Characteristics and scope of application of load-bearing corrugated sheets. Bearing capacity of corrugated sheets

Home improvement begins with the right materials. Great solution there will be corrugated board. This material has such qualities as durability, reliability, strength and has an attractive price. Also not the least factor is the fairly light weight of the corrugated sheet. This article will describe in more detail the weight of 1 m2 of corrugated sheet.

Features of the profiled sheet

Profiled sheet is made of galvanized steel. Using a special press, profiles of a trapezoid, wave or ridge are extruded onto it. To improve its anti-corrosion qualities, it is treated with a layer of polymer or paint coating.

Basically, corrugated sheeting is intended for But I also found corrugated sheet wide application for installation of fences, canopies and other premises. It is also used as a material for covering walls.

Advantages of a professional sheet

Corrugated sheeting has a wide range of advantages. The main advantages of corrugated sheets:

• Light weight. On average, the weight of 1 m2 of corrugated sheet varies between 7-9 kg. This greatly facilitates both transportation and construction work.
• Durability of the profiled sheet. The material tolerates temperature fluctuations well, is resistant to rotting and fungus, and is resistant to corrosion.
• Strength of the material. Can withstand heavy loads due to its high load-bearing properties.
• Ease of use. Installation can be performed without specialized equipment, and standard size sheet allows you to economically cover a roof of any area.
• Variety of colors. Has a lot color solutions, which allows you to choose a color to suit every taste.

Types of corrugated sheets and their weight

Profiled sheet is used for various types construction. Therefore, each of them has a number of characteristics, thanks to which you can easily select the necessary corrugated sheet for any area of ​​use.

There are load-bearing, wall and universal profiled sheets. They differ in both their dimensions and weight. Data on the dimensions of corrugated sheets can be found from its markings:

• The first letter indicates the area of ​​application. The letter “N” means load-bearing, the letter “C” means wall, and the letter combination “NS” means universal.
• The first number is the height of the corrugation in mm.
• The second number is the width of the profiled sheet in mm.
• The third number is the thickness of the corrugated sheet in mm.

Depending on the brand, the steel profiled sheet has a different weight 1 square meter. Least weight One m2 of corrugated sheet starts from 4 kg. Universal profiled sheet usually has the highest weight - up to 21 kg per 1 m2.

Wall corrugated sheeting: description of popular brands

Profiled sheets marked “C” are used mainly for wall cladding, but are also used for the construction of fences, partitions, fencing and other similar objects. A profiled sheet is made from a steel layer of metal with a thickness of 0.50-0.70 mm, and has a profile height in the range of 8.0-44.0 mm. The weight of 1 m2 of corrugated sheets ranges from 3.87-8.40 kg.

Profiled sheet marked C8 it is applied for decorative cladding walls, as well as for the construction of light structures, partitions and other fragile objects. It has a profile “wave” height of 8 mm. To produce C8 corrugated sheets, I use profiled galvanized steel corrugation, which is covered polymer materials. The weight of 1 m2 of C8 corrugated sheet is in the range of 3.86-7.3 kg.

Profiled sheet marked C21 used for wall cladding, also for fence construction and roofing works. It is made from corrugated sheets and has increased rigidity due to profile stamping. The “wave” of the profile is made in the shape of a trapezoid and has a height of 21 mm. The weight of 1 m2 of profiled sheet C 21 is from 4.44 to 8.45 kg.

Load-bearing corrugated sheet

A profiled sheet marked “H” is called load-bearing or roofing. It is used, respectively, for roofing work, as well as for the construction of hangars, fences, trading platforms and other structures with for a long time services. This profiled sheet has increased load-bearing qualities. For its production, steel corrugated sheets with a thickness of 0.70-1.0 mm are used, and the profile height ranges from 57-114 mm. The weight of 1 meter of square corrugated sheet will be from 8 to 17 kg, depending on its thickness.

Profiled sheet brand H60 Most often used for roofing work. But it is also used for installing permanent formwork and some other construction projects. The weight of 1 m2 of H60 corrugated sheet varies between 8.17-11.1 kg, depending on its thickness.

