Which metal tile is better to buy - coated or uncoated? Metal tile coatings - why they are needed, varieties, subtleties of material selection Metal tiles textured or decorative coating
Metal tiles are sheet construction material, used to cover the roofs of houses. To give it an attractive appearance, it is painted with various paints and primers. The service life and cost depend on the thickness of each applied layer. Some increase its resistance to corrosion, others protect it from mechanical shocks and ultraviolet radiation.
- Steel sheet.
- Galvanized on both sides.
- Passivating layer on both sides.
- Primer.
- Decorative and protective layer on the front side.
- Protective layer on the back.
Types of coatings and their characteristics
There are many types of paints. They are made from the same components, but using different technologies.
Produced on the basis of the following substances:
- polyester;
- polyurethane;
- plastisol.
1. Polyurethane.
The sheets are painted in a layer of 50 microns. Galvanization is carried out in the range from 100 to 570 g/m2. Tiles with such a coating are produced by some of the most famous and best brands: Armakor, Granite, Prism and Pural. They are similar in characteristics, differing only in the country of origin. When polyurethane is applied, the surface acquires a silky-matte tint; it is resistant to ultraviolet rays, so it retains its original color for a long time. Not afraid chemical substances, which are formed in excess in major cities.
Such metal tiles are good even in harsh conditions, for example, near the seas, where there is often salt fog. It cuts perfectly, and when bending, no cracks form in the paint; as a result, the protective layer remains completely intact. The service life of Pural, Granite and Prism ranges from 20 to 40 years. The manufacturer provides a guarantee of up to 35 years, depending on the thickness of the steel and the galvanization layer.
Puretan is one of the varieties polyurethane paints. Applied with a layer of 35 microns, galvanizing - 275 g/m2. Due to the smaller thickness, the cost is lower. Can be used in difficult climatic zones.
Prism - coating 50 microns thick, galvanized - 142-258 g/m2. But in this case, to protect against rust, it is not 100% zinc that is used, but its mixture with aluminum. Thanks to this, the tiles lie well in places with high humidity, and is also resistant to salts, chemical acids and alkalis. Will last from 25 to 30 years, guarantee period- 20 years.
Quartzite Mat is applied in a layer of 50 microns. Galvanization is carried out with a thickness of at least 275 g/m2. WITH reverse side dyed with polyester to improve appearance material and additionally protect from negative impacts. Service life - 45-50 years, factory warranty, subject to compliance with roof installation technology and rules of use - 35 years.
Polyurethane products also include the following brands: Granite, Purman, Steel Cashmere and Quartzite Light.
2. Plastisol.
It is applied with a layer of 200 microns, galvanization can be from 100 to 258 g/m2, the base is polyvinyl chloride. Looks good on any type of roof and withstands precipitation well. But in intense sunlight, it loses its original color and the paint slowly begins to crumble. The service life is 25-35 years. The warranty can be up to 30 years, but this depends on the manufacturer, the thickness of the galvanized layer and the steel.
3. Normal and matte polyester.
It is one of the cheapest coatings, and it also has the widest color scheme. Its base is polyester paint. Painted tiles have a glossy sheen and are resistant to precipitation and ultraviolet radiation. It is not recommended for covering roofs in places with a polluted environment, for example, near highways, in large cities or near industrial enterprises. The most well-known brands are Satin, Steel Silk, Atlas, Polydexter, Purex and Agneta.
Satin – applied in a layer of no more than 25 microns. For the manufacture of tiles, galvanized steel from 100 to 570 g/m2 is used. Service life is 10-30 years, the warranty varies, it all depends on the manufacturer.
Agnetha, unlike previous options, is applied to the product on both sides, thereby better protecting it. The front layer reaches 30 microns, the back layer – 25. Galvanized steel of 275 g/m2 is used. A special component has also been added that gives a copper tint. Resistant to ultraviolet rays, service life - 35-40 years.
Matte polyester is applied in a thickness of 25 to 35 microns. Polyester paint is also used as a base, but it is matte, so it does not have a glossy sheen. But unlike Pural or Plastisol, it poorly withstands mechanical loads and burns out quite quickly. The service life depends on the manufacturing technology and manufacturer.
