Metal roofing difference. Types of metal tiles. Types of protective coatings for metal tiles

Metal roofing today can be seen on in large numbers roofs, both private houses and apartment buildings. The material is attractive appearance, durable and has many other advantages. But not everyone knows that metal tiles are available in a large assortment. And it differs not only in color. And what types of metal roof tiles can be found on the building materials market? On what basis do they differ from each other? This will be discussed in the article.

Why metal tile

Today, for roofing, you can use the most a variety of materials. But most popular in recent times metal tile is used. And why is this roofing material so in demand? The answer is quite simple, the metal tile has many positive qualities, namely:

1. Attractive appearance. The metal tile is issued in big assortment of flowers. But even this is not the main thing. There are many profile forms and. Most often, it resembles natural ceramic tiles, but there are other configurations.
2. The metal tile weighs little. With almost the same appearance as ceramic tiles, the metal version has less load on the truss system. And this means that when building a roof, you can save a little on materials.
3. The cost is another plus of metal tiles. Of course, a lot depends on production. Most often, a steel sheet is used, but if aluminum or copper is used, the price will rise significantly. The cost also depends on coverage. Types of metal tiles are different. If polyester is used, then the price is finished product will be available. Other polymer coating options can cost many times more.
4. High strength. This characteristic is highly dependent on the shape of the profile. It is this convex "pattern" that allows you to strengthen the steel sheet. Also, the strength depends on the thickness of the metal sheet used.
5. Long service life. This factor largely depends on the polymer coating used. It is this layer that protects the metal from corrosion and other harmful effects on the material. But even the most cheap option last at least twenty years.
6. Ease of installation. It is possible to lay a metal tile on a roof without even having special skills. Of course, a lot depends on the shape of the roof. The more complex it is, the more difficult it is to do everything neatly and beautifully. Therefore, for such work it is better to call a team of professionals. In addition, metal tiles can be laid on some types of old coatings (for example, soft roof and roll material).

Of course, do not forget about safety. First of all, it is that all types of metal tiles are not afraid of fire. The protective polymer layer may be damaged from high temperatures, but a fire will not occur. In addition, the metal tile is environmentally friendly. Harm to environment will not occur.

But there are also some minor drawbacks. First of all, it is a quick failure if the protective coating is damaged. Also, some of the disadvantages include the noise of the material. If it is raining outside, then inside you can hear the drops “drumming” on the roof. But here it all depends on the sound insulation, or rather on the quality of its installation.


Production material

Metal tile for roofing is used relatively recently. Some ten or twenty years ago, they mainly used slate or galvanized iron. But these roofing materials have many disadvantages. The main ones are a short service life and an unattractive appearance. The metal tile is devoid of these disadvantages.

But do not think that this roofing option is easy to choose. Going into hardware store, you will see a huge . And the views will differ not only in their color scheme, but also in many other parameters. The most important of these is the raw material from which this roofing coating is made.

There are the following types of metal roof tiles, depending on the material used in the production:




These three types of metal tiles are used in different ways. The most popular is the steel version. And it's mostly about cost. Covering a roof made of steel metal tiles is inexpensive, while the service life is not much different from other types of material.

Profile

Types of metal tile coatings may differ in their profile. This is due to the way this type of roofing material is produced. The original sheet of metal, mainly steel, after being coated with a protective layer of zinc, is placed in a rolling machine. Here, under the influence of the rollers, protrusions are obtained, which are called profiles.

To a greater extent, such a convex "pattern" improves the appearance. But this is not the only purpose of the profile. Such "bulges" help to improve the strength of the metal tile. In the production of such a roof covering, a thin sheet of metal, less than a millimeter in thickness, is used. If you do not use profiles, then the metal tile may not withstand all the loads.

According to this characteristic, roofing material can be divided into the following varieties:




Types of profiles of metal tiles are quite diverse. Each owner of a private house can easily pick up suitable option. But when making a choice, in addition to the appearance, it is worth looking at the height of the profile. The ease of installation and the strength of the metal tile depend on this.

polymer coating

External forms of metal tiles can be different. Here the owner of a private house, when buying, will listen more to his taste and preferences. But it is worth remembering one thing, all types of metal tiles (at least those made of steel sheets) have a special polymer coating. It is this layer that performs protective function. Of course, the coating of the metal tile helps to improve its appearance. It is the polymers that give the roofing material its color. But the main role of such a layer is precisely protective.

