The base is steel wire with a diameter of 3–5 mm. The average size cells - 100*150 mm, popular shapes - square, rectangle. Available in cards (sections in the shape of a square) measuring 2*2.5 m.
All bars welded mesh fastened together at intersections spot welding, hence the name.
It is considered the most durable and reliable type for fencing.
Every sectional element The wire is supplemented with stiffening ribs, which significantly increases the stability of the finished structure.
Available in the following colors:
- blue;
- red;
- white;
- green.
Welding technology is performed in two ways:
- Pre-galvanized. A significant drawback is that when connecting rods by welding, part of the galvanizing peels off, which causes corrosion on the metal surface.
- Galvanizing after welding. Much more effective than the first method. The fence will be more durable and more resistant to the external environment. It is possible to apply an additional polymer layer.
Majority welded fences made with protrusions that prevent intruders from entering the territory.
Sectional mesh is used for modular fences around country cottages, sports grounds private type, industrial buildings.
While creating decorative hedge Corrugated rods can be used, which visually make the patterns three-dimensional. Welded mesh with a 3D effect will look beautiful and will last at least 20 years.
Among the main advantages of this material are:
- choice of any fence height;
- quick assembly of sections due to the complete set of fasteners;
- the ability to replace the old card with a new one;
- strength, resistance to mechanical damage;
- aesthetics.
Flaws:
- high price;
- heavy weight, which requires the involvement of assistants during the installation of sections;
- If the mesh is not galvanized and there is no polymer layer on it, the fence will have to be painted periodically.
For installation of spans you will additionally need metal corners and profile pipes.
Grooved
Photo: football field perimeter fence Another name is canned. Made from black carbon steel. The wire profile is bent, giving it a wave-like shape. The rods are then woven together like thread to produce fabric. It has high strength and rigidity, due to which it is produced not in rolls, but in cards.
The diameter of the rods ranges from 2 to 7 mm.
For country and sports fencing, corrugated mesh up to 3 mm thick is sufficient.
The cell sizes are different: from 1*1 to 10*10 cm. For fences, it is better to take material from largest size cells.
Such raw materials will become the basis of a strong and reliable fence, but its only drawback will be its high cost.
With polymer coating (Euro mesh)
If you choose durable and at the same time beautiful material for fence affordable price, then Euro mesh, one of the welded types, is perfect. It is made of interlaced steel wire, covered with a layer of PVC on top. The polymer is applied by baking.
Diameter - 2.5 mm. The size of the cells is 50*50, 100*50 mm. It goes on sale in rolls. Each height is 2 or 1.5 m, length is 25 m.
Photo: using Euro mesh as a fence for private territory Pros of a grid with polymer coating the following:
- provides high rigidity designs;
- durable and reliable;
- is inexpensive;
- does not fade, does not crack;
- resistant to moisture and temperature changes.
- presented in different colors;
- looks beautiful.
One square meter Such a fence will be several times cheaper than a fence made of chain-link, wood, siding or corrugated sheets, and the service life of the Euro mesh is not inferior to any of the other types.
If the surface of the mesh is damaged, the unprotected steel begins to rust, so you need to select the mesh carefully, inspecting the surface for cracks and defects.
Lightweight
Made from thin wire resembling thread. The transverse and longitudinal rods are attached to each other by a hinge unit. The size of the cells within one roll varies. First there are cells with a height of 15 cm and decrease with each row to 5 cm, then increase again. This type of weaving provides the mesh with sufficient strength, despite the fact that the wire is thin.
Photo: using lightweight mesh as a temporary fence This is the cheapest type metal mesh, but it is recommended to use it only during installation temporary fencing, since its service life does not exceed 5 years.
Gabion
This original fence is made from rectangular, square, cylindrical welded or twisted wire boxes, the cells of which can have different shapes and sizes. Moreover, the boxes are not left empty, but filled natural materials(cutting trees, stones, rubble). This is an innovation in landscape design will make the fence a decoration for the estate.

It is created from extruded polymer fibers that are intertwined to form a mesh. Often used:
- as a garden lattice to separate areas of flower beds and front gardens;
- as the main fence for a summer cottage;
- for emergency construction (in rare cases).
Sold in rolls, weighs little.

Among other advantages plastic mesh highlight:
- Installation speed. Roll material allows you to assemble fences without unnecessary joints and additional fastenings.
- Easy to transport due to light weight.
- Large selection of colors and cell shapes.
- Resistance to any influence of the external environment.
- Design safety. There is no risk of injury, unlike metal mesh.
- Does not require maintenance.
- Service life up to 40 years.
- UV resistance.
- Non-toxic.
A significant disadvantage of PVC mesh is low strength. Such a fence will not protect the estate from intruders, so it is better to use it for zoning the site.
