Profiled roof which one to choose

metallic coating roofs of private homes is becoming more popular, especially since the material is produced in various forms and, thanks to modern technology, it is constantly being upgraded.Therefore, many consumers there is a fair question - profiled roof which one to choose?This roofing material has excellent aesthetic and performance characteristics, is capable of not only reliably hide the building from rain and wind, but also to transform his appearance.

Profiled roof which one to choose

sheeting for roofs which to choose

sheeting produced in different colors and can also be of different thickness and configuration sheets.Due to the fact that the roofing sheets are given to dimensions that allow you to completely cover the length of the roof, from the ridge to the eaves, it is much easier to mount on a truss system, for example, than the familiar traditional slate.In addition, the material is not too heavy, but thanks to a special protective coating and polymer film deposited on top, it will last quite a long time.

In many respects profiled favorably with other roofing

Qualitative professional flooring increasing preference in the selection of roofing materialsresidential buildings, since it has a lot of positive qualities, which can not "boast" of other coverage.These advantages include:

  • first thing that always worries many customers - is the price of the material.It is because corrugated board is available for almost any family, it is increasingly stops selection when choosing the material for the roof.
  • extensive range of colors produced sheets allows you to choose exactly the shade of the coating to be flawless for the harmonious exterior design of a private house.
  • sheeting produced in sheets up to twelve-length, which allows mounting it on the roof to make the minimum number of joints on the slope, or even completely abandon the cross-docking.
  • small specific weight of the material, the simplicity and clarity of installation allows you to perform roofing work on their own with the assistance of only one assistant, who will feed sheets to the height of the roof.
  • consumers are provided with a choice of sheet elevation height - depending on the angle of the ramp slope is planned.
  • In addition, it is possible to choose a different composition topcoat sheeting.The coating may be applied by different techniques, and, accordingly, vary the quality and duration of operation, of course, the cost of material.
  • Another important advantage of corrugated board - is ecological cleanliness of the whole complex materials used in its production.Roofs made of corrugated board, regardless of the duration of use, is not capable of causing harm to the environment.It is also important that the material - non-flammable.

Classification corrugated

Decking is different in many ways , but primarily draws attention to the type of profile

Profiled differ in many ways, but primarily draws attention to the type of profile

Nowadays, manufacturers offer different types of corrugated board, designed for specific applications in the construction practice.However, some of the types, due to its characteristics, can be regarded as almost universal, and used for a variety of purposes.

To determine the choice of material, which is well suited for roofing, it is necessary to consider all the main types of corrugated board, as they are very often used interchangeably.

When considering a particular type of profiled sheet, should pay attention to his marking - it consists of several alphanumeric symbols for its purpose and basic parameters.

Letter designations in marking

first letter in the marking strength determines the quality of the material and substantive scope of application:

  • «H» - this is the most durable corrugated sheets.In this case the letter "N" indicates that it is - a carrier type sheeting.This material has the greatest height of a wave (corrugation), with the additional grooves in its lower part - they impart improved rigidity of the sheets.
Carrier profiled ( N ) features a large wave height , the increased thickness of the metal , special longitudinal grooves that act as additional stiffeners

profiled carrier (H) features a large wave height, the increased thickness of the metal, special longitudinal grooves playing

as additional stiffeners Besides carrying corrugated board differs from most other forms of thicker sheet metal.Therefore, it is used for roofing of residential buildings, construction of walls and roofs of large sheds, fences, manufacture of large containers, construction of production halls, warehouses, garages, gates and other structures, which should have a high mechanical strength, reliability, durability in use.

  • «NA" - a "carrier-to-wall" profile material, and it can be safely called almost universal, since it is used for a variety of purposes.This kind of corrugated different middle-metal thickness and the height of waves.
Bearing - wall corrugated model (HC ) are characterized by high flexibility

carrier-wall model of corrugated board (HC) are characterized by high flexibility

applied the material for the construction and cladding, Roofing of his erect fences, sheds, other household, industrial, and utility construction, made gates andgoal.According to their operating characteristics similar type of corrugated board can be called intermediate between the carrier and the wall materials, but the cost of it is much lower than that of the carrier.

  • «C» - wall corrugated board.It is used for the construction of light hozpostroek, cladding residential buildings over the insulation layer, for the manufacture of brick gates, fences and other structures.

Wave height he is low, therefore, the strength and quality in the transverse bending too low.For the production of many models use the thinnest steel, and it is not surprising that the cost of such material is too small.

Some popular types of corrugated board of "C" category

few popular types of corrugated board from the category "C»

However, many of the models corrugated their category "C" is also quite suitable for roofing.

