Units of measurement of land area. How many acres in one hectare of land? How much is 15 acres of land in meters?

Sooner or later, owners of suburban areas think about fencing their territory and, accordingly, the need to draw up an estimate for construction. If you want to build a fence at your dacha with your own hands, then you should include in the estimate:

1. Cost of materials. To keep your budget minimal and your fence optimal, pay attention to the components and clarify their characteristics. If you want to save money and take thinner, smaller, used metal (especially used corrugated sheets), with the wrong degree of protection, or available material, all this will ultimately affect the beauty and strength of the fence. If you bought unfinished pillars, joists, or gates with a wicket, their production will add to the cost of the final product. Of course, today you can buy everything in Leroy Marlin necessary materials for the fence. But the metal and corrugated sheets in Leroy Merlin will most likely be quite thin, although cheap. But self-tapping screws, fittings for gates with a wicket and other small things necessary for installation will be expensive. Additional factors influencing the cost of the fence include the presence of wickets and gates, double-sided covering of the sheet, canopy, forging and any other decorative elements, as well as a small supply of material. If we are talking about the need to fence the area with corrugated sheeting and invest in the minimum possible amount, also think about the need for roofing screws, decorative strips on top, mortise locks and some non-standard fittings for gates with a wicket. The fence does not tolerate any excesses to a minimum, so think about the need for concrete work.
2. Cost of loading, delivery and unloading to the fence installation site. This important point, which many people forget about when they want to build a cheap fence with their own hands. You will rarely be able to save money here, and even vice versa, because you will most likely order all the components from different places. And if you order from a metal warehouse profile pipes, they are usually six meters long, so cutting them should also be included in the budget.
3. Cost of work to prepare the site for installation. Nothing should interfere with the construction of the fence: old fencing, bushes, trees, high grass, embankments, unnecessary things - along the installation line you must have working space about a meter on each side. Of course, you can do this work yourself.
4. Installation cost. It all depends on the complexity of installation: the number of logs, the pitch of installing the pillars, the method of installation (in concrete or not), the number of gates and gates, whether all components of the fence are ready for installation, whether anything interferes with the installation (soil, buildings along the fence line, neighbors and other). Pay attention to your soil; if it is compacted clay, bulk earth mixed with stones or other heavy soil, then it is unlikely that you will be able to drill through it with a regular gas drill and you will have to resort to additional costs for plugging pipes. And then you won’t be able to put up a fence for your dacha with your own hands cheaply. Standard installation of fences made of corrugated sheets, the price for work per 1 meter will cost from 300 rubles. But fencing companies rarely offer work without material, so installing a fence from corrugated sheets at shabashniks will cost from 70% of the cost of the material.
5. Associated costs: electricity, gasoline, paint, electrodes, bits, cutting discs, screws and, most importantly, your nerves.

Let's calculate the approximate budget for a standard fence made of corrugated board for 6 acres. The configuration of the plots may be different, but most often 6 acres is 30 m by 20 m (600 sq.m.), the perimeter will be 100 linear meters. For example:

• a fence of 8 acres is approximately 20 m by 40 m - 120 linear meters. m;
• a fence of 10 acres is approximately 25 m by 40 m - 130 linear meters;
• fences of 15 acres are approximately 30 m by 50 m - 160 lm.
• SNT fences are most often more than 300 linear meters.

To install an inexpensive fence 100 meters long with a gate and a wicket without a foundation, 2 meters high, on 2 logs, we will need 38 posts (metal profile pipe 60x60 mm, wall thickness 2 mm, length 3 meters), 64 logs (metal profile pipe 40x20 mm, wall thickness 1.5 mm, length 3 meters), 87 sheets of C8 corrugated sheets (thickness 0.5 mm), standard gates with a wicket, add to this the costs of screws, bits, cutting discs, paint, electricity, electrodes, covers for poles material, delivery and installation.

Approximate cost of a standard corrugated fence for April 2019 on our own in the Moscow region will be about 210,000 rubles. If you use an online real price calculator, the cost of material and installation will be: 120,000 plus 3,000 rubles delivery.

• a 20-meter fence made of corrugated sheets with gates and a wicket will cost 32,000 rubles;
• fence 50 meters made of corrugated board without entrance group- 59,000 rubles, every subsequent 10 meters + 11,800 rubles.