Profiled sheet of the H75 brand has gained the greatest popularity among other brands due to its higher mechanical characteristics. Sheets with this marking can withstand heavy loads, both vertical position, and in horizontal. Most often, such profiled sheets are used for: Corrugated sheets are made from zinc-coated steel, with a thickness of 0.66 to 0.90 mm and a weight of 1 square meter within the range of 9.2-12.5 kg.

Universal corrugated sheeting: description of popular brands

The universal profiled sheet is marked "NS" and has average technical characteristics. Thanks to this, corrugated sheeting can be used for any type of work, but most often it is used for roofing. Corrugated sheets are produced with a thickness of 0.56-0.81 mm and a corrugation height that can be no more than 44 mm, and the weight ranges from 6.30 to 9.40 kg.

Profiled sheeting brand NS35 used for covering roofs with a slight slope, constructing fencing, fences, and various prefabricated objects. It is made of sheet material coated with zinc or galvanized material with a polymer layer. The trapezoidal profile gives increased strength. The profiled sheet has a thickness from 0.40 mm to 0.80 mm. The weight of 1 m2 of corrugated sheet also depends on the thickness and ranges from 4.46-8.41 kg.

H44 is used for the construction of various and also for roofing works. Because of his high profile(44 mm) has increased rigidity. The thickness of the profiled sheet is 0.7 mm and 0.8 mm. Accordingly, the mass of 1 m2 will be 8.30 kg and 9.40 kg.

Weight table for different grades of corrugated sheets

Most often, different manufacturers have the same brand with the same characteristics. This is due to the fact that they are manufactured in accordance with GOST 24045-94. The table below shows the brands of corrugated sheets and their sizes.

Permissible deviations for the following parameters:

• length - 10 mm
• corrugation height - 1.5 mm
• profile width - 0.8 mm
• weight - 20-100 grams.

The most reliable sheet is considered to be the one with a mass of 1 m 2 and mass linear meter practically coincide.

In general, when choosing a profiled sheet, you need to know not only its parameters, but also its weight. Thus, a difference of 1 mm in sheet thickness can equal a difference in weight of over 15 kg. For example, the weight of 1 m2 of corrugated sheet is 0.7can be from 6.5 kg to 9.8 kg.

To create a reliable and durable roof structure, load-bearing corrugated flooring is used, which has a number of features and advantages. This material is presented in several brands, differing technical properties and characteristics, design and strength level, rigidity. The necessary parameters and properties of the load-bearing corrugated sheet are determined depending on the operating conditions of the structure, the expected load on the roof, and others important factors. In any case, it is mandatory to accurately calculate all parameters and take into account the characteristics of the material.

Corrugated sheets in tables and figures

Features of load-bearing corrugated sheets

Metal profiled sheets are very diverse. This material is in demand in the construction of a wide variety of structures and objects. A special type of corrugated sheet is load-bearing corrugated sheeting, characterized by a high level of rigidity and strength. The material is suitable for creating roofing, ceilings and other important elements building. The characteristics of the load-bearing sheet ensure the safety and reliability of the home.

Types of corrugated sheets have such a parameter as load-bearing capacity. This indicator is important because it determines the reliability of the sheet. Hardware have enough simple technology manufacturing, which allows you to obtain a material with a good degree of rigidity. For this purpose, roll steel sheets are processed on profile bending machines and therefore the elements acquire stiffeners. These structural parts may have different heights comb, shape and characteristics.

The self-weight of the load-bearing corrugated sheets combines well with a high level of rigidity and reliability. Such qualities ensure the use of elements for the following purposes:

• Roof covering device various types and with a large lathing pitch of three or more meters;
• Reliable permanent formwork for monolithic floors, roof structures of buildings;
• Interfloor ceilings made of composite materials, rigidity diaphragms for structures with a supporting metal frame;
• External wall fencing of various types of design.

