What can be cooked from squid: quick and tasty

Monterey is visually similar to natural tiles familiar to many. Therefore, it can be used both for large-scale construction works, and a small repair of the existing roof.

When choosing this material as a future roof covering, you should be aware of its several main characteristics. In particular, the Monterrey metal tile, the technical characteristics of which consists of several parameters: dimensions, profile thickness, wave step, etc., also has several types of polymer coatings and profile varieties.

Metal tile production

A standard sheet of metal tile is made using several layers. First the inner layer is a galvanized steel sheet. This allows the material to be strong enough and withstand impressive loads. The sheet is rather thin, since steel with a thickness of 0.35-0.52 mm is used in production.

The fabricated steel mold is then coated with a layer containing a certain amount of zinc to prevent the occurrence and progression of corrosion. A special primer is applied to these two layers on both sides, which ensures reliable adhesion. paints and varnishes with a metal surface.

Then use polymer coating of several types, which we will consider later - one from the outside, and paint and varnish from the inside of the profile. They are both designed to protect the roof from external negative environmental influences.

Considering the standard sizes of Monterrey metal tiles, it is worth noting that, according to state standards, the thickness of the sheets varies within 0.5 mm. This is quite enough for the building material to obtain high levels of reliability and strength, experts say.

Types of polymer coatings for metal tiles

Monterrey, specifications which is supposed to have high strength, as well as resistance to external influences, can have several polymer coatings. They differ in thickness, rust resistance of sheets, and other protective properties.

Typically, the following types of polymers are used in production: polyester, plain or matte, plastisol, pural, PVDF. The first two protective coatings protect the tiles from corrosion, thereby increasing their service life. The difference matte polyester in a higher thickness - 35 microns. Plastisol with a thickness of 200 microns is excellent for protecting Monterey from direct exposure to direct ultraviolet rays, as well as from mechanical and chemical factors.

In places with a sharply changeable climate, it is better to use tiles with a polymer coating made of plural. It allows the roofing not to lose its working appearance and technical characteristics at high temperature drops. The layer thickness is about 50 microns.

And finally, PVDC or polyvinyl chloride with a thickness of 27 microns. Thanks to its manufacture with the use of acrylic, it significantly extends the use of the tiles, reliably protecting the sheets from various kinds of damage.

How to intelligently choose the right size for Monterrey shingles?

The metal tile is well suited for covering roofs of a flat classical shape. If you choose it for use in a more complex design, you can face the costly use of the material, since a considerable part of the sheets after trimming will turn into a heap of waste. To save money, experts advise you to select the most suitable sheet sizes directly for your structure. In this case, one should take into account such characteristics of Monterrey as width, length, wave pitch, wave height, etc.

The most popular and often used in construction types of Monterrey metal tile profiles:

• MP Monterrey,
• MP Supermonterrey,
• MP Maxi.

The first type of profile, with a sheet length of 0.5-9 mm and a height of 39 mm, is most often chosen by builders. It provides good performance for shingles, is durable and resistant to external influences.

Supermonterrey has similar characteristics. However, the profile height is an order of magnitude higher and reaches 46 mm. This type of profile is more expensive, while its high cost is more than compensated for by worthy aesthetic qualities, presentable appearance. In both cases, the pitch of the profile wave varies within 350 mm.

The largest step can be obtained when choosing the last type of profile - Maxi. In this case, it will be 400 mm. Maxi's standard length is 0.5-9mm and width is 46mm. Often, MP Maxi is used in the construction of buildings with a unique architectural solution, in which this type of metal tile looks the most presentable. In general, the useful width of each of the profiles is 1.1 m, while the total varies within 1.19 m.

Advantages and disadvantages

The tangible advantages of the tiles in question include, first of all, its quality, durability and aesthetically attractive appearance. Using Monterrey, you can bring the appearance of the roof as close as possible to that covered with an expensive natural ceramic tiles.

The building material is strong enough to withstand significant loads. At the same time, it has a small mass, fluctuating within 4-5 kg, which does not exert an unbearable load on the building structure.

