Today, many people are accustomed to thinking of corrugated board only as a roofing material. But there are many of its types, which differ in purpose, geometric and operational characteristics, material of manufacture. In our article, we will tell you whether it is possible to use all existing types for roofing and how to choose corrugated roofing to protect the house from natural influences and emphasize its dignity.
Characteristics of corrugated board
Before making a choice roofing profile for installation of corrugated board on the roof, I would like to dwell a little on the characteristics of this building material.
There are many types of metal corrugated board (profile):
- galvanized, uncoated and polymer coated;
- steel (made of ferrous metal);
- non-ferrous metal profile (copper or aluminum);
- special (bent, with textured embossing, rolled, perforated).
Each type of profile has its own geometric parameters that are important in the selection and construction:
- height;
- full and useful width;
- thickness;
- moment of inertia.
In addition, it is characterized by a profile and performance indicators:
- base material thickness;
- type of coverage (if present).
Accordingly, with a wide characteristic, the profile has a wide range of applications:
- bearing profile;
- for facades;
- formwork profile;
- special profile.
Depending on the type of materials used and geometric indicators, before you fix the corrugated board to the roof with your own hands, find out where it is best to use it.
Attention! Without departing from the description of the classification and type of profile, I immediately want to focus on the fact that the roofing profile can be used for facade work. And it is impossible to use a facade profile for a roof device.
Since the façade profile has a narrow part of the lower section, the throughput of rainwater is therefore reduced.
Another important point. Basically, all types of corrugated roofing are distinguished by the presence of a capillary groove, which prevents rain from flowing under the roof.
When water enters under the overlap, the groove facilitates its removal into the gutter, thereby eliminating the capillary effect. There is no such groove on the facade materials.
In the roofing material, the groove can also be different. It all depends on what rolling equipment the corrugated board was made on.
On high-quality roofing material, when cutting, the capillary groove does not bend, its beginning comes from the ridge, and it ends at the gutter eaves.
In inexpensive types of roofing profile, flattening of the groove is observed when cutting, while the section of the groove is violated, and the original meaning of the groove loses its meaning.
This point is very important when choosing a profile. It is impossible to visually determine it, so you should decide on the manufacturer of the material, find out who has proven itself better in the roofing materials market.
Selection Options
The presence or absence of a section is far from the first and not the last moment that you need to pay attention to when choosing.
Take an interest in these points:
- marking;
- appearance;
- price;
- type of polymer coating.
When choosing a corrugated roof, colors also matter.
Let's take it in order:
- Marking. From the many profile markings, you have to choose the right one. The presence of the letter C in the marking means that the profile is wall. The order of the numbers shows the wave height and useful width (for example, C 21-1000).
Attention. For roofing, manufacturers recommend using a profile marked H and a height of at least 20mm.
In addition, you can find out on the basis of which the corrugated board was made - GOST (a) or TU. Of course, subject to state standards, the profile will have better characteristics.Pay attention to whether the products have a certificate.
- Appearance. By purchasing initially low-quality material, you have to overpay. Since after a short time the profile may crack and you will have to change it. When choosing, be sure to pay attention to the appearance. The surface of the metal profile must be smooth. The presence of roughness and small cracks indicates a low quality product. If the material has a color version, pay attention to the surface of the paint, if there is any peeling.
You can also check the profile for strength. With slight bending, high-quality material does not break, but returns to its original shape. With strong efforts, the bending shape should remain.
Advice. If the appearance of the roofing seems flawless to you. All the same, it would not hurt to learn about the profile of a certain type of feedback from consumers.
Do not think that foreign consumer roofing material is more reliable. There are many domestic technologies, according to which a better and cheaper product is produced.
- Price. The price indicator may depend on the thickness of the profile sheet, the type of polymer coating, the policy of the seller. In general, it is not in vain that construction companies use this material in most cases. It embodies an excellent ratio of high quality and affordable price.
If you want to choose a profile whose cost is not high, then you have to study the price list of several stores. Since on the same kind of profile. The price may vary slightly. It's understandable that the pricing policy of trading firms in each city is different.
- Profiled sheeting.To give the roofing material higher physical and chemical properties, including resistance to corrosion, a zinc coating is applied to it. The longer the period of use of corrugated board is expected and the environment is more aggressive, the greater should be the thickness of the coating.
Zinc coating performs protective functions. That is, it prevents the partial destruction of the base material. It has no decorative purpose.
To achieve the color of corrugated roofing, polymer coatings are used, with preliminary passivation and priming.
The highest quality profile is considered to be coated with matte polyester, plain polyester, plastisol. You can familiarize yourself with the color scheme of the coating on the color map of any trading company and make a choice based on your own taste and the exterior of the house.
Popularity with consumers
Very often, a modern consumer prefers galvanized corrugated board, which is a steel sheet made by profiling.
Such popularity is caused by a combination of structural rigidity, low weight, high performance and affordable price.
The stiffening ribs of this material prevent the deformation process that can occur from heavy loads, such as snow cover. The galvanized profile differs in durability and durability.
Knowing the dimensions of the roof and using our advice, the choice of corrugated board for you will not be particularly difficult. Do not forget that the quality of the roof depends not only on the quality of the roofing material and the way it is laid, but also on your choice!
Therefore, treat it with full responsibility and a serious attitude to the matter. Fortunately, the range of profile coatings allows you to consider several options.