Camouflage
Another name is camouflage. A great addition to the regular grid. Protects the garden area from scorching heat sun rays, prying eyes. Previously it was used only to camouflage military installations. Now used by private sector owners.
Photo: decorating the pier with camouflage netting Photo grid
Used to decorate finished fencing. It is made of polymer fabric, on top of which an image is applied.
- solid (standard banner fabric);
- mesh.
For fences, the second type of photo mesh is used due to the lack of windage during wind and good air exchange.
This fence is not visible from the street. This spectacular decoration of the estate will not cost much.
The outer part of an unsightly fence is decorated with a photo grid, construction works, places of rest.
From fabric
It is made from thin metal wire with a diameter of no more than 0.03 – 3 mm with the addition of polymers. Perpendicular weaving is performed on automated machines. The cells are very small in size. Woven mesh is sold in rolls. Rarely used for fencing, more suitable for camouflaging construction work.
Photo: using fabric mesh as temporary fencing during construction How to choose a quality mesh
To do this you need to know a few secrets:
- If you purchase a corrugated mesh for a fence, then you should take cards with large cell sizes so that light can better pass through to the area.
- The quality of the welded fabric can be determined by opening the roll and checking the wire density for tensile strength. At the junctions metal elements should not lag behind each other.
- At the time of buying metal coating It is recommended to clarify by what method the zinc layer was applied. Hot-dip galvanizing is considered the most reliable. But the electrogalvanic method is not the most durable treatment and is more often used in decorative purposes than in protective ones.
- On a surface polymer mesh There should be no chips or cracks. Special attention pay attention to the joints.
- The edges of any canvas must be carefully trimmed and folded.
- All cells must be smooth and identical.
Most important point ‒check the correspondence of the actual mesh parameters to those specified in the documentation.

Installation of finished sections 2.5 m wide from galvanized mesh with cells 50*50 mm, 2 m high will cost 1150 rubles. Sections of welded wire decorated with patterns will cost twice as much.
With a competent approach to choosing fencing mesh, you can find quality material at an affordable price that will last a long time.
In modern times, metal mesh is used in various industries and in household. You cannot do without it when preparing the foundation or building a house. It is also used in the process of laying walls, as a fastening link, and for making fences. It is highly valued due to its unpretentiousness to weather changes, durability and strength. This article will discuss the types and subtypes of metal mesh, their advantages and purpose. Now on the market you can find the most various brands metal mesh different quality, for example, the StroySetka Company offers construction meshes High Quality at affordable prices.
There are 4 main advantages of metal mesh:
1. Its simple design makes it easy to operate.
2. Convenient packaging in cards/rolls and low weight greatly simplify installation, transportation and storage.
3. Resistance to temperature changes and precipitation.
4. Excellent strength characteristics, thanks to which the mesh is usually used for many years, maintaining its original properties.
Types of metal mesh
There are the following main types of metal mesh and their subtypes:
Chain-link mesh (woven non-galvanized in PVC, woven mesh in PVC, woven non-galvanized chain-link, galvanized woven chain-link);
Expanded metal mesh, which can be uncoated or galvanized;
Welded mesh (from VR-1 wire, from galvanized wire, hot-dip galvanized in rolls, non-galvanized heavy-duty winding, in cards of galvanized wire, non-galvanized in PVC, non-galvanized in PVC LEPSE-Lux, non-galvanized in rolls);
Woven mesh (stainless steel "micro", non-galvanized, stainless steel GOST 3187-76, stainless steel GOST 3126-82).
Rabitz
Due to its versatility and high level of strength, chain-link mesh is used in different areas: for creating fences, metal beds, reinforcement for plastering, etc. This material is characterized long term operation: up to 50 years normal environment, and 7-10 years under aggressive conditions. This type of metal mesh is quite easy to care for, and it retains its attractive appearance for a long time. Such a mesh is inexpensive, even despite its advantages (the cost will depend on the diameter of the cells and the thickness of the wire).
TsPVS mesh
This type of mesh is one of the substitutes for woven plaster mesh. Experts consider it an alternative to conventional metal mesh. It is made by the expanded metal method and is used in many fields. During technological process its production does not waste material and produces a minimal amount of waste. It is produced with or without zinc coating. Let's consider the areas of its application:
Reinforcement at plastering works Oh;
During façade and facing works natural stone and tiles;
Flooring construction scales and sites, and in industry for sifting rock and making containers;
Creation of original design;
Manufacturing of trays in industry (food), cages;
Production of tractor and automobile filters, ventilation grilles.
Among its advantages are: excellent adhesion to the surface, transparent structure, flexibility, high strength, structural integrity.
