The texture of metal tiles - color, types and shape of the profile. Unique style and elegance - matte polyester Red tile texture

The use of metal tiles in the arrangement of roofs, homeowners began relatively recently. Despite this, this roofing material has proven itself with positive side, because thanks to its use it became possible to create a reliable and durable coating.

What is a metal tile?

The metal tile is made of steel - aluminum-zinc and galvanized. The profiled method of rolling metal production allows you to create sheets roofing material correct geometric shape. Most upper layer metal tiles perform a decorative function and at the same time protect against adverse effects environment. For example, a metal tile with crumbs, the color choice of which is simply huge, can become a home decoration.

The popularity of the material is due to its advantages, including:

However, like everyone building material, the metal tile has not only advantages, but, unfortunately, also disadvantages. Most often, the main inconvenience faced by consumers during its operation is high level noise when it's raining. In addition, the surface of the roof can overheat in the summer in the sun. These problems are solvable: metal tiles with powder can significantly reduce noise and heat. Such material is more expensive.

Metal tiles are distinguished:

• by color;
• according to the profile form;
• by the height of the waves of the sheet;
• in appearance polymer coating.

Metal tile color

It depends on which color is chosen. appearance building. The shade that is preferred most often depends on the individual taste of the property owners. It does not matter whether there will be a red or blue metal tile, the main thing is that it serves for a long time and pleases with a rich color.

A few tips will help you decide on the tone of the metal tile:

• material dark shades fades much faster from exposure to ultraviolet radiation, therefore, if the building is not protected by tall trees, it is advisable to choose light-colored products;
• a metal tile with a high-quality coating, although more expensive, will last much longer, retaining its original color;
• desire to buy roofing cheaper can lead to the fact that after 2-3 years it will lose its shade, and the roof will become "spotted".

Usually buyers like natural tones: red wine, chocolate, green moss, graphite. Metal tile yellow, blue, black, gray, etc. found on buildings much less frequently.

Manufacturers in the designation of tones and shades of products adhere to single standard accepted at the international level. When painting, they indicate the color according to the RR or RAL scale. Each shade is indicated by a number, for example, it looks like this - RR 40, RAL 5005.

Types of polymer coating

If you look at samples of metal tiles with different types coatings, you can see that they are different, since different materials are used to produce the top protective layer.

Polyester . The basis for this coating is polyester paint, which has good durability for use in all climatic conditions. The material is produced in two versions - glossy and matte metal tiles. The main advantage of this coating is its low cost. Glossy polyester is applied to the sheet with a layer of 25 microns, and matte - 35 microns. While glossy products have a more attractive appearance, matte metal tiles are durable and resistant. color solution. This has a long service life - about 40 years.

Plastisol . The coating is based on polymers, including polyvinyl chloride, and therefore in a number of countries such products are considered environmentally unsafe. This metal tile is created with spraying, as a result one of the most durable coatings is obtained. The thickness of the plastisol layer is 200 microns - this is quite reliable.

Pural . This coating is produced using polyurethane, polyamide and dyes. The material is resistant to ultraviolet, mechanical damage and environmental influences. Products are able to withstand huge temperature drops from 45 degrees below zero to + 120 degrees. In case of need for repair, metal tiles with this coating can be painted. The layer thickness is 50 microns.

PVDF . It has high resistance to corrosive processes and atmospheric influences. Manufacturers add a special pigment to the coating composition, which gives the surface of the material hardness and shine. The layer thickness is 25 microns. The service life is less than that of other types of protective layer - it does not exceed 25 years.

Polyvinyl fluoride . This coating has the largest color gamut. Such roofing material is elastic, does not exfoliate, and is resistant to high and low temperatures. The color of the coating does not change under the influence of ultraviolet radiation and atmospheric precipitation. Metal tiles, which have a high-quality polyvinyl fluoride coating, cost 10 percent more than other types. The layer thickness is 30 microns.