What types of metal roofing are available? Answering this question, experts will name the following approximate list:

1. The metal tile can be protected with a layer of polyester. Such a coating can be glossy or matte. The first option is considered budget. The layer is applied from pure polyester with a thickness of not more than 30 microns. The disadvantage of this option for protecting metal tiles is the ease of damage, especially during installation work on the roof. Matte polyester is made with the addition of Teflon and with a layer thickness of 35 microns. Such a coating is more durable, but at the same time not much more expensive than a glossy look.
   
2. Metal tile with a protective layer of plastisol. Such a coating is considered the thickest, up to 200 microns. Plastisol is polyvinyl chloride. Such protection is durable and easily withstands mechanical stress. But there is one significant downside. The metal tile of this type does not tolerate ultraviolet exposure, it quickly fades. Therefore, it is better to choose light colors, especially for a region with large quantity sunny days per year.
   
3. A mixture of acrylic and polyvinyl fluoride is also used to cover metal tiles. Such protective layer very reliable, but also expensive. This type of roofing material is most often used for roofing at industrial facilities.
   
4. Metal tile with a pular layer is considered the most expensive. But this price is due to many positive characteristics. Such a metal tile easily tolerates both frosts and exhausting heat. In addition, the material can be mounted even using seam joints. Another plus is the inability to damage the surface. mechanical action. Thanks to all these pluses, the type of metal tile with a pular coating is considered the most durable. Having paid once, you will forget about roof repairs for a long time.
   

As you can see, metal tile coatings can be very diverse. The choice is both in terms of durability and cost. The most popular is polyester. Both the glossy and matte version of the metal tile serves for a long time, while it is inexpensive. But here it is important not to damage the protective layer. That's why installation work must be done with all caution.

What are the types and forms of metal tiles.

Today, in terms of its diversity, there is already a huge number of different types metal tiles, differing not only color solutions, but also wave profiling forms in the metal tile pattern, step depth, module size, type of coating, etc.

Over the past 10 years, the metal tile market has changed a lot. If earlier there were no more than two dozen manufacturers and metal tiles were distinguished mainly by the thickness of the metal and the country of the manufacturer, today almost every town has organizations involved in the production of metal tiles and corrugated board.

People directly specializing in metal tiles consider the main and main criterion metal thickness used in the production of metal tiles. For them, the standard of quality has become a metal tile with a thickness of 0.5 mm, and they perceive deviations of even 1 micrometer (0.01 mm) negatively. It should be noted that the thickness of the metal metal tile is from 0.4 mm to 0.5 mm.

Variety of colors of metal tiles can be according to RAL color standard or RR color standard.

new trend- structured colors of metal tiles with imitation of wood, stone, brick, ceramics and whatever you want.

Types of profiling - drawings of metal tiles

As for the pattern (form of profiling) of the metal tile, there are types, the names of which are different for different manufacturers, but indicate the same profile. Below, we tried to combine the nomenclature of profiling from different manufacturers in accordance with the profile pattern of the metal tile:

Profile "Monterey", "Classic", "Standard"

This pattern of metal tiles appeared in the domestic construction of roofs the very first, in the early 90s. Therefore, at present, many domestic producers metal tiles and suppliers often label it as "Standard" or "Classic". This is the most common type of MCH profile. Monterey's pattern is a balanced wave profile, reminiscent of classic tiles.

Profile "Modern"

Metal tile "Modern". For some reason, it is believed by many that this is one of the varieties of the Monterey profile. But unlike Monterey, the profile "Modern" has angular edges instead of semicircular shapes. Also, the sole on the "modern" profile has an even flat shape.

A flat sole and corner bends of the wave are what distinguishes the metal tile of the "modern" profile.

Profile "Cascade"

Metal tile "Cascade" is one of the most prominent patterns of metal tiles. Outwardly, the Cascade profile resembles a chocolate bar. The straightness of the forms of this profiling make it easy to install not only simple, but also more complex roofs. Roofs with a roof made of such metal tiles externally have a strict geometry, clear rectilinear shapes and a classic proportional look.

There are several types of "Cascade" metal tiles, which differ only in the geometry of the profile (differences in wave height and installation width).

The "Cascade" profile looks perfect on the roofs of houses with gables, but is less well suited for hip and hipped roofs.

Profile "Joker"

Metal tile " Joker"This is a profile that has a classic geometry. The pattern of the metal tile "Joker" is a regular wave with rounded contours of both the wave crest and the bottom.

Profile "Andalusia" and "Venice"

Metal tile " Andalusia"is a new direction in the profiling of metal tiles. It differs from all other types of metal tiles in a hidden fastening.

Metal tile " Venice"has a beautiful large pattern that imitates natural tiles, which gives a kind of originality to the roof.

