Profiled on the roof - what to choose? Technical characteristics and reviews

Usually, when choosing roofing materials, they try to find a quality and inexpensive option. Often people want to buy exactly profiled roofing. Which one to choose, can be determined very easily. It at a small cost differs high strength, is durable. It is also highly appreciated due to the fact that all phases of the cold rolling procedure pass during manufacturing.

General characteristics

Many manufacturers offer their own configurations and varieties, which has profiled roofing. What to choose, you need to determine yourself, as this is the buyer's task. It is necessary to choose the most high-quality options, which have good properties and high performance characteristics. There are such varieties of corrugated board, which can be attributed to the class of materials for the roof:

1. Galvanized profile, which does not have a special polymer coating. It has the lowest cost. You can determine the difference by about 40%, if compared with materials that have paintwork. It is used as awnings, as well as when necessary to build garages and other farm buildings, and not for living quarters.
2. Profiled sheeting made of black steel. This material also has no protective coating.
3. Material of non-ferrous metals. Can be made both from copper, and from aluminum.
4. Specially adapted corrugated roofing, which is very easy to choose, because it is designed for roofing structures and has the necessary protective coating. Can have the color, shape and size that the client wants.

Features of corrugated board

Each type of corrugated board from the above has its own characteristics. They are distinguished by the height and width of each sheet, the possibility of correcting these parameters, the thickness of the coating, which is an important and decisive perimeter, determining the cost and positive qualities that specific sheets of corrugated roofing have.

For the construction of the roof, it is possible to successfully apply wall and facade corrugated board, in addition to the carrier, as all these profiles withstand the necessary load, which is assigned to the entire roof structure. Bearing corrugated roofing, which is very easy to pick, differs form sheets, as each of them has a capillary groove. This helps to quickly and effectively remove rain and melt water from the roof. It should be remembered, the facade profile does not have such a groove.

Price and quality

When the corrugated roof is chosen, the prices should be coordinated with this particular feature, since the presence of a special groove allows the coating to be carried out without any complications. Usually this material costs from 200 rubles. It must be remembered that a special groove for draining water can not bend, that is, it must be made of high-quality material. Usually it starts from the ridge, and its end falls on the edge of the eaves. If you choose a cheap option, there is a risk of flattening the groove, which makes it an extra detail on the roof.

Types of corrugated board suitable for roof construction

• RN-20. This kind of corrugated board can be used not only for roofing works, but also for fences, walls and other structures, which indicates the high quality and reliability of this material. In these panels there is a groove that serves to ensure optimal drainage of water from the surface. When this installation is installed, a crate with a step of 80 cm is required. It should be remembered that the working width of this sheet is exactly 110 cm. Such parameters determine the dimensions of the corrugated board for the roof.
• C-21. This profile has been subjected to many researches, therefore experts say that it is suitable for almost any roof, which can withstand even a considerable load. If the flooring is carried out according to all the rules, an excellent protection against all kinds of precipitation is guaranteed. The step of the crate must be exactly 80 cm. Thus, the dimensions of the corrugated board for the roof are determined.
• HC-35, 44. These profiles are used not only for the roof, but also for the need to create a strong fence. They are distinguished by bright indicators of strength and rigidity. The second of these options has additional stiffeners, which increases its quality score and makes it more visible among other options. Often developers say that this is the best corrugated board.

Basic selection criteria

1. Marking. Must be written in large letters and numbers. They display data on all the main characteristics of a specific type of corrugated board, so they should be paid attention and quickly navigate if you need a quick choice.
2. Appearance. To determine the quality index, you should focus on the smoothness and smoothness of the material. Profiled sheeting for the roof of the price is different, approximately in the area from 170 rubles to 500 rubles apiece. It should not have noticeable dents and other defects. If there is paint coating, it should be absolutely smooth, the shade on all faces is the same. Be sure to check that there are no rips or any chips.
3. The cost. If the material can be called good or high quality, the price will not be too low, and there is practically no possibility of any shares or discounts. There is a possibility that the cost will be quite affordable or even attractive, so do not rely solely on expensive models.
4. Type of coating. Galvanized corrugated board is evaluated only in the presence of polymer coating, but materials without it usually do not have a high durability index. The paint layer is different in thickness or shade, which affects the decision to choose a particular material for the roof.

Marking of corrugated board

It should be noted that from materials for creating a roof covering, you can select only those that have the letters C and H in the name. This guarantees the suitability of a particular product to participate in the creation of a roofing structure. The second option is preferable, since it has the highest degree of rigidity. If you analyze the order of numerical values in the marking, you can accurately determine the height of the wave, as well as the width of each individual module.

A high-quality roofing material can only be considered as a covering whose wave height is not less than 20 mm. The weight of the corrugated board usually fluctuates around 4-5 kg. It is necessary to consider additionally TU or GOST, according to which the corrugated board production took place, and also to compare the real properties of the material with the planned manufacturer. To verify the authenticity and quality of the product, you should read its certificate.

Appearance

In addition to the color, shade and visual effect that the finishing of the corrugated board has, one should pay attention to its quality, since several years after installation it will be of decisive importance. All the properties of the material need to be studied in detail, so that after 5 years, do not have to dismantle and re-cover. Pay attention to the weight of the corrugated board. It should not be less than 4 kg.

How to identify shortcomings?

If the profile is bad, there will be fine cracks on it, the paint can peel off, and sometimes noticeable flaws or manufacturing defects can be seen. If at least one of these shortcomings is found, such material is not necessary to acquire, since in the course of time its appearance will only worsen. If you slightly bend the corrugated board, you can determine its quality.

A good product will instantly unbend, and when using poor-quality materials, the profile may be delayed for some time in an artificially given position. Also, if you independently bend the site back to its original position, the optimal material will not show any traces of impact, and a defective material may leave a small dent, which will immediately protect yourself from the purchase of unsuitable products.
