Production of mesh Chain-link: material characteristics + areas of application + required equipment + 3 reliable machines + manufacturing technology + 6 sales channels + methods of implementation + calculation of profitability.
On the building materials market, you can find consumer goods, which, regardless of the passage of time, continue to be in high demand. Among these is the Rabitz grid.
It is in demand even regardless of seasonality. For its manufacture, large investments are not required, the equipment is oversized, and the products themselves are stored in rolls, which eliminates the need to rent large areas.
All this allows us to start production of chain-link mesh and successfully develop it in the future. Let's consider the main points of this business.
Chain-link characteristic
The Rabitsa grid began to be operated back in the 70-80s. XIX century. There are many speculations regarding its inventor. Most likely, the world owes the appearance of this object to K. Rabitz, after whom the material is named. He also patented this creation.
The chain-link is rightfully called a universal structural material. Low-carbon steel wire is used as a raw material. At the same time, for the production of products, the use of galvanized solid wire or metal with a polymer coating (PVC) is noted.
Occasionally, the production of the chain-link mesh is carried out on the basis of aluminum and stainless steel wire. In this case, the wire material should have a thickness in the range of 1.5-5 mm.
The product is produced in various braided shapes: rhomboid (the diameter of each rhombus is from 5 to 20 mm), square (d = 10-100 mm). Typically, each mesh cell can be 3-100 mm.
The finished product is delivered to the buyer in rolls, the length of which does not exceed 10 m, the height is about 1.5 m. Some people order a chain-link mesh of non-standard dimensions. Then its linear size in the longitudinal direction is 15-18 m, and the height of the mesh reaches 1-4 m.
This attribute of construction works can be rolled in different directions (clockwise and counterclockwise). And in no case should you combine rolls with excellent spiral twisting.
The raw materials used in production leave their mark on the properties of the Chain-link. So, the mesh made of galvanized steel, previously heat-treated, has greater strength.
Also, the strength of the material is significantly influenced by the diameter of the wire and the size of the cells themselves. If you are engaged in the production of a chain-link mesh with a large diameter, but the mesh size is reduced, a lot of metal will be required, and therefore at the exit it will be very strong. The opposite situation is when the cells are increased, and the wire diameter is used reduced. This leads to a decrease in strength.
It is better not to skimp on raw materials in the production of mesh, because experienced buyers have learned to bring unscrupulous entrepreneurs to the surface. It is enough to put a Rabitz roll on the scales, divide the resulting value by the number of square meters in order to find out the weight of one and compare it with the theoretical one.
When the difference exceeds 5%, the quality of the material is not top notch. This means that the manufacturer cheated in the length of the mesh or the width. Weakness of the cells is characteristic of such a product.
When the chain-link is made of polymer wire, the result of the production is a material with a long service life. In addition, its production can be carried out in any color.
The PVC mesh is protected against corrosion. Hot-dip galvanizing helps to make it resistant to rust. When producing such a chain-link mesh, you will provide your potential customers with a wear-resistant product that will not be afraid of rust for 25 years.
It is important that the zinc content in the mesh is varied from 70 to 90 g / sq. m.
Why do you need the production of chain-link: areas of application of the mesh
The chain-link mesh is produced for different purposes. Humanity has found application for it in the most diverse spheres of its life.
- For example, the chain-link is widely used for the construction of fences.
- It can also be used as a sieve for sieving bulk solids.
- In mines, when extracting coal and other useful natural resources, the chain-link mesh serves as a fastener for mine workings, as a material for thermal insulation work.
- From the chain-link they make aviaries for dogs, bird cages.
- In construction, the result of such production is necessary for plastering.
- When patching asphalt, they also resort to using a mesh that strengthens the canvas.
- Ventilation openings are sealed with a chain-link, with its help, heating mains and reinforced concrete structures are reinforced.
In addition, the strip foundation device is not complete without this mesh.
- The production of Chain-link is profitable in the horticultural industry. Often sports facilities and water bodies are fenced with it.
What is needed to organize the production of a chain-link mesh?
Even before the stage of formation of the production of any product, initially an entrepreneur independently or involving economists, marketers assesses the demand for a product, the needs of the market.
What is the profitability of the chain-link mesh production?
Let's calculate the income / expenditure side. For example, let's take a mesh (the cells are 55 * 55 mm in size), in the production of which we used a wire made of galvanized steel with a thickness of 1.6 mm.
