Marking of corrugated sheets - determination of material properties. Brands of corrugated sheets - decoding of markings and application How to find out how thick a corrugated sheet is

If you decide to make a fence from corrugated sheets around suburban area or a private home, it will be useful to familiarize yourself with tips on how and which one to choose corrugated board for a fence.

Behind Lately profiled sheet has evolved from an inconspicuous galvanized bent metal profile into an attractive material with a wide range of color shades, textures and configurations. And this is just what lies on the surface.

How to choose corrugated sheeting for a fence? Which is better or worse? What parameters of corrugated sheeting are decisive for a fence? Is it possible to use corrugated roofing sheeting on a fence? We will consider these and other questions within this article.

Corrugated sheeting for fence

1. length;
2. height;
3. frame.

These are the three pillars on which all further calculations of corrugated sheeting are based and have a direct impact on the choice.

Second, determine the duration of operation

The service life (temporary or permanent) is an important point, which, along with the fence itself, will determine the installation budget. The cost of a fence made of corrugated sheets may depend on the fencing parameters, which are difficult to change, and on the price of the corrugated sheet, which is determined by the quality of the metal profile (which in turn affects the estimated service life of the fence).

From this point of view, a corrugated sheet fence can be temporary (fencing a construction site) or permanent (a fence near a house). The longer the fence’s service life is expected, the more scrupulous you need to be in choosing it.

Which corrugated sheeting for a fence is better to choose?

To make a choice and use the right material, you need to evaluate the main parameters:

1. Corrugated sheet covering

Like any metal, corrugated sheeting, which has an iron core at its core, is subject to corrosion processes. To slow down the process of rust or prevent it, the corrugated sheet is covered with special coatings, the type and thickness of which determines the cost and service life of the corrugated sheet.

There are two types of corrugated sheets on the market, each of which has varieties:

Without decorative coating

In the first case, the steel core is coated with zinc with a density of 275 g/m2, the coating thickness must be at least 90 microns. The manufacturer provides a guarantee for such sheets for up to 5 years. In practice, it will last a little longer. Such a short service life is due to the fact that zinc belongs to the class of volatile materials and gradually erodes.

Visually, a fence made of galvanized corrugated sheets does not look very attractive and is used mainly for temporary fencing or for installation in a part of the site that is not visible.

Galvanized corrugated sheeting for fenceFence made of galvanized corrugated sheets

Corrugated aluminum-zinc sheeting is more resistant to the external environment, because... The steel core is coated with a mixture of zinc and aluminum. The warranty for this type of coverage is 10 years. Visually, the aluminum-zinc coating has a silver color with a muted shine (matte), which lasts longer than just zinc.

With decorative coating

The corrugated sheeting has additional protection in the form of a decorative finishing layer. The cost of painted corrugated sheets is higher than unpainted ones, but the requirements for zinc content are the same.

Corrugated sheeting for fences with polymer coating (polyester, pural, plastisol)

The most popular and suitable polymer coating for use in most of the Russian Federation is polyester (PE). The texture can be glossy or matte. Coating thickness 20 microns.

More expensive types of polymer coating that can withstand use in difficult conditions climatic conditions- this is pural (Pural) 50 microns, plastisol (PVC) 200 microns, polydifluorionad (PVF2).

2. Configuration of corrugated sheeting for the fence (dimensions)

This parameter is determined by the wave of the corrugated sheet and has a direct effect on the working width. Please note that the profiled sheet is installed both vertically and horizontally. The installation method does not affect its strength characteristics.

The configuration of the metal profile determines its windage. Solid corrugated sheet is subject to wind load, which can be reduced by choosing a sheet with a higher wave or arranging a powerful frame.

The “model” (size) range of corrugated fences differs in working width and wave height. Despite the fact that in the production of profiled sheets a blank of the same width of 1250 mm is used, manufacturers use different equipment, which determines the design of corrugated metal profiles.

Note. In practice, this leads to the fact that each manufacturer has its own profiled sheet, and it will not be possible to join two sheets from different manufacturers correctly.

What kind of corrugated sheeting is needed for the fence?

For the fence, corrugated wall sheeting with a wave height of 8, 10, 15, 17, 18, 20, 21 mm is used. The most popular are 8, 10, 21.