Metal tiles can be used in almost any area with a wide variety of climatic conditions. The roof covering can withstand both extreme heat and very low temperatures.

Special protective coatings protect Monterrey from corrosion and extend its service life up to 40 and even 50 years.

A wide range of tile colors allows you to choose the most suitable option for any building. Popular shades of Monterrey include ruby ​​red, wine red, ivory, light gray, green, white, and many others.

However, like any construction material, metal tile has a number of limitations:

• the need to install noise insulation. Falling precipitation or strong winds cannot but be reflected by a whole symphony of sounds on the metal surface of the roof. Therefore, the future owner of the roof, when choosing Monterrey, should think over the installation of sound insulation in advance;
• increased costs when laying a complex roof. The combined design will require the masters to adjust the sheets to the parameters of the roof, which will inevitably lead to the appearance of a large amount of waste;
• limitation in the minimum roof slope. Experts believe that the best option Masonry metal tiles will be a roof with a slope starting at 14 degrees.

Today, metal tiles are most widely used among roofing materials. Externally, it repeats the shape of traditional tiles. It is made of profiled, thin-sheet steel with a protective polymer coating. The most popular type is the Monterrey metal tile, technical characteristics, advantages and installation are discussed in detail in this article.

This type of metal tile is the most demanded. It is based on cold rolled sheet steel with the addition of aluminum and copper, which provides it with high strength. From above, the material is covered with a protective anti-corrosion and polymer layers. They provide resistance to external influences (rain, snow, hail). The Monterrey profile has up to 50 shades, which allows you to implement various solutions and combine with any facade design.

The material can only be used for roofs with a slope of at least 14-15 °. Otherwise, snow will linger on it and increase exposure to strong winds and direct sunlight.

The structure of the sheet of metal

The photo shows that the sheet of metal tile has several layers. They cover the steel base on both sides and provide the product with the required properties. Each coating layer has its own function.

1. The inner layer is a sheet of profiled steel with a thickness of up to 0.6 mm, which provides the ability roofing withstand loads.
2. The protective galvanized layer covers the metal sheet on both sides and protects it from corrosion.
3. The third layer is a primer applied on both sides. Serves as an additional anti-corrosion protection and provides high adhesion of paint on a metal surface.
4. Polymer layer - applied to the front side, protects against weather conditions, increases the durability of the roofing.
5. The inner side of the product is covered with a layer of varnish, which serves as an additional protection.

The metal tile MP Monterrey is a metal tile of the classic version, which is actively used for roofing buildings for various purposes and for the reconstruction of historical buildings. The peculiarity of the Monterrey metal tile lies in the geometry of the profile, which is close to the shape of a natural clay tile.

Advantages of metal tiles Monterrey

In addition to the aesthetic requirements, the Monterrey metal tile produced by Metal Profile allows you to meet the financial expectations of all categories of buyers, because the range includes series with polyester coating, plastisol, Colorcoat Prisma ™ and other materials.

Wide color palette that includes both traditional shades and new colors, different kinds surfaces (matte, glossy, "metallic", etc.) allow you to find the most suitable option for any architectural solution.

Installation is carried out with an overlap and requires the use of a batten, a sealant and special roofing screws, which are supplied in the kit.

Metal Profile products are presented in sheets of various sizes and types, you can purchase metal tiles directly FROM THE WAREHOUSE by choosing the nearest office of the Company or a dealer in your region.
You can specify the size of the metal tile in the office when ordering. Production capabilities allow us to manufacture metal tiles of any length (up to 8 m) for non-standard roofing. Recommended sheet length - up to 4.0 m for easy transportation, storage and installation of metal tiles.

If necessary, a protective film can be applied to the metal tile during manufacture (removed immediately after installation). The Agneta coating is coated by default. Metal tiles from the Metal Profile Company must be marked.

There is a possibility of ordering metal tiles with applied anti-condensation coating.