Our company “Fence at the House” works at minimal prices due to coordinated processing on own production large supplies of rolled metal, a well-structured scheme of working with customers and a professional installation cycle on site. We can offer the most competitive price for all our products and therefore we install a lot of garden fences. Thus, if you order a standard fence made of corrugated board from our company, it will be profitable. But you can really save money on a measurer, a bar, roofing screws, double-sided covering of corrugated board. A significant help to the budget is to order a fence together with your neighbors, but you should take into account the fact that during a joint installation, disagreements may arise regarding the choice of material, color and height.

In the life of each of us, various legal issues may arise, for example, we can enter into a purchase and sale agreement land plot or lease agreement.

First of all, any person will be interested in how much square meters in one hundred square meters and how to calculate it correctly. Let's talk about this in more detail.

How to calculate - using a specific example

A weave is a square with a length and width of 10 meters, i.e. 10 meters * 10 meters = 100 m2 = 1 weave. In practice, this is approximately 12-14 human adult steps. Using the same analogy, you can calculate a hectare: 100 square meters = 0.01 hectares = 0.02471 acres.

Example: A plot of 9 acres - this means a plot of 30 by 30 meters, or 20 by 45 meters, or 25 by 36 meters.

Origin of the word "weave"

The word “weave” comes from the concept of one hundredth of something. In this case, this is one hundredth of one hectare; in the example, it would look like this: 0.01 hectares.

Now on our land the entire area is measured in hundreds. And not only the land is measured. The following example can be used: a tractor driver needs to process 30-35 acres per day.

Why are calculations needed?

Thanks to these calculations, you can find out the size of your house or garden. The cost of the plot in the transaction will depend on the amount of land. Knowing the size of the plot's land in acres, you can plan the development of other buildings on your land.

Abroad, it is customary to measure land using other measures. Before entering metric system Old Russian measurements were used in Rus'. Previously, land was measured in tithes, and a hectare included twelve such tithes.

Yes, and on our land they began to measure land in hectares and acres not so long ago. This happened from the beginning of the October Revolution and the formation of the Soviet Socialist Republic.

But even in our time, not all countries measure land in hundreds. And in the territories that were under power Ottoman Empire the land is measured by Dunam. In Thailand, the measure of earth is called paradise.

The conclusion can be drawn as follows: one hundred square meters is one hundred square meters. The concept of “weave” is quite convenient; it arose about 100 years ago and its main property is the measurement of land.

The value is quite convenient and simple, does not require complex calculations. This calculation can be performed by anyone. It is enough to take a certain number of steps and you will see the allocated area.

Installation craze beautiful fences in Russia it is dictated not only by fashion trends. With a competent approach to the process, fences can be installed on plots of 6, 8, 10, 12, 15 or 20 acres for a very reasonable amount.

And if a high-quality product is available to the majority of consumers, then its fate is determined - it will become popular.

The information in this article will help you understand the principles of calculations and production of fencing for urban and summer cottages. Having understood how much fence you need for 8 acres or another standard area of ​​land, you can choose and install the fence according to the most favorable price, saving, as they say, wisely.

How to calculate the length of a fence?

First, let us recall that one hundred square meters is a square of land with a side length of 10 meters. Thus:

• area of ​​1 hundred square meters - S = 10 x 10 = 100 m²;
• plot area of ​​10 acres - S = 100 x 10 = 1000 m².

To install a fence on 10 acres, you need to calculate the perimeter of the site. As we remember from the school curriculum, perimeter is the sum of the lengths of the sides of a figure. For example, for an allotment rectangular shape with sides of 20 and 50 meters, the perimeter will be calculated as follows:

• P = (20 + 50) x 2 = 140 meters.

Thus, a fence of 10 acres will have a length of 140 meters, provided that the site is completely covered. By analogy, the length of a fence of 6 acres can be calculated, as well as for other formats.

Technology for calculating materials for fences

There are also no big difficulties here and even, according to experts, you can do without drawings. It is enough to remember a few important nuances:

• main support pillars installed in each corner + along the edges of the gate and wicket openings;
• the number of auxiliary supports depends on the estimated width of the covering material;
• The height of the fence directly affects its cost.