Most famous brands coated with matte polyester are Steel Velvet, Safari, Viking, Drape and Velor. It is not recommended to use them in places with an aggressive environment.
You should check the thickness of the galvanization, since the service life depends on it: the thinner, the less the metal will last. This is where manufacturers are trying to reduce product costs and increase the frequency of purchases of new building materials. It is better to choose tiles at a high price and with a long warranty. In this case, the roof will have to be repaired again in 20-25 years.
A material with a textured (matte) surface fades much slower than a glossy one, even if it has only one layer of polymer.
Cost and what affects it
The price varies greatly depending on the thickness of the steel: the thinner it is, the lower the cost of the building material. The type of metal and the level of its purification also influences. Prices also increase depending on the size of the galvanized layer. Well-galvanized tiles are more resistant to corrosion, and subsequent coloring and protective coatings adhere better to them.
The following factors also affect the cost:
- Profiling technology (giving steel final form, increasing rigidity and load resistance).
- The presence of a passivation layer.
- Type of coating.
- Composition, degree of adhesion and thickness of the primer.
- Wave height (the higher, the more expensive).

Home owners often have a question about what to buy – tiles or soft roof. These building materials differ significantly in the production method. The second one should be chosen when the home owner has an unlimited budget, since it costs more. To install it you will need to buy Additional materials for arranging a continuous sheathing.
If you plan to purchase an expensive metal tile and you are not sure that you will be able to install it well and correctly yourself, then it is better to contact a construction company. You should choose an organization that has proven itself well and has a large number of positive feedback. You need to make sure that she does all the work conscientiously. Regardless of what kind of tiles are used, if the installation technology is violated, then within a year or two it will begin to rust. It is necessary to handle its protective coating especially carefully, as it is easily scratched.

Metal tiles began to be used as a roofing material not so long ago. But this material has already proven itself with the best side. Metal tiles are practical roofing, which is lightweight, easy to install and cost-effective.
During the construction process, contractors will have to consider several options for metal tile products and, based on the performance properties of each type, make their final choice. In this article we will describe what types of metal tiles there are.
Metal tiles - varieties
Types of tiles vary depending on:
- base material;
- coatings;
- shape and profile height.
The base of the tile can be steel or aluminum. Most manufacturers prefer the first type of material. The sheet thickness does not exceed 0.5 mm. To counteract corrosion, the steel base is covered with a protective shell of basalt chips, aluzinc or zinc. Aluminum base is a more expensive solution, but at the same time, such tiles are lightweight and durable. Therefore, they are often made for home use. This base is also covered with protective agents.
In addition, modern manufacturers of metal tiles, using innovative approaches to production, offer another type of base - copper.
Metal tiles - types of coatings
No less important role The type of metal roofing also plays a role.
Among the main materials are:
- polyester (glossy or matte);
- plastisol;
- pural;
- PVF-2;
- Terra Plegel.
The most common metal tiles are coated with polyester or plastisol. Less commonly used are matte polyester and pural. The least widespread are tiles coated with PVF-2. The reason for this situation lies in the disadvantages and advantages of each material, high cost and availability on the market.
We list the main properties of each type of coating:
- Polyester . It is characterized by low cost. The material is sprayed onto the front side of the metal tile sheet. As mentioned above, there are matte and glossy types. has a thickness of 25 microns. This coating is quite sensitive to mechanical stress and is subject to gradual fading. At the same time, glossy polyester is the only type of coating that allows you to paint tiles. Matte polyester has a thickness of 35 microns. This coating is more resistant to mechanical stress.
- Plastisol . Like the previous type of coating, it has a low cost. The polymer is applied by rolling a plastic film onto a steel surface. Metal tiles coated with plastisol are excellent for regions with humid and temperate climate. At the same time, it is not recommended to use such metal tiles in regions with sudden temperature changes.
- Pural coating . The basis of the material is polyurethane. The thickness of the protective layer of 50 microns allows it to withstand mechanical stress, ultraviolet radiation and precipitation. The cost of pural is not too different from plastisol. The only drawback of this polymer coating is small selection possible roof colors (more details: " ").