P50 . It is a type of polyurethane and has a coating thickness of 50 microns. Such roofing products are able to withstand both high and low temperature. Under the influence of ultraviolet does not fade. If necessary, during the repair of the roof surface, additional layers of paint can be applied to this coating. The weight of such a metal tile is greater than that of products with the above types of protective layer, it is almost 6 kilograms per one "square" of area.

The height of the waves on the metal tile

On a metal tile for a roof, waves can be of two types: small or high (see photo). If the height does not exceed 5 centimeters, the wave is considered small - this version of the product is used in the construction of buildings for various purposes. The product looks great and the price is very reasonable. A large wave is considered to be a wave height exceeding 5 centimeters. Such a metal tile in the domestic building materials market belongs to elite products and therefore its price is higher.

Types of metal tiles, in detail on the video:

Profile shape of the metal tile

The most common option metal tiles- This is a material with an asymmetric beveled wave. On sale you can also find products with a symmetrical wave, but few companies make it. At first glance, it may seem that there is no difference between symmetrical and non-symmetrical waves, but after the material is already installed on the roof, the differences become noticeable.

Cutting tool

To cut sheets of metal, you can use traditional metal cutting tools, such as:

The height of the wave and the type of coating to decide how to cut the roofing material does not matter - you can use one of the above tools. When working with power tools, you should not forget about safety precautions.

Often, manufacturers in the instructions for the metal tile warn that it is strictly forbidden to cut it with a grinder, since the metal at the cut point heats up to such high temperature that the protective layers of the sheet are destroyed and as a result of this, a corrosive process begins, which will very soon make the roofing unusable. Experts advise before starting installation to familiarize yourself with the recommendations of the manufacturer of products of a particular brand.

The production process of metal tiles

The manufacturing process of this roofing material is as follows:

• rolled steel sheet;
• coatings and a protective layer are applied;
• profiling is done.
• the product is packed.

In the domestic market of building materials Russian companies offer metal tiles with a thicker base - at least 0.55 millimeters. Such a material is durable, but has a number of significant drawbacks: it is difficult to form it, deviations may occur in the configuration, and hence it is impossible to achieve high-quality sheet joints.

Most the best option the thickness of a sheet of metal with a size of 0.5 millimeters is considered, which makes it easy to form a product and has high strength characteristics.

Coating and protective layers of metal tiles. Each layer of coating is designed to protect against corrosion and fading under sunbeams. They give the roofing material beautiful view. The period that a galvanized metal tile can last depends largely on the quality of the coating that protects the product.

Today, the application of layers to the base is fully automated, the work is done in the following order:

• passivation;
• primer;
• polymer composition;
• varnish coating.

The polymer composition is applied to the metal tile only from the outside, and a protective colorless coating is performed on the back.

Profiling. After applying the protective layers, the product is sent to the molding shop to give the product a profile. Then the metal is cut into individual sheets of a certain size and packaged.

The sizes of a sheet metal tile make from 0,5 to 6 meters. The most popular products include products with a length of 3.5 - 4.5 meters. Fixing short sheets takes a lot of time, and too long sheets are accompanied by certain difficulties.

The weight of the metal tile and its dimensions

Square meter such a roofing material is approximately 5 kilograms, it depends on the thickness of the base (metal sheet) and the type of polymer protective coating (read: ""). To get a strong, reliable and durable roofing material metal blank subjected to various manufacturing processes. As a result of multi-stage and complex actions, a modern metal tile is obtained - the texture of which and the color scheme are very diverse.

Recently piece metal tiles have appeared on the domestic market. Unlike sheet imitation of natural tiles, it provides better ventilation of the base on which it is attached and is not subject to deformation during temperature changes, and during installation it allows you to make different color patterns from individual small-sized tiles.

"Velvet" surface;
Reflects light and does not give glare;
High color fastness;
Increased resistance to chemical attack;
Increased resistance to UV radiation and mechanical damage.