Features and Benefits

Moderate profile height (15 mm) is a key feature of the Monterrey metal tile. It has practically no restrictions in use, but it provides certain advantages in comparison with materials from other lines in the following cases:

• large roof of a compact building - a low profile helps to focus attention on the building itself, and the roof does not look overly bulky;
• objects of classical architecture (construction and reconstruction) - the relief of Monterrey is as similar as possible to the appearance of natural tiles, and modern material with the right color, it does not discord with classic facades.

The versatility of the Monterrey metal tile also lies in the ability of the material to be different depending on the chosen color scheme... Calm tones - and the gaze itself begins to assess the shape of the roof. Bright colors, shine, play of texture - and the roof becomes a single art object. Fortunately, the choice of decors is truly great.

What is metal roofing? It is a sheet roofing material made of galvanized steel that closely mimics ordinary tiles. The metal-tiled roof looks elegant and impressive, while the installation is carried out with minimal effort and financial costs. Due to these features, the material is very popular in Europe, Russia and the CIS countries.

However, the range of metal tiles is quite diverse, so it can be difficult to choose the optimal type of roof. Consider the main characteristics and requirements for this material in order to know how to choose it correctly.

What's inside? The composition and structure of the roofing sheet

The metal tile has a multilayer structure. A sheet of metal made using cold rolled technology is usually taken as a base. Then the finished profile is subjected to step processing. In particular:

A layer of phosphate is applied to prevent corrosion.

Priming is carried out in order to increase the adhesion of the finished metal.

A polymer coating of various colors is applied to the front surface.

The back of the sheet is treated with a protective varnish.

As a result, metal tiles have the same composition, regardless of the manufacturer, however, the characteristics of the roof and the quality may vary.

What are the metal shingles. Available varieties of roofing material

Profile types

All metal tiles on the market differ in the type of profile, which gives the roof a unique pattern. In Russian construction market the following options are in high demand:

Monterrey

It is a rigid profile that closely imitates ceramic tiles. This type of profile is characterized by a length 1 100 mm, 6 waves with step 350 mm... The profiling height can increase or decrease, affecting the rigidity of the structure. The use of such metal tiles gives the building a classic look of modern architecture.

"Cascade"

It is characterized by strict geometry and rectangular shapes. If you order metal tiles of this profile in brown, the roof will resemble a chocolate bar. The width of such sheets is 1 120 mm, structure - 5 waves on 224 mm, step height: 22.5 mm... The advantages of the profile are the minimum number of joints, which saves material. Due to its strict shapes, the profile is suitable for residential and commercial buildings.

"Joker"

The profile of the metal tile resembles the popular Monterrey, with a more "lush" geometry. With standard sheet sizes, the wave height is 49 mm, accordingly, in conditions of low-rise construction, a roof from such a profile will look more attractive.

"Athena"

Quite an original profile, where a wave-like structure alternates with a flat base. Such a metal tile organically fits into any architectural style, therefore, it is often used for the reconstruction of buildings.

In addition to the usual varieties of metal tiles, new models with original patterns appear on the market. For example: "Bongo", "Andalusia", "Shanghai". The sheets attract attention with a relief pattern (wave height up to 66 mm) and Z-shaped lock connections, which allows installation without the use of external fasteners.

Base materials for sheet metal tiles

The types of metal tiles on the market usually differ in the type of profile. However, this is not the only distinguishing feature. For manufacturing, a different basis is used, which largely determines the characteristics of the roof. For example:

Steel... This is the most common type of metal tile on the domestic market. The base material is usually coated with a layer of zinc to increase the durability of the roof and its resistance to corrosion.

Aluminum... This profile is less common, but it has a number of undeniable advantages. In particular, aluminum is neutral to any external influences, therefore, it does not need additional processing. In addition, the material is quite light, which reduces the load on the foundation and supporting structures; installation does not require a solid lathing. The disadvantages of aluminum metal tiles include a very meager palette of colors and high cost.

Copper... This is initially an expensive material that is rarely used in private construction. Copper metal tiles look imposing and pretentious, especially when covered with a greenish coating. The material does not require additional protection against corrosion, however, it is mainly used for the reconstruction of architectural monuments and antiquities.

It is worth noting that the most common and practical is galvanized steel tile, which we will consider in the future.

