All about construction mesh

Construction mesh is a popular material with a wide range of uses... The material in this article will tell you about its features, varieties and dimensions. In addition, we will show you what to look for when buying the required option.

Construction mesh - reinforcing material with different durability resource... It does not allow the formation of cracks, deformation and stretching of the treated ceilings, makes it difficult to destroy them during operation. In addition to reinforcement, the mesh also has a protective function; it is used when carrying out high-rise work.

Mesh fences of this type are in demand from developers for the reason:

• low cost;
• ease of loading and transportation;
• safe components;
• variety of shades, sizes, configurations;
• ease of washing;
• practicality, reusability.

Construction mesh is sold in rolls and is subject to government regulations. It is used in the reconstruction of buildings, in the repair of road surfaces, telecommunications. It is indispensable in the care of lawns, sowing, and is used to decorate the space.

By the type of production, it can be welded, woven, expanded metal. According to the coating method, it may or may not have a layer of protection. In addition, both the size and geometry of the material cells vary. They can be square, hexagonal, diamond-shaped.

In the production of building nets, different raw materials are used (metal, basalt, fiberglass). The material type determines the properties of the finished product.

Metal construction mesh is used for working with universal and thick working mortars (up to 3 cm thick). The thicker it is, the larger its cells and more weight. The galvanized version differs from the usual variety in resistance to corrosion and decay.

Basalt construction mesh is a reliable and durable material that is resistant to external influences. In comparison with the iron analogue, it is chemically inert and does not react with the working solutions used. The material makes the mesh flexible, it weighs little.

It improves load-carrying properties and vibration resistance. It has a 30% safety margin, is heat-resistant, has low hygroscopicity.

Plastic construction mesh has high performance properties. It improves the strength of the masonry, is not suitable for working with thick coatings, and has a smaller mesh size compared to the metal varieties. It cannot withstand a large weight of working solutions, it can be destroyed in the process of contact with alkali.

Composite fiberglass mesh has many advantages, which explains its popularity in the construction industry. It can be used for mounting on any surface. It is resistant to alkali and chemical solvents. Durable, strong, resistant to deformation and thermal expansion.

Net from fiberglass does not imply reinforcement of heavy materials.It is woven on a special machine, after which it is impregnated with a special alkali-resistant composition. They buy it to protect premises from insects, take it for plastering surfaces, carrying out restoration work to restore plaster.

The market for building nets is very diverse: there are self-adhesive, reinforced, mounting, shading, covering, coordinate, camouflage nets on sale. At the same time, the varieties are not only simple, monochromatic - today you can pick up options with a pattern of different themes.

The entire product range can be classified according to the type of purpose. Each variety has its own characteristics.

The main purpose of the facade construction mesh is protection of external finishing works from adverse environmental conditions and various physical influences. It is bought to protect against falling building materials and tools.

Made from plastic / polyethylene tape-type yarns with knotted weaving. Thanks to this, it is strong, elastic, reliable, does not bloom after cutting and damage.

Available in rolls of different colors. It happens green, black, yellow, blue, white, gray. The green network is bought to protect forests, to prevent the fall of construction debris. Material of other shades is used for finishing work. Facade mesh is easy to use, reusable and can stretch up to 15% of its own length.

It is not exposed to rust, temperature extremes, moisture, and is not toxic to humans and the environment.... Creates a safe working environment for workers. Differs in the presence of special loops on the outer edge, provided for fastening. Has small mesh sizes.

Masonry construction mesh is a reinforcing element of construction. It is made of wire with a diameter of 3-5 mm and metal, welding structural elements at right angles. The wire used is covered with a PVC protection layer. The material is taken to level the base and strengthen it.

The parameters of the cells can be small, standard, large, designed for rough cement slurries of great thickness (from 5 to 20 cm one side). It is a reinforcing material for walls and floor screed, preventing deformation of surfaces during shrinkage and drying... It helps to maintain the bearing capacity of buildings.

The masonry mesh is an alternative to the previously used welded type iron bars. It is resistant to moisture, durable. In addition to masonry, road and plastering works, it is used when pouring foundations, fastening mine developments. Differs in a small price, it is galvanized.

This type is metal and fiberglass (made of plastic, polyurethane). It is most often used for reinforcing wall surfaces made of various materials. Increases their strength, provides reliable protection against cracks and deformations.

Differs in the variability of the size range: it happens with a small and large cell... Depending on this, it is used for reinforcing mortars of different thicknesses.

