The weight of the grid is 50х50х3. Metal mesh netting: weight. Dimensions of metal mesh

At large volumes of delivery of building materials it is necessary to know also the weight of the net of the slab, and not only its main characteristics: the thickness of the wire, the dimensions of the cells and rolls. If Rabitza is made in full accordance with GOST, then its mass of 1 m 2 can be found in it or in the directory. And when the manufacturer makes a non-standard grid, its weight will have to be calculated.

This woven mesh is produced according to the standard 5336-80. At the end of this GOST there is a reference application, in the table of which the masses of 1 m 2 of all produced according to it are indicated. These data are presented in the table below.

Note. The values ​​referring to products with square cells are indicated in parentheses.

Standard grid-Rabitz is produced only with square cells

As can be seen from the table, the weight of the 50x50 mesh netting is 2.42 kg per 1 m 2. And in the standard version, these products are produced only with square cells and a wire with a diameter of 3 mm

Manufacturers of Rabitz can, at their own discretion or the request of the customer, produce it with characteristics that differ from those indicated in the table above. This may be the following deviations from the parameters regulated by the standard 5336:

1. The thickness of the wire used for making the wire does not correspond to the established standard. For example, rabitsa with the number of the cell 15 according to GOST 5336 should be made of wire with a diameter of 2 mm. And the manufacturer can make this wire mesh from a wire with a different thickness.
2. The shape of the grid cells does not correspond to the established standard. For example, a rabitsa with the size of the side of cell 5 according to GOST 5336 should be made only rhombic. And the manufacturer can make it with square cells.

Of course, in order to figure out the weight of 1 m 2 of such non-standard grids, it's best to weigh 1 roll of them, and then make a calculation. That is, divide the balance readings (total weight of the roll) into its area. In this way, the most accurate value of the weight of 1 m 2 of the wire produced with any of the above deviations from GOST will be obtained. The total area of ​​the roll, as everyone remembers, is calculated by multiplying its width by the length. If you can not weigh the non-standard grid for any reason, use the following methods of approximate calculation-correction of standard values ​​of mass.

For a grid with non-standard cells, there is a correction factor

If the thickness of the wire used does not comply with the standard 5336, the calculation sequence is as follows. First, divide the standard diameter for the given cell number (see the above or table GOST 5336) for the diameter of the wire from which the mesh is actually made. The resulting coefficient is squared, that is, we multiply ourselves by ourselves. And then we divide by the obtained result the mass of 1 m 2 indicated in the GOST, for a grid with the given cell number and the standard diameter of the wire.

If the mesh does not correspond to the standard form of cells, then we need only use the approximate correction factor equal to 1.12. And, when instead of square at a grid rhombic cells, it is necessary to specify mass in GOST 1 m 2 for a product with the given number of a cell and standard diameter of a wire to multiply by 1.12. And when instead of rhombic square - on the contrary, divided by 1.12. The resulting value and will be a mass of 1 m 2 of such a non-standard grid. And when the rabitsa differs from the standard and in the shape of the cells, and the diameter of the wire, perform both of the above calculations. The sequence does not matter.

Only with the second in the sequence of calculations, we are correcting not the table value of the mass of 1 m 2 from GOST, but calculated in the process of the first correction.

To determine how much it will weigh, it is best to weigh it. This will give the most accurate result. But you can calculate. The easiest way to do this is for standard grids. We take from the above or table GOST 5336 a mass of 1 m 2 and multiply it by the area of ​​the roll (this is the length multiplied by the width).

To find out the weight of a 1 m grid, it is best to weigh the roll

If it is necessary to calculate the weight of a roll of mesh netting produced with deviations from the standard, then first you have to make a calculation-correction of the mass of 1 m 2. The method is given in the previous chapter. We hope, now you understand how to calculate the weight of the roll and square. meter. Successful calculations!

Understand its weight, overall and some specific dimensions, namely: the height, width and length of the mesh, the diameter of the wire used, the dimensions of the cells. All these values ​​are determined by GOST 5336-80, which regulates its production.

Dimensions of metal mesh

The dimensions of the Rabitz grid are usually standard. Its linear length in a typical roll is 10 meters, and the height of the rabbit is 1.5 meters. However, the manufacturers of the mesh size at the request of the customer can change by releasing non-standard rolls. In them, it can have a length of up to 20 meters, and height - from one to three meters.

The standard grid cell grid has a square or rhombic shape. As a rule, their size (diameter) starts from 10x10 and can reach up to 200x200. The diameter of the wire for the grid depends on the size of the webs and is 1-2 millimeters. For its production, use both ordinary (steel) wire and galvanized, the coating of which increases the weight of the mesh netting in a roll.

Metal mesh netting: weight

The need to determine the value of the weight of the netting grid arises when choosing the carrying capacity of vehicles and the vehicle itself, which is necessary for its transportation.

The weight of the net is not regulated by anything and depends on the type of wire used plus the dimensions of the webs - the more their dimensions and the thickness of the wire, the greater the weight of the net.

To correctly determine the weight of the grid, it is necessary to understand its labeling. Suppose the roll of the net of the mesh is marked as follows: R-15-1 GOST 5336-80. This means that this mesh netting is braided, with a rhombic-shaped cell number 15. For its production, a thermally untreated wire with a diameter of 1.0 mm and having no zinc coating is used.

When using galvanized wire, in the marking before GOST, an uppercase letter "O" is added. If the letter "P" (rhombic) is absent before the size of the grid cell, this means that a square cell is used in the manufacture of the rabbit. The presence in the marking of the capital letter "K" corresponds to the net of compact compacting.

Table for calculating the grid dimensions

There is a special table for the weight of the mesh netting, with which you can check the length of the roll, the dimensions of the cell and the diameter of the wire in a roll. Multiplying the width of the mesh by the length of the roll and by the theoretical weight of 1 meter square mesh, you can determine the actual weight of the entire roll. It should not differ more than ± 5% from the theoretical one. After all, the greater the weight of the mesh net, the higher its strength and price. That is, these two values ​​are interrelated.
