Among all roofing materials, metal tiles rank high in popularity. And this is not without reason. Sufficient strength, resistance to weather conditions, a wide choice of colors, ease of installation, light weight and significant service life - all this makes metal tiles very attractive when choosing a material for roofing in individual construction.
Metal tiles will be an excellent choice for roofing cottages, bathhouses and any other structures on a country site.
Let's look at the main types of metal tiles, find out their characteristics and physical properties, as well as the materials from which it is made.
Metal tiles are a modern roofing material, consisting of a metal base of a certain profile with layers of protective coatings made of polymer materials applied to it.
The metal base most often used is galvanized iron, sheet aluminum, and copper.
In appearance, metal tiles resemble traditional clay tiles, which gives the structure a neat appearance. appearance, which is significantly more attractive than roofing felt or slate roofing.
Due to its structure, metal tiles have a very long service life, reaching up to 50 years without replacement. It should be remembered that its service life largely depends on the degree of exposure environment and type of protective polymer coatings.
With a sheathing pitch of 30-50 cm, tiles with a thickness of 0.45-0.5 mm can withstand the weight of a person and a significant snow load (up to 250 kg/sq.m).
As mentioned above, the basis of metal tiles is a metal sheet. Today, several main types of metal tiles are produced - these are metal tiles based on galvanized iron with a thickness of 0.4-05 mm, aluminum or non-ferrous alloys.
Metal tiles based on galvanized iron are most often used in construction due to their lower cost. Products based on aluminum, copper or non-ferrous metal alloys, although they last much longer, have a significantly higher price.
To increase durability, the base metal sheets are coated with special protective coatings.
Most budget option is a coating of standard polyester 25 microns thick. Despite low price and a large selection of colors, this coating is the least resistant to fading and various damages. But its low cost makes it a fairly popular choice.
Thicker coating is made from matte polyester. Metal tiles with such a protective coating are most similar to ordinary ceramic tiles. Its service life is longer due to the greater thickness of the coating (35 microns).
Pural- This is a type of coating based on polyurethane. His distinctive feature is a very high resistance to solar radiation, allowing for many years to maintain the original color and effectively resist fading. The thickness of a covering made of pural is twice the thickness of a covering made of standard polyester, but metal tiles with such a coating are also more expensive.
PVDF– modern coating based on polyvinyl fluoride. Despite its small thickness, today it is one of the most resistant coatings. Metal tiles coated with polyvinyl fluoride will last a very long time, but will not be cheap.
There is another type of coating - this plastisol, having a large thickness (200-250 microns) and excellent resistance to mechanical damage.

All types of metal tiles differ not only in the base material and protective coating, but also in the shape and height of the profile. Its rigidity directly depends on the profile, which is important when installing a roof in areas with high snow cover. The higher the profile, the stronger the roof will be.
The most common profile is 40-45 mm high. The most common profile shape is S-profile. The popular types “Andalusia” and “Monterrey” have this shape.
Also quite popular are such profiles as Modern, Cascade, Joker, Banga, Shanghai. They all differ from each other in height and pitch, on which the appearance of the roof depends.
What each of these types of metal tiles looks like is shown in the figures below:
Metal tiles are produced in widths of 1100-1200 mm (depending on the manufacturer). The length of the sheet can be from 800 mm to 8 m, depending on the requirements of the customer. Today, many manufacturing plants offer cutting sheets according to the required sizes.
The thickness of the metal tile sheet is from 0.45 to 0.5 mm. Weight, depending on the base material and type of protective coating, ranges from 4 to 7 kg per square meter.
When choosing a metal tile, you should pay attention to its appearance, the thickness of the metal and the type of polymer coating.
The color of metal tiles should be selected in accordance with the general color scheme building site and neighboring buildings. Most often, colors close to the color of ceramic tiles are chosen, dark brown; colors of greenish shades to match the surrounding greenery of the trees are also in demand. Otherwise, the roof will literally be an eyesore, standing out too much from the surrounding color scheme.