- PVF-2 (polyvinyl fluoride). It has the richest color range among all presented types of coatings. Able to withstand high temperatures and does not lose its color. The purchase of tiles with such a coating is carried out only to order. The cost of tiles coated with PVF-2 is more expensive than when using plastisol or polyester.
- Terra Plegel . The coating is almost never used on the domestic market. This material gives metal tiles the appearance of a natural clay roof. Apply by spraying quartz sand onto molten plastisol followed by application of a paint layer. Due to this method of application, the weight of the tiles increases by 40-60% (be sure to read: " ").
Profile shape and height
Depending on the profile shape, the following types of metal tiles are distinguished:
- with a symmetrical wave;
- with an asymmetrical wave.
Tile manufacturers use different stamps, the depth of which affects the height of the roof profile.
Standardly, there are 3 types of metal tile profile depths:
- 28 mm;
- 45 mm;
- 52 mm.
The metal tile with the smallest profile is called “flat”. This material is most often used when constructing a metal roof with your own hands. The wave pitch of metal tiles affects the rigidity of the sheets.
Storage conditions
Polymer-coated metal tiles must be stored under certain conditions until they reach the roof. After purchasing, the tiles should be properly transported to the place of storage and construction, and then the roofing should be installed.
We list the basic rules that help protect material during storage:
- It is recommended to store sheets in a closed, dry room;
- contact of tiles with chemicals, sunlight, water, and soil should be avoided;
- tiles purchased in their original packaging should be stored on a flat surface. At the same time, it is laid on a beam 20 cm thick, and the interval between the beams should be about 50 cm;
- If the tiles will be stored for more than one month, then the sheets should be laid with dry slats. The height of such a stacking standard can reach 70 cm.
Installation of metal tiles, detailed video instructions:
Separately, mention should be made of the protective film that is applied to the surface of the tiles to protect them (not to be confused with polymer coatings):
- The shelf life of metal tiles with a protective film applied is 1 month;
- the protective coating should be protected from exposure to sunlight, otherwise under the influence of temperatures it may melt into the sheet and it will not be so easy to remove the film;
- protective film removed at average air temperatures. When working in conditions of low or high temperatures, there is a very high probability of leaving pieces of film and adhesive on the surface of the tiles.
If all storage conditions for metal tiles are met, they will retain their performance properties for a long time. This allows you to organize the construction of a complex rafter system without regard to time constraints.
Metal tiles, the types of which were mentioned today, allow you to create durable roof, With high performance durability and efficiency. Thanks to the variety of protective materials and profile shapes, you can choose the roofing covering that can fully satisfy your requirements.
This is an important parameter on which the strength of metal tiles primarily depends. This is especially important in our climate, because excessive snow loads can easily lead to deformation of a sheet with insufficient thickness. In addition, thin sheets are easily damaged during installation. Manufacturers are also guided by this, establishing a longer warranty period for more durable metal tiles. For the roofing of a house, sheets with a thickness of 0.5 mm are mainly used. If you plan to use the material to cover a gazebo or shed, a thickness of 0.4 mm is suitable.
One of the ways to protect metal tiles from corrosion is double-sided galvanization. steel sheet. The zinc content in the metal can vary from 80 to 275 g/m2. The thicker the zinc layer, the longer the roof will last.
Sheet coating
An equally important indicator of a metal roof is the type of protective polymer layer, which affects the appearance of the sheets and creates additional protection. Main types of polymer coating:
Polyester. Coating thickness - 25 microns. Most budget look coatings with good ductility. Polyester is the least resistant to mechanical damage and ultraviolet radiation compared to other types of coatings. It can have either a glossy or matte surface.
Polyurethane. Coating thickness - 50 microns. Polyurethane has good resistance to mechanical damage and corrosion, as well as resistance to fading and frost resistance. The texture of this coating can be glossy, matte or semi-matte. The guarantee for such metal tiles is different manufacturers can reach 35 years.
Plastisol. Thickness - 200-250 microns. This coating is most resistant to mechanical stress, has high corrosion protection, resistance to UV and heavy climatic conditions. Due to its plasticity, the coating has the ability to self-heal. Plastisol has a glossy or semi-matte texture and, as a rule, is a premium coating with the longest warranty period.