As an example, let’s try to find out how many meters of fence per 10 acres will be needed, provided that the profiled sheet marked C8 is chosen as the flooring, and the support posts are made from a 60x60 mm profile pipe. Let's say we have a plot of 30 x 33 with a total area of ​​990 m² (almost 10 acres). We divide the length of each side of the site by the width of the profiled sheet (for example, 1.15 m) - we get 107 pieces.

If the supports are brick, the number of metal profiles will decrease due to the thickness of the pillars. We will consider the gate and wicket as a separate side using solid sheets metal coating. If the number turns out to be a fraction, then round it to big side- so as not to get a hole in the fence.

We calculate the footage of the log based on the length of the profile and the design quantity (3 m each). Simple math also works here. We divide the total footage by 3, rounding up and multiply by the number of joists used in the fence (usually 2 or 3 rows).

In total, the calculation showed that for the simplest fence made of corrugated sheets and metal supports, we will need 107 sheets of corrugated steel, 246 meters of thin pipe for making logs. The number of main and auxiliary supports, provided they are spaced every 2.5 meters, is 49.

Next, we place a table that gives the basic calculations for the manufacture of fences in the MASTEROVIT company. Here you can clearly determine how much a fence of 10 acres costs for a house within the city or a fence of 6.8 acres (a standard summer cottage).

Non-standard plot shapes

What to do if the landscape of your site is uneven or the area has the shape of an irregular polygon? The easiest way is to seek help from a specialist. Managers of our company will help you calculate for free the approximate cost of a fence for 12, 15, 20 acres (or any other area), while at the same time giving advice on choosing materials taking into account the characteristics of the area.

The portfolio of the MASTEROVIT company contains photos of projects with an exclusive design created for a specific request.

Photo No. 2: Finished fence plot of 12 acres

The main factors in determining the final fence price

The cost of fencing is primarily affected by:

• costs of materials (concrete, brick, rolled metal, pipe, profile, accessories);
• fence dimensions (length and height);
• installation method (presence of a foundation or spot pouring, type of supports, cost of installation services).

It is important to determine in advance whether it will be necessary to pour a foundation for the fence or whether you can only dig in supports and reinforce them with concrete. The owner of a plot in a forested area, marked for the first time, will not be able to place strong house and a fence until it levels the landscape. All these aspects “come to the surface” during a geodetic survey, which is recommended to precede any construction on the ground.

It is difficult for an amateur to take into account such a number of nuances. That's why for construction quality fence It’s really worth contacting specialized companies. Professionals will do everything correctly, using sophisticated technology, and will not conduct experiments on your site.

How to choose a quality fence manufacturer?

In addition to the well-known truth that preference should be given to experienced teams working in accordance with GOST standards, there is another simple secret. Once you have a rough estimate, estimate the cost levels for materials and services. If the work costs about the same as the materials or less, feel free to sign the contract - this is a good price.

By fencing the perimeter or boundary of our home, we strive to hide from prying eyes. Having secluded themselves on their property, many owners are so obsessed with the idea of ​​isolation from the outside world that they erect fences up to 5-6 meters in height. Such fences may disturb those living in the neighborhood. To avoid controversial situations in this regard, the current legislation establishes rules for the construction of fences, their height and location.

General criteria for what the height of the fence should be and how to calculate it

The presence of a fence, its height and material of manufacture are always determined by factors that create discomfort for the owner, which include:

1. Annoying glances from neighbors. Home ownership is not always bordered by friendly residents.
2. Potential intrusion hazard. High fence will become a reliable natural barrier for persons plotting to steal your property. For this purpose, fences made of profiled sheets have become a popular option. When the thickness of the material is small, the upper edge of the fence is sharp, which does not allow you to lean on it. In its turn smooth surface sheets, further complicates penetration into your territory.
3. Neighborhood animals. This is especially noticeable in rural areas, where even chickens are able to fly over a fence up to 2 m high. If there is no fence in such an area, animals that have entered your garden can destroy the entire crop.

