What is professional flooring and how to choose it?

Professional flooring – reliable and universal material, which is popular with developers. It is suitable for roofing, lining of walls, installation of partitions and fences – you only need to choose a suitable type of steel sheet according to the existing task.

What is it and the better slate?

Material is a metal sheet with a corrugated surface. He has pronounced ribs that pass along the entire length. This allows the proflket to withstand elevated loads. Steel sheets differ in the form of the profile and the material of the coating, which affects the characteristics and determines the scope of application.

Often there is a confusion between the two names – professional flooring and professional. In the global sense, this is the same sheet material with a profile obtained by cold rolled products. However, often under the word “professional flooring”, it is a roofing coating, and the product “Proflist” is used for products that will go to the construction of partitions, fences, wall cladding. It can be concluded that the differences are in the characteristics.

As a rule, the following indicators are taken into account.

  • Rigidity. For the roof, you need more durable sheets that can withstand a serious load – the impact of wind, the weight of snow in winter. Taking into account this, the profile height must be at least 35 mm.
  • Soundproofing. Material with a tighter profile eliminates loud noise with strong rains.
  • Features processing. Professional flooring due to higher strength is worse than bending, so the fence is easier to make from the professionalist. He can give any shape without applying special efforts.

In any case, the material can be referred to in different ways, so it’s better to look at the marking – there is all the necessary information that will help find suitable products.

Professional flooring gained mass popularity relatively recently. Previously, slate used as roofing everywhere, but it’s not worth returning to it.

There are several reasons why you should choose a professional flooring if you are planning the roof repair.

  • Ease. Slate has a weight of about 9 kg per m2. Steel sheet – an average of 4-5 kg, depending on the type of profile. Obviously, with a light material, installation work will be faster, it is also easier to transport it.
  • Strength. Although slate is good with the horizontal load, it can split during bending or impact. Also from uneven styling, the material will go cracks and can break down if it is used during the cleaning of the chimney or at any other work that you need to perform on the roof. Professor calmly withstands human weight and resistant to impact.
  • Aesthetics. Standard gray slate looks small, and color does not differ in the brightness of paints and a variety of options. When buying a professional flooring, you can choose anyone from the RAL palette, and some brands offer branded shades. In addition, the coating can be glossy or matte, it does not fade in the sun.
  • Features of operation. Slather absorbs moisture, which leads to the appearance of moss and gradual destruction of the material. In addition, dust will be at richly on the porous surface, so you have to constantly clean the roof so that it looks neat. With a professional flooring there are no such problems, and it is easy to care for it – you can water the hose water to wash off the dirt.
  • Foreign safety. Although slate is not lit, in the fire he begins to “shoot”, creating sparks, which can lead to the emergence of new foci of fire or cause injuries to people. Professional flooring does not support combustion.

At the price of both materials are quite accessible, although the cost of metal sheets can vary, depending on the characteristics. Nevertheless, the operational qualities of the professional flooring speak for themselves. From this material will be a durable and beautiful roof.

How to make professional settles?

Material production is almost fully automated – it allows you to get sheets in large quantities and makes them available to buyers. For the manufacture of the professional sheet uses a cold rolled method. Profiling is performed by one of two ways.

  • With simultaneous rolling of all corrugations. Such equipment requires less area and allows you to optimize production processes.
  • With consistent rolling. This method minimizes the likelihood of marriage on metal products.

After rolling, the final stage of processing. The metal is trimmed with hydraulic scissors in accordance with the specified parameters, then the product enters the receiving device where its characteristics are automatically evaluated. Proflists make stainless or conventional steel – in this case, the surface is covered with zinc layer to avoid the appearance of rust. Lighter products are usually aluminum – this material is used to facilitate the weight of the structure.

For production, guest regulations are used, which dictate the allowable product parameters. They may differ, depending on the initial composition of steel. There are also separate standards for protective coating.

Properties and characteristics

Operational qualities directly depend on the type of profile, therefore it makes sense to consider the features of the most common species to select an option for a specific task.


Such sheets have a wavy surface and not too high strength. More often they are used to install barriers, cladding, but sometimes they can be used and as roofing, if the roof has a big angle of inclination, and snow will not accumulate there. Possess the following characteristics:

  • Thickness – from 0.5 to 0.7 mm;
  • Length – up to 12 meters;
  • Profile height – 8 mm.