The characteristics of corrugated sheets are given in the tables

C8 corrugated sheet for fenceC10 corrugated sheet for fence
C21 corrugated sheet for fence

An important pattern that needs to be taken into account when choosing: the higher the wave height, the smaller the working width, but the greater the rigidity of the fence. Masters advise having too much strength rather than too little.

3. Thickness of corrugated board for the fence

The most controversial of the parameters. The fact is that the thickness of the corrugated sheet directly affects the strength of the fence.

What thickness of corrugated board should I choose for the fence?

Sellers advise purchasing thicker metal - 0.5-1 mm. However, craftsmen and many users agree that a reliable frame can compensate for the small thickness of the corrugated sheet. From the point of view of cost and labor intensity of work, this is a controversial issue, but the fact that a durable frame is able to level out the windage of a sheet and gives it rigidity is unambiguous.

Therefore, the most optimal thickness for users is 0.45. Taking into account the permissible deviations in GOST 24045-2010 and EN 10143 of +/- 6 mm. in fact it is 0.39 mm. However, professional installers provide a guarantee for a fence with such corrugated sheeting.

How to check the thickness of corrugated sheets?

The seller is obliged to provide all sheets for thickness measurement. As for the thickness of the zinc coating, there are three options - either take the seller’s word for it, or demand documents for the metal coil from which the corrugated sheet is rolled. Again, you need to remember that the documents can be for one bay, and the rental is made from another. The third option is to send the sample to a laboratory for analysis. But installing a fence made of corrugated sheets with your own hands is not such a large project as to waste resources on analysis.

4. Color of corrugated fence

Color does not affect the strength characteristics of the fence, but it determines the visual appeal and affects the price of corrugated sheeting.

All manufacturers (except Ruukki (Finland), which use the RR color layout) use the standard Ral table for color designation. Thanks to this, corrugated sheets from different manufacturers are maintained in the same color scheme.

What color to choose for corrugated fence?

The question is rhetorical, but according to statistics, among the favorites are 8017 (brown), 3005 (rotten cherry), 6005 (green), 6002 (light green).

Today, a popular solution is to use corrugated sheeting coated with printech with patterns like wood, brick, stone, etc. Printech imitation corrugated sheeting looks very advantageous in the finished product. And the decor, in the form of columns, posts or forged parts, only gives the fence solidity and prestige.

Note. It is important to know that any coating is exposed to ultraviolet radiation, i.e., it fades. But, high-quality coating burns out evenly. In terms of speed, this process can be compared to the fading of paint on a car. However, if the sheet is replaced, the difference in shades may be noticeable. Even purchasing a sheet “just in case” will not save the situation.

Glossy or matte corrugated sheeting is another point that determines the appearance of the fence. The matte surface looks more noble, but it loses its attractiveness after rain, because... dirt from the soil settles on the surface of the fence. It is advisable to place such sheets on a foundation or constantly clean them. The point is not the attractiveness of the fence, but the fact that small particles of dirt increase the rate of destruction of the sheet coating.

To choose the right profiled sheet for a fence, you need to pay attention to a few more nuances:

• leaf appearance. Large deviations in width and length (above the permissible GOST 19904-90) should alert you when purchasing (substandard);

• front surface quality. Peeling of paint, blistering, stretching, scratches - all this will lead to destruction of the surface and inevitable corrosion. Dents do not cause much harm to the corrugated sheet, but they also do not decorate the appearance of the fence;

• cut quality. Typically, the length of the sheet is set at the profiling stage. Guillotine cuts off a metal sheet smooth, without nicks. Using a grinder or other cutting tools results in an uneven cut - this is a direct path to the appearance of rust at the cutting site;

• overlapping wave geometry. It should fit perfectly onto the wave of the previous sheet. There is no need to believe the seller’s statements that the sheet will be pressed with an additional screw. A sheet screwed to the sheet, and not to the frame, will not hold the self-tapping screw, and installing additional support or joists is costly;

• presence of film. It is not a mandatory attribute, but will protect the sheet from damage during transportation;

Advice. After installation of the corrugated sheeting is completed, the film must be removed. Once it dries to the surface, the film is practically impossible to remove.

• availability of guarantee and other accompanying documents.