Welded mesh
Metal mesh (welded) is the most the best option for reinforcing concrete/brick structures, as well as for constructing various fences. Let's take a closer look at its varieties and their purpose:
A galvanized mesh made from VR-1 wire is suitable for creating cages/enclosures in animal farming;
The mesh of reinforcement in cards is optimally used for reinforcing structures (concrete);
Welded mesh (galvanized) in rolls is suitable for plastering work and organizing temporary fencing;
Products made from low-carbon steel are often used in cards for constructing and reinforcing floor screeds.
Woven mesh
This type of metal mesh is a structure that consists of strong alloy/low-carbon wires (up to 3 mm in diameter). To make it, the method of weaving strands is used. The strands are arranged perpendicular to each other. The cell sizes of the woven metal mesh are up to 20 mm. This product comes in rolls.
Metal mesh is a very simple element of a huge variety building structures. But behind the unpretentious simplicity lies many subtleties, features, types and subtypes of this building material. This article will help you understand the main types of metal mesh, help you choose one or another type of mesh that is suitable specifically for your needs, and will also help you choose the required quality.
The list opens with a simple welded mesh (GOST 3282-74), its name fully characterizes the method of its manufacture. These are rows of perpendicular steel wire welded at the intersection points. Most often you can find a mesh with a width of 1 or 1.5 meters; less often, wire with a width of 1.3, 1.8, 2 meters is found. As a rule, the length of the mesh roll reaches 25-30 meters. The diameter of the wire rods varies between 2-4 millimeters, and different cell sizes from 6 to 50 mm and different shapes(square or rectangular). It should be remembered that what smaller size cells, the greater the margin of safety the mesh will have. Since steel is very susceptible to corrosion, it is characterized by galvanizing (the process of applying zinc). Technically, there are four types of galvanizing, but without going into detail technological features, we can say that the amount of zinc will be directly proportional to the service life, which should be paid attention to when purchasing. Polymers are used as an option for corrosion protection. And here you are important advice- check the diameter of the steel core in such structures, because the strength of the mesh is the key to long service. The polymer coating, of course, will significantly increase the resistance to moisture, salts and other chemical influences, but will not be able to compensate for the density of steel. Welding mesh is used for: reinforcement road surface, masonry, floors, plaster, as well as for the manufacture of cages (aviaries), greenhouses and fencing the territory. Such metal mesh is an example of a simple but very practical design that facilitates the construction process and carries a number of useful functions. You can find the most different variants, satisfying any needs, so the Interstroy company has the most diverse grid on this website www.interstroynn.ru.
Next it is worth mentioning construction material in the form of a reinforcing mesh (GOST 23279-85). It's not hard to guess reinforcement mesh is a mesh made of reinforcement (more precisely, corrugated wire) welded from perpendicular rods at their intersection points. Metal rods have a diameter from 3 to 40 mm (divided into heavy rods with a rod diameter of 12 mm, and light rods with a rod diameter of up to 10 mm), the cell size can vary from 50 to 250 mm. This type metal mesh is extremely widespread, the range of applications of reinforcing mesh is unusually wide. Despite its impressive size, it can be used as a mesh for plaster, although more often, of course, it is used as a material for strengthening the wall frame or reinforcing the foundation. Excellent for reinforcement brickwork, erection of fences, construction of enclosures and cages. Just like simple welded mesh, reinforcing mesh can be galvanized or coated with a layer of polymers to improve protective properties in the face of corrosion from moisture and aggressive chemical influences. Covered protective layer reinforcement mesh can effectively and for a long time serve as a fence or enclosure without giving way negative impacts environment.
Please love and favor mesh, familiar to everyone and everyone (GOST 5336-80). This grid is named after its German ancestor, the German inventor Karl Rabitz (also known as Rabitz) back in 1878. The mesh manufacturing process is very simple, special machine wire spirals are screwed into one another. The raw material is small diameter steel wire with low carbon content to ensure high level elasticity and flexibility. There are mesh options made from of stainless steel or aluminum. But due to the imperfection of these materials in relation to chain-link, they are not very popular among consumers. Of course, here too there is a tendency to coat the mesh with polymer and galvanizing, which in turn significantly increases the service life and resistance to an aggressive external environment, which is especially important due to the small diameter of the rod and its insufficient resistance weather conditions, as well as chemical influences. It should be remembered that galvanized chain-link in a salty environment (near the sea) can oxidize, despite the quality and quantity of zinc, and here a polymer one will be much more acceptable. Average height The roll supplied to the market is 1.5 meters, the average length is 10 meters. However, as a rule, the manufacturer can fulfill an order for a height of one to four meters, with a length of up to 20 meters. You should definitely pay attention to the ends of the mesh rolls; they should be tightly packed in strong paper, burlap or artificial fabric. The mesh is perfect for installing fencing and assembling an enclosure, and can also sometimes be used for applying plaster.