Profile "Adamant" and "Valencia"

New possibilities in profiling metal tiles. beautiful drawing roofing" Adamant" gives hope for good prospects for this profile in the future. Adamant quickly became popular not only on advertising stands, but also on the roofs of cottage houses.

Profile "Kron"

Metal tile " Cron"has a flat sole and a low narrow wave. It is most convenient for installation and movement of the installer on the surface of the metal tile.

Profile "Opal" and "Athena"

Metal tile " Opal"similar to the above profile" crowns". It also has a flat sole, but unlike the "crown" in the "Opal" profile, the width of the sole is equal to the width of the wave.

"Banga" profile

Another type of profile with a flat sole is a metal tile " Banga". It the new kind profile, which appeared relatively recently. " Banga"has the highest wave of all metal tiles. Unusually bizarre geometry from the high profile of the wave gives a three-dimensional visual effect, obtained due to the significant convexity of the forms. Banga suitable for large buildings with high roofs. On small forms it does not give a good visual effect.

Profile "Shanghai"

Rumor has it that this profile of metal tiles came to us from China. Hence the name " Shanghai". This metal tile has an asymmetrical appearance.

Metal tile is a popular roofing material. It is functional and practical. The main advantages of such a coating are: ease of installation, ease of construction, design attractiveness and economic benefits. The article discusses in detail all types of metal tiles, presents an analysis and comparison of types, gives advice on choosing this roofing.

General information

The metal tile, due to its general positive qualities, quickly took a leading position in construction market. This universal coating can be used not only for arranging the roofs of individual cottages, it is used for any buildings in the private sector, or for covering small public buildings: offices, cafes, remote platforms, shops.

A metal tile is a roofing material that consists of metal with a certain profile and a protective coating of various polymeric materials.

By their own functional features metal tile is divided depending on:

1. Production material - bases
2. Sheet coatings
3. Profile shapes and heights

The composition of sheets of metal

Aluminum or steel sheet can be taken as the basis of a sheet of metal. The bulk of production falls on products made of steel sheets. The standard thickness of a metal tile is 0.5 mm, but samples with a thickness of 0.55 - 0.6 mm are also available.

In the second case, steel sheets are coated with zinc or aluzinc (an alloy of aluminum, silicon and zinc). This increases the resistance of the roofing to adverse effects. Additionally, the sheets are covered with a protective shell of basalt chips. For example, the Gerard metal tile is made of steel sheets with aluzinc and protected by a layer of natural stone chips.

Aluminum-based sheets are light, practical and durable (does not corrode), but are more expensive than steel sheets. Such a coating is presented on the market, for example, by the manufacturer Plannja (Sweden). Such a metal tile is not particularly popular among consumers due to the high cost and limitations in color scheme.

Copper metal tile

A beautiful metal tile made of stamped copper sheet is produced by the Belgian company Metrotile. It's very practical roofing antique. Some ancient buildings and architectural forms are covered with such sheets. Copper has no coating - over time (after 12 years) the roof on the building is covered with a green patina, this is what gives the building a noble antique look.

Coating of steel sheets

The practicality and durability of a metal tile roof depends not only on the base material, but also important element is its protective coating. The main steel sheet is “packed” in several layers that reliably protect it from external influences and destruction.

Sheets can be coated with:

• Polyester matte or glossy
• Plastisol
• PVDF (polyvinyl fluoride)
• Terra Plegel.

The main features and differences of each of the coatings

Polyester is a fairly cheap coating sprayed onto the front surface. steel sheet tiles. There are two subspecies of polyester coating - glossy and matte.

Glossy (standard) polyester is a thin coating of about 25 microns. A metal tile with such a coating is cheaper, it is presented on the construction market with the largest color range. A distinctive feature of this coating is the possibility of re-staining, which is not available with all other coatings. The disadvantages include hypersensitivity to mechanical damage and color fading.

Glossy polyester finish

Matte polyester is thicker - 35 microns. This coating has no shine, which is why it realistically imitates real ceramic tiles. Such a metal tile is more resistant to corrosion and damage, the color retains its freshness for a long time. The material costs an average of 10% more than glossy.

Plastisol in terms of price range is akin to a polyester coating. It is created by rolling a plastic film onto a steel sheet. The difference in layer thickness is 200-250 microns. Such a metal tile is especially popular in areas with a humid climate, as the plastisol coating reliably protects the metal from corrosion. The coating is resistant to mechanical damage and action low temperatures. The downside is a little resistance to high temperatures and too active sun.