To find out the cost of a unit of production, you need to know the consumption of raw materials per 1 sq. m.
It is calculated using the formula:
… Where 13.40 kg / mm is the constant factor, D is the wire diameter (mm), A is the mesh diameter (mm).
If you substitute numerical values, you get:
Now you need to calculate the cost of the Rabitz roll:
where 0.62 kg is the cost of 1 sq. m mesh, 15 sq. m - the number of meters of chain-link in one roll, 37 rubles. - the cost of the material.
Hourly productivity with an automatic machine - 44 rolls. This means that within 22 work. days (8-hour shifts) production results will be 116160 sq. m or 7744 rolls.
Their cost will be equal to:
1) What are the production costs?
| Cost category | Sum | Note |
|---|---|---|
| Total capital investment required: | 1 001 100 rub. | |
| Salary to employees | 80 thousand rubles | It is desirable to hire two people, one of whom will be an auxiliary worker, and the other - a shift supervisor or a sales manager. The latter will be responsible for observing the mesh production technology, overseeing the work of subordinates, and taking care of the movement of the chain-link in the warehouse. |
| Monthly payroll tax | almost 25 thousand rubles. | - |

What investments are required? Pros and cons of business.
2) What amount of income can you expect?
We found out the volume of production of the Rabitz for the month - 116160 sq. m, which is equivalent to 7744 rubles. If you put a 30% mark-up on each roll, their retail price will be 447.3 rubles / piece.However, in practice, a roll of chain-link mesh, the production of which took place in accordance with a mesh size of 55 * 5 mm, is sold at a price of 700 rubles. For 1 sq. m you can take 50-52 rubles.
Monthly revenue:
Net profit:
- RUB 5,420,800 - 2 664 710.4 rubles. - 436 100 rubles. - 790,000 rubles. = 1,529,989.6 rubles.,
- where RUB 5,420,800 - revenue, 2,664,710.4 rubles. - the cost of the Chain-link, 211,100 rubles. - expenses, 790,000 rubles. - taxes.
As you can see from the calculations, the production of chain-link mesh is a profitable business. And due to the simplicity of the technology, this option is suitable even for those who do not have much experience in this area.

The production of a chain-link mesh for someone can become a profitable business, and for someone it will help to save the family budget as a result of refusal to purchase it. The main thing is to immediately decide for what purpose it was decided to start this production, and approach it with all responsibility, having calculated your capabilities, investments and benefits from this business, choosing the necessary premises, equipment, suppliers of raw materials and personnel when it comes to large volumes.
1
Making chain-link mesh is a very profitable business, although it depends on the season. It does not require large investments (both at the stage of opening this business and in the process of doing it), numerous personnel and large production areas, since all the necessary equipment is compact, regardless of its design. In addition, there are no special requirements for the room chosen for the production of this woven mesh. Depending on the scope of the intended production, from one to several workplaces can be equipped in a basement, shed, garage, warehouse.
Mesh-netting production
Each place will require only 10-15 m 2, which will accommodate a table and a machine for knitting a chain-link. And you also need to allocate some space for storing raw materials and finished products. Its area, of course, will depend on the volume of production and the speed of implementation of the grid, but should be at least 10 m 2. There will be no problems with the choice of equipment either. You can always find a suitable manual, semi-automatic or even automatic machine. Manual control equipment is unproductive, and it is usually used to make chain-link only for their own household needs.
And for the production of mesh for sale, as a rule, they choose semi- and automatic machines. They require a three-phase power supply. A chain-link is produced of several types, the division into which is determined by the shape (rhombic or square) and dimensions (in the light from 5 to 100 mm) of the cells, as well as the thickness of the wire used (diameters from 1.2 to 5 mm) and a number of other characteristics of the finished product. The technical requirements for the mesh and its range are regulated by GOST 5336-80.
You can read about the division into types, characteristics and application of these products in the article. Within the framework of this article, it should be noted that the most popular is a mesh made of wire with a diameter of 1.6 mm. And the most common version of weaving a chain-link is with square cells. Standard size of the product: length - 100 cm and height - 150 cm. But manufacturers make chain-link with other dimensions when the customer requires it. The finished net is rolled up for easy storage and transportation. The wire needed for manufacturing can be purchased at almost any organization that sells building materials (in a store or at a base).