Pural. Thickness - 50 microns. Pural is made from polyurethane resin using a primer. The coating is almost not subject to deformation due to its high strength characteristics and consists of nine layers, including zinc and polymer coating, primer and protective paint.
Sheet profile
The shape and height of the profile determine the rigidity of the sheet: the higher the profile, the metal tiles are more reliable. The most universal is the S-shaped profile with a height of 25-45 mm. This option is suitable for most roofs. The most popular metal tile profiles are Monterrey, Classic and Dune. The first one imitates natural clay tiles and has a large step width and excellent bright design. The Classic profile usually has a smaller pitch. The classic is well distributed and is close to the profile of ceramic tiles. Dune is similar in appearance to Monterrey tiles. The profile does not have holes on the surface of the sheet, which increases the service life of the roof. In addition, Dune metal tiles do not require maintenance.
Accessories
When purchasing metal tiles, you must remember that it is impossible to do without additional elements roofings, such as ridge elements, end and eaves aprons, seals, abutment strips, snow retainers and fasteners. All these elements will help give the roof a finished look and protect complex components from leaks.

We compare one model of metal tiles with different coatings
Which metal tile to choose with a glossy finish or a matte finish? Very often our clients ask this question, both to themselves and to us. If you visit our products section, you will find a position in it - metal tiles, and in it there are two subsections Monterrey polyester and Monterrey matte polyester. As you can see from the banner of these sections, matte metal tiles are more expensive than glossy ones, let's talk about the main differences between these materials.
Matte and standard (gloss) polyester
We would like to explain to you the main differences between the coatings in simple language, but we cannot do without resorting to the language of terminology and a certain abstruseness. So.
Coating standard polyester And matte polyester are produced on the basis of one technology - polyester-based coating. That is, in general, one technology, but with certain features.
Standard polyester in the process of its production receives following parameters– withstands high temperature air and resists corrosion. This material is durable and its service life is from 10 to 30 years. True, these figures are relevant under one condition, that the zinc content of this metal is at least 200 g/m2.
Matte polyester- everything seems to be the same as standard polyester, only the appearance is completely different. The surface of matte polyester has microscopic irregularities and due to this, sunlight is reflected differently and the surface does not shine. This surface has the appearance of a more natural (natural) material. The matte coating itself has a thicker layer (35 microns), although the chemical composition itself is the same as that of standard polyester. If the main parameters of matte polyester have maximum indicators - metal thickness and zinc content, then such a coating will last about 40 years.
As you can see, with the general technology based on polyester, the material has different period service and naturally has a difference in price.
Matte the material is more expensive with more high performance, this is understandable, because it is intended mainly for roofing.
Standard ( gloss) polyester, a material with lower technical performance and, as a result, cheaper.
Based on these findings, a simple conclusion can be drawn - matte polyester is better than gloss. But such conclusions can be drawn in a simple world, but our world has changed, the main thing in it is marketing and the ability to sell, so everything has become a little more confusing and complicated.
The complexity of the situation is that material manufacturers understand that consumers want more quality material, but at a low price. And they learned to give it to the consumer, or rather, to create the illusion that they provide such material.
Therefore, there is matte polyester on the market with a thickness of 0.45 mm and a zinc content of 140 g/m2. This material looks like a high-quality raw material, but it is not entirely suitable for a durable roof - this is its disadvantage. But on the other hand, in our country, where the construction of fences from corrugated sheets is developed, this perfect material for the construction of fences.
What coating to choose for metal tiles
If you choose a material for metal tiles for a residential building, then it is clear that its parameters should be to the maximum. But there is another important component here - price. And in this matter, everyone makes their own decision.
Matte material theoretically has better performance, but market realities show that this is not always the case.
Gloss or standard polyester is more attractive in price, but if you find such material in a thickness of 0.5 mm and with a zinc content of 225-275 g/m2, then you can say with confidence that it will be in no way inferior to matte polyester.
So, which metal tile is better - matte or glossy - can only be determined by a quality certificate for this material, the main thing is that it is genuine.