If you live in an area where there is a lot of snow in winter, then for greater roof strength you should choose metal tiles made from a metal sheet with a thickness of at least 0.5 mm.
Depending on intensity atmospheric influences you should choose the type of polymer coating. If your site is located in middle lane, where there is no scorching heat of the sun in summer, and winter is not characterized by bitter frosts, then you can choose standard polyester, which will allow you to significantly save on the purchase of metal tiles.
If you live in an area with significant temperature changes, or sea coast where the air is saturated with vapors sea water containing substances that are aggressive to building materials, then a higher degree of protection is needed. In this case, it is worth taking a closer look at metal tiles coated with plastoisol, pural or polyvinyl fluoride.
When purchasing metal tiles, do not hesitate to ask for a quality certificate. This will help protect you from purchasing products from unknown companies of dubious quality.
Now you know enough to navigate the store building materials when purchasing metal tiles.
In the next publication we will learn about corrugated sheets (corrugated sheets) - we will consider the types of corrugated sheets, find out its main characteristics, understand what its marking means and get acquainted with the most popular brands of wall and roofing sheets, produced by industry.
Metal tiles are in great demand because they are light in weight, easy to install, very attractive in appearance, quite durable and inexpensive. Moreover, there is a wide variety of colors, profile shapes and coatings of this roofing material. In our article we will describe all types of metal tiles, their characteristics and features of use to make it easier for you to choose the right coating.
Metal tiles are called roofing, which consists of a metal base with a certain profile and a protective layer of polymer material. The appearance of metal tiles is very similar to natural ones ceramic tiles. Thanks to this, a building with such a roof looks presentable and stylish.
Due to the structural features of the roof from metal tiles can last up to half a century. However, the durability of the coating is affected by the type of polymer protective layer and the aggressiveness of weather influences.
Important! Metal tile roofs can be made with a slope angle of at least 14 degrees.
As a basis for laying this material on the roof, a sparse lathing with a board or beam pitch of 0.3-0.5 m is used. If a sheet of metal tiles 0.045-0.05 cm thick is laid as a covering over such a lathing, the roof will withstand the load of snow cover of 250 kg per square meter, as well as the weight of a person.
It’s worth knowing: the main advantage of metal tiles over its ceramic counterpart is its lightness. So, ceramic products weigh about 40 kg/m², and metal material - approximately 5 kg/m².
Highlight the following types metal roof tiles depending on the base material:
If we list the types of metal tiles, it is worth mentioning that they may differ in size. So, different manufacturers produce products of different widths from 110 cm to 120 cm. The length of the sheet may also differ, which ranges from 80 cm to 8 meters. Sheets are usually made standard sizes, but at the request of the customer there may be exceptions to the rules.
Attention! When covering a roof with metal tiles, you need to take into account the weight of the material. The weight of the sheet depends on the type of coating used and the base material and can be in the range of 4-7 kg per square meter.
Exist different types metal tile profile. Also, products may differ in the depth of the flooring. Many of us have an idea of what Monterrey or Cascade tiles look like, but Lately many new high-quality products have appeared with interesting design. Let's take a closer look at the most popular of them.
Monterrey metal tile profiles have been familiar to us since the late 90s of the last century. This material began to be made in Russia from galvanized steel and with a relief, like ceramic tiles. But the founders of this material were the Finns. The appearance of Monterrey is quite recognizable by its rounded profiles and design in the form of asymmetrical and symmetrical steps. If you read the description of this variety, you can understand that when purchasing you get high-quality and inexpensive material. Its advantages include the following:
It is worth knowing: the profile dimensions of this type of tile with a sheet width of 118 cm are as follows: the wave height is 39 mm, and the pitch is 35 mm.
Thanks to special rectangular shape The Cascade wave tiles are very recognizable. It resembles a chocolate bar. The choice in favor of this type of coating is made by those who prefer savings, since the width of one sheet is significant. Cascade is a metal tile whose properties make it possible to cover roofs of complex configurations.