With so many reasons, the question arises: why? high fences don't meet often? It should be noted that this is due to the following factors:

1. The main one is the cost of materials for construction. It is not difficult to calculate that the construction of a three-meter fence will cost the same as the construction of two half-meter ones.
2. The higher the fence, the more its wind load increases. To withstand the pressure of strong winds, it is necessary to install a capital foundation and strong pillars, which means additional costs.
3. A high fence height will create discomfort for your neighbors. Such a fence will create a large shadow, which will negatively affect growth green spaces. This will also cause shading of the rooms in the neighbor’s house.
4. Limitations established by law.

The established requirements for the construction of fences require us to:

1. If the construction of fencing is carried out on the main highways of cities and villages, then the material for its construction must necessarily be agreed upon with local authorities.
2. The height of the fence dividing a street or public area from your site should not exceed 220 cm from ground level.
3. The material should not injure passersby. Care must be taken to ensure that its surface does not contain burrs, skids or sharp protruding fragments. Building a fence from unpolished boards and decorating it with barbed wire will be overkill.
4. The fence separating neighboring territories should also not exceed a height of 2 m 20 cm, but there are certain nuances:

• by agreement of the neighbors, a fence of raspberry, currant, bindweed, and ivy plants is allowed. However, the height of this living barrier should not exceed 150 cm;
• You need to install a fence that has a lattice appearance. Fences made of boards, gratings and nets are suitable for this, the clearance area of ​​which is at least 50%;
• if you are planning to build a blind fence ( brickwork, prefabricated or monolithic concrete slab, profiled material), then without the consent of the neighbors, it cannot be higher than 75 cm;
• written permission from a neighbor will be required if you build a fence whose thickness exceeds 5 cm. Without it, with such parameters, you can build a fence within your territory;
• When installing a fence made of brick, concrete and other materials that form continuous sections, you need to take care of the construction drainage systems and drainage systems. If rain or melt water causes flooding of a neighboring territory, then its residents have the right to file a lawsuit for the dismantling or demolition of the structure you erected;
• When building a fence on your own, you need to understand that its poor-quality installation will irritate your neighbors, who will turn into enemies. It’s unpleasant when there is a continuous shadow from the fence in the windows all day long or when the plants in the area wither for the same reason.

When calculating the height of fences, the material used for posts and sections should be taken into account.

If the fence is made of chain-link mesh, its height can be made more than two meters using profile pipes driven into the ground. The windage of such a fence is so small that you can ignore this moment.

If a continuous fence is erected, for example, from profiled sheets, then the impact of even a gentle wind can deform the entire structure. To avoid this, you will need to lay a columnar or columnar-tape base.

When building fences made of stone or brick, you will also need reliable foundation, as well as strengthening the pillars. As such they are used vertically installed pipes with a treated surface, which are pre-concreted at the base.

Considering all of the above, it should be borne in mind that building codes and regulations are not mandatory, but rather advisory in nature.

Only local legislation can enforce it. The height standards for fences specified in regional regulations may differ from those recommended building codes . This is due to the fact that in different regions of our country the sun has different angles elevation above the horizon. Differences are also taken into account constant speeds

The height of the fence is not always limited by standards. For example, in preschool institutions it must be at least 160 cm, and in schools additional bushes or other plants are planted in front of them.

Linear meter - what is it and how to determine it

To carry out measurements of the means used, repair and construction processes, they use not an ordinary meter, but special unit- running. It is often used to calculate required quantity material for a fence being built.

This unit of measurement facilitates the calculation process and implies the calculation of only the length of the material, since its width is standard size. It follows from this that this method is used to calculate the material in roll form.

A linear meter is 100 cm. Large quantities building materials have tags indicating the linear value. However, you can also find them with a note about the price per area. In this case, not only the length, but also the width is taken into account. A plot of 1 m² consists of sides, each measuring 1 m.

How to count a fence depending on the number of acres of land (5, 7, 9, 11, 20, etc.), examples

Before making calculations, you should determine what kind of value a hundredth is. From a school mathematics course it is known that the area of ​​1 hundred square meters (ar) is 10 10 = 100 m², respectively, the area of ​​a plot of 10 hundred square meters = 100 10 = 1000 m².