It has a small and medium weight, it is used for indoor and outdoor work. Some varieties have special reinforced nodes. Plastering construction mesh is capable of withstanding significant weight loads. Depending on the variety, it can be used in the decoration of ceilings. It is used in the production of self-leveling floors, sound and heat insulation, tile cladding.

The protective catching mesh is called "ZUS". It is used to protect construction workers from falling from a height. It is used in the construction of civil and commercial buildings. Perfectly protects workers working at height and below, supporting a total weight of up to 100 kg.

Differs in strength, reliability, the ability to install on any floor of the building... Assumes repeated use, transfer and installation elsewhere. It is durable, made of especially durable artificial materials. It is used not only for temporary, but also permanent fixation on the walls of houses with a height of 6-7 m.

It means fixing to a special metal frame, installed by means of supports (attached to scaffolding or to the walls of houses). Protects people from icicles falling from roofs.

This construction mesh is used as a temporary barrier type. For example, it is bought for fencing construction sites, hazardous areas in which work is carried out. It is used for fencing road repair areas, sports events.

Signal fences are used by employees of the Ministry of Emergency Situations, indicating with their help the territories affected by natural disasters. This is a bright orange mesh (often with a fluorescent effect). It is noticeable in the dark, is characterized by low weight, great strength and flexibility.

It is durable, easy to load, transport and store. Does not rust and decay. It can withstand a temperature range from +50 to -40 degrees. Manufactured by extrusion with a selection of unique polymers that improve the mechanical characteristics of the material.

The chain-link refers to the mesh of the enclosing type. It is made of plastic, metal, has an ideal price-quality ratio. It is used for fencing private households. It is considered easy to install, it is used as the basis of a green hedge. Its strength depends on the size of the cells and the thickness of the material used.

It is in demand in agriculture and animal husbandry. It is used to make safe and resilient pens for livestock and poultry. The plasticized mesh can have different colors; it is used to decorate social events, delimiting the space into separate zones. It can be produced in red, blue, white, yellow, green.

Easily assembled and dismantled, transferred to a new location. Can be non-galvanized, galvanized, coated with a polymer layer. The first type involves painting immediately after installation.

The parameters of the cellular material vary depending on the scope of use and the type of material selected. For example, the cells of the masonry mesh can have dimensions of 50x50, 100x100, 200x200 mm. The smallest parameters are 2.5 and 3.5 mm.

Plaster analogs made of plastic, with a small cell, have parameters of 5x5 mm, they are used to work with thin layers of plaster. The universal dimensions of the fine mesh polyurethane plaster mesh are 6x6 mm. Plaster is reinforced with such a building material during the cladding of walls and ceilings.

Versatile options with a medium-sized cell are 13x15 mm. Large cells are 22x35 mm in size. Large rooms (for example, warehouses, production facades) are trimmed with such nets.

Polypropylene construction nets from other manufacturers may have other mesh sizes (5x6, 12x15, 12x14 mm). The parameters of the cells of the emergency signal grid are different: 45x90, 45x45 mm.

When choosing the best option for a building mesh, it is necessary to take into account its suitability for solving a specific task... In addition, you need to take into account the features of the selected material from which the product is made.

For example, when choosing a fiberglass variety, to determine the quality, it is crumpled in a fist. If it quickly returns to its original form, the item is worth buying. If there is deformation, it is worth looking for the product from another seller.

You need to pay attention to the quality of the weave. The cells must be identical in size and shape. It is important to pay attention to the thickness of the material, the volume of the roll, the dimension of the cells. Each type of surface needs a specific type of mesh.

For example, for finishing the ceiling, you need a light variety with a small cell size. Its average density varies between 50-60 g / m2.

The mesh can be from 2.5 to 3.5 mm. For facade and roofing work, a variety with a density index of 130-180 g / m2 is needed. You can buy fiberglass mesh with 5x5 mm meshes.

When choosing any option, you need to pay attention to the reputation of the manufacturer. Some unscrupulous sellers try to sell products without the necessary impregnating composition. To eliminate the risk of buying a bad product, you need to require appropriate documentation confirming the quality of the mesh.

It is important to consider the basic requirements for the construction mesh. For example, it should be accompanied by documentation of tests carried out by an independent laboratory. In addition, you need to take the option with the optimal density, corrosion-resistant, and lightweight. The product should not complicate the system of building loads.

The mesh must be resistant to stretching with acceptable flexibility... Leading manufacturers of building nets can sell products along with an adhesive for securing them. The length of the rolls varies from 30 to 80 m, the width is 1 m. The weight can be up to 80 kg (depending on the mesh material, thickness and footage).