As a result, you will get a neat, strict and proportional roof in classic style. The product parameters are as follows: with a sheet width of 100-150 cm, the wave height is 2.5 cm, and the steel thickness is 1 mm. Among the advantages are:
The characteristics of Andalusia metal tiles are quite high, since they are manufactured using modern European equipment. Products with this name can be attached in a hidden way, which significantly improves the aesthetics of the coating. Moreover, thanks to a special lock, the sheets are joined as tightly as possible, which ensures reliable protection roofs from leaking. Advantages:
Classic shapes of metal tiles, rounded bottom and ridge parts - these are the main features of products called Joker. Those who appreciate classic types of tiles will definitely like this product with the correct wave and classic geometry.
If you are interested in original metal tiles, the types that appeared not so long ago will surprise you with their bizarre profile geometry, unusual design and increased wave height. The special profile configuration and significant wave height provide a three-dimensional effect of the coating pattern.
Products from this brand are distinguished by a reduced sheet width, which in no way affects its aesthetic characteristics. Thanks to improved technical specifications and appearance features, such sheets are best used for cladding high roofs big houses.
This variety is produced in China and has a tall, complex, symmetrical profile. It's quite original and fresh solution in the field of metal profiles. It is better to cover houses in a modern style with these types of tiles.
Metal tile coatings are needed not only to give the material a certain color, but also to protect it from moisture and other weather influences. The protective polymer film on the surface of the product significantly extends its service life. For this, various polymers are used that protect against temperature changes, burnout, moisture and increase the strength of the material.
So, today the following types of metal tile coatings are used:
As you can see, from a wide range of metal tiles, each developer can choose a product that suits its technical and aesthetic characteristics. Equally important is the wide price range.
When choosing metal tiles for roofing, developers solve several important problems at once, and one of them is cost. Moreover, the issue of price is important both at the stage of purchasing material and during transportation (the sheets are not particularly heavy) and at the stage of operating the roof along with the entire structure at the same time. Metal tiles allow reduce costs and ensure long service life(if the roofing work is carried out correctly).
Such a roof retains heat better (with proper insulation), does not burn and does not support combustion, the alloy of steel and zinc used in production perfectly resists loads (wind, snow, icing). A large selection of materials of various colors will perfectly fulfill the decorative function.
First of all, you need to make a reservation that this roofing material is used only for pitched roofs , and the slope should not be less than twelve degrees.
Metal tiles are produced based on thin cold-rolled steel sheet, processed by hot-dip galvanizing at metallurgical enterprises. Steel is susceptible to corrosion, and the addition of a zinc layer eliminates the interaction of iron and moisture; in addition, this alloy has increased strength characteristics. The thickness of the sheet for the production of metal tiles can be from 0.35 to 0.7 mm. Depending on it, they distinguish:
The raw materials (galvanized steel sheet) obtained from metallurgical plants are rolled, cut and then stamped in factories producing metal tiles.
Thus, the classification implies several more gradations: by profile shape and step size.
Galvanized metal is subjected to additional processing to improve performance. First of all, the galvanized surface is subjected to passivation procedures on all sides. Thanks to them, a special layer is created on the surface of the material, which is almost completely stops corrosion processes.
This chemical or electrochemical procedure is mandatory for roofing materials. Next is the passivation layer primed on both sides, and then the inside is covered with paint, and a special coating is applied to the outside polymer coating, which is made from various materials.
Perhaps, along with the quality of the metal used, polymer coating also greatly affects the quality finished product . Various types These coatings provide an aesthetically favorable, finished appearance of the structure, and this is an important factor. However, their main task, thanks to the additional protection of the metal from exposure external factors, extend its term service and maintain operational properties.
The technically complex process of coating prepared metal requires adherence to work technology and the use of high-quality rolled metal and polymer components.
Currently this is most widely used material, three-quarters of metal tile roofs have a coating of that substance. Perhaps the price played into the hands of this choice; polyester coating is not one of the most expensive types. Nevertheless, metal roof tiles coated with polyester perfectly withstand seasonal and daily temperature fluctuations, and resistance to ultraviolet radiation prevents rapid fading of the paint.