Sheets with a trapezoidal form profile. Protected by polymer coating that does not allow corrosion. Suitable for the roof with a shave step of no more than 80 cm, for cladding walls of garages and other structures, to arrange a fence in the territory. Product Parameters:

  • thickness – 0.4-0.8 mm;
  • Length – up to 12 meters;
  • Profile height – 21 mm.


Durable products have a ribbed surface and protective polymer coating. Well suited for laying on the roof in the shave step up to 1.5 meters. The flooring is sealed and reliable. You can also use sheets as partitions and sandwich panels. Properties of the professional sheet of this category:

  • thickness – from 0.5 to 0.9 mm;
  • Length can reach 12 meters;
  • Profile height – 35 mm with a step of a trapezium in 200 mm.


The profile for such sheets has the outlines of the trapezoid. Feature – the presence of gutters. This allows you to use a thicker layer of insulating material when installing, which increases the reliability of the structure. Sheets are used in roofing, for laying a non-removable formwork, installation of shield barriers. Product Features:

  • thickness – 0.6-0.9 mm;
  • Length – up to 14 meters;
  • Profile height – 57 mm.


Professional flooring this category is of high strength. This contributes to the presence of additional rigidity. These sheets have more than others, can reach up to 15.3 kg per m2. Products are used for installation of structures subject to significant load. Parameters of sheets:

  • thickness – from 0.8 to 1 mm;
  • Length – up to 13 meters;
  • Profile height – 114 mm.

Description of species

Manufacturers produce a lot of varieties of the professional leaving of practical or decorative designs. You can find options with different types of profiles – curly, arched, sea wave, trapezium. Smooth and flat metal shutdown without corrugation to the proflist no longer belongs. You can find perforated products – the presence of holes facilitates installation. By type coverage, the professional sheet is painted or galvanized. The most common classification of the professionalist – on the scope of application. Three types of products are distinguished.


Such sheets are used for installation of structures subject to serious loads. It may be a roof, which accumulates a lot of snow, carrying walls or partitions, overlap. Products are distinguished by a long service life – from 40 to 60 years. Sheets can be found in high profile and additional furrows necessary to give strength. This category includes brands: H57, H114.

Usually possess a rectangular or trapezoid profile. Applied not only for cladding walls, but also for the construction of fences, including decorative. Sheets of this type are thinner, so they are easy to handle – cut, bend, drill holes. S8 and C21 brands are used in demand.


These products have sufficient rigidity and strength to withstand loads, but at the same time they have a small weight, allowing not to lose the roof. Sheets are characterized by an attractive design and a variety of colors. They are also used to install fences. Examples of brands: NS44, NS35.

Geometric data and volume

The length of the sheets can reach up to 14 meters in some varieties, but is more often limited to 12 meters. If necessary, the product can be cut, because such large copies are needed everywhere. For example, for the installation of fences, it is often ordered by 2 meters sheets, for the walls of the walls – 3 meters, the length of 6 meters is also in demand. When buying it is worth paying attention to the width. It is indicated in two dimensions – general and working. The first is the initial width of the sheet, the second one, which turned out after the formation of corrugations. Calculations for construction take into account the last.

Product thickness can reach from 0.4 mm to 1.2 mm. This is quite enough to create a durable coating, because the ribs of stiffness increases the material, allowing it to withstand significant loads. The weight of the sheet depends on its dimensions and thickness. It also affects the distance between corrugations and the structure of the coating.

Usually indicate the weight per square meter, but knowing the product parameters, it is easy to calculate the area and understand how much the sheet weighs the entire.

Color gamma and design

Ral and RR palettes are used for metal rolls. They contain a large number of shades, for example: red, yellow, pink, green, blue, purple and others. You can also order original staining under the bar or other texture. Even after a long time, the coating does not fade under the influence of sunlight and remains the same bright.

Marking sheets

Products have a diguristic code that contains the main characteristics. Disassemble the notes. The first is the letter, and here are three options:

  • C – wall sheet;
  • N – carrier;
  • Ns – universal products that can be used for facing and roofing.

Next follows a digit pointing to the height of the profile. It can be written through a hyphen or immediately, for example: NS-44, NS-21, SS10, C8, H57.

After that, you can see another three numbers:

  • sheet thickness;
  • total product width;
  • length.