And even if there is no raw material there due to low demand due to the rarely used diameter or type of coating, then the wire can be ordered. It will be delivered as soon as possible.

This is the simplest production option that does not require complex economic calculations. The room for it can be any of those listed above in the first chapter. And you can make simple equipment yourself. If you want to make a factory-quality mesh, you will need to purchase a manual machine with suitable characteristics and cost. In general, the manufacturing process for this woven mesh consists of twisting the wire in a specific manner.
Types of mesh-netting
How to weave it yourself and how to make the necessary equipment is discussed in the article. Even if the grid is needed only for arranging the fence of your own site, then in the case of self-production of devices for its production, the savings in the family budget will be a very tangible amount. And how to make a fence using this product is described in the article.

Much wider than most people think. It is used not only for fencing areas for various purposes, but also for thermal insulation work, sifting bulk materials, fixing walls and arches of mine workings and mines. So, by and large, there should be no problems with its implementation.
Mesh-netting in rolls
However, before starting a large-scale production of a chain-link for your own enrichment, you should definitely draw up a business plan. It should contain the following items:
- analysis of the market and potential competitors;
- options and markets;
- description of the project;
- calculation and analysis of start-up capital;
- possible risks;
- personnel and equipment;
- advertising (if you go directly to large consumers, you may not need it);
- calculation of profitability and payback time of production.
As noted above, large-scale production will require semi-automatic or automatic machines. The selection of premises and personnel depends on the choice. For automatic machines, you only need an operator who sets the required parameters on the control panel and loads the wire into the receiving device.
When calculating financially, it is necessary to take into account:
- Raw material cost. For example, 1 ton of wire with a diameter of 1.8 mm with a zinc coating costs 70,000 rubles. A standard roll (dimensions shown above) will take about 10 kg. That is, you need to spend 700 rubles for raw materials for one roll.
- Equipment energy costs. One roll of mesh is produced in less than an hour. Therefore, approximately the energy consumption per 1 roll is equal to the power of the machine, and the costs are calculated by multiplying this value by the tariff.
- Estimated salary of staff, depending on their qualifications.
- The costs of renting premises, taxes, transport for the delivery of products to the customer.
- Wholesale and retail cost of 1 roll of chain-link (around 1000 and 1600 rubles).
- Competitor prices.
As a result, the profit from the wholesale of galvanized wire mesh with a diameter of 1.8 mm can be up to 200 rubles (plus or minus) per 1 roll. Then in a month, when 440 rolls are made on 1 machine, the production of chain-link should bring 88,000 rubles.

For the production of mesh, wire is used made of low-carbon steel and offered in three versions: uncoated, galvanized and coated with polymer material. In rare cases, stainless steel wire is used. Obviously, the chain-link made from low-carbon raw materials without coating will be with the lowest cost price. And the most expensive one is made of stainless steel.
Features of wire mesh-netting
Considering that the chain-link is mainly used outdoors, and in other cases of use it is exposed to influences that cause corrosion, it is usually made of galvanized wire. At the same time, for the fabricated mesh, an important criterion is the thickness of the zinc coating. It is expressed in the amount of zinc applied to the wire. In the CIS countries, galvanized wire is most often made by hot-dip galvanizing. This method of applying zinc to steel is the most reliable both in terms of the durability of the resulting coating and the protection of the product with it from corrosion.
The zinc content on the wire surface is 70–90 g / m 2. A mesh made from such raw materials will serve, without being covered with rust, for a long time - about 20 years. The modern method of galvanizing, which is often used now, is electrolytic, which provides a coating with a zinc content in the region of 10 g / m 2, which is much less reliable. A mesh made from such raw materials will rust very quickly - within 2 years of its operation.
A chain-link made of low-carbon uncoated wire is in almost the same demand as galvanized steel. This is due to its low cost. However, this mesh should be painted after fabrication to protect it from corrosion. This is done either by the buyer himself after purchasing the product, or by the manufacturer - at the request of the customer and for an additional fee.
If the chain-link is operated in a humid sea climate (on the coast of the sea and in the surrounding areas), then even a hot zinc coating will not protect it for a long time. The mesh will begin to deteriorate much earlier than 20 years later. The reason is the high content of salts and moisture in the air. In this regard, in such regions, the chain-link is usually made from low-carbon raw materials with a polymer coating.
An article about the production of a chain-link mesh, a machine (equipment for it), calculation of profitability, video of the manufacturing process, approximate prices for one roll. Suitable as an example for a business plan.
