Expanded stainless steel sheet 42х12 mm 2,0х1000x2000 mm is a solid metal mesh made from steel sheet by punching and drawing. This technology makes it possible to obtain a strong and light mesh, which is on average 80% lighter than a solid steel sheet of similar dimensions. In addition, the process makes it possible to minimize surface texture, as well as increase resistance to deformation. At the same time, a competent approach to the manufacture of the mesh retains excellent indicators of its rigidity.
Such a sheet is made from various types of steel:
The standard dimensions of the product are from 1 to 6 millimeters in thickness, from 1250 millimeters in width and from 1900 millimeters in length.
Such a sheet is made from various types of stamps:
AISI304
AISI321
AISI316L
AISI310S
AISI430
Expanded stainless steel sheet is produced with the following hole shapes: rhombic, square, round, hexagonal and decorative. The production of expanded metal is non-waste, therefore the price of this material is cheaper compared to similar materials.
Expanded stainless steel sheet is one of the modern materials used mainly in architecture and construction. Used in the design of exclusive interiors and exteriors. Products made from this type of sheet can also be used in the engineering industry, agriculture and other industries as gratings, casings, filter screens, decking, etc.
Expanded metal sheet is a metal sheet that is produced by punching holes of the required shape and subsequently stretched to the desired size. In general, PVL is 80% lighter than a solid sheet, which increases the percentage of efficiency and the possibility of its use in a wider format range of metal structures. In addition, the cost of PVL is lower than the cost of a solid sheet of the same area, which reduces material costs for solving the same type of construction tasks.
Expanded stainless steel sheet is made from a stainless steel sheet or a roll, depending on the required size, and the final product does not differ in strength from the workpiece.
In addition to the relative budget and a pleasant aesthetic design, the “notch” also has such a useful quality as self-cleaning and anti-slip. That is why not only external and internal floorings and steps are increasingly made of this material, but also the structures are larger and used in more difficult operating conditions.
Scope of expanded metal sheet
Perforated sheets are used both in industrial and "civil" construction. The wide scope of application is due to the relatively low cost and high strength, as well as the lightness of the structures that consist of such sheets.
Expanded metal excels as decking for loading docks and crane platforms, and looks good as sidewalk and walkway decking in shopping malls and industrial shops. Recently, this type of material has often been used as skylights and decorative elements in fences, as stairs and even protective grilles on windows. The latter is especially popular in seasonal country houses.
Advantages
Perforated sheets are very easy to install. The construction of structures from this material is available even to a novice master. When transporting over medium distances, these sheets do not require special heavy equipment, since the overall dimensions and weight characteristics are quite consistent with each other. The transportation of this material is not too difficult.
PVC structures are strong and durable. The average service life of a "black cut" with a coating is more than 50 years. The steel structure is almost eternal. The strength of the material makes it absolutely safe to operate a structure made of this material even under extreme production conditions.
But the anti-slip properties of the ribbed metal surface are important not only for workshops, but also for completely civilian use in street and commercial flooring and surfaces. In addition, small holes do not become a trap for women's heels - these holes are simply smaller in diameter.
PVL decks and steps are made by welding, reinforcement and “fixing” into frames. The dimensions of the required product and the shape may vary depending on the requirements of the planned final design, but not more than the standard allows.
Types and weight of PVL
we give the typical masses of sheets from structural steel grades, while it should be borne in mind that stainless steel, due to additives, may weigh less or more depending on the steel grade:
PVL-406 - 4x1000x2100 / 3200 - 15.9 kilograms per square meter
PVL-408 - 4x1000x2100 / 3200 - 18.3 kilograms per square meter
PVL-410 4x1000x2100 / 3200 - 22.15 kilograms per square meter
PVL-506 5x1000x2100 / 3200 - 18.8 kilograms per square meter
PVL-508 5x1000x2100 / 3200 - 21.8 kilograms per square meter
PVL-510 5x1000x2100/3200 —26.1 kilograms per square meter
PVL-608 6x1000x2100 / 3200 - 25.9 kilograms per square meter
The material of the products is black or stainless steel. The “notch” made of black steel is painted or coated with any other anti-corrosion coating.