Note. If the calculation of the amount of corrugated sheeting is carried out by the seller, he must provide a layout diagram of the sheets. This is especially important during roofing work, as well as during the construction of a fence of complex configuration.

Peeling coating on a corrugated fence Taking these factors into account will help make right choice fence corrugated sheeting and avoid the situation shown in the photo.

Agree, this is a convincing example of why you shouldn’t save money on purchasing profiled flooring.

Price of corrugated sheeting for a fence

Based on the foregoing, we can conclude that the price of corrugated sheeting is an objective value that is determined by the thickness, type of coating and quality of the finishing layer of the sheet. Corrugated sheeting, the cost of which is lower than the market price, by definition cannot be of high quality.

Advantages of a fence made of corrugated sheets

• strength;
• maintainability;
• almost any shape;
• relatively low cost;
• resistance to bad weather and mechanical damage;
• beautiful appearance and the ability to combine with other materials (goes well with stone).

In addition, you can make a fence from corrugated sheets with your own hands, since it is not demanding in installation and maintenance.

What characteristics of corrugated sheets can be checked at home?

In pursuit of low prices, Chinese manufacturers of galvanized painted metal violate all conceivable and inconceivable parameters. Corrugated sheets made from it have much lower service life and consumer properties.

What characteristics of corrugated sheeting are most important during operation?

• The thickness of the galvanized steel base.
• The thickness of the zinc layer, which prolongs the service life.
• Characteristics of the polymer coating. Based on these characteristics, one can judge the service life of corrugated sheets.

So on all types of corrugated sheets upper layer This polymer coating. You can simply check it by using a large coin and scraping off the paint. If it comes off in several layers, then you can roughly judge the quality of the polymer coating.

The next parameter is steel thickness. If the thickness is less than 0.45 mm, you cannot walk on such a roof; there is a risk of sagging and, as a result, falling. Unfortunately, it is impossible to measure the thickness in the field; it is checked in laboratory conditions. However, some advanced roofers use particularly precise micrometers, which allow them to accurately reject corrugated sheets with low thicknesses of 0.375 and 0.4, as well as 0.42 mm.

Also, using particularly precise micrometers, it is measured zinc layer on corrugated sheet.The weight of zinc is directly proportional to the thickness. So, if there are 275 grams, the zinc coating layer is 0.02 mm. As a result of these studies, you can verify that the purchased corrugated sheet has the necessary characteristics.

Remember that the presence of a certificate, as many sites offer, does not at all guarantee their compliance in a particular bay of metal. And during a crisis, many simply abuse this. If it is not possible buy corrugated sheets from trusted suppliers, then just try using a coin, as we described above.

Corrugated roofing sheeting is made using bending equipment using the cold rolling method. It’s not entirely clear what we’re talking about? Are you buying building materials for the first time? Then it is important to know some of the nuances of choice and be able to check the quality of the product, despite the excellent indicators in the documents. Sometimes this is not true at all. To avoid buying a fake or defective product, follow our simple tips.

All senses help us

At the moment, in almost every region of our country there are many companies producing corrugated sheets. The first thing you need to ask the consultant about is the raw materials used for the building materials and the country producing them. The high quality of steel produced by Russian metallurgists has already been recognized abroad. Therefore, it’s time to stop scolding your manufacturers and overpaying for imported analogues of the same quality. And you should be wary of raw steel of Chinese origin. They are lower in production level, so purchasing such a profiled sheet is at your discretion.

Strength test

Press down on the sheet with your hand or bend it slightly. The corrugated wave on the surface should return to its position. If this happens slowly, it means that the roof may become deformed during operation.

Quality is determined by ear

By knocking on the profiled sheet, you will hear a certain sound. What should it be like? Sound and clean! Any rattling indicates poor quality of the steel used.

We take a closer look

Corrugated sheeting with a polymer coating is much more durable than its galvanized counterpart. But if it is applied according to all the rules and there are no defects on the surface. It is impossible to hide them - these are abrasions or uneven painting. In this state of affairs, it is worth buying a profiled sheet elsewhere. Run your hand over the material, absolutely smoothly, do your hands feel any roughness? Then everything is fine. Polymer paint good quality creates an even layer and is resistant to bad weather during operation.