Basically, the netting is used for fencing areas. If it is not protected from rain, then immediately after the first rainfall it will be covered with rust. The chain-link mesh is protected from corrosion in several ways: painting, galvanizing and using a polymer coating. The most common way to protect the mesh netting from corrosion is galvanized. Manufacturers, as a rule, do not paint, since all the paint simply follows due to the constant friction of the mesh in the rolls.
Consider information that will help you in drawing up your business plan for this business.
Equipment for the production of mesh netting - machine
In order to organize your business for the production of chain-link mesh, you first need to buy all the necessary equipment. These can be either automatic (automatic) or semi-automatic machines.
Video of the production process with a simple machine:
Semi-automatic machines require an operator who monitors the entire production process and is directly involved in it. Such a device is easy to use, easy to set up, relatively small in size and cost about 40,000 rubles.
Using automatic machines, you will be able to organize production in such a way that all its processes will take place automatically without the participation of an operator. But the price for such a machine will fluctuate between 200,000-250,000 rubles.
Video of the machine:
Such an automaton is quite compact.
The monetary costs that go to the purchase of a machine for the production of a chain-link mesh will have to amount to 35,000-40,000 rubles.
Before buying a machine, you need to find a production facility. It can be a warehouse or a garage. The area of the selected room should be 10-20 sq. meters. The room is used for the production and storage of the finished chain-link mesh. In most regions of Russia, monthly rent of such premises will cost several thousand rubles.
Wire for the production of chain-link mesh and its corrosion
In order to master the machine and get the first batch of chain-link mesh with it, you need to purchase wire. 500 kg of net worth 17,500 rubles is enough for you.
Low-carbon steel wire is used as raw material for the production of the netting. Along with steel wire, polymer coated and galvanized wires are used. It is extremely rare for a chain-link mesh to be made of stainless wire.
Most mesh "coated" chain-link is made from galvanized steel wire. Therefore, the amount of zinc on the galvanized wire is very important. Most of the factories in the CIS countries cover the wire with zinc by hot-dip galvanizing. With this method, the zinc content on the wire ranges from 70 to 90 g / m 2. The mesh netting made of such wire will not rust for 20-25 years. Recently, they began to master the coating of wire by the electrolytic method. But when the wire will contain only 10 g / m 2 zinc, which, in turn, is very little. A mesh made from such a wire begins to rust within a year or two after the start of its operation.
However, if the chain-link mesh is operated on the coast of the salty sea, then even a large amount of zinc cannot save it from corrosion. In such areas, it is recommended to use polymer coated steel wire mesh.
Calculation of income and expenses
Here are the average values, so in your case the numbers may differ both up and down.
Raw materials
We calculate the costs that go to the production of one roll of chain-link mesh. One ton of wire costs about 35,000 rubles. The weight of a roll of mesh of a chain-link made of wire having a diameter of 1.6 mm and a mesh size of 55 mm will be approximately 9.5 kg. The cost of such a roll, taking into account the amount of wire spent, is 333 rubles.
Wages to workers
As a rule, the salaries of employees in large cities are higher than in small towns, and even lower in villages. We will consider the wages of the machine operator using the example of Stary Oskol. Let it be 16,000 rubles in 22 working days. Let's take into account that it is better to pay the salary depending on the number of mesh rolls produced. During one shift, 11 rolls or 22 rolls are produced per day. Then the production of one roll should be paid 70 rubles.
Electricity costs
The price of 1 kW / h is approximately 4 rubles. The energy consumed by the machine for the production of the chain-link mesh is 1.5 kW / h. But in addition to making the mesh, rolls are also packed and loaded onto racks. This means that a little less than 1.5 kW / h will be spent in 1 hour. Then we assume that 1 kW / h of energy is spent for the manufacture of one roll of chain-link mesh.
Premises for rent
The rent for the premises will be calculated as a share to one roll of netting netting produced. 22 rolls will be produced in one day. In 22 working days (1 month) - 484 rolls. As a result, we get an amount of 2-4 rubles.
Additional costs for taxes, transport, etc. will be 10-20 rubles per roll.
Total cost
For one roll of mesh, a chain-link made of 1.6 mm wire and a mesh size of 55 mm, the cost price will be as follows:
Wire price (333 rubles) + worker's payment (70 rubles) + electricity costs (4 rubles) + rent (2-4 rubles) + additional costs (10-20 rubles) = 419-431 rubles ...
