There are many building materials on the construction market, as well as roofing.
Of course, they differ in quality and price, in general, there is plenty to choose from. Overlapping the roof, two types of steel sheet roofing are often used. The service life of these materials ranges from 20 to 60 years.
There are not many differences, but they are, and one of them is the price difference.
Probably everyone has already understood what it is about and in the article we will analyze the purpose and quality of materials: corrugated board and metal roofing and the better to cover the roof with corrugated board or metal tiles.
This material has different names: professional sheet, corrugated sheet, profile.
This material is made from roofing steel , which is cold rolled. Each sheet has a wavy, trapezoidal or rectangular shape. To give the roof strength, it is galvanized or coated with a polymer coating.
Profiled sheeting is divided into three types:
Steel is also used in its production which is cold rolled.
The thickness of the metal tile sheet is slightly thinner than that of the corrugated board, the pattern also has a difference.
The metal tile has a pattern that imitates ceramic tiles and this differs from the corrugated board. For this reason, it has a similar pattern.
Metal tiles are produced with a large number of polymer coatings, such a coating performs a protective function.
Weight and thickness of materials
To make sheets of corrugated board , steel with a thickness of 0.5 to 1.2 mm is used.
For the manufacture of metal tiles , sheets with a thickness of 0.
4 to 0.6 mm are used.
Several layers of coating are applied to the sheet of metal tile, therefore it has a greater thickness than the corrugated board, but the metal at the profiled sheet is still thicker.
The weight of the corrugated board is 3.6 -11 kg / m2, the weight of the metal tile is 3.
8 -7 kg / m2. Let's consider the parameters on specific brands:
In the examples, we presented the parameters for each of the materials.None of them can be called heavy, so they do not need a reinforced rafter structure.
The professional sheet is first galvanized or aluzinc is applied (it gives extra durability).
Aluzinc material manufactured by Arcelor. Zinc, aluminum and silicon are added to this coating.
This coating is not as flexible as zinc.
The profiled sheeting is covered with a primer and passivation layer and a polymer coating is made.
On the cut, the metal tile has many layers. At the initial stage, the metal sheet is galvanized on both sides, then a passivating film of aluminum is applied. Then a layer of polymer is primed and applied, the final layer is varnish.
There are many polymer coatings for metal tiles and for profiled sheets.
Let's highlight the most popular polymer coatings:
the service life and durability of materials are influenced by some points.
For protection, a polymer layer is applied to the materials, it just increases the service life by about ten years.
Metal tiles, which have this coating, will serve longer than galvanized corrugated board.
When comparing corrugated board with polymer coating, and metal roofing, it is necessary to take into account what the polymer coating will be.
The plastisol coating is considered the most durable (it lasts from 60-70 years), while the polyurethane coating lasts no more than 30-40 years.
Now let's talk about the quality of galvanized steel.
Steel treated with zinc will last ten years if the zinc coating is no more than 140g / m2. If the zinc coating is 245 g / m2, then such a product will last a little longer.
Unfortunately, Russian producers save zinc during production, in contrast to European producers.
If the sheet of corrugated board is thicker, then it will have a longer service life, in contrast to a thin sheet of metal.
The conclusion is that both materials are reliable and durable. The average service life of a metal tile is from 20 to 40 years, and from a corrugated board from 30 to 40 years.
Before choosing this or that material, consider the reliability of the manufacturer.
Sheets of corrugated board have waves, they can be:
The parameters of the corrugated board:
The width of the sheet is 1-1.2 m
The length of the sheet is up to 12 meters
The profile has a height of 8 -45 mm
Metal tiles are made:
Width 1.16 - 1.18 m
Its length is 0.4 - 0.
The height ranges from 22 to 25 cm.
Wave parameters are from 300 to 400 mm.
As we said, earlier the metal tile has a pattern that imitates ceramic tiles and it is more complex than on corrugated sheets.
It is easiest to work with corrugated board. It is easier to pick it up under the roof slope than metal tiles.
Due to the simplicity of the profile, it is easier to work with corrugated board.
With the help of long sheets of corrugated board and with the help of a construction team, you will quickly cover the roof, you can handle the sheets of metal tiles yourself, since its sheet has less weight than a sheet of corrugated board.
These types of roofs do not burn out completely, since under many, coverings are metal.
Does not absorb noise when laying such a roof, if desired you can additionally make noise insulation.
When it rains, the noise from the drops will be very audible, of course some people may be annoyed by this, but there are people who like to listen to the sound of rain.
Mineral wool is an excellent material for thermal insulation and sound insulation.
The metal tile wins the beauty of the profiled sheet.
The roof of your house will look more interesting with it.
The profiled sheet is easier to fit under the roof slope, but metal tiles are problematic.
We hope that in this article you will gather a lot of interesting and useful information for yourself, and you will make the right choice.
We wish you good luck and inspiration!
