They are inexpensive, do not rot and are quite durable. Their disadvantages include the fragility and complexity of fastening the purlins.

Asbestos-cement pipes should not be left open. Rainwater, having fallen into them like into a well, it will freeze in winter and tear the walls. Therefore, after installation they are filled cement mortar or before starting work, plugs are installed at both ends.

Reinforced concrete is also suitable for making posts. The only requirement that needs to be taken into account at the pouring stage is the installation of metal embedded plates to which the purlins will be attached.

The technology of industrial concrete casting has made great strides in recent years. Therefore, instead of labor-intensive “home crafts”, we recommend buying aesthetic prefabricated structures.

Metal is the undisputed leader in the field of fence construction. It goes well with corrugated sheets, withstands wind loads well and retains its strength for 50 years. The only thing that is required from the owner is to update the anti-corrosion protection once every 3-4 years.

The cross-sectional shapes of standard steel posts are circle, square and rectangle. A profiled pipe is more convenient to install and for this reason it is used more often than a round one.

Fastening the purlins can be done in different ways using welding, additional elements and threaded connections. This is another advantage of steel racks.

Fence posts made from corrugated sheets are often made of brick. However, even in this case it will not be possible to do without metal. It is required for the manufacture of embedded parts to which the logs are fixed, and to give the structure sufficient rigidity.

The basis is reinforcement bars or profile pipe. The space between the masonry and the metal is filled with mortar.

The disadvantages of brick racks include the high price, labor-intensive masonry and heavy weight, which requires pouring a solid foundation. In terms of aesthetics and durability, they are superior to other types of fence supports.

To install corrugated fencing, it is advantageous to use screw posts. These are hollow steel pipes of square or round profile, equipped with a wide blade.

Using them, you can assemble a strong frame without earthworks and concrete. The stand-pile is screwed into the ground to a depth of 0.8-1.2 meters and is firmly held in it due to the wide blades. On soft soil, screw posts can be placed manually using a special mechanism for gripping and rotating.

The main points of installation

In order to correctly install the pillars, it is necessary to choose the optimal method of fastening them in the ground. To do this, you should take into account the composition of the soil. If it is sandy and dense enough, then the racks can be installed without concreting in prepared wells or by driving.

The main danger for any fence supports is the forces of frost heaving, pushing them out of the ground and warping the frame. On sand that allows moisture to pass through well, the fence will not be deformed. In this case, concrete is used to increase the contact area of ​​the support with the ground.

On dense sandy soil, it is recommended to bury the posts by at least 1/3 of their length. On loose and heaving soil the embedment depth remains the same, but the well should be drilled with a diameter 100 mm larger than the width of the column and always below the depth of seasonal freezing of the soil.

Having done this work, the bottom of the hole is filled with crushed stone and sand up to the level of installation of the racks. After installing the support, a mixture of crushed stone and sand is poured around it layer by layer with compaction. By allowing water to pass through, it will protect the post from being pushed out by frozen soil.

Concreting can be done in one of two ways:

• Traditional (dig a hole, lower a support into it and fill it with concrete);
• Combined (a well is drilled to a depth of at least 80 cm, a stand is installed and a wide hole 40 cm deep is dug around it for concreting).

Note that the second option is more economical than the first in terms of concrete consumption, although it is more difficult to implement.

Fence posts can be connected together with a shallow-depth tape grillage. It increases the rigidity of the fence and improves its appearance.

For fence from steel pipes You can use different profile sections. Most often, supports are made from square pipe 60x60 mm with a wall thickness of 3 mm or rectangular 60x40 mm (wall 3 mm). Racks from round pipes less convenient when installing purlins. Therefore they are used less often.

The second issue that should be resolved before starting work is the distance (step) between the pillars. Profile pipes are supplied in the form of 6-meter lengths, so to reduce losses it is more profitable to cut them into 3-meter pieces.

The optimal cross-sectional size of the purlins (lag) is 40x20mm, wall thickness is at least 2 mm.

The distance between the logs depends on the height of the fence and ranges from 1.2 to 1.6 meters. A gap of 5 to 10 cm is left from the bottom of the sheet to the ground or to the top mark of the foundation grillage.

Installation of metal poles and frames

The first stage is marking the contour of the fence using a tape measure and cord. As this work progresses, pegs are driven into the ground to mark the locations for digging holes.