Production profitability
Having calculated the production cost of one roll of netting netting, let's calculate the income per one roll of netting. To do this, you need to find out the cost at which the produced mesh will be sold. In turn, for this you need to study the prices of competitors' products.
The wholesale price for a mesh netting with a mesh size of 55 mm and made of wire 1.6 mm thick is about 600 rubles per roll. The profit should be:
- 600 - 419 = 181 rubles.
- ... or 600 - 431 = 169 rubles.
The calculations were made taking into account the fact that the average retail price for a chain-link netting in Russia is about 1000 rubles.
To calculate the monthly profit, you need to multiply the obtained values by the number of rolls that are produced in one month. In our case, it is equal to 484. Then the monthly profit should be 87604-81796 rubles.
According to the calculations obtained, we conclude that the costs that we have at the initial stage can be recouped in just one month. In addition, you can organize the sale of the netting netting at a higher retail price.
The chain-link mesh as a structural material was invented and patented in 1878 by Karl Rabitz. A chain-link mesh is made of low-carbon metal steel wire, often with a polymer coating or galvanized. It is rare to find a stainless steel wire mesh.
Let's try in this business plan to figure out whether it is so profitable to produce a netting netting (hereinafter referred to as netting) and how much you can earn on it.
Wire for the production of chain-link and its corrosion
The mesh of the chain-link in the shape of the cells is of two types: rhombic (acute angle of 60 degrees) and square. The chain-link, as a rule, is supplied in rolls, the roll height is 1.5 meters, the length is 10 meters. But you can order other sizes, for example, heights from 1 to 4 meters, and the length of the mesh up to 18 meters. The ends of the mesh rolls are packed in thick paper, burlap or polyethylene.
90% of the mesh produced is used for fencing the area, which is why moisture protection is so important in the production of this material. Protect the chain-link in several ways: painting, galvanizing or polymer coating.
Galvanizing is the most common method. On galvanized wire (hot-dip galvanized method), the zinc content is 70 to 90 grams per m2. A mesh made from such a material will not rust for 20-25 years. There is another method of galvanizing wire - the electrolytic method. With it, the zinc coating is from 10 g / m2. and as a result, the mesh made of such a wire will be covered with rust in two years.
In addition to rain, salt water can also cause rust on the mesh. Therefore, for such conditions, it is better to use a polymer-coated steel wire mesh. If there are scratches or cuts on the coating, then such a mesh is not of high quality and soon in these places the mesh will be covered with rust, the coating will burst.
The painting of the chain-link is mainly done at the installation site. If you paint it in production, then the paint will rub off in the roll and the protection will not be of high quality.
The strength of the chain-link depends on the size of the cell and the diameter of the wire. The smaller the mesh and the larger the wire diameter, the stronger the mesh. Since the cost of the chain-link mesh is the price of the wire from which it is made, some entrepreneurs overestimate the size of the mesh and reduce its diameter.
In civilian conditions, the diameter of the wire rarely exceeds 2 mm. The most commonly used wire is 1-1.5 mm. It is quite simple to calculate the wire consumption for making 1 m2 of mesh. Formula for calculating 1m2 of chain-link:
13.40 * D2 / A, where
· 13.40 - coefficient corresponding to the consumption weight;
· D2 - wire diameter squared;
· A - the size of the grid cell. If the size is 50 * 50, then we count 50, if 35 * 35, then 35.
For the calculation, we will use a galvanized low-carbon wire with a tensile strength of 560-900N / mm2, a diameter of 1.6 mm. The wire consumption per 1m2 of the chain-link according to the formula will be 13.4 * 1.6 * 1.6 / 50 = 0.69 kg. Now, in order to find out how much wire we need for a shift, for a month of work, we need to select the equipment suitable for us and find out the production volume of the machine.
Equipment for the production of netting and production room
The bulk of the costs, as in many other types of business, goes to the purchase of equipment. If you go to the Internet and look for equipment for this production, you will see many machines for making netting mesh from different "Kulibins". We will not dwell on such manual machines for making chain-link mesh, but consider only what plants for the production of certified equipment offer.
Equipment for the production of chain-link can be semi-automatic and automatic.
