This type of material is very popular. This is due to its relative cheap and simplicity of manufacture. Flat sheets are perfectly suitable for the construction of fences, fences and roof coating. The construction goods market provided many types of their varieties.
Production of asbestos-cement sheets of flat slate
For the manufacture uses water and cement. To give greater bending strength, 10% asbestos is added. In some cases, the sheet is a thin metal plate, which increases its strength and preservation of geometry several times. Recently, silicate paint is applied to slate. It increases its elasticity and gives additional protection. Such slate is more resistant to change temperatures and humidity, and the service life increases by 5-10 years.
Types of asbestos-cement sheets of flat slate
There is unfoldable (NP) and a pressed (P) kind of flat sheets. The surface of them can be flat or embossed. Pressed have a density of 1600 to 1700 kg / m3. Unpressed possess density of at least 1800 kg / m3, stronger, but have limited elasticity. The advantages of flat sheets should be attributed:
- They have a smaller area in comparison with wavy, which leads to a decrease in mass and price.
- It's easier to trim and customize for the required size.
- It can be fixed to the base anywhere having different dimensions.
There are various sizes in construction, but it is worth highlight the most popular:
- 6 mm, used for finishing the outer part of the houses, bearing walls and floors. Size 1500 per 1000 mm has a weight of 17.7 or 19.7 kg. Price indicator within 200-400 rubles.
- 8 mm, has a better combination of price and quality, which makes it the most popular and in demand. The size of 1500 per 1000 mm has a weight of 23.3 or 26 kg. The average price is 350-600 rubles.
- 10 mm, well suited for the construction of fences and fences, as the base of the roof and in the form of partitions. The size of 1500 per 1000 mm has a weight of 29 or 32 kg. Price 550-800 rubles.
Weight depends on its density. The pressed view is noticeably harder. Prices are approximate and can differ significantly in some manufacturers. The price of slate laying ranges within 150-300 rubles.
Calculation of a flat slate material
To determine the desired amount, it is worth doing simple mathematical manipulations. The length of the building is divided into the width of the sheet, 10% is added to the resulting number. So we will learn the number of one row. Further, the length of the roof slide is divided by the length of the sheet and is added 10%. This number will indicate the number of rows. It remains only to multiply the amount of slate in one row on the number of rows themselves. And, ultimately, the obtained value is multiplied by the number of skates (if they are the same sizes).
Terms of operation
The duration of operation depends on various weather and climatic factors. Under ideal conditions, such a slate is able to serve 25-30 years. This period can be reduced to 10 years, with high humidity and frequent temperature differences.