First, the pillars are placed, leveled and concreted at the corners of the site. After this, they dig holes for row racks. A cord is pulled between the outer supports and row posts are placed along it.

Attention! For corrosion protection bottom part the supports must be welded with a steel plate and coated with a protective compound. The top covers are welded to the racks after their installation is completed or special plastic plugs are placed in them.

Double control of distances during the installation process is necessary. When drilling and digging holes, there is a deviation from the intended installation points of the supports. Metal does not forgive mistakes, so the distances between the centers of the racks must be maintained with an accuracy of 1 cm.

Having placed the supports, they are temporarily secured with wedges or pieces of brick and the verticality and pitch are checked again. After this, you can pour concrete or fill the holes with a sand-crushed stone mixture.

After giving the concrete 7 days to gain strength, you can begin installing the joists (purlins). They are attached by welding or threaded connections. Welding technology is used more often because it is simpler and faster. Having leveled the run, grab it to the stand, check the “horizon” again and fix it with a working seam.

Having collected metal frame, you can start attaching corrugated sheeting to it using special self-tapping screws.

When installing a fence, we first decide what goal we are pursuing, other than to fence off a piece of land. What kind of fence do we need? For many who want to save at least a little, it is the best option price-quality.

For relative durability and low cost, it is more logical to install supports made of metal pipes. But do not forget that metal fence supports must be prepared for digging into the ground. Covered with primer and paint, anti-corrosion agent.

Calculation fence post distances calculated taking into account some parameters.

• Fence height
• support section
• fence length
• number of fence supports

If the fence and supports are made of brick. The distance between the metal supports inside each brick pillar will be 2.5 m.

If the supports are wooden, with a fence height of 2 meters, then the distance between the posts will also be 2.5 meters. Such columns need to be buried to a depth of 1.2 meters.

Before installation wooden fence the pillars are dried and processed copper sulfate and coated with primer or oil paint. Then we wrap the lower end of the fence with roofing felt. Such a pole is installed “top down”.

Modern technologies make it possible to build a fencing structure for a dacha or suburban area with your own hands and in a fairly short time. But in the process of carrying out work it is necessary to take into account many important characteristics. Therefore, let's talk in this article about what should be the distance between fence posts various types. After all, the strength and durability of the entire structure depends on this parameter.

Installation in the right way

The distance between two adjacent support columns of a fencing structure on a dacha or suburban area is the step with which these supports should be installed in the ground. However, it is important to clarify here next moment: This is not a universal setting. That is, for each individual type of fencing, experts recommend adhering to a certain value, measured in meters. Then the fence at your summer cottage, built by you yourself, will certainly please you with its durability and strength.

Let's talk in more detail about the different values ​​of this parameter in certain specific cases.

Chainlink mesh

Chain-link fences have become very common lately. This can be explained by the ease of installation of such a fence and its cost-effectiveness. To make the site more attractive, many summer residents plant vines next to it, which curl very beautifully over a metal mesh:

• Experts say that the most suitable width metal mesh For garden fence is 1.5 m. But if you want to make the structure taller, you can raise the top edge of the mesh to the height of your choice. And the lower part of the structure can be laid with any material at hand. For example, bricks or wooden boards are used for these purposes;

• If we talk about the required number of support posts for installing a product made from chain-link mesh, then this indicator is calculated based on the measured length of the fence and the selected distance between its supports. That is why it is important to clearly determine the optimal distance between the posts of a chain-link fence. Practice shows that to ensure the strength and reliability of the entire structure, this figure should be equal to 2.5 m.

Made of brick

People have been using bricks for many years in the process of building fences for country houses and suburban areas. Examples of such buildings are shown in the following photos. This trend is due to high performance qualities this material. Brick is valued for the following characteristics:

• high strength;
• durability;
• reliability;
• attractive appearance.

Brick columns are laid in the usual way using cement-sand mortar and mandatory ligation of stitches. If you undertake to do the masonry with your own hands, make sure that the support is horizontal and vertical. To make the product attractive, apply decorative stitching to the seams.

In the process of building a brick fence post, you need to install two embedded parts on all sides of the support into the masonry. This is done in order to subsequently be able to secure the spans, wickets and gates of the structure.

To determine the required height fence posts made of brick, you need to know the height of the structure. Typically it varies from 2 to 3 m. The distance between the support columns will depend on the width of the spans. However, experts do not recommend installing brick supports more often than every 2.5 - 3 m.

