It is sad to note, but most building materials used in suburban construction, poorly tolerate moisture and corrosion. Over time, structures made of wood, stone or metal can lose shape and attractive appearance. Steel sheet punching is not subject to negative influences. So why not start it intensively for the benefit of developers.
Expand-sheet, what is it?
product manufacturing
The use of a variety of sheet metal products for suburban construction is in demand. The demand is explained by the simplicity of installation with the use of products and the strength of the erected or prefabricated structure. Among the variety of weighty metal products, expanded expanded metal sheet is distinguished by a low weight and good frictional properties.
Expanded-exhaust sheet is manufactured in an industrial way according to TU 36.26.11-5-8 according to the technology of cutting openings on a sheet of hot-rolled steel with subsequent extraction by a certain step and rolling.
For the production of PVL use:
• galvanized steel δ from 4 to 6 mm
• cold-rolled steel. 1,5-2 mm
• hot-rolled steel δ = 4-6 mm.
The width of the obtained holes and the thickness of the sheet after drawing is regulated by the standard according to which the values of the diameter of the notch, the pitch of the cell and the thickness are indicated in the marking.
specifications
Technical characteristics of PVL are the parameters: extract, feed and cell pitch.
Great importance is attached to the width of the steel tape forming the texture of the product. Strength and specific weight of the sheet depends on the width of the tape.
The weight of the product and the maximum load per one m. are specified by the manufacturer and correspond to the tabular data.
cell configuration
The product has a specific fluted-scaly pattern with uniform application of cells of the same shape and size. The profile of the cut depends on the shape and dimensions of the cells and corresponds to the thickness of the product.
The cut-off cell consists of holes and bridges (feed), the size of a single cell corresponds to its length and width.
The configuration of the sheet cells can be:
• Round
• Square
• diamond-shaped
• Hexagonal.
Naturally, the choice of the configuration of cells and their size should be justified by the specifics of carrying out decorative and design construction works.
Helpful Tips
The configuration and size of the sheet cells allow the use of fine-mesh PVL for sifting bulk and liquid materials. Such a metal sieve facilitates and simplifies the process of preparation of working solutions and sifting of the crushed rock.
A sheet with medium-sized cells can be used to make containers and storage systems.
As a reinforcement layer when applying a layer of plaster, preference should be given to large-mesh sheets.
product nomenclature
The nomenclature of expanded metal products is represented by the following brands: PVL 406, 408, 410, 506, 508, 510, 606, 608 and 610.
Depending on the product range, the length of PVL is from 1600 to 12200 mm.
Overall dimensions of products:
Sheet width: 500; 600; 700; 800; 900; 1000 and 1250 mm;
Thickness: 0,7; 1.0; 1.5; 2.0; 3.0; 4.0; 5.0 and 6.0 mm;
Non-dimensional length within 2-3.5 m
The preferred size of the sheet for reinforcing in the repair and construction work is 500x1600 mm.
advantages of PVL
In comparison with the existing sheet metal rolling, the expanded metal sheet has the following qualities:
• easy installation of light structures using rivets, knitting wire and bolts increases the working surface or overlap
• high light transmittance and air permeability, due to different format of cells
• anti-slip properties of the product.
The above advantages of PVL have extended the scope of the product. In addition to machine building, mining and mining industry, the sheet-punching is successfully used in suburban construction.
Application of PVL in suburban construction
Repair construction work, reinforcement of the surface that produce using a sheet-punching, less time-consuming and expensive. Installation masonry woven PVL replaces the two-layer application of plaster.
In suburban construction the product is used for organizing various decking, steps of stairs and fencing the territory of a private house.
steps of stairs, staircases, bridges and decking
The bridges on the site and the external ladders from the perforation create maximum safety even in ice or snow. The steps of the flight stairs do not slip and do not freeze, simplifying the cleaning of the surface.
In comparison with corrugated and corrugated sheets, the notch is not clogged with dirt. Stair flights, which can be made by hand, is not the only option for the successful use of PVL.
manufacture of fences, fences
The superiority of the technical characteristics of the sheet-punching makes it possible to build a sectional fence, to stretch the mesh.
The sheet makes it possible to manufacture fences and fences without joints solely due to the rigidity of the expanded product, eliminating cross-pieces and reinforcing frames when mounting. Sheet punching is installed on the pillars using traditional fastening elements (bolted, stud and welded).
architectural and decorative element
We add that the cut sheet is an excellent decorative material.
The ease and delicacy of the drawing of the sheet can be used in the creation and finishing:
• ventilated facades, balcony and staircases
• external ventilation, air conditioning and lighting systems
• protective screens for windows, radiators, doors and gates
• suspended ceilings and hanging panels
• Antibuks for congresses and ramps.
anti-slip flooring
To create an anti-bug on the exit of a country house a hot rolled expanded metal sheet St0, St3, 09G2S 4-6 mm thick with a feed pitch of 6-10 mm is used. The created width of the tract of anti-slip flooring can reach 300-600 mm for heavy vehicles and 250-300 mm for passenger cars.
In addition, a sheet of punching is used to create a landscape design - topiary and green shapes.
