Slate 8 wave. Dimensions of different types of slate. Seven and eight waves are optimal, as experience has shown

For more than 100 years, 8-wave slate has not lost its popularity as a material for roofing. Knowing its size, you can calculate the required amount. Sheets also vary in thickness, weight and other characteristics. This must be taken into account before constructing the roof. The size of the 8-wave will help calculate GOST. When covering the roof yourself, you should familiarize yourself with all the nuances of the process.

general characteristics

Sheets of 8-wave slate of a certain size are used in roofing work. For such conditions, flat varieties of material are not suitable.

8-wave slate, which must be taken into account before purchasing, is made from asbestos cement. This is a fragile but very durable coating. Low cost along with long lasting service life make it popular in the construction business.

In order to correctly calculate the amount of material required for the roof, you need to know the size of the 8-wave slate sheet, its weight and thickness. You should also take into account the number of overlaps and the eaves descent before purchasing. Correct calculations will allow you to purchase the required number of sheets of eight-wave slate corresponding to the size of the roof, without excess or shortage.

Scope of application

The size of the 8-wave slate sheet is important for the construction of 1-2 storey buildings. They are very popular in this area. In addition to houses and cottages, the presented material is used for covering outbuildings, baths, etc. Sometimes it is used to build a fence.

To install a roof on a rafter system with your own hands, you need to know what load the foundation is designed for, bearing structures building. After all, as can be seen from the above parameters, slate is a rather heavy material.

It should only be used if the entire structure is designed to support the appropriate roof weight. Otherwise, you will have to pay attention to a lighter, but more expensive material.

Slate size for roofing

When covering a roof, it is important to know the size of the 8-wave slate sheet. It should be noted that similar material arrange the roof at an angle of at least 12 degrees.

There are practically no restrictions on the use of such sheets. Its dimensions are suitable for any base. The width and length of the sheets allow the material to be mounted on the rafter system as economically as possible. The use of cutting allows you to organize the process with a minimum amount of material waste.

GOST number 30340-95 regulates the production of such a product as 8-wave slate. Sheet size, weight and other characteristics sometimes differ from the parameters established by the standard. This may be due to counterfeiting of sheets or the use of one’s own technical specifications in production.

Sheet Options

If the manufacturing company does not have its own individual technical specifications for the production of slate, the sheets should not differ from the GOST parameters. Otherwise, such products will be regarded as defective building materials.

In the case where the manufacturer has produced 8-wave slate according to the standard, the sheet size will be 175 cm long and 113 cm wide. Thickness asbestos cement material it may be 5; 5.2; 5.8 mm.

The weight of such a product will vary depending on the previous indicator. They can weigh 20, 20.6, and 26 kg respectively.

For correct calculation material, you need to know the expected loads on the roof.

Brand and profile

According to GOST, domestic producers provide the size of an eight-wave slate sheet when manufactured with a certain height and wave pitch. There are two types of profile. The first brand includes slate 40/150, and the second - 54/200. In the first case, the wave height is 40 mm, and the wave pitch is 150 mm. In the second option, these parameters are, respectively, 54 mm and 200 mm.

The profile of the presented products can be ordinary (VO), unified or reinforced (RU). Each of them is used for a specific type of object. When using a unified profile (117.5x112.5 cm), the least amount of waste remains. Brand VO (112x68 cm) is used in private construction, and VU (280x100 cm) is used for industrial facilities.

Material calculation

The size of the 8-wave slate sheet will allow you to correctly calculate the required amount of material. It should be noted that the overlap width may vary. It comes in 1 or 2 waves.

To calculate the material, the length of the roof is first measured. The result is divided by the width of the sheet and 10% is added for overlap. This gives the developer the opportunity to calculate the amount of material for 1 row.

Then the distance from the base of the ridge to the bottom overhang is measured. The result is divided by the length. The margin should be considered about 13%. This allows you to get the number of rows. Next, it will be easy to calculate the required amount of material.

When purchasing, you should take several sheets more than the obtained value. The material is quite fragile, so if it breaks, you won’t need to go to the store again.

Once you know the size of the 8-wave slate sheet, you can correctly calculate the required amount of material. It has a small difference between the nominal and usable area. The characteristics of this type of slate make it popular among builders. Low waste levels, durability and relatively low cost keep roofing at the peak of popularity.

Advantages of wave slate

Roofing profiled slate has the following advantages:

1. Resistant to sudden temperature changes and prolonged negative mercury levels. It is successfully used in the northern regions.
2. No fear high humidity air and precipitation (snow, rain).
3. Does not fade or deteriorate under direct influence sun rays, not afraid of ultraviolet radiation.
4. Ease of installation work. Slate is easy to install thanks to the wave connection.
5. Versatility of sizes. Profiled sheets have standard size and 98% of usable area, which allows installation with their help roofing structures of any complexity.
6. Strength, reliability and durability. Properly installed slate will last at least 70 years!
7. Profitable price profile products 5-10% cheaper than the cost of other roofing building materials.