Semi-automatic equipment for the production of chain-link mesh
When using this equipment, manual labor is compulsory, even for operations such as folding the net. As a result, asymmetry of the cells and other disadvantages can be seen in the finished product. The advantage of this equipment is ease of assembly and setup, takes up little space and is inexpensive. The cost varies from 20,000 to 35,000 rubles.
Automatic equipment
Automatic equipment is more expensive, the cost starts from 200,000 rubles (used 150,000 rubles). For this equipment, the use of the presence of the operator is minimal, high productivity, accuracy of weaving.
For our business plan, we will consider the purchase of semi-automatic equipment, since a garage will be used for work. We will produce a standard roll of 1.5 * 10, with a mesh size of 50 * 50. Equipment with this cell size can produce 18 rolls per day. The area for equipment is 1-1.5 m2, power is 2.2 kW / h. The cost of equipment, a table for a machine tool and other necessary tools is 30,000 rubles.
Choice of organizational and legal form
For this type of business, it is better to open an individual entrepreneur, it is easier and cheaper. It is more expensive to open an LLC, but you do not need to pay contributions to the pension fund with an individual entrepreneur. And since in the first months of the existence of a business, and maybe even a year, there may not be much profit, it is more profitable from a material point of view to open an LLC.
Taxation - STS (simplified reporting system), income minus expenses.
The production of the netting of the chain-link is regulated by GOST 5336-80. For the best sale of products, it is recommended to undergo voluntary certification.
Calculation of income and expenses
Let's calculate the work of our production for a month.
Revenue. On the equipment we have chosen, it is possible to produce 18 rolls of chain-link mesh per day. Thus, in a month 18 * 20 = 360 rolls. The cost of selling a roll is 500 rubles or 360 * 500 = 180,000 rubles.
Expenses. To run a business, you need one employee, a salary of 15,000 rubles, payroll taxes, 4,500 rubles. We will run our business in our own garage, so there is no need to spend money on rent, electricity is 1,980 rubles per month, wire consumption is 18 * 20 * 1.5 * 10 * 0.69 = 3,726 kilograms. The cost of the wire is 35,000 rubles / ton or 3,726 * 35 = 130,410 rubles. Other, including transportation and packaging costs may amount to 10,000 rubles.
We collect all expenses: 15,000 + 4,500 + 1,980 + 130,410 + 10,000 = 161,890 rubles. It turns out that if you sell all the wire produced in a month, the net profit will be 180,000-161,890 = 18,110 rubles.
The main channels for the implementation of the mesh-netting
Your product can be sold through retail stores, wholesalers, agricultural markets, as well as direct sales to individuals. Implementation through tenders is also possible, but for beginners it is quite difficult.
Output
The main conclusion on the manufacture of a chain-link mesh as a business is that it will not be difficult to produce the product itself, the main thing is its sales.
Nowadays, most summer residents prefer to use them for fencing their plots and for the logical distribution of the terrain into sections.
The chain-link mesh is an invention of the engineer Karl Rabitz, who at one time came up with the idea of using rolls of knitting wire to create an effective, very convenient and at the same time quite cheap fence.
1 Features of mesh and wire
The chain-link mesh is a special type of mesh made from braided wire. The wire is taken thin, up to 3 mm in diameter. Most often, samples with a cross-sectional size of 1-1.5 millimeters are used.
The wire is knitted on a special machine, interwoven into a mesh with rectangular cells of certain sizes.
The convenience of using a chain-link mesh is obvious. Its weight is quite low, you can assemble the structure yourself. Wire consumption is comparatively small, easy to determine and does not hit the budget.
At the same time, the fence performs its tasks. Its dimensions are sufficient to qualitatively protect the site from the street, thereby protecting your space from unwanted guests, animals, etc.
They use it for a wide variety of tasks, from fencing animal enclosures to full-fledged fences at security companies.
The wire itself plays an important role. It is the only and main component of the mesh, therefore its characteristics, dimensions and thickness have a huge impact on the final result.
See also: what are the advantages, and where can it be applied?
In terms of the diameter of the section, as we have already noted, the samples are selected rather thin, their thickness rarely exceeds the 2 mm mark.
For a large-sized mesh, the use of which is reasonable in army or industrial facilities, models and thicker can be used, however, in civilian conditions there are no particular advantages from it, and the cost of producing a thick mesh of the chain-link is much higher.
1.1 Coverage
The second point is coverage. The coating of the wire affects how long it will last under the operating conditions.
By the type of coating, the wire for the fence the chain-link is:
- Black.