For you, as a client who chooses metal tiles for the roof and takes the quality of this coating seriously, it is also a good idea to remember about the appearance of the roof, because the most main criterion when choosing metal tiles, you should like them.
Metal tiles in black, a rarity on our roofs
Matte or glossy metal tiles – which is better?
Metal tiles are very popular in the roofing materials market. Its advantages include a solid appearance, reasonable price-quality ratio. It looks equally good on modern structures and buildings ancient building. If you have chosen metal tiles, you have to decide which variety to choose - glossy or matte? Let's look at the differences between these two types of coverage.
Comparison of glossy and matte coatings of metal tiles
Both types of coatings are polyester, produced using the same technology, and have the same chemical composition. However, matte metal tiles are more expensive than glossy ones. What is the reason? Differences between matte and glossy metal tiles:
- The matte finish has textured surface irregularities. As a result, it reflects the sun's rays less and has no shine.
- The thickness of the rough coating is greater than the glossy one and is 35 microns.
The cost of metal tiles is influenced not only by the coating, but also by the thickness of the steel sheet and zinc protective layer. The larger they are, the more expensive metal tiles cost. Therefore, the quality of the roofing material will be best when combining a rough coating with the maximum acceptable values thickness of steel sheet and zinc layer. The cost of such metal tiles is also significantly higher.
At the same time, manufacturers produce matte metal tiles with a sheet thickness of 0.45 mm and a zinc content of less than 200 g per square meter. It looks expensive, but costs much less. Its service life is also shorter. Therefore, in order to choose a high-quality roofing material, you need to familiarize yourself with its technical characteristics specified in the quality certificate. Metal tiles with a glossy finish, but with a sheet thickness greater than 0.45 and a zinc content of more than 200 g per square meter, are not inferior in quality to rough ones.
The choice of buyers is significantly influenced by the appearance of the roofing material. A house with a roof made of rough metal tiles looks more solid and presentable. But not all buildings need this. Therefore, when choosing the type of metal tiles, you should give preference to quality and durability, as well as the best combination technical characteristics and cost. After all, the roof must reliably protect the house from any bad weather.
Matte or glossy metal tiles - which is better? BrandMET, Production, corrugated sheeting, metal tiles
The MarkaMet company in Krivoy Rog offers you the best roofing materials at the best price. The company produces corrugated sheets and metal tiles. Most a large assortment in the city.
Which metal tile is better - what to look for when choosing
Metal tiles are a widely used roofing material made from galvanized steel. It looks great in appearance and follows the terrain ceramic tiles However, it has significantly less weight, is able to withstand large mechanical loads and has high resistance to moisture.
All these qualities make metal tiles indispensable for use in the construction of private houses. This article will focus on which metal tiles to choose and what points to pay attention to when choosing a material in each specific case.
Structure of a metal tile sheet
Metal tiles are ideal for the construction of private houses, country cottages and small townhouses. Due to its low cost, long service life and high technical characteristics, the material becomes preferable to slate, roofing felt or ceramic tiles.
The metal tile sheet has the following structure:
- Made from high quality steel. The thickness of the steel reaches 0.45-0.9 mm. An indicator of 0.5-0.6 mm is enough to give the roofing material sufficient strength and load-bearing capacity.
- Zinc coating. This coating improves the anti-corrosion properties of the material. The layer is considered normal zinc coating at 275 g/m2.
- Primer mixture. A primer on both sides of the sheet is necessary to improve adhesion with the polymer or paint applied afterwards.
- Decorative layer. Decorative is applied to the sheet from the front side. polymer layer. Any decorative coating enhances the protection of the sheet from water and mechanical influences, and also gives the material a certain color.
- Varnish coating. A layer of varnish is applied to the back of the sheet to protect it from rusting.
What types of coverage are there?
When deciding which metal tile is better, it is worth keeping in mind that its cost and specifications, as a rule, will depend on the type of decorative layer. Once upon a time, paints were used to cover metal tiles, but due to their poor resistance to sunlight and temperature changes, they were replaced by polymer materials, which gave the material a longer service life.
The following types of polymers are used as a protective layer:
- Polyester. This polymer has high protection against ultraviolet radiation, temperature differences, and also good anti-corrosion qualities. You can obtain matte and glossy coatings suitable for use in regions with any climate.