Plastisol coating

Pural is a polyurethane-based coating with the addition of polyamide. Layer thickness - 50 microns. Such protection is the most resistant to corrosion, perfectly withstands damage. hallmark is increased resistance to ultraviolet radiation and adverse weather conditions. The price of a metal tile with a pural is on average 35% more expensive than a material with a smooth polyester coating. A minor disadvantage is the small color gamut. This coating is used by manufacturers Ruukki, Pruszynski.

It should be noted that the pural coating and matte polyester are used much less often than protection from plastisol and standard polyester. Coatings from PVDF (polyvinyl fluoride) and Terra Plegel are also not very common due to the high cost and application features.

The PVDF coating is very thin, but is the most stable and expensive, produced by the Finnish company Ruukki. Such protection does not delaminate, withstands high temperatures, available in a wide range of colors. The color of metal tile sheets in any operating conditions does not lose its brightness for a very long time.

Terra Plegel coating is able to give the steel sheets of metal tiles a natural look of a classic clay coating. Terra Plegel is made by applying to melted plastisol quartz sand. In addition, a paint layer is applied to the coating.

Terra Plegel Coating – kofe

Attention! The main average load of metal tiles per 1 m 2 is within 5 kg. Load capacity of sheets coated with Terra Plegel - 8 kg.

Metal tile: sheet dimensions and profile depth (height)

The stamping depth of a steel sheet affects its rigidity. The more often and more the relief protrudes, the less flexible the metal tile sheet will be. Basically, the depth of the metal tile stamp is set by the manufacturer and varies depending on the model. For example, Ruukki offers Decorrey with a minimum profile height of 28 mm and Finnera with 52 mm. The most common profile height is 40-45 mm, the maximum is 78 mm. The height of the profile is an important indicator when replacing old sheets, or laying metal tiles in certain places roofs where flat profile sheets are needed.

Manufacturers produce metal tiles with a profile thickness of 1100-1200 mm and a sheet length from 0.8 m to 8 m. Firms provide a service for cutting sheets to the required dimensions.

Types of metal roof tiles. Profile form

According to the shape of the profile, the metal tile is symmetrical and asymmetric with a beveled wave. The symmetrical shape is less common than the asymmetric one. Price range and practical qualities they are no different.

The metal tile according to the type of wave is divided into several models:

• Monterrey
• Modern
• Andalusia
• Cascade
• Joker
• Banga
• Shanghai

Monterrey

Monterrey metal tile is the most popular type of roofing. The shape of this profile most fully repeats the classic look ceramic tiles. Such light coverage, well protects the roof from environmental influences, practical and durable.

Modern

This roofing is a type of Monterrey metal tile. The main difference is in the angular waveforms, instead of rounded, flattened shapes. Visually, these forms differ quite strongly.

Andalusia

Such a profile has not yet received mass distribution in the modern domestic market. Special equipment from Western manufacturers allows the production of Andalusia metal tile sheets with built-in hidden fastening.

Cascade

The second most popular type of metal tile profile. Its shape looks like a chocolate bar. This rectilinear roofing has a large installation width, which distinguishes it as the most economical roofing. The Cascade metal tile is convenient for the installation of complex roof structures. Such buildings have strict proportional geometric shapes. There are several varieties of the Cascade profile, which differ in wave height and sheet width.

Joker

This type of metal tile is made in a classic style. A smooth wave with rounded contours looks beautiful and really resembles waves.

Banga

Completely new, elite look profile. A bizarre and unusual geometry of forms gives a unique look to the roofing. Banga is distinguished by a high profile wave, but a small installation width. because of unusual shape a beautiful visual effect of the bulge and grandiosity of the roof is created. Therefore, such a metal tile is very well suited for tall large cottages and buildings, where the beauty of the profile shape can be fully revealed.

Shanghai

This is a symmetrical profile in oriental style, which got its name from the country from which it "came". Sheets of Shanghai metal tiles have a low wave, in the hollow there is an additional decoration with stripes.

How to choose a metal tile

The fundamental parameters when choosing a roofing are the shape of the sheet, the type of polymer coating and the thickness of the material. The parameters of the roof frame are also important ( truss system), mounted under a metal tile.

The color of the metal tile can be any, but it is desirable that it matches the general design idea the entire area on which the house is located.

The type of polymer coating is selected depending on the intensity of the adverse effects of the environment. If there is no strong scorching sun in the area of ​​\u200b\u200bresidence, and the winter is mild, then a regular polyester coating is chosen, which will save on costs, but the material will last a long time without damage.