Polyester offers a wide choice of colors. But the coating thickness of 25 - 27 microns makes this choice not the most resistant to mechanical stress, that is, it is necessary to carry out fastening, processing and transportation work carefully, avoiding the appearance of coating defects.
This is a slightly more expensive look, perhaps due to more polymer consumption, which is applied with a size of 35 microns. Accordingly, the thickness of the metal tile is greater. The increase in size did not in any way affect the performance parameters; this type also tolerates temperature contrast well and is also very resistant to fading.
The difference is the coating added to the material metal dust, which allowed us to change the tone. If you don't like gloss, then you should choose matte version. It is difficult to answer which roof is better of these two options. The only differences are in appearance. You should also exclude mechanical damage when working with it, otherwise the metal tile will not last for a long time.
Covering with pural brings you closer to understanding what kind of metal tiles there are. Or rather, what it should be. Undoubtedly, pural is the most the best coverage rolled and stamped sheet. The thickness of the coating is 50 microns, it is based on polyurethane modified with polyamide.
A higher price means higher standards. Indeed, it is better to buy a product coated with pural, and get a high temperature range to which the roof will remain immune, additional protection from ultraviolet radiation present in the solar spectrum, immunity to the action of aggressive substances (for example, acid rain). And most importantly, she less susceptible to mechanical damage.
If the previous type has bright colors, then pural is matte has muted, noble shades. Otherwise, the parameters are similar; the customer chooses which coating to choose for the roof of a house under construction based on his own preferences, most often financial. The fit of the building into the surrounding landscape also plays an important role.
Metal tiles coated with budget and mid-price polymers offer a low price and a reasonable service life. The following substances used today have higher standards and performance characteristics, and as the characteristics increase, the price also increases.
Purex based coating has pleasing to the eye semi-matte shade, and by operational characteristics significantly superior to previous samples. The advantages include resistance to damage, ductility, and excellent corrosion resistance.
Today, metal tiles can be seen on a large number of roofs, both private houses and apartment buildings. The material has an attractive appearance, is durable and has many other advantages. But not everyone knows that metal tiles are available in a wide range. Moreover, it differs not only in color. What types of metal roof tiles can be found on the building materials market? By what main indicators do they differ from each other? This will be discussed in the article.
Today, a wide variety of materials can be used to cover the roof. But lately metal tiles have become the most popular. Why is this roofing material so in demand? The answer is quite simple, metal tiles have many positive qualities, namely:
Of course, we shouldn’t forget about safety. First of all, all types of metal tiles are not afraid of fire. From high temperatures The protective polymer layer may be damaged, but a fire will not occur. In addition, metal tiles are environmentally friendly. There will be no harm to the environment.
But there are also minor drawbacks. First of all, this is a quick failure if damaged protective coating. Some also consider the noise of the material to be a disadvantage. If it’s raining outside, you can hear drops “drumming” on the roof inside. But here it all depends on the sound insulation, or rather on the quality of its installation. 
Metal tiles have been used for roofing relatively recently. Just some ten to twenty years ago, slate or galvanized iron was mainly used. But these roofing materials have many disadvantages. The main ones are a short service life and unattractive appearance. Metal tiles are free of these disadvantages.
But don’t think that this roof covering option is easy to choose. Going into hardware store, you will see a huge one. And the species will differ not only in their color scheme, but also in many other parameters. The most important of them is the raw material from which this roof covering is made.
There are the following types of metal roof tiles, depending on the material used in production:
These three types of metal tiles are of varying popularity. The most popular is the steel version. And it's mainly a matter of cost. Covering a roof with steel metal tiles is inexpensive, and the service life is not much different from other types of material.
Types of metal tile coatings may differ in their profile. This is due to the way this type of roofing material is manufactured. The original sheet of metal, mainly steel, after being coated with a protective layer of zinc, is placed in rolling machine. Here, under the influence of the rollers, protrusions are formed, 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 improve the strength of metal tiles. 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 types:
The types of metal tile profiles are quite varied. Every owner of a private home can easily select suitable option. But when making a choice, in addition to appearance, you should also look at the profile height. The ease of installation and strength of metal tiles depend on this.