- Polymerized or plasticized.
Black wire is a wire for a fence that has not been processed by anything. It is cast from standard grade rough steel. This steel is very good and is perfect for fastening a fence, if not for its weak resistance to corrosion.
The fence mesh made of a black wire sample will begin to rust in a few years, and after a dozen it will completely rust. Not that this is a very big problem.
The fence will not crumble due to rust, but will lose its presentation, as well as the initial strength indicators.
Galvanized wire mesh is the simplest and most effective solution. Galvanized mesh withstands the influence of external factors longer, less likely to corrode.
However, galvanized products will also begin to deteriorate over time, but much later. But it is more durable, is not inferior to the first option in strength and does not cost much more.
Polymerized or plasticized mesh is the most popular and convenient option. Here, steel wires are coated with polymer compounds, forming a kind of protective sheath.
2 Manufacturing
Many are interested in whether it is possible to create a chain-link type mesh with their own hands. After all, modern manufacturers have managed to use a minimum of equipment and materials for such tasks.
Indeed, in order to form a high-quality mesh, huge workshops and production lines are not needed. It is enough to have a single high-quality material.
The chain-link is not weaved by hand... It is a hard, ungrateful and monstrously slow mode of production.

It is much more reasonable to use modern automatic or semi-automatic ones, where the process is reduced to cutting wires of the required length, feeding them to the machine, and then braiding them in the right order.
This work is performed by the machine operator. During a shift, he makes several tens of square meters of mesh with cells of 50 × 50 mm. It is impossible to give exact performance indicators, because a lot depends on the type of wires, the efficiency of the machine, the size of the cells, the efficiency of the operator himself, etc.

2.2 Material consumption
Material consumption is easy to detect. For this, there is an understandable and easy formula that allows us to quite accurately understand how much production is needed and how much it will cost us.
The formula is based on the ratio of several indicators. The nominal weight of raw materials for the mesh, the mesh size of the mesh (the mesh size directly affects the consumption) and the wire diameter are taken into account.
So, consumption formula for 1 square meter of chain-link as follows:
13.40 * D 2 / A, where
- 13.40 is a constant coefficient corresponding to the consumable weight;
- D 2 - wire diameter squared;
- A is the size of the cell (if the cell is 50 × 50 mm, then in A we write 50, if 35 × 35 mm, then in A we write 35, etc.).
The result is the weight of the wire, or the weight of the roll, which must be used to form 1 square meter of chain-link of the required dimensions.
For a standard chain-link intended for use in civilian conditions with a cell size of 55 × 55 mm, the weight of the material used, and therefore its consumption, is 0.6 kg per 1 m 2.

Using such a simple, but at the same time effective scheme, you can easily determine the weight and consumption of any types of chain-link.
2.3 Manufacturers
Weaving a chain-link is permissible and profitable only if you are absolutely confident in your abilities and clearly understand why you need it.
Buying even a hand-held machine is a serious investment. They will not pay off as soon as you might want.
That is why, for trivial and small tasks, it makes sense to simply turn to well-known manufacturers and buy products of the quality you need.
Fortunately, there are too many manufacturers on the market. The process of weaving a chain-link is so simple that factories for its manufacture are located in almost every major city.
- UkrTransMetal;
- Private Enterprise "Hardware-94".
The former are engaged in large-scale production of a huge amount of metal and wire products, from knitting clamps for fittings to full-fledged protective sections.
The latter are less popular, but they offer their products at a lower price with excellent quality.
The wire for the chain-link from these manufacturers is very high quality and durable, it is sold in a huge number of varieties.
2.4 Installation
An interesting point concerns the fastening of the mesh as a full-fledged fence. They use different ways for fastening. The choice depends on your wishes and working conditions.
So, the simplest and at the same time very effective way is to plant the chain-link in advance. Fasteners in this case are made from cheaper or special fasteners.
If the situation requires it, then a rigid wire or thin reinforcement is passed through the lower and upper parts of the cells. It will stabilize the plane of the fence, making it much more stable.
The second mounting option is the installation of individual sections, where the previously cut chain-link is attached to a full-fledged section, consisting of a metal frame, and then, as a component of the fence, is planted on ready-made monolithic pillars.
Such a structure is considered much more mobile, it is easy to repair and modify it, but it will take more time to work, the help of a welder may be needed. This, in turn, increases the final cost of the fence.