From corrugated sheets

The optimal material for creating structural pillars from corrugated sheets is a profiled metal pipe:

• If we talk about the distance between the support pillars in this case, qualified experts advise sticking to 2 - 2.5 m. Such span dimensions will give your fence required level rigidity and flexibility, but at the same time they will not allow it to break under the influence of strong gusts of wind;
• The length of the pillars will be determined by the size of the profiled sheet used, as well as the characteristics of the soil in your suburban or summer cottage.

Knowing the step with which you will install supports for a structure made of corrugated sheets, you can easily calculate required quantity supports

Made of wood

Wood is the most common material in country houses and suburban construction. It is highly environmentally friendly and available material, which explains its popularity.

When constructing a wooden fence, the distance between its supports is often chosen, which is 2 - 3 meters. Be sure to take into account the following fact: the higher your wooden structure is, and the wider its spans, the more securely you will need to fix its supports.

Logs or metal pipes of various shapes can be used as posts for such a fence.

From a picket fence

Let's talk separately about wooden picket fences. They are one of the most frequently erected types of similar structures in private construction. They delineate the boundaries summer cottage, but, at the same time, they do not at all shade the plants that grow next to them. This design of fencing looks very attractive.

You can give fences for a summer cottage, built from picket fences, any height, shape, color shade. The installation distances of the support pillars can be any. For these reasons, such designs have a very original and attractive appearance. Look at the following photo to see this.

Let's sum it up

The step with which the support pillars of fencing structures are installed is very important parameter, on which their strength, resistance to gusts of wind and other loads, durability and reliability will depend. This fact should not be neglected, otherwise your fence will not please you with a long service life.

The distance between fence posts is a variable parameter that fluctuates within certain limits. Its universal value between pillars is 2.5–3 m, but this is only a conditional indicator of the normal distance. A lot depends on the type of fence to which the fence belongs, on the purchased supports and the method in which installation will be carried out. In turn, the installation of fence posts is carried out at a distance depending on the type of soil, weather and climatic conditions, location of the fence on the terrain.

Distance between supports

The gap between the fence posts depends on several parameters, and two main ones are decisive - the type of fence that the developer intends to install on his territory, and the type of supports selected on the basis of the closest correspondence to this type. IN construction industry Many types have been developed, adapted for securing fences of various types.

Options for installing supports in the ground depend on the climatic features of the area

It depends on the material chosen by the developer to construct the demarcation between his own land ownership, neighboring or street area, and it depends which pillars become the subject of preference.

Ideally, calculating the distance between fence posts should be carried out by specialists. The requirements for supporting structures may be different for a beautiful fence made of wood.

Scheme of foundation arrangement and support calculations

The ideal option is considered to be those supports that combine versatility and the ability to use variable fastening methods. They must certainly be durable, with a guaranteed long service life.

If they don't require additional care, this is generally ideal. But the main criterion that is taken into account when choosing is affordability. In principle, almost all accepted types of poles are relatively affordable in cost.

Sometimes the main costs fall on the fastening methods: joists, fasteners, crossbars, corners, etc.

Installation option metal poles with profile cross beams

Types of supports

1. From metal, made from profile or pipe, ideal option to make a fence from chain-link or wall corrugated sheeting. Hardware there are different diameters and can be of variable shape around the perimeter of the section (for example, square or rectangular, and not just the usual round). The thicker the pipe, the more expensive it is and the more weight it can withstand. This is quite beneficial, but the more weighty the structure is attached to the pipe, the greater the cost of fastening strips, tips, plugs, hardware and headband. Optimal distance between corrugated fence posts, if metal supports are used, is calculated from the size of the section, its thickness, and climatic features. Long distance leads to the appearance of a sailing effect, and sections of the fence made of corrugated sheets are torn off even from the most durable fastening.
2. - traditional type of support structures. They are not very decorative, but they are durable and are not afraid of moisture or temperature changes. The modern construction industry has also developed ways to give them a more aesthetic appearance. A good owner has a simple concrete pillar can be improved by painting, decorative plaster, lined with tiles with variable patterns or textures. This material has many advantages over others, but it is preferred because of its guaranteed strength and lack of maintenance.
3. They prefer to install simple ones in areas with a humid climate, where a material is required that does not lose its properties under the influence of precipitation. Possibility to install stacked columns from structural elements led to a new round of popularity of old, tried and tested material.
4. Reinforced concrete pillars are biologically and chemically resistant, simple, affordable and technologically advanced. But they are used quite rarely in the construction of fence structures, since they have significant weight, and also do not have the most optimal ratio between weight and ability to withstand a payload.
5. Installing columns or posts is one of the most popular methods when constructing fences. Relative simplicity, cost-effectiveness and durability, a high degree of decorativeness, stylishness - all these are qualities inherent in brick supports, which is why they are preferred by a significant number of developers.
6. Screw posts with a cutting blade are a way to quickly and easily penetrate to the required depth. This is an excellent option for problematic soil, allowing you to make the structure durable without bothering too much with the foundation. As for the material of manufacture, this is most often a type of metal device for fastening sections.
7. The tendency to make supports from plastic is also dictated by practical considerations - sales ready-made structures for assembly, decorative component and resistance to climatic conditions. The presence of different color variations is an important criterion in the choice. However, there are no cheap polymer kits on sale, and many construction companies prefer not to do installation plastic structures, because they are not confident in their ability to withstand the payload. And this means indispensable concrete foundation and a whole system of additional fastening elements - anchor bolts, crossbars and crossbars.