The external shapes of metal tiles can be different. Here, the owner of a private house will listen more to his taste and preferences when purchasing. But it’s worth remembering one thing: all types of metal tiles (at least those made from steel sheets) have a special polymer coating. It is this layer that performs a protective function. Of course, coating metal tiles helps improve its appearance. It is polymers that give roofing materials their color. But the main role This layer is precisely protective.
What types of metal tile coatings exist? Answering this question, experts will name the following approximate list:
As you can see, metal tile coatings can be very diverse. There is a choice both in terms of durability and cost. The most popular coating is polyester. Both glossy and matte versions of metal tiles last quite a long time, and are inexpensive. But here it is important not to damage the protective layer. That's why installation work must be done with extreme caution.
Today there is a large number of roofing materials. Each of them has its own pros and cons. One of the most popular roofing materials is metal tiles.
A roof made of this material is not afraid of temperature changes, and its installation can be carried out at any climatic conditions. Metal roofing is resistant to mechanical damage.
If necessary, the sheet of roofing material can be easily tinted or replaced with a new one. The rest of the article will discuss the main types of metal roofing tiles.
The following materials are used for the manufacture of metal tiles:
Copper metal tiles
Today there are many profiles of metal tiles. The following article will list the most common ones.
This roofing material is very similar to clay tiles, which is why it has become very popular. Monterrey tiles are an aesthetic, easy-to-install material that is well protected from natural influences.
Sheets of this material are made from high-strength steel, protected by a polymer layer. The Monterrey profile is perfect for roofing residential buildings. It should also be noted that the Monterrey metal tile profile has a smooth curve. The edge of the roof has the form of steps, located symmetrically or asymmetrically.
Sheets of this material will hold several layers. A protective polymer coating is applied to both sides of the sheet. Each layer of metal tiles has its own function:
This type of roof looks like a chocolate bar. The advantage of Cascade metal tiles is their low cost.
A distinctive feature of this material is the severity of its rectangular outline. Therefore, such metal tiles are good to use for roofs that have a complex shape. The Cascade profile looks neat, strict and proportional.
The main difference between Joker metal tiles and the most popular profiles (for example, Monterrey) is the smaller number of waves. Monterrey tiles have seven waves, while Joker has six.
Moreover, the materials have almost the same width. Due to this, the Joker metal tile looks smoother and more convex. A roof made of this material looks soft and textured.
This roofing material is perfect for public buildings, private houses, shopping pavilions and industrial buildings.
Joker metal tiles are made from galvanized steel High Quality, protected by a polymer composition.
The profile of this material has a rounded rowing shape and a flat sole. Banga tiles differ from other types of tiles by their higher profile height.
This property gives Banga metal tile roofing architectural expressiveness and exclusivity. Therefore, it is often used as a roofing covering for luxury country cottages. This material can be laid on roofs with a slope angle of 14 degrees. Banga metal tiles are resistant to large snow loads, because it has great height profile.
This type of metal roof tile appeared on domestic market recently. main feature metal tiles of Andalusia - a method of attaching sheets to each other and to the sheathing. There is a Z-shaped lock at the bottom of the roofing sheet. This ensures a tight fit of the sheets to each other.
The coating of the sheets can be matte or glossy. It is made from polyester, pural and other materials. This tile has many shades.
Andalusia metal tiles are made from galvanized steel. Several layers of primer and polymers are applied to the metal. These layers provide protection against corrosion, moisture and ultraviolet radiation.
Andalusia tiles have the following advantages:
This metal tile began to be manufactured in Russia quite recently. It has a high symmetrical profile. It should be noted that the equipment used to produce Shanghai metal tiles can be used for the production of corrugated sheets. To do this, it is necessary to distinguish the stamping device on the line.
This metal tile has many positive qualities. The main advantages include:
Shanghai metal tiles have an original profile geometry. This type of metal roofing tile looks great on almost any building because it has a high profile. Thanks to the symmetry of the pattern, this tile looks elegant and strict.
