Flat slate is produced in the form of sheets with a thickness of 6 to 10 mm, a length of 2 to 3.6 m and a width of 1.2 to 1.5 m.This dimensions are certainly too large, so the fences are made either from the already received scraps after roof structures, or sawing whole sheets.

Pressed and non-pressed slate is produced. Their characteristics differ markedly:

  • In pressing the material, the strength reaches 23 MPa, and in unpressed ones. Only 18 MPa, respectively, for the construction of high beds, for example, you need to use the first option;
  • Pressed slate lasts longer, with such processing the material acquires a density higher than 1.8 g / cm instead of 1.6 g / cm, respectively, the material becomes more durable, less delamination;
  • The impact strength in unpressed is 2 kJ / m, and in compressed. 2.5, this option can withstand more pressure;
  • The resistance to temperature extremes and the action of water is strikingly different: pressed slate can withstand 50 full cycles of freezing and defrosting, and not pressed. Only 25.

If there is an assistant, then try to bring a hose to the cutting site, so that the water spreads along the plane of the slate in the place where you will cut. In this way, you can avoid spraying asbestos dust, which will drip onto the ground in the form of dirt. Its remains must be washed off from tools and surfaces, as the dirt will harden upon drying.