To choose a particular variety, you also need to take into account several components. For example, what goes best with wooden pickets, and what goes with the same structural ones.

The choice of distance between supports depends on many factors

In the calculations carried out, the following components are certainly taken into account:

• the type of material chosen and methods of attaching it to the supporting pillars (strength and character, number of structural elements, section width, if it is homogeneous);
• the type and design, width and strength, as well as size are very important in purchased or manufactured supports;
• depth in and the method used, which is introduced and secured in the intended places;
• soil condition, presence of waste or groundwater, type of soil, presence of erosion, subsidence or swelling (each type has its own difficulties and features of working with fence supports);
• the weight of the structure, which should not exceed permissible limits, otherwise installing the fence makes no sense (it will collapse at the slightest load);
• availability of a site plan and cadastral markings, especially if a permanent fence is being built (this is extremely necessary if the site is of irregular shape);
• the accuracy of the measurements taken and the verification of the calculations made when marking for digging holes (otherwise the standard sections may not fit);
• a distance dictated by strength indicators and carefully verified using proportions (you can calculate the depth for the underground part as follows: – 1/3 of the entire height of the fence);
• the fence will rise to standard height or the construction of a more grandiose one is planned.

Required ratios of the height of the pillar and the depth of the excavation for it

It will take more time, but will save some money. The depth depends on the type of soil, the weight of the base material and the climate in the area. But the depth of the concrete strip does not affect the post holes.

When calculating the required depth of supports, three parameters are taken into account:

• expected height level (it is calculated using a standard formula or taking into account the pressure of the solid weight of the building material);
• the soil freezing limit (little attention is paid to it in warm regions, but in areas with a temperate or cold climate the soil can swell, and the water in the soil freezes and exerts pressure from below);
• an increase for stability (about 30 cm) is made for any type of construction; this is a precautionary measure that allows you to achieve the reliability of any structure.

Table of soil freezing depth values ​​depending on the city

Of course, a lot depends on the method in which the fastening will be done. Will it be simple driving into the ground, combined installation, butting or full concreting. Each of these methods is chosen based on certain considerations. Metal posts are almost always installed; they are the best option for a chain-link fence.

Metal posts for chain-link fencing

The lightness of this material does not require special precautions.

But if you plan to work with heavy corrugated sheets, reliability is required not only in burying and securing the pillars, but also in the number of transverse joists and the quality of the fasteners used.

Scheme for determining the length between supports subject to certain conditions

Such figures are determined by practical experience, and in some types of building materials for fencing, sections are sold with an already defined ratio, plus the allowance required for installation. For any material, the distance cannot be more than 3 meters. This also applies to a fence made of picket fences and even an extremely easy-to-install and lightweight fence made of welded mesh.

For a fence made of corrugated sheets (profiled sheets)

The distance between supporting structures when working with should not exceed 2–2.5 m. This is a parameter that has been tested in practice, and its violation has resulted in disastrous consequences for some would-be builders.

Sketch for calculating the length between supports for fences made of profiled sheets

An attempt to save on installing supports led to the creation of a sailing effect, which in any climatic conditions can develop even in relatively light winds due to the characteristics of the metal profile.

With metal stands

Construction of a fence foundation with metal supports

You can navigate the required distance even using standard ones, which does not exceed 2.5 m, even taking into account additional allowance.