High degree of reliability and optimal characteristics, which has a load-bearing corrugated sheet, allow the use of metal sheets for the construction of structures subject to intense and significant loads. In harsh climatic conditions This material is also practical, but it is important to follow the installation technology. In any case, load-bearing corrugated roofing is a material that is reliable, durable and safe.

Metal elements are in demand in construction. The characteristics and design features of the sheets make it possible to reduce the production time of structures, as well as construction costs. For example, the grade of load-bearing corrugated sheet H75 has a number of features that allow installation with a large lathing pitch or a distance between purlins of 5 or 7 meters. IN in this case the costs of creating a base for corrugated sheets are reduced, but it is ensured high level reliability of the roof, which can withstand significant loads.

The choice of the optimal brand for creating a roof deck or floors depends on the required level of characteristics. It is important to take into account the following properties and parameters of the material:

• Sheet dimensions, as well as useful width, which is calculated taking into account the overlap;
• Thickness metal sheet- can be in the range from 0.6 to 1.5 mm, but this parameter determines the strength of the coating;
• The type of coating, for example, galvanized material is characterized by low resistance to moisture and chemical influences, and elements with a polymer layer have a higher degree of characteristics;
• The profile height is selected taking into account the slope of the roof, that is, the greater the angle, the lower the profile height required during installation;
• The shape of the profile that the supporting corrugated sheet has plays an important role in determining the degree of rigidity and strength of the profiled sheet.

High-quality load-bearing corrugated flooring allows you to create a structure with high degree reliability. At the same time, the material is resistant to temperature changes, chemical and mechanical stress. The service life of sheets coated with pural is more than 50 years, but it is important correct installation. Compliance with fastening technology metal elements allows you to create not only practical covering, but also provide good sound insulation.

Before choosing a metal sheet, it is important to calculate all the characteristics, the required load-bearing capacity of the elements, as well as other parameters. After this you can select optimal material, which is marked “H”, indicating the load-bearing type of sheet. This approach allows you to create reliable design roof or ceilings, roof decking or other structure.

The optimal load-bearing capacity of corrugated sheets is an essential parameter that is always taken into account when using sheets in construction. High-quality, reliable and versatile load-bearing corrugated sheeting meets all necessary requirements and standards. The cost of this type is quite high compared to products with lower characteristics. Moreover, this profiled sheet is more affordable than other materials, for example, metal tiles, for arranging a roof or floors.

Durable load-bearing corrugated sheeting is presented in wide range. Various brands differ in load-bearing capacity, technical characteristics and design features. That is why, before making a choice, it is important to make an accurate calculation of the required parameters, thanks to which the load-bearing corrugated flooring will ensure the quality of the structure.

The load-bearing capacity of a profiled sheet is the primary characteristic of the material. Since it is used in the construction industry, its load-bearing capacity characterizes the possible load of the entire structure. If earlier an increase in the strength properties of corrugated sheets was achieved due to the thickness of the surface, now the material consumption has decreased, but the strength and reliability of the products have not been affected.

Today there is great amount types of corrugated sheets. Each type of material has its own specific use. One of the most popular in the modern construction industry has become a load-bearing profiled sheet. Its scope of application is quite wide.

When installing a roof, load-bearing corrugated sheeting is often used to construct floors.

If you've been paying attention, there are numerous shopping centers, large industrial workshops and warehouses have in their design ceilings made of powerful wavy sheets - this is corrugated sheeting. It is made from rolled roofing steel or sheet type. It is processed on specialized machines. After processing, the flat surface becomes corrugated (sometimes wavy).

Load bearing capacity

As for the load-bearing capacity of corrugated board, its indicator is much higher than that of sheet steel with the same thickness. Thus, an increase in the wave height of the sheet will increase the load-bearing capacity of the material.

Eg, maximum load corrugated sheeting (C10-1200-0.6) per 1 sq. m. at a step of 1 m., will be equal to 86 kg. Profiled sheet NS44-1000-0.7 at a distance of 3.5 m will withstand a load of 182 kg per 1 m2. The indicators are very significant.

The weight of the sheet profile and its high level of reliability make it possible to use the material for universal tasks.

