Zaporozhye expanded metal sheet PVL, stainless steel PVL sheet, black (steel), galvanized from availability and production

Expanded metal sheet, which is abbreviated as PVL, is a metal product, the surface of which consists of evenly spaced and absolutely identical cells.
Basically, you can find an abbreviated designation, but a full transcript is often used. Most often, PVL is used in construction, and is also actively used for the manufacture of decking, various kinds of fences and transitions.
This is because cross-drawn sheets have a rather low mass, but at the same time they are distinguished by a high degree of strength and rigidity.
PVL has a number of advantages that make it a truly versatile material.

     As mentioned earlier, among the undeniable advantages of such raw materials is high strength. Many may doubt this, since the holes in the material are quite large, but due to the symmetry of their arrangement, the tension of the material is balanced, and the likelihood of serious deformation is reduced to zero.
     The material is resistant to corrosion, since high-quality metal alloys are used for its production. For example, expanded steel sheet can last for many years and even decades. This material is not afraid of sudden changes in temperature, so there are no territorial restrictions on use.
     The presence of cells allows to reduce the weight of each sheet by about 80% (depending on the metals used in the alloy). It is this factor that simplifies not only operating conditions, but also transportation and installation features. In the manufacture of hinged structures, lightweight materials are most in demand, since they reduce pressure, and hence the risk of collapse.
     PVL does not need any special care or cleaning. Thanks to the cells, liquid and small debris do not accumulate on the surface of the sheets, which also affects the appearance of rust and any damage. It can also be noted that any types of waste do not stick to the surface of the material, which means that they can be easily removed.

As for the period of snowfall, the issue can be solved quite easily - with the help of an ordinary brush.
Expanded metal sheets: what is it and where are they used Expanded metal sheets: what is it and where are they used
As previously mentioned, non-alloy steels and aluminum compositions that are resistant to corrosion are used for the manufacture of expanded metal sheets.
Also, various non-ferrous metals and other alloys based on them are often used. The most common and reliable option is carbon steel sheets with any degree of oxidation.
As for the dimensions, you should know that the parameters of each are provided for by GOST 8706-78.
The manufacturing process of expanded metal sheets has some features and consists of several stages. Let's consider each of them in more detail.

     Initially, sheet steel does not have any holes and cells on the surface. Notches are applied using a special automatic knife, which is programmed for the required dimensions, shape, and location. So, holes can resemble in shape a geometric figure of a rhombus or large fish scales.
     Then the material must be stretched in such a way that the perforated holes acquire the necessary - specified by the standards - dimensions.
     Next, the resulting sample must be rolled along the long edge of the notches, thereby making it flatter. In addition, these manipulations will help increase the degree of resistance of the sheet to various kinds of deformations.
  Expanded-drawn sheets have many undeniable advantages:

     Metal product with high strength. The cells are quite large, but they are arranged symmetrically, so the tension of the material is even, there is no risk of serious deformation.
     For all their strength, PVL weighs a little. The presence of cells reduces the weight by about 80%. It is quite easy to transport, carry, mount, there is less risk of collapse and windage even in strong winds.
     Serves for years, decades, is not afraid of temperature changes.
     No need to clean and maintain, small debris does not accumulate on such a cellular surface. Adhering snow is simply cleaned with a broom or brush.

In private construction, expanded metal sheets are widely used for arranging steps, including on a metal porch, outdoor stairs, for example, to the attic. Light weight and strength make PVL an ideal material for stair structures. In addition, the cellular steps are completely non-slippery, safe, and debris does not linger on them.
They also make railings for balconies and terraces from PVC. In addition, such sheets can be used to build a podium for a portable pool, build an observation deck, bridge, flooring, use it to reinforce the foundation, strengthen other concrete structures. Build from expanded metal sheets and fences. They are stronger, more durable and look more attractive.
To give PVL a more aestheticth type of metal can be painted. Sheets are sold by weight, the average price varies depending on the world metal prices. Affordable, strong, durable material that is in demand among homeowners.
A rolled metal sheet that has been tested for compliance with the standards for the thickness and quality of the metal, compliance with the declared grade is allowed for production. The characteristic of rolled products must completely exclude mechanical damage, the presence of scale and rust.
The rolled metal sheet is covered with a die-cut notch and then evenly stretched until a characteristic geometric pattern appears. Then the sheet is beaten and leveled in accordance with the accepted GOST 8706. When the slotted sheet is pulled out, the strips turn at an angle and strength ribs are formed. The PVL sheet perfectly holds the load, which contributes to significant metal savings and a decrease in the total weight of metal structures. Saving metal when using PVL can reach up to 80% while maintaining the strength and stability of the structure.
The characteristics of the patterns are indicated by the letters:

     TR - expanded metal with a classic rhomboid cell pattern
     TQ - rectangular or square notch
     TE - round and oval cutting. Rolled metal is drawn with the formation of rounded cells on specialized equipment.
     TH - hexagonal
     TD - with a decorative die-cut pattern.

The characteristic and size of the pattern corresponds to GOST in terms of the thickness of rolled metal and purpose.

     In accordance with GOST, the width of the canvas is 500, 600, 700, 800, 900, 1000 and 1250 mm. The size in length according to GOST is up to 3.5 meters.
     GOST also determines the size and location of the cells. The limiting deviations of the geometry are no more than 10 mm in width and no more than 25 mm in the measured length.
     When stretching, the size of allowable stress cracks is no more than 2 mm.
     With custom dimensions, it is possible to manufacture a part of the rolling area without notches, if this is due to the project documentation or installation requirements.
     The standard, most commonly used sheet size used for mounting is 1250 mm by 2000 mm.