Pros and cons to keep in mind

Like any building material, metal tiles have their own advantages and disadvantages. TO strengths roofs include such moments:

Durability. Without losing its properties and technical characteristics, a metal roof can last more 50 years.

Resistant to temperature extremes. The range of application varies within -50 / + 70 degrees, which ensures the possibility of application in any region of the country.

Diversity. Despite the identical manufacturing technology, the material boasts various shapes and colors.

High strength. The width of the sheet minimizes the number of joint seams. In addition, the sheets are usually overlapped, which significantly increases the tightness of the roof.

Ease of installation. Metal tiles can be laid on the old roof, which significantly increases the speed of work. For example, a team of specialists can assemble about 100 m2.

Essential disadvantages the following applies:

Restriction to the angles of inclination of the roof. In order for the metal tile to fully cope with its tasks, the slope angle must exceed 14 degrees.

Not suitable for complex roof geometries. During installation, you will have to adjust the wave and pattern, which increases the amount of production waste - up to 30% of the total.

Relief structure. The undulating structure of the leaf can prevent the natural rolling of snow from the roof.

Low sound insulation. To solve the problem, you have to lay an additional layer of insulation.

Specifications

It should be noted that the metal tile is manufactured in accordance with the current GOST standards. For this roofing material the following technical parameters are characteristic:

Tensile strength - 300-490 MPa.

• .

Lifetime - 20-50 years old, depending on the thickness and type of polymer coating.

Frost resistance - average indicators: 200 cycles freezing.

Fire safety - steel does not burn, the melting point is 1,500 degrees.

Environmental safety - the profile material and polymer coating are non-toxic, therefore they do not pose a threat to health and life.

It is worth noting that metal tiles tend to accumulate static electricity, therefore, for such a roof, the installation of a lightning rod is a prerequisite.

Table of characteristics depending on the type of coating

Roofing sheet dimensions

In the manufacture of metal tiles, manufacturers try to adhere to standard sizes... It looks like this:

Width: 1 160-1 180 mm.

Length: 0.5-9 m.

Thickness: 0.4-0.6 mm.

Wave step: 350 mm.

Profile height varies within 39-46 mm, depending on the manufacturer. It is necessary to clarify that the width of the sheet is divided into actual and useful, both parameters are indicated on the package. Considering that the sheets are overlapped, the usable width is usually 1 100 mm.

Table with the main dimensions of some manufacturers

Weight of metal tiles for 1m 2

This parameter is usually indicated on the packaging and directly depends on the thickness and size of the sheet. Weight values ​​may vary depending on the material used. For example:

Cink Steel - 3.8 kg.

Aluminum - 1.34-1.36 kg.

Copper - 4.45 kg.

The data is relevant for standard sizes with sheet thickness 0.5 mm... Weight is based on 1 m2... It is worth clarifying that the height of the profile and the thickness of the polymer coating can affect the weight of a sheet of metal tile.

What's better? Brief comparative analysis

There are several types of roofing materials on the construction market, so buyers are often worried about the question: "Which type to give preference to?" Consider a comparison of metal tiles with the most competitive types of roofing.

Metal tile or corrugated board

These are very similar materials made of galvanized steel with a polymer coating, but differing in technical characteristics. In particular:

Thickness. Decking looks more solid: 1.2 mm against 0.6 for metal tiles at maximum values.

The weight. The thickness of the material increases its weight, therefore, a more solid base is required for the installation of corrugated board.

Appearance... The metal tile looks more textured, so the roof of this material looks much more interesting.

In terms of sound insulation and durability, both materials are identical, but corrugated board wins in terms of price. Therefore, if reliability and simplicity are important, it is undoubtedly better to use corrugated board, beautiful design roofs and exquisite design - uniquely metal tiles.

Metal tile or Ondulin

Ondulin is soft roof, which is manufactured using a single technology and has standard sizes regardless of the manufacturer.

Ondulin is much lighter than metal tiles, which simplifies the installation process. However, the metal tile looks stronger, does not burn, but loses in terms of sound insulation. It is worth noting that ondulin is more expensive and cannot boast of a varied color palette. Therefore, when choosing a roofing material for a private house, preference should be given to metal tiles, if we are talking about a small structure (bathhouse, garage, veranda), it is better to use ondulin.