Scope of application of corrugated sheets

Currently, corrugated sheets are an indispensable material for various construction activities:

1. Corrugated sheeting has found its application as a covering for roofs in any type of construction, from private to industrial. Roofs lined with corrugated sheets differ unique properties such as high strength and reliability, pleasant appearance and durability. The average period of operation is 50 years.
2. The installation of permanent formwork is a process in which a load-bearing profiled sheet is necessarily used.
3. The installation of floors in any structures requires the mandatory use of corrugated sheets.
4. Profiled sheets have found their application as a material for constructing floors between floors.
5. It is also used as a material for constructing wall fencing in various buildings and structures.
6. In addition, the professional sheet is the best option to create a protective structure in the private or industrial construction sector.

The load-bearing corrugated sheet has the following wide range application because it allows you to minimize total time for the construction of an object of any complexity.

It is known that the load-bearing capacity of corrugated sheeting is a load at which the material does not lose the strength of its elements.

Today experts use various schemes calculations: one-, two-, three- and four-span.

In addition, the mandatory calculation of the load-bearing capacity includes the parameter of the width of the structure at the point of contact with the sheet. This figure must be at least 40 mm.

Load capacity calculation

There is a special calculation table with maximum permissible loads for load-bearing profiled sheets.

To calculate the load-bearing capacity, a technique is used to select the grade of corrugated sheet.

Figure 1. Calculation of the load-bearing capacity of a profiled sheet.

A clear calculation of the load-bearing capacity makes it possible to select the material required in all respects.

Example. At the object gable roof, the angle of inclination of which is 35 degrees. Projecting the ramp onto horizontal surface, it turns out that the indicator will be equal to 6 m.

If we summarize the total degree of load of the corrugated sheet, then it includes not only the mass roofing material, but also the intensity of climatic loads (wind, blizzard, snow, etc.).

To find out the weight of the profiled sheet, you need to find out the total area of ​​the roof, including overlaps (per 1 sq. m. - 8.6 kg).

Corrugated sheet in the table

Using Table 1 (Fig. 1), it is possible to calculate the load-bearing capacity of a profiled sheet and determine the type of material.

Figure 2. The ratio of the degree of load-bearing capacity of a corrugated sheet according to the grade of material and the number of spans.

As for the weight of the profiled sheet, this characteristic is very important.

It is necessary not only to calculate transportation, but also to make sure that the structure can withstand the load coming from the sheets themselves.

This table contains information weight characteristics brands of corrugated sheets that are most in demand by customers.

It is worth considering that the profiled sheet can be made from steel different types, and therefore the weight of the material will be slightly different.

The most important characteristic of corrugated sheets is its excellent ability to withstand heavy loads. Table 2 (Fig. 2) shows the relationship between the degree of load-bearing capacity of the corrugated sheet according to the grade of material and the number of spans.

Selecting the required brand of profiled sheet is not so difficult. However, this will allow you to find out which brand of material should be chosen for installing a strong and durable floor.

• Metal profiled sheets are produced in various options, each of which, as a rule, is intended for specific purposes, even non-standard ones. They withstand loads much better than flat ones, since the profiles in this case act as stiffeners.

  The most practical building material available today is load-bearing corrugated sheeting. This universal material, which is suitable for use in any field of construction. This type of profiled sheet is quite often used for the device various floors, experiencing fairly high loads. It is no coincidence that he is called the carrier.

  Very important characteristic the material is the load-bearing capacity. The loads of the corrugated sheet depend on this parameter, from which the structure made of this material is not subject to deformation or destruction.

  Distinctive qualities of the load-bearing profiled sheet

  Like other profiled materials, the load-bearing corrugated sheet has a corrugated surface. The manufacturing technology of this material is as follows: rolled or sheet cold-rolled steel, the thickness of which ranges from 0.5 to 1.00 mm, is passed through a roll forming mill, giving the sheet a profile with additional oblong recesses. The load-bearing capacity of the corrugated sheet is already quite high, and these indentations greatly increase the rigidity of the material.

