Shed) or a house, people are puzzled, what should they build from?
In the construction market, there are many building materials, as well as roofing.
Of course, they have differences in quality and price, in general, there are plenty to choose from. When covering the roof, two types of steel sheets 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 difference in price.
Probably, everyone already understood what it was about and in the article we will analyze the purpose and qualities: and what is the best way to cover the roof or.
This material has different names: profiled sheet, corrugated sheet, profile.
There are many polymer coatings for metal tiles and profiled sheets.
Let's highlight the most popular polymer coatings:
- The polyester layer is 25 microns;
- The matte polyester layer is 35 microns (Teflon additive);
- 50 microns is a pural layer (it has a silk structure);
- Plastisol layer is 100-200 microns (cold resistant);
- PVDF layer -300 microns (UV resistant)
Service life and durability
Several points affect the service life and durability of materials.
For protection, a polymer layer is applied to the materials, it just increases the service life by about ten years.
Which has this coating, will last longer than galvanized corrugated board.
When comparing corrugated board with a polymer coating, and a metal tile, it is necessary to take into account what the polymer coating will be like. 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, unlike European producers. If the corrugated sheet is thicker, then it will have a longer service life, unlike a thin sheet of metal.
The conclusion will be that both materials are reliable and durable. The average service life of a metal tile is from 20 to 40 years, and that of a corrugated board is from 30 to 40 years.
Before choosing one or another material, consider the reliability of the manufacturer.
Material dimensions
Sheets of corrugated board have waves, they can be:
- trapezoidal;
- rectangular;
- wavy.
Profiled sheet parameters:
Sheet width is 1-1.2m
Sheet length 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 - 0.6 m
Height ranges from 22 to 25 cm.
Wave parameters range from 300 to 400 mm.
As we said, earlier the metal tile has a pattern that imitates ceramic and it is more complicated than on sheets of corrugated board.
Mounting materials
Profiled sheets are the easiest to work with. It's easier to pick it up
