Modern roofing materials are beautiful and strong, no one will argue.However, the good old slate also do not lie on the shelves.After all, it is very cheap, is not afraid of fire, and other technical characteristics of a good.To use only the wave of the roof slate, large enough to cover the waste with a minimum of almost any roof.The main thing - to evade its slope was no less than 12 degrees.That's about the size of the wave and flat slate and will be discussed in this article.

Species slate sheets andbasic parameters

There are 2 types of slate:

  • Wave;
  • flat.

Wave Slate may consist of:

  • 5 waves;
  • 6 waves;
  • 7-waves;
  • or 8 waves.

flat slate roof is not very suitable.Usually it is used for wall mounting or partition in the outbuildings.

Slate sheets corrugated (consisting of five, six, seven or e

ight waves) are produced in accordance with GOST 30340-95.However, some manufacturers are doing it on their own coverage TU (technical conditions).This is allowed, but in this case the dimensions of the wave plate slate may differ from the standards.

The main dimensional parameters slate sheets include the following:

  • length and width of the sheet;
  • sheet thickness;
  • distance between adjacent crests of waves (wave step);
  • height of the crest of the wave.

grades according to GOST corrugated slate just two:

  • Mark Slate 40/150.Step it waves - 15 centimeters, and the crest of the wave height - 4 cm.
  • Mark Slate 54/200.Step wave - 20 cm, height - 5.4 cm.

Besides the size of waves, slate can also view different profile.Profile is divided into the following types:

# 1. Profile unified, having the abbreviation HC is the most economical material.The waste when it is used the smallest.It is often used as a roofing houses.

Sheet size:

  • width - 1,125 m;
  • length - 1.75 meters.

# 2. Profile ordinary, abbreviated as BO.

has an average size of the sheet:

  • width - 0.68 m;
  • length - 1.12 meters.

# 3. gain profile for short BV, has a greater thickness (8 mm).Therefore, it is mostly used for industrial applications.

Sheet size:

  • width - 1 meter;
  • length - up to 2.8 meters.

Overall characteristics Slate

dimensions of various kinds of slate

Seven and eight waves - optimal, as experience has shown

roof garden or a small house (two floors), a slate acquire more often.After all, Useful area sheets he is not very different from their full area.Because the standard overlap, constituting one or two waves is small compared to the overall dimensions.By the way, for the convenience of overlap wave slate, located on the edge, have a slightly different size than the average wave.Standard allows this.

Both of these general types of slate are the height of the wave crest (4 centimeters) and its step (15 centimeters), and the plate thickness (5.2 or 5.8 mm).These parameters must comply with GOST 30340-95.

remaining dimensions different slate sheet.

Let's start with the size of 7 Slate wave:

  • The total area - 1,715 square meters;
  • useful (real) area - 1,336 square meters;
  • weight - 23 kilograms;
  • length - 1.75 meters;
  • width - 0.98 m;

One sheet of slate with eight waves has the following parameters:

  • Area (full) - 1,978 square meters;
  • actual size (with joint it to 16 centimeters) - 1.57 square meters;
  • weight - 26.1 kilograms;
  • length - 1.75 meters;
  • width - 1.13 m;

five and six waves - are more suitable in the production of these types of

slate often Croutes different premises for industrial purposes, such as warehouses.But in private construction use them unprofitable.The fact that the size of the wave slate 8 is exactly the same as at 5 wave.As a result, taking into account the overlap is too great a difference between the total area and the actual roof.As a result, we obtain a significant cost overruns.

thickness of the roofing material is on the order of 7.5 millimeters.Thicker slate (7.5 mm) much less broken in bending and not so much destroyed by the shocks and loadings.And negative temperature it can withstand two times lower than the thin slate.

At 6 Slate wave size is somewhat different.His standard sheet has the following dimensions:

  • length - 1.75 meters;
  • width - 1,125 m;
  • wave step - 20 cm;

Dimensions slate sheets

Slate flat - popular for cladding and fencing

thickness of the flat sheets of slate can be from 8 to 20 millimeters.In Slate flat sheet sizes can be as follows:

  • Length - 3 meters, width - 1.5 meters;
  • length - 2 meters, width - 1.5 meters;
  • length - 1.75 meters, width - 1.13 meters;
  • length - 1,5 m, width - 1 meter.

However, the popularity of all the sheets with a length of 1.75 meters and a width of 1.13.The most demanded their thickness - 10 mm (sheet weighs 40.1 kilograms), 8 mm (the weight of 30.5 kilograms) and 6 mm (the weight of 21.2 kilograms).

Flat sheets of slate

How to calculate the right amount of slate

We measure the length of the roof, and then divide this number by the width of the sheet of slate.Subtracting one-tenth on the overlap, we know how many sheets we have for one series.And the distance from the base of the ridge to its lower overhang must be divided by the length of the slate plate.There is no longer add 10 and 13 per cent overlap.Rounding - here the number of rows.In any case, always buy a couple of sheets of more than calculated.
