Welded mesh fences: advantages and disadvantages

Currently, the building materials market is saturated with an impressive variety of goods for various purposes, fences are no exception. In addition to the main function - the protection of private home ownership, these designs also perform an aesthetic role, where an important place is occupied by the production material of fences. It makes sense to understand in more detail what fences from a welded mesh are.

A welded mesh fence is a variety of metal sections mounted on vertical posts, the basis of which is a steel mesh with a certain size of holes. The elements are fastened together by spot welding, which provides a fairly strong connection. Reliable connecting rods act as auxiliary stiffening ribs.

Such constructions are installed in order to ensure the protection of a private territory,but current trends require maximum capacity to create the original design of the estate, including the landscape and exterior of buildings. Additional details that can be used in the manufacture of sections, will help to diversify the metal fence and give the individuality of the design.

Fences are popular not only in everyday life, they are often installed in public places and at enterprises.

In some places, welded mesh fences are simply necessary. These areas include:

• sports grounds;
• industrial facilities and enterprises requiring the creation of protective fences with enhanced security: railway stations, gas and electric substations, a package transformer substation, a gas station;
• the territory of schools, parks, supermarkets, and other public institutions.

These fences are also used as:

• restrictive grids for forest areas and agricultural needs;
• universal barriers for private country sites, cottages, parking of various types of transport;
• decorative fences;
• metal constructions for greenhouses, pets enclosures;

Metal fencing systems of welded mesh retain their original appearance for a long period of operation. Installation work is quick and easy. Material differs in the absolute environmental friendliness, the improved anticorrosive properties, does not demand special leaving. Mesh cells can be of various sizes.

In addition, the welded mesh fence has the following advantages:

• mesh stiffness avoids sagging and bending;
• color palette is presented in a wide range;
• the design is lightweight, contributes to the normal circulation of air flow and the penetration of light without creating a shadow.

The disadvantages of such fences is considered excessive visibility of the territory. In spring and summer, greenery around the perimeter will help to correct the situation.

Since ancient times, metal products have been used in construction, and nowadays various decorative elements made of this material are in great demand.In modern production, steel mesh for the manufacture of designer intake systems is treated with a special compound, which significantly improves the technical characteristics and increases its operating period.

Based on the coating of the material used, welded mesh for fences are:

• non-galvanized - the most budget option that requires painting after installation;
• galvanized - quite durable, resistant to weathering;
• with a polymer coating - the grid, additionally protected from weather conditions and mechanical damage, is represented mainly in green;
• galvanized and coated with polymer mass - the most expensive option, but also the most durable;
• from stainless steel.

Protective structures are classified not only by metal coating, but also by the method of installation. According to this attribute, they are divided into two main types.

Such fences are installed using special racks, between which the welded mesh, produced in rolls, is stretched. A characteristic feature of the roll mesh is a relatively small diameter of the wire, which allows you to twist the product into a roll.

Installation of this design is the most expensive than simple stretching work, but with all this sectional systems of welded mesh are the most popular options.

Components for such fences are issued in maps or gitterah, which are welded sections with certain comparable dimensions, length and width. Such fencing is made of thick rods and can not be rolled.

Choosing a fence of welded mesh, quite often there is an important question related to the type of coating. Currently, in the manufacture of roll nets for fences, as a rule, galvanized or non-galvanized mesh is used. For panel or sectional welded structures made of mesh, PPL and PVC coatings are used:

• PPL coating or powder paint without the use of liquid solvents. The coating has a reliable and high-quality adhesion to the metal due to the special technology of application and baking. PPL is deservedly called anti-vandal remedy, the paint is not afraid of external negative influences and temperature changes. The disadvantages include a low level of elasticity, which does not allow to cover products in rolls. Therefore, PPL paint only ready sections.

• PVC Coating (polymer mass) has much less advantages. If the elasticity of the paint exceeds powder coating, then resistance to negative factors leaves much to be desired. The technology of applying a polymer coating causes a rather high cost of products.

When choosing products you should pay attention to some factors:

• quality of welds;
• no deviations in the wire section;
• mesh strength, the ability to withstand excesses;
• availability of quality certificate.

Depending on the purpose of the protective structure, it is worthwhile to follow certain rules when choosing:

• for the fence on private sites, it is desirable to use a grid with a height of 1.25 - 2.05 m with a wire thickness of 4-4.5 mm.
• In industrial areas, the use of nets with a height of 2.05 to 2.25 m and a wire thickness of 4.5 to 5.5 mm is recommended.
• For children's playgrounds, as well as public areas, fences are used with nets 1.25-2.25 m high, with a rod thickness of 4-5.5 mm.
• The smaller the cells and the greater the thickness of the rod, the more stable and stronger the design itself.

But still you should be familiar with the installation sequence of this type of fence. The stages of mounting tension guards are:

• Determination of the fence line, marking, including the location of the supports.
• Digging holes out of the desired depth in the designated areas.
• Installation of supports and pouring the base with concrete.
• Tension of a rolled grid between support. It is carried out after hardening of concrete, starting from the angle of the fence. The net is attached to the posts with collars, as a result of which integrity of the fence is achieved.

When installing sectional fences, you need to take into account the slight difference from the above steps. It consists in the acquisition of special corners, which will help to create a strong frame. From these elements, a rectangular section is welded, onto which the welded section is then fixed.

There are several subtleties of installing fences that you should know:

• metal poles are best used as supports;
• roll grid before use must be deployed and left for 1-2 days;
• cement mortar is best prepared on the basis of one pillar;
• installation work will be better done in spring, when the earth is already loose.

Metal fences are varied. Fences of welded mesh according to basic criteria are no worse than stone or brick fences. The production uses high-quality steel alloys, providing a high level of reliability, strength and durability. It’s necessary to choose them taking into account the functions and principles of design of the site, focusing on products of famous manufacturers.

The Belgian company is popular in the global market. "Bekaert", which has for a long time been supplying quality welded wire fence systems. Domestic manufacturers offer products at a lower price, but perfect quality, reliability and durability remain with Bekaert.

Russian TM "Cascade" specializes in the production of materials for this type of fencing. Galvanized rolled mesh of domestic production allows you to build fences in industrial plants, on summer cottages, on the banks of reservoirs.

The choice of welded mesh fencing is the right solution, providing multifunctionality, namely, reliable protection while maintaining the option of viewing and penetrating the sun's rays throughout the fenced area.

Currently, such fences are very popular mainly in the West, but they have already begun to spread rapidly in the CIS.