Matte polyester - a polyester coating that has the abbreviation PEMA (sometimes REM or MPE is also found). Its thickness is 35 microns, so it is more resistant to mechanical damage than ordinary polyester. The metal tile coated with matt polyester is also resistant to ultraviolet radiation, withstands high temperatures (up to 120 degrees), it can be processed even when negative temperature(down to -10 degrees Celsius).

Matte polyester has good anti-corrosion properties, so metal tiles with such a coating can be used in various climatic conditions. Matte polyester is plastic, which gives greater freedom in the formation of the roof. This is the only polymer coating that has a noble matte finish and does not shine.

It does not lose its color for a very long time, and although it has a very limited color scheme, is very popular with those who want to give a noble look to the structure, which is especially important, for example, for houses in the resort area.

Matte polyester has the property of equally little reflection sunlight regardless of the angle of incidence of the sun's rays.
This coating is recommended for use in any climate zone for surfaces on which the presence of glare and gloss is undesirable.

It has not been used as a roofing material for a very long time, but the service life declared by the manufacturers has already been confirmed. At the same time, not only due to high user qualities, but also due to the amazing diversity.

Let's first talk about the structure of a metal roof. The device of roofing material is not at all as simple as it seems at first glance. Despite the relatively small thickness, this composite material, in which each layer performs a significant function.

• The basis of a metal tile is most often a steel sheet with a thickness of at least 0.45–0.5 mm. With a thickness of 0.4 mm, the strength of the product drops noticeably - by 45%, so this parameter should be clarified. MCH is made from cold rolled steel, which leads to very high strength.
• The sheet is hot-dip galvanized. Zinc, unlike iron, does not corrode. Applied with a layer of sufficient thickness, it protects the product from moisture. The optimum consumption for galvanizing is 275 g/sq. m. However, this value is relevant for medium-sized regions. So, in severe winters or proximity to the sea, the zinc layer should be larger - the consumption is not less than 350 g / sq. mm. A thinner one may not perform its functions.

The sheet is galvanized on both sides, so the tiles are protected from condensation on the one hand, and from rain and snow on the other. The product marking indicates the amount of zinc used in galvanizing - 60, 80, 275, 450 and so on.

• The primer layer is 15 microns thick, no less. The material also protects the zinc layer from possible mechanical damage and increases the adhesion of the metal to the external decorative coating.
• On the back side, the MCH is additionally protected with a transparent varnish, since here the product does not carry a decorative load.
• A polymer coating is applied to the outside. The composition performs both an aesthetic function and a protective one. In this capacity, different substances are used:
  • polyester practically does not fade in air and tolerates significant temperature changes, so this coating is suitable for any climate. An additional plus is the possibility of repair in the event of scratches, a minus is some fragility of the material. Matte polyester is more resistant to UV radiation;
  • pural- can also be matte or glossy. Resistant to mechanical stress, in particular to bending of the material during installation, for example. In terms of resistance to temperature and moisture, polyester is not inferior, but besides, it is chemically inert and is not afraid of a large amount of salts - in sea air, for example;
  • plastisol- the coating contains a plasticizer, which increases the resistance to scratches and chips and provides the possibility of self-healing. The material does not lose its luster over time, but fades under the influence of too intense sunlight;
  • PVDF- a mixture of acrylic and polyvinyl fluoride, is highly resistant to chemically aggressive substances, so the coating can be used in industrial areas. PVDF perfectly "holds" decorative effects- glossy, "metallic" and so on.

We will talk about the composition of the roof (roof) from metal tiles later.

The specialist will tell you about the hardships of choosing a metal tile in the video below:

The composition of the MCH

Zinc is not independent material, and an obligatory protective layer. It is he who protects the steel from corrosion, which leads to a long service life.