Areas of application of wave slate

Wave multi-colored sheets received wide application in civil, industrial and technical construction. This type of slate is used to cover roofs, and wave products are used to lay out technical premises. Various fencing structures are mounted with slate and other uses are found for profiled slate.

Order and purchase wholesale quantities of wave roofing products from the manufacturer with delivery to favorable conditions at a convenient time on the company’s website or by contact phone numbers.

Modern roofing materials are beautiful and durable, no one will argue. However, good old slate also does not sit on store shelves. After all, it is very cheap, it is not afraid of fire, and others specifications has good ones.

For roofing, only corrugated slate is used, the sheet dimensions of which allow covering almost any roof with a minimum of waste. The main thing is that the slope of its slope is at least 12 degrees. Specifically about sizes 5, 6, 7, 8 wave slate and we'll talk in this article.

Slate sheet sizes 6, 7, 8 wave.

There are four main types of asbestos-cement roofing sheets:

1. Flat;
2. 6-wave;
3. 7-wave;
4. 8-wave.

Flat products are used in the construction of partitions and roofs, while wave products are used exclusively roofing material. Their production technology and composition are the same; they differ only in their cross-sectional profile.

GOST size flat slate in millimeters - these are slabs 2500x1200, 3000x1200, 3000x1500, 3600x1200 and 3600x1500. Their typical thickness is 6, 8 and 10 mm. The weight of such asbestos cement sheet ranges from 38 to 115 kg.

Table of sizes of 6, 7, 8 mm slate and its price:

When calculating the amount of material in question required for a roof, you should focus not on its general dimensions in the markings, but on the working ones. Each sheet of wave sheet is superimposed on the previous one with an overlapping offset. Therefore, cutting and displacement will require about 15–20% of the area of ​​the roof to be covered.

Slate 5 wave sizes 1 sheet.

5-wavy slate or Europrofile appeared on the market relatively recently; its production was launched only in Ukraine in the city of Balakleya.

With parameters identical to 8-wave slate, Europrofile has a unique sheet geometry. Instead of standard waves, this model features flat depressions, which improves performance characteristics.

The parameters of 5 wave slate are as follows:

• length: 1750.0 (mm);
• width: 1130.0 (mm);
• thickness: 5.8 (mm);
• regulated by: GOST 30340-2012.

The number of waves in slate and its practicality.

Wavy slate is produced in accordance with GOST 30340-95. According to this document, asbestos-cement corrugated sheets must have 6, 7 or 8 waves.

Sheets with 7 and 8 waves are the most practical. This is due to the small difference between their nominal and usable area. 8 wave slate has a total area (nominal) of 1.978 m2, and a useful area of ​​1.57 m2. That is, when installing such slate over overlaps (1-2 waves on both sides), a small part of the material is lost. The same can be said about 7 wave slate. Its nominal area is 1.715 m2, and its useful area is 1.3362.

The consumption of 6-wave slate when installing the roof will be slightly higher. The total area of ​​a standard sheet with 6 waves is 1.97 m2. Wherein effective area– 1.41 m2. Thus, the overlaps take up about 20% of the total material.

In addition to slate with 6, 7 and 8 waves, some factories produce material with 5 waves. However, it should be understood that such material is produced not according to GOST standards, but according to individual plant specifications.

Detailed dimensional characteristics of corrugated slate brands - table.

How to calculate the required amount of slate.

We measure the length of the roof, and then divide this number by the width of the slate sheet. By subtracting one tenth for the overlap, we find out how many sheets we need for one row. And the distance from the base of the roof ridge to its lower overhang must be divided by the length of the slate sheet. Here we will add not 10, but 13 percent for the overlap. Let's round - that's the number of rows. Just in case, always buy a couple more sheets than you calculated, as there is a chance that several sheets will crack during installation.

8-wave asbestos-cement slate is a popular roofing material. This is a durable and wear-resistant coating. Lasts a long time and reliably. Currently, colored sheets of various colors are produced. This adds variety to the architectural appearance of buildings with such roofs.

Asbestos cement is considered not a completely environmentally friendly product. It is recommended to be used for external construction work. But even so, the scope of its use is quite wide.

What is 8-wave slate? Pros and cons of coverage

Wave slate- This is a sheet of asbestos cement, has a wavy profile. It differs in the number of waves located along the width of the sheet. In this case, we are interested in a sheet with eight waves.

The composition and characteristics must meet the requirements of standards or specifications, otherwise it will be a defective product, deprived of its basic qualities. During manufacturing, certain dimensions of the wave must be maintained - its height and pitch.

The type of slate profile is regulated. One of them has a wave height of 40 mm, its pitch is 150 mm, designated 40/150. The sizes of the second type are 54 and 200, designated 54/200.

They also distinguish between the ordinary type - VO and the enhanced one - VU. The type determines the scope of application of the material. Common view used in private and low-rise construction. A unified type is used for roofing industrial facilities.