Full marking usually looks like this: C18-0.7-750-6000. It can be understood that this is a wall sheet with a profile of 18 mm, its thickness is 0.7 mm, and the total width is 0.75 meters. Length of this product – 6 meters.

When buying it is better to choose products of proven companies that have won a good reputation in the market. As a rule, large plants use modern equipment that minimizes the probability of marriage and allows you to produce products with various parameters. There are many manufacturers who can offer high-quality professional flooring.

  • “Neva Steel”. Located in St. Petersburg, there are more than 15 years. Releases finishing and roofing materials, as well as insulation, drainage systems, window structures and other goods for construction and repair.
  • “Sevzapcomite”. Located in Nikolsky. Specializes in fiberglass and composite products, including supplies a professional sheet for roofing and walls.
  • Far Eastern factory professional flooring. Located in Vladivostok, produces various types of metal.
  • Profometal. Manufacturer from Stupino, offers everything necessary for the arrangement of the facade and roof.
  • Ural roofing plant. One of the oldest companies has been working for more than 25 years, located in Yekaterinburg. Delivers roofing materials wholesale.

Child Nuances

It is important to choose a material that matches the tasks. Then the coating will not deliver problems and will last long. In addition, there are other points that should be taken into account.

  • Better to buy goods from one supplier. It would be more profitable to immediately calculate the required amount of material and order a batch. It eliminates long searches like a sheet of sheet if the products suddenly end.
  • Fasteners and challenges should be ordered with coated. So you will be sure that the details and sheets have the same shade.
  • Carefully examine the packaging. It must be a whole, without damage. Also, the products themselves should not have defects – scratches, dents and other traces.

If you are planning roofing, it is better to order long sheets. With short consumption of the material will increase due to the laying of the mustache, in addition, a large number of joints looks nonethetically.

Scope of application

Professional property is used in industrial and private construction. Thin thin sheets go to the inner decoration of the walls or the ceiling in the work space. They make partitions in large shopping pavilions and hangars, apply for installation of kiosks. The sheet material is medium thickness used to cover the facade of the house or bath. Also from it you can make a visor over a gate or canopy over the porch, put on the roof of the arbor. The most durable sheets with a large profile height are used when mounting the carrying floors, roofs with a wide step of the crate, of which formwork when filling the foundation.

Professional property is often used to install fences. From it you can collect a fence of any height, mount a large gate for the entry of transport or make a decorative design for a palicator. It is not recommended to apply a professional flooring where the constant impact of the aggressive environment is possible. This can lead to corrosion. Also, the material is not suitable for roofing without a crate – condensate will accumulate under the sheets under the sheets.

Operation and care

Although it’s not too difficult to work with a straightener, there are certain nuances that you should know not to spoil the material. Often there is a need to cut the product, but not all tools are suitable for this. Can be used:

  • electric saw with a special disk for a professional sheet;
  • manual hacksaw for metal – if the amount of work is small;
  • Scissors for professional flooring – there are electrical and mechanical, suitable for thin sheets.

Gas layering devices are not recommended – the metal is spoiled from heating. Also do not use the grinder, since the disk with an abrasive coating creates damage to the edge, which can subsequently lead to the appearance of corrosion.

No less important point – drilling holes. Usually they are required to install fasteners. It is better to use special tools for this purpose – hole punch or piercing holes. If you need to put the screws, then the drill is suitable, but it is important to monitor the speed of revolutions and not forget to remove the chips.

It happens that you need to bend a sheet on the corner, make a P-shaped bar or arch. This can be done with a special bending machine – there are not only industrial, but also manual models that are suitable for private use. Some craftsmen can bend a sheet across at home with a hammer, but with such a highly likely to get an uneven line.

Steering profile should be determined in a certain way that the coating is reliable:

  • Stying begins from the lower angle of one of the roof ends;
  • Windbar must be installed after fastening the end series;
  • If the sheets lie vertically, the overlap must be at least 20 cm.

Correctly put the professional flooring and do it yourself, if you follow a phased plan of work and comply with safety. As for the care, then it usually does not arise difficulties. The roof is washed with rain, and snow without problems comes off from it in the spring. Walls covered with sheet, you can wash out of the hose or use soap solution. When the scratches appear, it is recommended to get the paint of suitable color to eliminate defects.

Professional flooring unpretentious, coverage from this material can serve a lot of time subject to compliance with the technology of installation and processing.