• Zinc-titanium- in this case, they are dealing with an alloy, which includes zinc, titanium, as well as aluminum and copper. This material is absolutely not subject to corrosion, although after 5 years it becomes covered with a patina, losing its bright silvery sheen. Extremely strong and durable: average service life is 100 years. The material is often used for roofing complex elements, since zinc-titanium MC perfectly combines flexibility and strength.
• Roofing copper- the tile here is a private option, or rather, the material is made in the form of a tile. However, the advantages of copper do not decrease from this: durability - more than 100 years, absolute resistance to corrosion, and this also applies to weather factors and chemical aggressive substances. Over time - 5-10 years, copper is covered with a greenish patina, which gives the building a touch of noble antiquity.

The disadvantage of copper is softness, low mechanical strength. However, there is a downside to this - the ease of repair: at any time and in case of any damage, copper can be patched and welded.

• Aluminum– does not corrode and does not need any protection: aluminum oxidizes instantly and the oxide layer is 100% protection. The material is very light, durable - 100-150 years, just like copper reflects heat. Thanks to this, the building does not overheat in summer, and in winter the coating does not allow snow to accumulate.

Most often, aluminum is not coated with paint, unless the MCH imitates some other material - real tile or wood. The natural color and luster of it is quite attractive.

Appearance

Metal tile is much more diverse in design than ordinary. You can choose the color, and texture, and form factor, or even choose an imitation of some other material.

Profiles

They are somewhat conditional. The names are most often associated with the name of the brand that produces such a product, or with the nature of the profile.

• Monterrey- a wavy profile with rounded edges, imitates classic tiles.
• Modern- a variety of Monterrey with more angular, pronounced edges. But still, the similarity with traditional tiles is obvious.
• Cascade– the edges are very pronounced, in general, the material strongly resembles a chocolate bar. The clarity of the geometric shape greatly facilitates the laying of the MCH. The height and width of the wave can be different, which increases the choice.
• Joker- wavy profile with rounded outlines. It differs from Monterrey in wave height.
• Banga- a very curious material with pronounced convex shapes resembling bamboo stalks. visual effect emphasized by the height of the wave. Banga has a smaller width, which somewhat complicates the installation, but it is very effective on small buildings where traditional options do not look good.
• Andalusia- variant with hidden fastening. The shape resembles a wide, gentle wave, designed for laying on a large area.
• Shanghai- MCH with smoothly rounded edges and a clear geometric shape. The latter is emphasized by longitudinal symmetrical lines.

Texture metal tile, incl. green, red, brown and others are discussed below.

Texture

MCH coating can provide not only color, but also a different texture, such models look more original.

• Glossy surface considered classic, given the materials used in the manufacture - aluminum, steel. Gloss not only causes the shine of the roof, but also reflects UV radiation, which negatively affects the color fastness. Lack of gloss - all scratches and scuffs are very noticeable, and it will take effort to eliminate them.
• Matte coating more resistant to mechanical damage, it is easier to repair defects here. However, such material also burns out faster, especially if dark shades were used.
• relief drawing- embossing, imitation of leather, wood grain, ripples, strokes, etc. Best of all, the structural pattern is held on a material such as plastisol.
• PVDF provides another interesting solution- Gloss with a metallic effect. This combination of color and brilliance is very original.
• Rough specific surface provides coverage that includes quartz sand. This option creates excellent sound insulation and reproduces old tiles.

Metal tile colors

Today, manufacturing companies offer about 50 shades. They are classified according to the RAL catalog. The latter includes 213 shades, and the list includes both luminescent and mother-of-pearl.

This video will tell you more about the colors of metal tiles:

We will talk further about whether the metal tile has GOST.

GOST

There is no special document regulating. To check the compliance of the material with building standards, the following documents are used.

• GOST 14918-90 - regulates chemical and physical properties galvanized steel (which is used for metal tiles), most often used in the manufacture of MCH.
• GOST 24045-94 - this document describes the requirements for bent sheet profiles.
• GOST 23118-78 - indicates specifications metal structures.

Other documents regulating the quality of the polymer coating, copper sheet are also important, if, for example, the MP is made of copper, and so on.

The metal tile not only possesses excellent user qualities, but also magnificent decorative. An extensive range of colors, a variety of profiles, classic and unusual texture - an incomplete list of its advantages.