With brick pillars

The distance between brick pillars for corrugated sheets can be 2.5 m, because there is also a foundation.

Installation diagram of a fence with brick supports

With this fastening, the necessary stiffening rib is created and the flexibility inherent in a convenient and practical building material is preserved.

For chain link fencing

Installation mesh fence must comply with the following parameters - no more than 36 m between corner pillars and no more than 2.5 m between adjacent ones.

Mesh fence installation plan

The number of pillars between the corner stops is calculated precisely from the permissible distance of 250 cm. Otherwise, the structure will become fragile and will soon collapse.

For a fence made of Euro picket fence (metal picket fence)

Normal distancing supporting elements standard – 2.5 m. But there is one nuance that must be taken into account.

The procedure for constructing a barrier from metal picket fence

When installed overlapping, flush or checkerboard, the calculated weight of a metal picket fence increases. And if it is not mounted on a foundation with brick columns, it is better to shorten the inter-pillar spacing a little.

For a wooden fence

They prefer to install a wooden fence with supports also made of wood. Cheap and practical material belongs to the category of unstable, and purchasing more expensive supports simply does not make sense. more durable, they can serve for many types of mounted fences.

The procedure for assembling a wooden fence

However, for each type, the distance between the pillars must be selected taking into account the size of the section and the degree of load to withstand. An important role in determining what distance is optimal is played by the degree of depth of the supporting structures and the method by which they are secured.

The use of wood involves periodic surface treatment

And it, in turn, depends on the terrain, soil type, climatic conditions and the type of pillars used by the developer for installation.

What is the distance between the posts of a fence made of corrugated sheets - this question worries many when installing a fence made of corrugated sheets. Many of us will go to Yandex and ask the all-knowing search engine. Without any doubt, he will give you a quick answer - 3 meters. But is everything so obvious? As you may have guessed, not at all.

Let's look at the distance between the pillars. Firstly, the pillars can be different:

• brick pillars;
• metal pillars, overlapping logs;
• metal poles, butt joists.

Secondly, the profiled sheet can also be different. The total width of the C8 corrugated sheet is 1200 mm, the working width of the C8 corrugated sheet is 1150 mm. For corrugated sheets C10 and C20 the same parameters: 1150 mm and 1100 mm.

Now let's try our profiled sheet on 3 types of pillars.

1. Brick pillars. The corrugated sheeting on the fence must have a minimum overlap width. The overlap width corresponds to the difference between the normal and working width, that is, 0.05 m. Now we need to decide how many sheets we will place. If there are 2 sheets, then the width of the C8 sheets = 1.20 + 1.15 = 2.35 m. If there are 3 sheets, then 1.2 + 1.15 + 1.15 = 3.5 m. 3.5 m is extremely an unpleasant distance from a sailing point of view. Therefore, the distance between brick pillars with C8 sheet is 2.35 meters.
   Let's make calculations for profiled sheets C10 and C20. 2 sheets: 1.15+1.1=2.25 m. 3 sheets: 1.15+1.1+1.1=3.35 m. If the fence is high and it is possible to install 3 logs, then it is better to take the distance 3.35 meters using 3 sheets. If the fence is low, 3.35 meters between brick posts will look bad, so opt for two sheets and a distance of 2.25 meters.
   But there is another side to the issue - economic. Laying fence posts is not cheap. Therefore, from the point of view of investing money, it is better to use a layout with a minimum number of brick pillars.
2. Metal pillars, overlapping logs. No problem here. It is optimal to use a distance of 3 meters along the axes of the pillars. But an important condition is the lag material. If the pipe is 40*20*2, then 3 meters is possible, if 40*20*1.5, it is better to take a shorter distance.
3. Metal poles, butt joists. Calculations for brick pillars are also relevant here with the only amendment that the installation of metal pillars is not as expensive as brick ones. If you use 3 logs and pillars 80*80, then with C8 corrugated sheets make 3.5 meters between the posts, and with C10 and C20 corrugated sheets - 3.35 meters.

But for all calculations there is a significant catch: standard cutting profile pipes- 6 meters. Six times 2 and 3. If it is possible to increase the logs to the required lengths, no problem. But if the supplier of materials for your fence refuses to make logs of the required length, then you will have to be content with the usual distance between fence posts of 3 meters, which is customary for many.

That's a lot different meanings we did it. We hope they will help you with self-installation corrugated fence.