Metal tile or Slate

The first option undoubtedly wins here. The metal tile does not require a strong crate, is resistant to direct exposure to ultraviolet radiation, and is not afraid of moisture. However, slate has better sound insulation and attracts buyers at an affordable price.

How to calculate the amount of material on the roof

Calculations can be made independently without resorting to complex mathematical formulas... To do this, you need to calculate the length of the ridge and roof slopes. Consider the calculation of the roof for a typical house with gable roof where the length of the skate is 9.5 m, stingrays - 6 m... The following formula applies here:

We divide the length of the ridge by the useful width of the sheet ( 1.1 m). The result is 8.6 sheets... The resulting value is rounded to an integer and we get 9 sheets.

The length of the slope is calculated by the step of the wave. Regardless of the manufacturer, this value is always 350 mm... As a result, to cover one side you will need 17.14 waves.

Standard sheets are characterized by a structure in 10, 6, 3 and 1 wave. Therefore, the amount of material is determined based on these features.

Colors available to the consumer

The available colors depend on the specific manufacturer and, as a rule, the choice is in the range: from 5-10 options to 50 different colors and their shades. For the manager to understand you correctly, remember the code the desired color according to the RAL table.

Popular RAL variants

At the end of the article there are photos of what the material looks like directly on the roof.

Additional elements for pitched roofs

To increase the tightness and reliability of the roof, additional elements will be required. For metal tiles, the following products are used:

Cover strips.

Roof eaves.

Decoration for the ridge part of the roof.

Elements for inner corners.

Wind bars.

Adjacent strips.

Passage nodes.

In addition, elements can be installed to increase the safety of the roof: fences, stairs, walkways. Further, using convenient diagrams, we will consider the main stages of work.

His Majesty is montage. Please welcome!

Before starting the installation of a metal roof, the device should be completed rafter system and lathing. For rafters, it is enough to use an edged board with a section 150Х50 mm treated with an antiseptic.

First, you should perform work on the installation of all pipes and ventilation ducts, only then proceed with the installation of the roof.

The step of the rafters for metal roofing is taken in 600-900 mm, usually with the device wooden beams overlap, it is equal to the step of these beams.

Lathing. We prepare a wooden base for roofing

The lathing can be made both solid and sparse. Solid is arranged from edged boards, plywood, chipboard sheets. The distance (step) of the lathing is set based on the step of the shear wave.

When constructing lathing from unedged boards it is required to thoroughly get rid of the bark even before antiseptic treatment.

Preliminarily, a vapor barrier material is mounted on the rafters to avoid condensation from entering the surface of the insulation attic space or on a roof insulation (if, of course, a warm roof is used).

We don't need condensation. Laying the vapor barrier

Installation of the cornice strip

At the next stage, the eaves plank is installed together with the gutter hooks. The bar is overlapped 100-150 mm and fastened with self-tapping screws.

How to lift material onto the roof and not damage it

The lifting of the sheets is carried out in the old, and most likely already familiar to many old-fashioned way.

Direction and scheme of laying roofing sheets

Installation direction depending on the type of roof.

Installation of sheets of metal tiles can be done from either side of the building, just take into account the overhang of the material 40-50 mm over the cornice.

When installing a roof made of metal tiles, step on the surface only between waves of material (see the picture above), shoes should be used with soft soles.

How to fix the sheets of metal tiles correctly

The sheets are fastened with special self-tapping screws with gaskets; they can be matched to the color of the sheets.

On 1 sq.m the roof requires at least eight self-tapping screws.

The overlap of the tile sheets is one wave in the horizontal direction, and in the vertical direction, the sheets of material must be matched to the entire length of the roof slope.

At the end of the installation of all sheets, the ridge is installed. There is nothing difficult in this, you can pick up a metal ridge of the desired color for sale. The ridge is fastened with nails or self-tapping screws to the sheathing boards, the ends of the ridge are closed with special plugs.