The manufacturing method makes itself felt

If you see water stains on the surface of a profiled sheet, then consultants sometimes pass them off as a unique design. This actually means that an emulsion was used in production. Such sheets are more often susceptible to corrosion; rust begins to appear on them very early.

Buy high-quality building materials, build your houses, live long and happily!

Corrugated sheeting is a popular roofing material, which is a galvanized and corrugated steel sheet, on top of which a special polymer coating is applied.

Depending on the size, weight and manufacturer, the types of coating and other parameters that ultimately determine the choice of corrugated sheeting may vary.

Considering the wide variety of products on the market, buyers are wondering: what kind of corrugated sheeting is needed for roofing? Is it suitable for? What sizes and markings are there in principle? We will answer questions and provide the reader with information that will be of practical use to him.

Markings and types of corrugated sheets

Finding out the main characteristics of this building material is quite simple. It is necessary to consider the inscriptions that are on each sheet - they are the same for all manufacturers and are standardized under the domestic GOST 24045-94.

According to this GOST, it is customary to distinguish the following types of corrugated sheets:

Important: despite different types markings, it is allowed to use profiled sheets for purposes other than their intended purpose.

For example, profiled sheets “C” can also be used in roofing work, but in this case it is necessary to make the roof with a large slope, and it must be very dense, if not continuous. The same applies to roofing sheets - they can be used to install fences, but additional cross beams must be installed.

To avoid such technological complications in the construction process, it is recommended to use sheets only for their intended purpose.

Scope of application of corrugated sheets

Often various brands corrugated sheets have similar characteristics, which is why you have to choose the material solely based on cost and appearance sheets.

We reviewed the most popular brands of corrugated sheets and compiled a corresponding table so that the reader could navigate the functional purpose of each brand:

Scope of application of corrugated sheets with characteristics

Based on the scope of application, it is necessary to determine the specific parameters of the profiled sheets.

So, based on the parameters, you can use corrugated sheeting to build a gate. Made and beautifully designed, it will fit perfectly into the surrounding landscape.

After the gate is installed, you need to make a lock. A lock for a gate made of corrugated sheets can be very diverse. All possible locks for the gate are listed. The choice will be up to you.

Sheet dimensions

Dimensions are necessary to determine the required amount of material for carrying out installation work. In addition, it is necessary to know the weight of the profiled sheets - this way the maximum load is calculated and the type of lathing that should be used to install the corrugated sheets is determined.

Length and width of profiled sheets

Let's consider standard sizes corrugated sheets of the most common types:

To determine the length of the profiled sheet, you need to look at the last numbers in the marking on the product. The length of one sheet can be either 2.5 meters or 11 meters or more.

Sheet thickness and wave height

The height of the wave directly depends on the type of profiled sheet. Thus, load-bearing and roofing sheets can have a large corrugation, the height of which is in the range of 35-44 mm. Wall sheets used for finishing can have a width of 13 mm. Accordingly, the wave height of each subsequent type will be 3-3.5 mm higher.

Sheet thickness:

• Sheets marked “H” have a thickness of 0.55 to 0.9 mm. Accordingly, the weight of one square meter sheet can vary between 7.4-11.1 kg
• Sheets marked “NS” have a thickness of 0.55-0.8 mm. Weight - from 6.3 to 9.4 kg
• Sheets marked “C” are the lightest and thinnest - thickness is in the range of 0.55-0.7 mm, and weight is from 5.4 to 7.4 kg

Dimensions various types corrugated sheets

Conclusion

After all the given parameters, the reader will be able to determine which material will be optimally suited for certain types of installation work. It is necessary to take into account that all the given types and sizes were compiled in accordance with the current GOST. When purchasing foreign profiled sheets that do not have GOST certification, deviations from the above characteristics are possible.

Today, for various construction work(including for roofing) a wide variety of grades of corrugated sheeting are used. And there is nothing surprising in this, because the low cost of this material and ease of installation make it extremely popular in the construction market.

But the variety of all kinds of brands also has another side - sometimes it is quite difficult to figure out which brand will be suitable for solving the required construction task.

Let's look at how the markings applied by the manufacturer to the profile sheet can be deciphered and for what purposes the most common brands are intended.