When buying a metal tile, you should ask in detail about all the parameters and see the quality certificate. The guarantee for such roofing material is on average 10 years. It is given on a polymer coating. The actual service life of a properly selected metal tile reaches 50 years, subject to all requirements for installation and operation.

Outwardly similar to natural tiles, but lighter and cheaper, metal tiles have become one of the most popular roofing materials. It is used for arranging the roofs of private and multi-storey buildings, industrial buildings and shopping facilities. The high demand is explained unique operational qualities , excellent appearance, a wide variety of textures and colors. When choosing a metal tile for a roof, you need to consider many factors: from the thickness of the sheet and the type of protective coating to the shade and shape of the profile. Not the last role is also played by the name of the manufacturer.

No. 1. Features of the production of metal tiles

The main for the manufacture of metal tiles can serve one of the following materials:

• steel sheet;
• aluminum sheet;
• copper sheet.

The most commonly used galvanized steel, which, thanks to stamping, is given a certain profile that imitates. On top of the zinc protective layer can be used phosphate layer which improves corrosion resistance. The next layer is primer, which improves adhesion to the polymer-decorative coating. Backside also passes galvanization and is in addition protected by a layer of a transparent varnish which prevents emergence of small scratches. The strength of the material depends on the thickness of the steel sheet, and the period of preservation of the original appearance and resistance to negative environmental factors depends on the type of polymer coating.

aluminum sheet can do without an anti-corrosion coating, but an additional protective polymer layer is still used, because it allows you to increase the strength and durability of the material. Aluminum tiles are light, which simplifies transportation and installation, but they do not have many color options, and they are more expensive than steel counterparts.

Copper sheet metal tile it is very expensive, rarely used, but it looks excellent, and the appearance only improves over time, because a greenish patina appears. It also protects the material from negative factors, so no additional protective materials are used. You can see such tiles on some old houses.

Since the most widespread metal tile is made of galvanized steel, then this material will be discussed further.

No. 2. Advantages and disadvantages of metal tiles

The metal tile is catching up in popularity. She was brought to the leaders of the market of roofing materials numerous benefits, among which:

There are metal tiles and some limitations:

The existing shortcomings are not able to cross out the numerous advantages of metal tiles, which are used today for arranging buildings for various purposes.

Number 3. Steel sheet thickness

When choosing a metal tile, first of all, attention should be paid to the thickness of the steel sheet. From this setting depends on the strength of the material and ease of transportation. Standard thickness - 0.5 mm. Such a metal tile can be used for roofing of residential, public and industrial buildings. Some manufacturers today offer material with a thickness of 0.55 mm - it is even more durable and rigid, it is used where there are increased requirements for the roof.

On sale today it is easy to find metal tiles with sheet thickness 0.45 mm. Such material is much easier to deform, therefore, it can only be used for arranging outbuildings, sheds and other similar objects. Sheets 0.4 mm thick poorly suited even for these purposes, they are difficult to transport and assemble, since thin material is easily deformed.

It is possible to distinguish sheets with a thickness of 0.4 mm from similar ones with a thickness of 0.5 mm even by weight - the first ones are 25% lighter. More accurate results will give micrometer check, which is better to arm yourself before buying a metal tile, so as not to fall for the tricks of unscrupulous sellers.

No. 4. Quality of galvanization

No. 7. Profile type of metal tile

Along with a shade, the type of profile also affects the perception of a metal tile. Height, pitch and waveform can be different. Manufacturers produce metal tiles with such main types of profiles:

• Monterrey. Such a metal tile strongly resembles natural clay, has a smoothly rounded profile, and has gained the highest popularity;
• Andalusia. The profile has a wave shape, its main feature- the ability to fasten in a hidden way due to the presence of special locks;
• Shanghai. It is distinguished by a high profile, the presence of waves and several grooves, it looks interesting and unusual, it has been used in the domestic space quite recently.

No. 8. Manufacturers of metal tiles

The popularity of metal tiles has led to the emergence of huge amount dishonest manufacturers. To reduce the cost of production, they use not the highest quality raw materials and equipment that has worked out its resource, and the accuracy of sheet dimensions depends on the reliability of the latter. Responsible domestic manufacturers use modern imported equipment, so the quality of their products is not much inferior to foreign counterparts. The difference in the price of metal tiles from a well-known reputable manufacturer and a little-known dubious company can be only 10-15% - the savings are not worth the risk, especially since large companies give a guarantee on their products.

When buying, you should specify the duration warranty period and see the certificate of quality. Some big companies put a marking on the metal tile indicating the date of production, the name of the manufacturer and information about the origin of the raw materials.

In the domestic market, the products of such manufacturers.