Materials used
The most common alloy from which stainless steel expanded metal is made is AISI 304, 316 and 321. The choice of a particular material depends on the operational requirements rather than on the wishes of the customer. Accordingly, the cost is formed from the price of the metals included in the alloy - the better the finished product, the higher the price of stainless steel.
The AISI 304 grade is the optimal solution for most applications. This alloy corresponds to the Russian 08X18H10, refers to low-carbon, non-magnetic steels alloyed with 18% chromium and 10% nickel. It can be exposed to moisture and a variety of chemical compounds, while it is practically not amenable to corrosion. The operating temperature ranges from -200 to +650 °C.
Areas of use
Expanded stainless steel sheets have a very wide scope of use:
For mining purposes: screening crushed rocks, making lining for workings.
For the production of steps of mid-flight and spiral staircases, as well as various floorings.
When designing light fences in need of ventilation or when organizing ventilation ducts.
For darkening balconies, windows, summer grounds and arbors.
In the construction of aviaries and cages for animals.
For reinforcing walls when laying bricks or installing underfloor heating.
In the food industry, for various kinds of screening, stainless steel expanded metal is simply irreplaceable.
PVL is made from flat metal strips made of steel. There are expanded metal sheets based on aluminum, copper, brass, but in practice they are extremely rare. For the manufacture of PVL, cold-rolled, hot-rolled and galvanized steels are used. Each of the materials has both advantages and disadvantages - consider these materials in more detail:
Hot rolled products. These objects are made from thick metal slabs, which are smelted in open-hearth furnaces. Before production, finished slabs are pickled or machined, and harmful metal scale is removed. After that, the processed slabs are rolled out with the help of presses into thin metal strips with a thickness of 2 to 50 millimeters. Hot rolled strip has many advantages - ease of production, low price, good strength. However, they also have disadvantages - an ugly appearance, susceptibility to corrosion during prolonged contact with water.
Cold rolled products. Cold-rolled products are obtained from hot-rolled blanks by additional pressing. A feature of cold-rolled technology is that the material is not subjected to heating, which complicates production, but makes the strips of better quality and strength. At the initial stage of production, mechanical or chemical etching can be performed. Cold-rolled strips have the following advantages: they look good, withstand mechanical loads well, tolerate contact with liquids and chemically active substances well. However, cold-rolled objects are much more expensive than hot-rolled ones.
galvanized products. The perforated sheet is made from galvanized sheet steel. For the manufacture of this material, cold-rolled or hot-rolled products are used, which undergo chemical or electromechanical galvanization. During galvanizing, the product is covered with a thin layer of zinc, which eventually becomes covered with a protective oxide film. Thanks to this double coating, contact of the product with the external environment is minimized, so such sheets do not rust even in case of prolonged contact with water or chemically active substances. The disadvantage of galvanized blanks for the production of PVC is a very high price, which in some cases makes their use economically impractical.
The punched sheet is made by the conveyor method, and the production algorithm looks like this:
Applying serifs. Using a knife, small diamond-shaped notches-holes are applied to the surface of the workpiece. Holes are applied in a checkerboard pattern (in the future, the material will be subjected to transverse deformation). To make the serifs of high quality, knife machines are used that allow you to create holes over the entire plane. In order to save money, cut-off metal fragments can be sent for remelting.
Workpiece stretching. After applying diamond-shaped serifs, the edge of the sheet is tucked into a device that stretches it using the transverse deformation method. During stretching, the length of the sheet increases by 30-50% depending on the type of steel and its physical properties. The resulting blanks can be used as a full-fledged expanded metal sheet, however, in practice, the blank usually goes through one more stage of processing.ki - rolling
Cold rolling. During rolling, the product is placed on a long conveyor, along the entire length of which several roller presses are installed. When PVL passes through the press, a transverse deformation of the product occurs, which leads to an increase in its length and a decrease in thickness. Cold rolling makes the sheet flatter, which has a positive effect on strength and stability. Please note that rolling is done cold without heating the workpiece, as heat treatment can damage the metal "links".
Expanded PVC sheet has the appearance of a flat surface, which has large holes-cells. This material is made of steel alloys, and the main material is hot rolled, cold rolled and chrome plated. The presence of cells can significantly reduce the weight of the material, which simplifies its use. The main areas of application of PVL are the construction of stairs, spans, platforms, the creation of fences, concrete reinforcement.