What are the advantages of 8-wave slate:

• Frost-resistant, easily tolerates temperature changes.
• It is not afraid of high humidity; rain and snow do not leave a mark on the coating.
• It tolerates sunlight well and its long-term exposure.
• Installation of the roof is simple; you can do it yourself if you have certain skills and ingenuity.

Like any item, slate has disadvantages, namely:

• The sheets are quite heavy, which makes it difficult to climb onto the roof.
• Fragile, requires care during transportation and installation.
• Asbestos cement, from which slate is made, has negative impact per person.
• When cutting sheets, it is necessary to use respiratory protection.

Slate production and its composition

The main component of slate is a natural mineral - asbestos. When added to the composition cement mortar, asbestos fibers join together. It turns out very hard material– asbestos cement. Its properties do not change when exposed to moisture, high and low temperatures, various physical activities.

Chrysotile asbestos is usually used. The mineral is fluffed up, Portland cement and water and various additives are added to it. The working composition is pulp; when preparing it, you must strictly follow the recipe in order to obtain good quality.

Exist various settings for slate production. At the first stage, the pulp is kneaded. For this purpose, bucket mixers are used. After thorough mixing, the mixture is removed, the liquid is allowed to drain and sent to a sheet molding machine.

This is where the material is pressed. The duration of the process depends on the type of equipment and pressure. Typically, slate is pressed from 30 to 90 seconds. The continuous strip moves along a special conveyor; a special drum forms strips of a certain thickness.

Rotary shears cut strips into sheets required length. Next, the drums begin to work, forming a wave of slate. Their shape and size determine geometric characteristics finished sheets. The finished sheets move along a conveyor and go through the primary curing stage.

The next stage is water saturation of the workpieces. They are kept in a special pool for a certain time and then sent for drying. This happens in a warehouse with constant high temperature. This is where the material gains its final strength.

Currently, the production of colored slate is common. This increases the wear resistance of the material, gives it new qualities, beautiful view slate roofs. For this, phosphate and acrylic dyes are used.

Use in construction

Its main use is roofing. Roofs in individual and low-rise housing construction. Longitudinal ridges serve as stiffening ribs and increase bearing capacity such coverage. This is facilitated by a thick sheet of at least 5 mm.

8-wave slate has convenient sheet sizes, which makes it easier to install. It should not be used for complex structures roofs, which generates a lot of waste and economic expediency application will be low. It is also not suitable for roofs with a slope of less than 12 0. Water will not drain well from such a coating and its humidity will increase.

Slate is often used for fencing. Low fences made of wavy slate are especially good on personal plots. Painted in various colors they bring a special flavor to the architecture of the garden. Another possibility of using slate is the enclosing structures of outbuildings.

Dimensions and weight of 8-wave slate sheets. Specifications

Table 1 shows the dimensions of 8-wave slate in accordance with GOST 30340-95. The overlapped wave has a height of 32 mm, the overlapped wave has a height of 43 mm. Markings include letters and digital values. They indicate the brand of sheet, number of waves, thickness.

Table 1. Technical characteristics of slate.

Thanks to the material from which it is made, slate has the following properties:

• Capable of withstanding loads of up to 200 kg, which allows you to walk on the roof with installation work and endure snow pressure.
• The density of the material ensures the durability of the coating.
• Water resistance reaches 24 hours; the use of special treatment compounds extends this value.
• Frost resistance.

Installation of slate sheets on the roof. Laying and fastening methods

good durable roof it turns out if the base under it is made correctly. Used as a base rafter system. The sections of rafters and racks must correspond to the expected loads.

Eight-wave slate is laid staggered. The sheets in adjacent rows are shifted, and the longitudinal joints do not match, making it impossible to connect 4 elements in one unit. To ensure this shift, separate sheets cut in half lengthwise. They are used as the first extreme ones for odd rows. Due to this, the displacement occurs.

The sheets are joined with an overlap, trying to ensure that it is located on the leeward side. In the horizontal direction, the stripes overlap by the magnitude of the wave. In the vertical direction, the overlap of sheets is required to be at least 200 mm.

The slate strips are attached to the sheathing using special slate nails or screws. They should have an enlarged cap. A rubber gasket is placed under it. Holes for fasteners should be drilled with a drill, and not punched with nails, so as not to damage the sheets. They are fastened to the crest of the wave, in places where they rest on the sheathing, retreating 120 mm from the edge of the sheet.

Fastening sheets of 8-wave slate in the transverse direction is carried out in the 2nd and 6th waves. IN longitudinal direction the sheet rests on the sheathing in three places, which means the sheet must be fastened at 6 points. It is better to drill holes for fastening slate in advance according to pre-applied markings. The diameter of the hole should be 3 mm larger than the diameter of the fastener.

Asbestos cement slate for a long time was the most popular roofing covering. Since appearing on construction market its consumption of new materials has decreased. It is currently being improved. Two-way protective covering on an asbestos base made the slate environmentally friendly. The production of colored sheets has expanded its scope of use. Undoubtedly, this material remains the cheapest roofing covering in accordance with its performance characteristics.