  • «MP" - one occurring corrugated type that has good versatility and is ideal for roofing and walling hozpostroek, and besides - is used in the production of sandwich panels.What is each of its modifications, you can learn from the alphanumeric labeling.

One of the most widely used type of corrugated board - MP- 20

One of the most widely used type of corrugated board - MP-20

Galvanized profiled MP used to cover pitched roofs, walls in industrial areas, as well as suspended ceilings.This type of material is not only in the galvanized form, but also with a polymer coating.

«MP» -proflist is available in three variations - a type "A", "B" and «R».

example, profiled "MP-R» is intended for roofing and types "A" and "B" are more suitable for wall cladding and fencing.Type «R» is different from the "A" and "B" dimensions of the corrugations, in particular, in that the base has a smaller wavelength, and the distance between waves - wider, while in the wall sheets is not the case.According to this profile will be easier to drain storm water flows.

Furthermore, thanks to the parameters roof type «R» wall steel sheet superior in bending strength and can withstand high static load.Type "A" and "B", in turn, it is better to resist the wind dynamic effects.Wall

types of corrugated board are different from each other in that "A" is produced with a protective coating on the front side only and the coating of "B" type - specifies the time of ordering.Therefore, in the second embodiment, color layers may be completely absent or are applied to one or both sides of the sheet.

Profiled " MP" - the difference between the wall ( "A" and "B" ) and the roof , " the R " ) profile

Profiled "MP" - the difference between the wall ( "A" and "B") and the roof, "the R") profile

Profiled "MP" is made with a wave height of corrugations in 18 or 20 mm.

Digital designation labeling

Thus, the product label for the letter designation followed by numerical values ​​that give the necessary information:

  • The first number indicates the wave height in millimeters.
  • second numeric value indicates the thickness of the steel sheet, which is made of corrugated board - this option is also given in millimeters.
  • third group of numbers provides useful information on the width of the sheet, in millimeters, that is, taking into account the overlap of the waves when paving.This parameter is always slightly less than the actual dimensions of the sheet, it should be remembered that, for example, the organization of transportation or storage of the material.
  • sheet length can not be specified, as when ordering material for specific needs, it can be any, on demand and the ability of producers.However, often in the price lists still given limit length in millimeters.For example, the last group of numbers can stand 12000.

Thus, the corrugated markings may look like this:

S10-0,5-1100 - it says that the profiled wall type, having a height of waves10 mm, made of a sheet 0.5 mm thick with a useful width of 1,100 mm.

Another example of labeling:

MP-18-0,7-1000V - is profiled with a wave height of 18 mm, made of steel sheet thickness of 0.7 mm, useful width of 1000 mm, made of galvanized steel without a coating,but it can be applied on demand from one or both sides.

Knowing how to read these values, it will be much easier to find the necessary modifications profiled.

sheet thickness, wave height, weight corrugated

When choosing a professional flooring defines the parameters will be the wave height and thickness of the metal sheet

When selecting a professional flooring defines the parameters will be the wave height and thickness of the metal sheet

necessary to illuminate the question of what can be the minimum and maximum thickness of the metal sheetfrom which it is produced corrugated board, as well as some weight can have the sheets of roofing material - this is extremely important especially for the roof structure.

  • thickness of the metal sheet is:

- in species "N", "NA" and "C" may vary from 0.4 mm to 1.2 mm;

- «MP-R» - from 0.4 to 0.8 mm;

- «MP-A" and "IP-B" - about 0.4 to 0.7 mm.

This parameter directly depends on the strength of the material, its resistance to the characteristic roof loads - wind and snow.

  • is necessary to choose the height of the wave corrugated board, as of this parameter also depends on the stiffness of the material and the reliability of its fit and fastening to the sheathing roof system.Typically used for roofing profiled with a wave height of not less than 18 mm, and up to 60 ÷ 75 mm.However, the upper value can not be considered limiting, you can use a higher stuff, but the only question is the feasibility of this approach.
Various wave height profiles sheeting

Various wave height profiles sheeting

Wave height influences not only the strength of the material, but also on the quality of water drainage from the roof in the rain.Profiled sheets "NA" and "H" with grooves in the bottom of the wave, are more resistant to various stresses, so choosing a roofing material, it is recommended to give preference to them.

We must not forget that during the winter period on the roof can be formed accumulation of snow, which coating must withstand.In addition, the roof should withstand the weight of a person, since she did not have time to climb for various reasons.

The table below shows the main types of corrugated board with the indication of specific areas of application:
