Mesh netting - a very common and versatile material for the construction of light railings, with low cost, high reliability and durability.
Its delivery is carried out in rolls of different sizes and heights. This form is very convenient for installing fences in a tensioned way.
Production of mesh netting
The mesh is made on machines by twisting a metal wire of a spiral shape. Plexus forms characteristic cells in the form of a square or rhombus. Due to such a cellular shape, the mesh has a characteristic elasticity for normal stiffness. With reliable fixation of the material, it is able to withstand mechanical stress, undergoing little stretching.
For weaving, a wire is used, the diameter of which is 1.5-5.5 mm.
Weaving is provided by machines of 2 types: manual and automatic.
- Manual machines are used for the independent manufacture of chain-links for their own needs. Due to the low productivity and rather low quality of the finished product, it is very difficult to organize production using such a machine. Most of them are home-made and used by the owners for their own needs. However, on the market you can also find factory-made hand-held machines.
- Automatic machines - with high productivity and fairly high quality of finished products. They are used for industrial production for commercial purposes. Such machines have great potential for setting up different types of weaving and cell sizes.
The main dimensions of the mesh-netting
In the form of cells, the grid is:
- square (grids with cells from 20 mm and more);
- rhombic (mesh with cells from 15 mm or more).
By surface type:
- galvanized wire mesh;
- without cover;
- PVC coated wire;
- made of galvanized wire with PVC coating in different colors.
The dimensions of the netting (height, width, diameter of its cells) are defined in GOST 5336-80. It is he who regulates the production of quality material.
The size of the mesh netting, as a rule, depends on its type. So, the material has a length of 10 m. The height is usually 1.5 m. These are the standard dimensions of the netting net. But you can meet this material and a height of 1.2 and even 3 meters.
Sometimes manufacturers, in order to meet their customers, produce non-standard rolls, the dimensions of which are 10-20 m long, the cells 10-20 mm long.
Application
A mesh netting is used, the price of which is indicated below, in everyday life and construction. A fence made of such material is very convenient and practical, for example, in cottages where the absence of shadow zones and ease of installation are appreciated.
Fine mesh is used in the manufacture of cages in poultry houses, rabbit houses and animal farms. Protective partitions are made of such a mesh at industrial enterprises; it is used during construction during the installation of bulk floors, for plaster reinforcement, and for reinforcing pipe insulation.
For plastering, reinforcing or other tasks where there is no direct contact of the material with the environment, a black uncoated mesh is used.
Wicker mesh is also used for fencing tennis courts, sports grounds, sifting materials, fixing mine workings in mines and mines, fastening earthen slopes.
Aesthetic mesh made of wire with different coatings. Galvanized mesh netting is widespread. It is aesthetic, less susceptible to corrosion, while it is sold at an affordable price. Nets made from galvanized wire can last three times longer than non-galvanized nets.
Choosing certain sizes of mesh-netting, it is necessary to really assess how appropriate and beneficial it is to use a material with certain characteristics.
Corrosion Protection
Due to the fact that weaving the mesh is made of thin wire, the issue of corrosion protection of this material is very relevant. Different types of this material have a different protective coating that prevents rust. More often the grid is made of galvanized steel. When applying zinc coating with hot galvanization, the material lasts up to 20 years. Cold or galvanized galvanization provides less durable protection.
The galvanized mesh can be coated with a polymer coating. Such material lasts longer and has a neat, attractive appearance.
Almost everywhere, the chain-link is covered with polyvinyl chloride. Qualitatively applied PVC coating provides resistance to atmospheric influences and aggressive environmental components. With such a coating, the material reliably lasts up to 50 years if the polymer is not destroyed. The polymer coated mesh provides decorative properties. It contains dye, so you can select any color for the fence, and there are many options.
Advantages of fencing from the netting
This material has many advantages. First of all, this is the optimal price, which is much less than the cost of other materials. However, this is not the only plus. Also among the advantages include:
- The transmission of sunlight and air flow, without shading the area, while providing natural ventilation. In addition, sites with a similar fence are perfectly visible.
- Such a fence is very quick and easy to install, while there is no need to use special equipment or hire professional craftsmen.
- Mesh netting, the price of which is low, is a light but durable material. Fences made of this material perform their main function - they are able to prevent unauthorized persons from entering the enclosed areas.
Cost
Mesh netting is a very convenient and inexpensive building material, the scope of which is quite extensive. Due to huge demand, there are many organizations that produce it. The cost for all is different and depends on the capabilities of the equipment of the manufacturer and the polymers used. In addition, the larger the cell size, the cheaper the netting, since it takes less material to make it, thereby reducing the cost.
We propose to consider an approximate state of affairs.
So, a roll of mesh netting from raw steel wire, with classic parameters, 1.5 m high, a 500 mm cell costs 550-650 rubles. per 10 meter roll. A galvanized wire mesh having the same parameters costs the same. The price of this polymer coated material is approximately 1500-2000 rubles. per roll 10 m.
