Mesh for cutting off concrete; woven metal

The mesh for cutting off concrete is a durable metal sheet made by weaving steel wires together with square-shaped cells. The wire can be of different sections, as well as the size of the cells. Most often, such a woven mesh is used when carrying out repair and construction work in order to strengthen the solution during the hardening process, if it is possible to allow excess water to pass through.

The cut-off mesh for concrete demonstrates excellent performance characteristics, is strong and reliable, flexible (which allows it to be used to create reinforced concrete of complex shapes), is sold at an affordable price, and has found application in a wide variety of types of work. This universal structural product is used when performing plastering work, for strengthening (reinforcement), sifting bulk building materials, effective filtration of dispersion mixtures, etc.

But the main purpose of the mesh is to be used in various types of concrete work. Due to the strength of the mesh, it is successfully used to strengthen vertical permanent formwork. Due to the presence of small cells, excess moisture from the solution is well removed through the mesh, and the concrete is held securely, which significantly increases its strength.

The use of cutoff is especially important when performing concrete work on large-scale areas. Once the boundaries of the grips have been determined, the mesh is mounted vertically and held in place by ribs made of reinforcement or boards. It is sometimes impossible to do without such a mesh when implementing different types of concrete work, but before use it is advisable to study all the types, features, and nuances of installation.

Woven metal mesh for cutting off concrete: application and types

The main types of mesh for cutting off concrete:

Types of meshes by purpose:

Expanded – for filtering/screening building materials.
Plastering – for performing plastering and facade work.

Types of mesh by weaving method:

By type, the mesh can be partially corrugated (rigid, wavy in the longitudinal part), smooth without bulges or bends, filter (when the cells are not visible), and also conveyor, which is made from thin wires twisted into ropes.

mm – the optimal choice in terms of cost and technical properties. When sifting, square cells with a side of 5 millimeters allow granots to pass through, but retain larger crushed stone and pebbles. This is necessary when constructing thin structures and decorative landscape design figures. Also in other cases when a fairly homogeneous material is required. There are practically no defects in the woven base. This ensures high quality of the output mixture. Wire 0.7 mm thick with frequent weaves can withstand relatively strong pressure, which allows you to quickly sift out significant quantities of gravel, pouring in large portions.

The main application of mesh is for concrete reinforcement

Woven mesh for cutting off concrete

designed to strengthen the mortar by releasing excess water during hardening. Due to its high viscosity, the semi-solid solidifying mass remains in a limited space, only excess liquid comes out. Solid components are completely preserved and solidify at the best ratio with the liquid phase.

In monolithic construction, galvanized mesh is usually used to pour concrete.

.
Galvanization eliminates premature corrosion in an alkaline environment, which is created by lime and components of Portland cement. For thick reinforcement bars, the corrosion effect is insignificant, but for thin wire, the mesh for concrete screed
protects to a significant extent.

Non-galvanized woven mesh for concrete

suitable for structures experiencing light loads or when using building materials with an acidic reaction (gypsum-based mixtures).
This is an inexpensive, practical material in demand in low-rise construction, garden and park architecture. When strengthening asphalt pavement, carbon steel is also suitable, since petroleum products protect the ferrous metal from corrosion. In the most critical areas,

Thus, when carrying out external work, when contact with an aggressive external environment is inevitable, it is necessary to use galvanized or stainless steel mesh (due to the high cost of stainless steel, the use of these mesh for construction purposes is small).

Woven metal mesh is supplied in rolls and is characterized by the size of the clear side of the cell, the diameter of the wire and the dimensions of the rolls. Possible values:

Cell side size

Wire diameter (D)

Depending on the cell size, wire diameter and type of mesh coating, the scope of its application depends. Woven mesh is used in construction, as well as for industrial needs and in agriculture.

In industry, such meshes are used in the production of conveyor belts, sorting of abrasives, and filtration of liquids.

In agriculture, such meshes are used for drying grain, filtering oils, and sifting various granular and bulk products.

Use of woven metal mesh in construction

This mesh is used to reinforce larger forms - cornices, capitals, profiles and other plaster products.

The main advantages of woven mesh for

using them for construction purposes

Due to the use of annealed wire, the mesh is soft and does not spring - therefore, after bending and deformation, it remains in this position and completely follows the shape of the surface being treated.

Good adhesion to any mortar (cement, gypsum, lime).

A large selection of standard sizes produced in terms of cell sizes and wire diameters. There is always the opportunity to choose the right option.

Ease of attaching the mesh to various surfaces (wood, concrete, metal, etc.).

Cell sizes and wire thickness used in meshes

According to GOST, the diameter of the wire for weaving a mesh should be a minimum of 0.03 and a maximum of 3 millimeters. The shape of the cells can be square or rectangular, which depends only on the method of weaving the wire. The network can be made with or without closures so that the outer wires do not fall out.

The cut-off network must be free of any deformations and cuts; bending at the beginning of the piece and loop is allowed, the optimal number of which is a maximum of two per square meter. Woven mesh is sold in the form of rolls, at different prices, which depend on the type of wire and the width of the cells.

You can buy mesh at any hardware store (in Moscow and the regions). Before purchasing, it is important to decide what work you plan to perform with its help - filtration of liquids/gases, cladding or plastering, creating a fence or ventilation grill, cage or enclosure.

Steel mesh perfectly strengthens concrete, preventing it from crumbling. Before installing the mesh, it must be cleaned of corrosion and contamination. The product efficiently seals and protects self-leveling concrete floors, brickwork, screed under heated floors, asphalt layers, ramps/steps, curb stones, etc. from cracks.

Scope of use of the cut-off mesh:

Finishing plastering work - mesh significantly extends the service life of buildings, increases adhesion between the base and plaster, and prevents surfaces from becoming cracked. Typically, meshes are used when applying a thick layer of mortar, as well as for finishing surfaces with poor adhesion.
Laying concrete - the mesh increases strength, distributes the weight evenly over a large area, is used for laying asphalt sheets, in the production of ramps and steps.
Floor screed - eliminates the risk of cracks and increases strength. Often, meshes are used to create screeds with foam-insulated floors.
Masonry of houses made of porous/light materials.
Filling large areas with concrete - here the mesh becomes permanent formwork.
Sifting of bulk materials, filtration of dispersed mixtures.

Cut-off mesh

The phrase cut-off mesh usually means woven mesh 5x5x0.7 mm GOST 3826. This mesh got its name due to its use in monolithic construction.

the mesh remains in the concrete layer, which also eliminates the need to dismantle part of the formwork.

Currently, other sizes of woven mesh are used for cutting off concrete.

woven mesh 2x2x0.4

woven mesh 3.2x3.2x0.5

woven mesh 5x5x1.2

also for cutoff, the TsPVS mesh can be used to a limited extent.

Kinds

For the production of woven mesh, wire is used, which can be either stainless, galvanized, or ordinary. This is determined by Gosstandart 3826-82. It is better to use stainless steel because it repels corrosion, which is important in some applications. It is divided into several types:

woven metal mesh, which is made low carbon, heat treated and coated, or not. It comes with both square and rectangular cells;
wire - an interlacing of wires that are located perpendicular to each other;
galvanized woven – galvanized mesh, used for cladding, laying tiles, etc. Rolls weighing no more than 500 kg are available for sale;
stainless – found application in construction, as well as in mechanical engineering and the oil and gas industry.