In the process various works Construction mesh is often used on a construction site. Today it is represented by several varieties, and they all have their own performance characteristics and purpose.
IN modern construction The most commonly used types of meshes are:
Catching mesh
Such products are intended for installation on both already erected and high-rise buildings under construction. The catching mesh serves to prevent the possible fall of building materials, workers and all kinds of tools, and even icicles from roofs from a significant height.
A modern catching mesh can withstand the fall of any object from a height of 6-7 meters, and its weight can reach 100 kilograms. It is fixed on a special metal structure in the form of a frame, which in turn is attached to the supports. The latter can be either the wall of the structure or scaffolding.
Masonry mesh
This design is used as a reinforcing element for both concrete and stone floors. Masonry mesh consists of metal wires welded together at an angle of 90 degrees. The wire used to produce the mesh can have a diameter in the range of 3-5 millimeters. The cells of such a product can have both square and rectangular shape, and the size of these elements can vary in the range of 50×50-200×200 millimeters.
Facade mesh
Its purpose is as a shelter scaffolding, and protecting them from various atmospheric phenomena, for example, precipitation, and adverse external influence. It also serves to prevent debris, power tools and various devices from falling from these structures. For the production of modern facade mesh, special light-stabilized polyethylene threads are used, characterized by extremely high strength.
Such products are made using the knotted weaving method - this avoids unraveling of the threads in the cut areas of the raw edges. Thanks to the use of the knotted knitting method, the material will not unravel in places where there is an accidental tear or cut. The outer edge of the mesh in most cases has special loops that allow it to be attached to scaffolding elements. The cells of the façade mesh are usually small in size.
Protective polyethylene sheets are characterized by good elasticity. They stretch easily, fully retaining their original strength characteristics. Facade mesh resistant to impact high temperatures and fading in the sun. Even at the production stage, this material is impregnated with a special protective substance that protects the product from possible destruction and rotting.
Plaster mesh
Today there are two types of plaster mesh:
1) metal;
2) fiberglass (plastic).
The main purpose of such products is to reinforce both plaster and many other types of wall coverings. Thanks to the presence of the plaster mesh, the strength of the coating significantly increases and ensures reliable protection surfaces from cracks and possible deformation of the walls is prevented.
Rabitz
Such a product is used for the purpose of reinforcing pipe products and walls, for the construction of various fences, sifting bulk materials and use as special fastening at mining sites.
Chain-link mesh differs in the shape of the cells (in the form of a square or diamond), the thickness of the wire used for its production and the dimensions of the cells. Such a product can be either coated with polyvinyl chloride or zinc, or without such a coating. Availability protective coating Together with the thickness of the wire, they largely determine the cost of the finished product.
By cutting and, which allows you to maintain the integrity and volume of its structure. PVA is an inexpensive type of mesh with good reinforcing properties. It is often used when laying heated floors.
The cells of such a mesh are diamond-shaped; the thickness of the PVA can be different. It is determined by the cutting step and the thickness of the metal.
Welded mesh
To make welded mesh, smooth wire is used, its rods are placed mutually perpendicular and welded by spot welding. This structure makes the mesh and products made from it rigid. The cells are square or rectangular in shape. The parameters of the cells and the type of grid are selected depending on the type of work for which it is intended.
When choosing a mesh, check the quality of welding - this main parameter her fortress. The weld must be able to withstand the bending load.
For plastering work, an uncoated mesh with cells measuring 12.5x12.5 mm, 12.5x25mm or 12.5x25mm and wire 0.6 and 1 mm thick is suitable.
When installing heated floors concrete screed reinforced with a mesh of uncoated wire 0.6-1 mm thick with cell sizes from 12.5x12.5 to 20x20 mm.
For fencing, a mesh made of thick wire with a galvanized or polymer coating is used. Product cells can be 50x50, 50x100, 100x100 mm.
Plaster mesh
In construction, plaster mesh is used to strengthen the layer of plaster inside and outside buildings, to insulate pipes and to filter bulk substances.
Metal plaster mesh is made from a sheet of metal into which diamond shapes are cut. They are then stretched into cells arranged in a checkerboard pattern.
In addition to metal plaster mesh Can be plastic or fiberglass. They are used for painting, plastering and facade work.
Wicker mesh
Wicker mesh or chain-link is widely used to create fences, build cages and enclosures for animals, for thermal insulation works. It is made from low-carbon steel by weaving flat spirals. The grid cells can be in the shape of a square or a diamond.
The highest quality chain link is polymer-coated. This mesh will last a very long time, as it is not subject to corrosion.
The strength of the chain-link depends on the mesh size and wire diameter. The larger the wire diameter and the smaller the mesh, the stronger the mesh.