- Pural. The pural layer is distinguished by its high strength and long service life - largely due to the fact that cracks do not occur in the material during bending.
- Plastisol. Materials coated with plastisol have a more pleasant appearance. Thick layer plasticizer makes it possible to create embossing, improves stability and increases the service life of the roof.
- PVDF. This polymer gives metal tiles a metallic effect. Highest strength and resistance of the material to aggressive external environments makes it possible to use it for industrial purposes.
If you have not yet decided which metal tile is better - matte or glossy, then keep in mind that, in any case, it is better if the material is polymer-coated. Such metal tiles cost a little more than the painted version, however, its technical characteristics significantly exceed those of cheaper analogues.
What parameters affect quality - which one is better to choose?
Currently in construction stores You can find a large number of different metal tiles, both in price and quality. To better understand which metal tile is best for your roof, study in detail all the technical and operational characteristics. They will tell you about the quality. Remember that the most expensive product does not always have best quality. Also take into account the ratings of metal tile manufacturers.
In addition, you should take into account the following characteristics:
- Thickness. High-quality products must have a thickness of more than 0.5 mm. Varieties of metal tiles with greater thickness have increased strength, however, they have more weight. This parameter should be taken into account when designing a roof truss system.
- Zinc coating thickness. There are three categories of this indicator on the market: “economy”, “standard” and “premium”. A zinc coating thickness of 275 g/m2 is considered sufficient. The higher this value, the longer such material will last, and the more expensive it is.
- Type of decorative layer. There are brands of metal tiles with paint and polymer coating. It can be either glossy or matte tiles. The painted version will cost less, but will not last as long as polymer-coated material.
- Does the material have a certificate of conformity?. The manufacturer must provide the entire list necessary documents, indicating the quality of metal tiles. Otherwise, it’s better not to trust such a manufacturer.
It is worth noting that the best proof of the quality of a material is its appearance. Before purchasing, be sure to visually inspect the metal tiles. It should not have chips, scratches or uneven edges, which are likely to cause early damage to the roof.
Glossy or matte - which metal tile is better?
What is the first thing people notice when driving past a house? On the roof! If it is well-groomed, modern, without black streaks or cracks, passers-by will immediately understand that this cottage belongs to thrifty and knowledgeable people.
Metal tiles - roof decoration
The construction industry offers a huge selection of roofing materials, but if you pitched roof, then the optimal option, both in terms of quality and price, is metal tiles. It has a quite decent appearance, its service life is tens of years, good producers and serious sellers provide a 7-15 year warranty (subject to compliance with installation requirements).
In Belarus, Grand Line metal tiles, which are produced at the Russian Metalist plant, are in great demand. Its advantages:
- affordable price;
- a wide selection of collections of various shades and with different profile patterns;
- use of high-quality hot-dip galvanized sheet steel;
- usage polymer coatings, which do not fade under the influence of solar radiation.
Grand Line metal tiles in Minsk are supplied directly from the manufacturer, so prices are lower than the market average.
Glossy metal tiles
Several layers of coatings are applied to the corrugated sheet to improve its anti-corrosion properties. The gloss glows brightly in the sun, making your home stand out. Even if you look at satellite images on Google maps, houses with glossy roofs sparkle in the sun.
Glossy polyester paint is not just a fad; it reflects a large percentage of thermal energy, so the roof does not overheat on hot days. The only negative is that any damage will be noticeable.
Matte tiles
The difference is that polyester paint with metal shavings is used for painting. The roof will not shine so noticeably under the sun's rays, but the shavings will give the coating additional strength and durability.
Another big plus of matte metal tiles is their color resistance to fading. If we talk about prices, they are approximately the same. The choice depends entirely on the owners of the house. When ordering roofing, pay attention to the following facts:
- steel thickness - not less than 0.5 mm;
- preferably a well-known brand: Metalprofile, Grand Line, Pruszynski, Ruukki, etc.;
- durable polyester coating.
Glossy or matte
Glossy or matte - which metal tile is better? What is the first thing people pay attention to when driving past a house? On the roof! If it is well-groomed, modern, without black streaks and cracks,