Marking of corrugated sheets - explanation using an example

When choosing corrugated sheeting, the markings indicated on its sheets become a real storehouse of valuable and useful information. Only for an uninitiated person these symbols - numbers and letters - will not carry any meaning or value.

Every person who decides to work with corrugated sheets needs to at least generally learn the principles by which this building material is labeled.

It is best to explain the marking of corrugated sheets using an example. For example, on a profiled sheet there is applied the following text:

Brand: S21-0.45-750-11000

• The first letter (C) means:

Wall corrugated sheeting, which is intended for cladding walls, erecting fencing, and so on. Also, C21 corrugated sheeting is used for roofing work and is used as a basis for a soft and independent roof.

Despite the fairly low waves, the profiled sheet still has a high mechanical stability and this is facilitated by their symmetry and frequency. And it is the rigidity of the profile that is sufficient good reason, why this brand of corrugated sheet is widespread.

Thanks to the extreme waveforms, an excellent level of joining is ensured and this is certainly obvious advantage corrugated sheet C21. The Finnish RAN-20SR is used as a European analogue of the C21.

Brand: Profiled sheet C44.

C44 is considered a standard metal profile for roofing structures and its shelves do not have additional stiffening ribs. The covering width of C44 is equal to one meter and this contributes to the fairly wide use of this profiled sheet for the purpose of wall cladding and the construction of roofing structures. The minimum thickness for this profiled flooring is 0.5 millimeters.

Brand: Profiled sheeting N57 – 750

This profile brand is considered one of the most common in construction due to its optimal combination of available characteristics:

• total coverage width
• bearing capacity indicator
• price indicator

Due to the inclusion of this corrugated sheet in the standard GOST 24045-94 a common part calculations should be performed depending on this brand of corrugated sheet. In addition, today it is difficult to produce profiles of this brand due to the lack of blanks of the required width, which are made from high-quality rolled steel.

This metallic profile It is made from special rolled steel with a width of 1250 mm, as well as a rolling grade of 220 and more. Often it can be used as an alternative to P57-750 corrugated sheeting.

This profile is intended for work related to roofing, but can be used to create all kinds of enclosing elements, as well as for elements of various permanent formwork.

The maximum pitch of the lathing used for this corrugated sheeting is three meters. It is classified as universal building materials. It can be used for fencing and wall cladding, and also as a roofing material.

The mechanical properties of corrugated sheeting can be ensured using rigid ribs rolled using flange technology and by using it as a base steel sheet galvanized type with a thickness of 0.8 millimeters.

Thanks to a large number stiffening ribs per unit of total area, it is possible to use the NS-35 grade as a coating on the sparsely used sheathing with a one and a half meter pitch.

Double-sided polymer painting is used only for the NS 35 brand with a thickness of 0.5 millimeters.

This grade can be made of steel sheet with a width of 1.4 meters with rigid ribs with a depth of seven millimeters. NS44 corrugated sheeting can be considered universal and suitable for wall and roofing systems.

Due to the high strength of this profile, it is possible to install it on the sheathing with a spacing of up to two and a half meters.

This brand of corrugated sheet is traditionally used as an independent roofing material and as a basis for soft roofing material. In addition, this profile sheet can be used as permanent formwork.

Corrugated sheeting is stamped from roll-type steel fox with a width of 1250 millimeters. This type of corrugated sheet may differ high performance versatility and excellent mechanical performance, a wonderful level of accessibility.

Brand: .

Similar to the previous grade of corrugated sheeting, grade H75 can be positioned as a profile for roofing work. It can be used for the purpose of arranging various metal roofs, as well as permanent formwork. It can also be used as a base for membrane-type roofs.

The main material in the production of this corrugated sheet is rolled steel of the highest quality.

This brand is considered one of the most popular brands that are used in many fields modern construction. Therefore, it is not surprising that in terms of production volumes and current sales volumes, this brand is the undisputed leader.

It goes without saying that this is far from full list grades of corrugated sheets. Moreover, from time to time new types begin to appear on the construction market.

By the way, you can watch a video on how to cut corrugated sheets:

First of all, markings can help you understand the characteristics of profiled sheets. It is necessary to use only the type of profile suitable for the type of construction that you are carrying out. However, careful thought and analysis will help you make the right choice.