  

  These sheets have the greatest thickness (for comparison, we note that the average thickness of a simple profiled sheet is 0.5 mm).

  The corrugations form a height of about 6 – 11.4 cm, which also sets these profiled sheets apart from others.

  Using load-bearing profiled sheets for floors is much more profitable than heavy and bulky reinforced concrete slabs.

  On a note

  Note that the average weight of one square meter of metal profile does not exceed eight kilograms.

  Advantages of load-bearing corrugated sheets

  • Unusual reliability at a fairly light weight. The ceiling is made of load-bearing corrugated sheets, unlike concrete floors made of concrete, do not actually exert significant pressure either on the walls of buildings or on the foundation. Thus, as a result of reduced design loads, ease of transportation and easy installation construction becomes cheaper.
  • Low cost of material.
  • Load-bearing corrugated sheeting has high resistance to various kinds influences: moisture, low temperature, wind, snow and mechanical loads, ultraviolet radiation, fireproof.

  Material marking

  Sheets of corrugated sheets are marked with markings that indicate their main purpose. The material about we're talking about in the article, noted in the nomenclature initial letter the words “carrying” - “N”.

  High load-bearing capacity makes it possible to use them to cover low-slope roofs (up to 7°). It should be noted that the thicker the sheets, the more more weight They can withstand a layer of snow. This material is practically indispensable for large roofs, where especially a lot of snow accumulates in winter.

  

  The load-bearing profiled sheet is also actively used when forming interfloor ceilings as formwork. Reinforcement is inserted into it and filled with concrete. This eliminates the need to use additional materials, installation is extremely simplified and costs much less.

  On a note

  The range also includes corrugated sheets brand "NS", that is, load-bearing wall. They differ from load-bearing corrugations in that they have a shorter corrugation height - about 3.3–4.4 cm. Obviously, it is too high load too heavy for them, so they are mainly used for cladding walls and roofs, but not for constructing heavy ceilings.

  For profiled sheets "N" no additional painting is required, since they already have protective layer– zinc or zinc-polymer. Moreover, you can always choose suitable color material, fortunately there is a really wide choice.

  The letter marking is supplemented with a number that indicates the height of the corrugation.

  

  A universal brand of material that can be used in the construction of formwork, interfloor slabs, enclosing elements, and roofing work is load-bearing profiled sheet H57.

  It is designed to withstand significant loads. The distance between the supports can be chosen large enough, and this will not affect the strength of the structure in any way. Corrugated sheeting of this brand is in great demand in fairly snowy areas.

  

  The profile height of 57 cm allows it to withstand severe wind loads. In addition, bearing profiled sheets H57 can cover spans up to 3 m. Many builders prefer it because optimal combination price/quality, sheet widths and their load-bearing characteristics. It is no coincidence that during the construction of this or that object, the basis of most calculations by definition ultimate loads This is exactly the material.

  How to calculate the load-bearing capacity of corrugated sheets

  This setting depends on permissible loads, the impact of which does not lead to deformations, ruptures or other damage to the structure made of corrugated sheets.

  

  Limit values ​​are also determined by laying patterns and span widths. The most popular are one-, two-, three- and four-span laying schemes.

  The width of the spans can vary from one to six meters. In this case, the extreme support at the point of interface with load-bearing corrugated sheeting should be wider than 40 mm, and medium ones should be wider than 80 mm.

  For load-bearing profiled sheets with a corrugation height of at least 100 mm and a support spacing of 6 m, only two- and single-span flooring schemes are possible, since the length of the profiles is usually no more than 12.5 m (according to transportation conditions, as well as installation technology).

  

  When choosing a material, use tables of the load-bearing capacity of corrugated sheets, which are calculated for profiles of a specific thickness. If you need to work with sheets of a different width, then the desired table value is multiplied by the ratio of the thickness of the profile from the table and the thickness of the one used.

  Calculation example

  Let's say construction gable roof, having a slope of 35°, and a slope projection of 6 m, occurs in the Moscow region.
