Both in the city and outside it, you have probably seen roofs, fences, gates made of corrugated metal. This convenient and aesthetically attractive material has been used in construction for a long time. And every year it is becoming more and more popular. Now manufacturers offer various types of corrugated board, each of which is designed for specific purposes.
The variety of brands is surprising, because at first glance the material is very simple and concise. In order to figure out which type you need for construction, you need to find out the characteristics of each of them.
Types of material and its differences
For different purposes, different grades of material are produced. When purchasing corrugated board, first of all, pay attention to the letter with which it is marked. Then in the future there will be no doubt which corrugated board is better or worse than the others.
- H - the most durable type of profiled sheets. The letter in this case means "bearing". Profile for corrugated board has the largest thickness, corrugation height and additional grooves, giving increased rigidity. That is why it is used in the installation of powerful ceilings, fixed formwork, for the construction of hangars, heavy containers, strong fences, garages, workshops, warehouses and other things. However, it can also be used for cladding walls, roofs, for the manufacture of gates and gates. It will give amazing strength and durability to structures.
- NS - means that this type belongs to the "bearing-wall". That is, the brand can be called universal. It usually has an average sheet thickness and corrugation height. This type, like the previous corrugated board - the types of which have increased rigidity, load-bearing - wall sheet can be used for ceilings, as well as for finishing walls, roofing and much more.
- C - belongs to the category of "wall", therefore it is most often used for wall cladding, often with preliminary laying of insulation under it. This is the most elegant variety, with sheets of medium and small thickness and corrugation height. However, the strength of the material allows it to be used for roofing, wall decoration, making fences and other things.
We continue to describe corrugated board - types of material. After the letter in the marking of the material, as a rule, there are numbers. They mean the height of the wave at the sheet in millimeters.
For example, C-8, where the letter means "wall", and the number indicates an eight-millimeter wave height. The thickness of the elements of this brand ranges from 0.4mm to 0.8mm.
Note! Although, in this category, all types are successful - corrugated board with these data is considered one of the most popular. Thanks to its medium profile thickness and height, it is versatile for almost all types of work. It is suitable for both roofing and wall decoration and the manufacture of floors with medium loads, the construction of garages, fences and other structures.
Thickness, weight and types of profiles
If you have an idea of \u200b\u200bwhat kind of corrugated board is, you can easily select the right brand for specific purposes. To do this, you need to know some characteristics, which are not so many, but they are all important when choosing.
As for the thickness of the material, it ranges from 0.4 mm (for wall-type grades) to 1.2 mm (for load-bearing varieties).
It should be noted that the thickest sheets that can withstand a very large load are used for powerful floors in workshops, hangars, as well as for interfloor floors.
Additional ribs and grooves between the waves of the corrugations enhance the resistance to loads. Naturally, the weight wall corrugated board maximum and reaches 24 kg per square meter, and the wave reaches a height of 114 mm.
Often, builders use it as a fixed formwork. By laying additional reinforcement and pouring concrete mixture, they perform ideally durable and strong structures.
And yet, with high strength, corrugated board can be called one of the lightest building materials.But, the carrier brand can be used for any other purpose. .
Roofing from corrugated board perfectly withstand any load, both the weight of a person and the mass of snow cover of any thickness.
He is also not afraid of mechanical influences, and thanks to galvanization and polymer coating, he is not afraid of water or temperature changes. Transportation, as well as installation, is extremely simple and fast.
Analyzing other types of corrugated board, one can also note the versatility of load-bearing wall grades. Sheet weight ranges from 7 kg to 14.5 kg per square meter. This is the average weight among all categories.
The same golden mean is also observed in the sheet thickness (from 0.5 to 0.8 mm) and wave height (from 8 mm). Where huge surface loads are not expected, it is quite possible to use elements of this type.
And, finally, the lightest type (from 4.5 kg per square meter), used mainly as roofing and wall cladding, is grade C wall profiled sheet. Sheet thickness starts from 0.4 mm, weight - from 4.5 kg per square meter, wave height - from 8 mm.
Note! If your roof does not have a very large area and rather steep slopes (from 7 ° and steeper), this material will suit you perfectly. It is also ideal for wall cladding, as well as for the construction of a fence or fences. This corrugated board - the texture of which creates a pleasant impression and a neat appearance, in fact, is used very willingly in private construction.
Most Popular Brands
Among the huge assortment, nevertheless, there are the most popular types of corrugated board.There is a certain classification of corrugated board, in which each brand serves a specific purpose.
- H-60. Sheet thickness 0.5 mm - 0.9 mm, weight 5 kg - 12 kg / m², wave height 60 mm. It is used mainly for the installation of load-bearing systems, as well as for durable roofing, good for building garages, fences, fences.
- H-75. Sheet thickness 0.7 - 1.0 mm, weight 9.2 - 12.0 kg / m², wave height 75 mm. It is considered a universal brand used for almost any purpose. It can perform both load-bearing and protective functions. Perfectly is suitable for installation of overlappings and as roofing material.
- H-114. The most powerful variety in all categories. Sheet thickness 0.7 - 1.2 mm, weight 10.2 - 14.5 kg / m², wave height 114 mm. Reinforced with additional grooves that increase power. The spectacular texture of the corrugated board not only protects, but also gives a noble look. And, although it is designed for the most durable structures, it can be used for any purpose.
- H-153. It is also called European standard. Sheet thickness 0.7 - 1.5mm, weight 10.3 - 21.5kg / m², wave height 153mm. It is popular for the possibility of using it on coverings with a lathing step of up to 9m. It is used both for overlappings, and for roofing works.
- H-158. It is in demand, as it has the highest wave (158mm), and the ability to use it on surfaces with a step of up to 9m. Has the maximum durability and rigidity of sheets. Ideal for both load-bearing and other types of structures.
Often the question arises, what is the best corrugated board to buy? As we understand, among its varieties, although there are the most popular, there is no clear distinction between good and bad.
The principle of its production is the same - profiled sheets of galvanized steel, covered with a layer of protection against external influences.
Coatings differ in their protective composition.
- Zinc coating is considered the simplest and most inexpensive. However, and the most short-lived.
- A slightly more durable coating is made by adding aluminum with silicon to the composition.
- Polyester coating is already a more effective and durable option. It is possible to choose the desired color of the coating.
- Polyester with Teflon. Makes the coating stronger and allows a large choice of colors.

- The PVDF layer creates ideal protection against any impact.