It should be noted that it is impossible to calculate the length of the sides using only area parameters. Each owner of a land plot has documents indicating the size of the property. Therefore, a plot of 5 acres (500 m²) can have dimensions, for example: 10x50 m; 20x25 m; 5x100 m; 15x33.3 (499.5 m²), etc. Each of the given dimensions is equal to or close to the indicated area. It follows that the multiplied values ​​of each example will be equal to or close to 500 m². For example: 10·50= 500; 20·25=500; 5·100=500; 15·33.3=499.5. You need to understand that plots are not perfectly square, rectangular or other regular shapes. To determine the length of the sides, you need to add the length and width, and then multiply the resulting value by 2.

It is important to understand this pattern: with the same area of ​​the figure, the values ​​of the perimeters with different side sizes will differ.

This fact can be easily verified using a clear example. So, imagine that a plot of land equal to 4 acres looks like four identical cells forming a square. In the image we can see 8 outer sides of the cells. If we imagine that four cells will be located horizontally, then the area of ​​​​the figure will not change, and there will be the same 4 acres. However, if you look closely, in this case we will see not 8 external sides, but 10. This a clear example explains the difference in the perimeters of a figure with the same area.

Let's substitute the existing parameters: (10+50)·2=120 m - this is the total length of the fence on a site with side dimensions of 10x50x10x50 m. Accordingly: (20+25)·2=90 m; (5+100)·2=210 m; (15+33.3) 2=499.5 m.

The same principle is used to calculate fences for areas with other sizes. For example, a territory with an area of ​​7 acres (700 m²) will have side dimensions: 26.5x26.4 m (699.6 m²); 20x30 m; 10x60 m; 6x100 m, etc. Let's make the calculation: (26.5+26.4)·2=105.8 m; (20+30)·2=100 m; (10+60)·2=140 m; (6+100)·2=112 m.

A plot of 9 acres (900 m²) can have the following dimensions: 30x30 m; 10x90 m; 40x22.5 m; 15x60 m, etc. We make the calculation: (30+30)·2=120 m; (10+90)·2=200 m; (40+22.5)·2=125 m; (15+60)·2=150 m.

An area of ​​11 acres (110 m²) can have the following dimensions: 50x20.2; 10x110m; 30x3.7 (111m²). We calculate: (50+20.2)·2=140.4 m; (10+110)·2=140 m; (30+3.7) 2=67.4 m.

An area equal to 20 acres (2000 m²) can contain plots of the following sizes: 10x200m; 5x400m; 40x50m; 70x28.6 (2002 m²). Let's do the calculation: (10+200)·2=420 m; (5+400)·2=810 m; (40+50)·2=180 m; (70+28.6) 2=197.2 m.

A plot of land equal to 27 acres (2700 m²) can have the following dimensions: 130x20.8 m; 10x270 m; 70x38.6 (2702 m). We make the calculation: (130+20.8)·2=301.6 m; (10+270)·2=560 m; (70+38.6) 2=217.2 m.

How to calculate the material for a fence (with specific examples)

To understand how in practice the required material is calculated by linear meters, it is better to consider this with an example. Our task is to determine how much material is needed to make a solid fence. First you need to determine the total length of the sides of the future building. Let's assume that the proposed area on which the fence will be installed has dimensions of 20x50 m. Since the area is rectangular in shape, you need to add these values ​​and multiply the result by half: (50+20) 2= 140 - the sum of the lengths of all sides of the rectangle or the total fence length. As a result of mathematical calculations, it was found that it occupies an area equal to 10 acres or 100 m².

For further calculations, you will need the parameters of each type of material, as well as dimensions and design future design. As an example, calculations will be made of materials for a fence made of: bricks, picket fences, boards and metal profile sheets.

Brick

To calculate the number of bricks for this fence, you need information not only on the width and height of the spans, but also the parameters of the pillars, since they will be built from the same material.

For example, the fence will be built of red brick with dimensions of 250x120x65 cm. The total length of the fence is 140 m.

The fence will have a basement level consisting of four rows of bricks. The basement part, located under two pillars and one span, contains 216 bricks. Base length - 4315 mm.

One of the similar layers of masonry for each pillar consists of five bricks. The height of the pillar and span located on the base part is 1625 mm, which is 25 rows. The width of the pillar on the front side is 500 mm.

The span width of the fence is 3500 mm. The laying will be carried out to the width of one brick in 14 rows.

The available parameters are enough to make a calculation and find out how many bricks are needed to build the entire fence.

Let's start with the calculations. First of all, you need to determine how many bricks are needed for the base of the entire fence:

To do this, you need to divide its total length by the length of the brick: 14000:25 = 560 bricks will be required for one row along the entire length. Since the base part consists of masonry three bricks wide and 4 rows high, then: 560·3·4=6720 bricks will be required for the base of the entire fence.

Now we calculate the number of posts for the entire fence. To do this, you need to subtract the distance between the middles of two pillars from the total length of the fence: 14000:400 = 35 spans and, accordingly, 36 pillars. It should be taken into account that there will be one more pillar, since the span on both sides is reinforced with a brick support.

Now you need to determine the number of bricks in one pillar. To do this, you need to multiply their number in one row by 25 rows: 5·25=125 pieces. We multiply the resulting value by the number of all pillars: 125·36=4500 bricks will be required to construct all the fence posts.

We calculate the amount of material for spans brick fence. We know that the height of the span contains 25 rows, and each of them contains 14 bricks. We make a calculation by multiplying these values: 25·14=350 bricks are needed to lay one span of the fence. We multiply this result by the total number of spans: 350·35=12250 bricks.

Profiled sheets

Sheets of profiled metal with the same height and width equal to 200x100 cm were chosen as the main material for the fencing.

It is easy to calculate the amount of profiled material for a fence 140 m long. This requires 140 sheets. This simple calculation is acceptable for a continuous fence made of such material. If the fence design includes protruding supports or other elements, these nuances should be taken into account, since the width of the spans will be reduced. Accordingly, less profiled metal will be required.

Concrete for foundation

Concrete is most often used for the base of the fence. The shape of the foundation has its own characteristics, and resembles several connected geometric shapes, such as: cylinder, cube and cuboid. This form of foundation implies a strip-column base for fencing made of heavy materials. To do exact calculations the required amount of concrete, you need to remember the school geometry course, namely the formulas for the volumes of these figures. For convenience, calculations will be performed for each figure separately.

To find out the volume of concrete for a columnar base, you need to apply the formula for calculating the volume of a cylinder, which looks like this: V=πR²h, where π is a mathematical quantity geometric number equal to 3.14; R is the radius of the cylinder base; h is the height of the cylinder. Optimal sizes for such a foundation are shown in the image.

Let's substitute the values: 3.14∙0.125²∙0.5=0.39m³ the mixture required for one concrete pile.

Now we will do the calculation for a cubic foundation located under the pillars. To do this, you need to use the formula for calculating the volume of a cube, in which the length - L, height - H, width - S are multiplied: V=L∙H∙S. Let's substitute the values: 0.3∙0.3∙0.3=0.027m³ - concrete is needed for one base under the pillar.

Now you need to add up the obtained values ​​to find out how much mixture is needed for a foundation fragment consisting of the previously described figures: 0.39+0.027+0.129=0.456 m³

By making these simple calculations you will get the exact parameters of the future foundation. To find out how much concrete is needed for the entire fence, you need to multiply the resulting value by the number of pillars in the entire fence structure.

It should be taken into account that the number of spans will be one less than the number of pillars. Previously, we established that a fence whose length is 140 m will have 35 spans and 36 posts. Now it is easy to calculate the total volume of concrete required to install the foundation of the entire fence. For this: 0.456∙36=16.415 m³, but since the number of spans is one less, it is necessary to subtract the volume parameters for one span from this figure: 16.415–0.129=16.286 m³ of concrete will be required to pour a strip-column base for the entire fence.

Foundation reinforcement To strengthen the base of the fence use reinforcing bars . Before pouring the foundation, this material is used to make metal structure V as four

longitudinal rods and transverse elements (clamps) for the base tape, and four rods for its pillars.

As we already know, a fence 140 m long will have 36 pillars with 35 spans. The distance from the beginning of one pillar base to the end of the second is 300 cm. The distance between the transverse elements of the structure is 80 cm. The height and width of the clamps are 25 cm each. Their number for one span is 4 pieces. Using this data it is easy to calculate the amount of reinforcement. First you need to set how many meters metal rods

required for one pillar and span.

• For a single span tape:
• 300∙4=1200 cm - longitudinal rods;
• 25∙4∙4=400 cm - transverse elements;
• 50∙4=200 cm - rods for a concrete pillar;

Now it’s easy to calculate how many metal rods are needed for the entire fence. To do this, you need to multiply the resulting value by the number of sections of the entire fence. As we already know, there are 35 of them, therefore: 18∙35=630 m of material will be required to reinforce the foundation for the fence.

Fence

The amount of material required for picket fences depends on the width of the material, the distance between the boards, the way they are positioned, and, accordingly, the length of the fence itself.

It should be taken into account that when installing a picket fence, the distance between its elements can be different. However, a fence in which the gap between the pickets will not exceed their width will look more aesthetically pleasing.

The width of the picket fence may vary depending on individual order consumer. If we are talking about a European picket fence, then in this case there are standards. The width of this material can range from 70 to 170 mm.

To calculate the number of pickets for a fence, you need to use the following formula: K=A/(A1+B) where A is the length of the entire fence, A1 is the width of the picket, B is the gap between the slats.

Let’s assume that the length of the fence is 140 m, the width of the pickets is 120 mm, and the gap between them is 80 mm, then according to the formula, the calculation of the amount of material will be expressed in the following example: K = 140 / (0.12 + 0.08) = 700 pieces .

You can always reduce costs for materials if you make the distance between the pickets a little larger, but within reasonable limits.

In the case where the fence provides for the arrangement of pickets on both sides in a checkerboard pattern, then the previously obtained result must be doubled.

Boards

The use of this material involves installing fence elements in a vertical or horizontal position. Just as in the case of a picket fence, the number of boards in a vertical position is calculated using the specified formula. When mounting horizontally, the length of the sections and the material itself, as well as the length of the fence, should be taken into account.

For fences I use unedged and edged boards.

In the first case, the material is not stripped of bark, has a length of about 600 cm, and a width of 100 to 500 mm. Such boards require additional processing and drying before use. Accordingly, such material has a low price, but it will take time to bring it to the proper condition.

Edged boards They are made with a width of 100 to 150 mm, a thickness ranging from 20 to 25 cm. This material does not require additional drying or sanding. The surface of such boards is smooth and can be made in the form of a semicircular profile. I use it to make boards noble breeds wood, such as oak or larch. Edged boards are an expensive ready-to-use material.

When calculating the material installed horizontally, the width and length of the board, as well as the length of the entire fence, are used. Let’s say the fence is 140 m long. The width of one section is 3 m, its height is 2.5 m, the distance between the boards will be 5 cm.

Using these parameters, you need to determine how many boards are needed for horizontal placement in one section. To do this, you need to add the width of one board with the provided distance between the wood, and then divide the height of the section by the resulting value: 2.5:(0.15+0.05)=2.5:0.2=12.5 pieces.

Then, to find out the total amount of material, you must first find out how many sections there will be in the fence. To do this, its length must be divided by the width of one section: 140:3 = 46.6 sections. Now we multiply this value by the number of boards in one section: 46.6∙12.5 = 582.5 boards will be required to erect a fence 140 m long, 2.5 m high, with gaps between boards equal to 5 cm.

Rivets and screws

To secure fence elements, rivets, nails or self-tapping screws are used. When installing a European picket fence, rivets are most often used, and for wood - nails and screws. By calculating the number of fence elements, it is easy to find out how much consumable material is required.

It should be noted that the required number of rivets, nails or screws depends on the number of installed logs, the method of fastening and the material of the fence.

If the fence consists of a European picket fence, then with two cross joists two rivets are enough. During installation wooden picket fence or boards with two lags, you will need 4 screws or nails - two for each crossbar.

Let's make a calculation for a fence 140 m long from a picket fence. As we know, such a fence will require 700 pickets. Since one picket fence on two lags will require 4 screws or nails, then: 700∙4=2800 pieces.

It should be taken into account that consumables You should always purchase with a reserve.

Carrying out accurate calculations when building a fence will ensure the reliability of its design and save you from unnecessary cash costs. Having learned to make these simple calculations, you will be able to give good advice how you can help your loved ones or neighbors.