Mount thoroughly. The service life of a metal tile roof is at least 50 years old!

Which brand is better to give preference to? Verified manufacturers

If we talk about manufacturers, the following brands can be distinguished:

Finnish metal tiles are presented on the Russian market by the company RUUKKI... It is one of the leading European manufacturers offering Monterrey profiles with Purex polymer coating.

GRAND LINE... Russian company engaged in the manufacture of metal tiles in accordance with the latest developments in this area. The lineup represented by Monterrey and Country profiles, coated with Polyester and SOLANO.

MERA SISTEM... A Swedish company that produces galvanized steel sheet metal with a sheet thickness of 0.45 mm. The products of the enterprise are resistant to sudden temperature changes and are produced in various colors.

Of course, there are much more manufacturers of metal tiles, but here are companies that have been working on the Russian market for a long time and have earned the trust of buyers.

So what is metal roofing? Metal tile is a type of profiled sheet made of thin-sheet galvanized steel with a characteristic appearance that imitates natural tiles. Roofing material in Russia and the CIS countries has long become "popular", which is not surprising. At a relatively low price, this roofing material is known for its reliability and, therefore, a long service life.

The main technical characteristics of metal tiles

In this article, we will analyze in detail and in an accessible language the main technical characteristics of metal tiles, find out what you should first pay attention to when buying this roofing material and thanks to what properties the metal roof has become so in demand in the construction market.

Roof slope for metal tiles

Unlike soft and welded roofs, metal tiles should be laid taking into account the minimum permissible angle of the roof slope relative to the horizon. First of all, this technical characteristic is associated with the optimal distribution of wind and snow loads on the roof. Therefore, in the southern regions, you can use metal tiles for flatter roof structures.

It should be added that this rule is relevant for all types of roofs made of sheet metal.

Sizes of sheets of metal

The width of the sheet of metal, depending on the height of the profile, ranges from 1.1 to 1.19 m. The higher the profile, the smaller the width. This is due to the typical size of a flat sheet (1.25 m), from which the metal tile is subsequently profiled.

The width of the metal tile with the "monterrey" profile is 1.18 or 1.19 m, and the useful (working) - 1.1 m

Metal tiles of any profile and shape, as a rule, are cut to fit a given roof size. But you can often find the standard (typical) sheet length metal roof... Its dimensions directly depend on the size of the wave. Sheets are cut in multiples of 1, 3, 6 and 10 waves plus 10-15 cm for subsequent overlap. For example, for the most common profile "Monterrey", which has a wavelength of 0.35m, typical sheets will have a length of 1 wave - 0.5m, 3 waves - 1.18m, 6 waves - 2.25m and 10 waves - 3, 65m. Sizes may vary slightly from those shown above.

Monterrey profile views

For more information on all types of metal tile shapes, see the article. Here we will analyze the most common models of this roof.

Monterrey. In such a profile, the metal tile has a width of 1.19m (useful 1.1m) and a wave step of 0.35m. The roof has a classic attractive appearance. Profile height: 25 + 14mm.

Supermonterrey. It differs from the previous model by the height of the profile, due to which such a metal roof has the maximum resemblance to natural (ceramic) tiles. Profile height: 25 + 21mm.

Maxi. The profile is almost identical to the Supermonterrey shape. The only difference is the longer wave step (0.4m).

The composition of the metal tile

The main point when choosing a metal tile is not how it looks, but what it consists of. Let's consider the composition of the metal tile layer by layer.

Polymer coating. Protects the roof from natural factors and mechanical damage. Further in the article, we will briefly analyze the main ones.

Priming. A gray primer layer provides additional protection against corrosion of the metal.

Zinc. Metal tiles with the highest zinc content usually last much longer than their counterparts. Below we will dwell on this important component of the metal roof.

Steel. At the moment, it is used with a thickness of 0.35mm to 0.52mm.

Protective paint. Not used on all models. You can easily identify metal tiles with an extra coat of paint. Usually the paint is applied in the same color as the roof itself (as opposed to the gray color of the ground).

Polymer coatings

You can read more about the types of polymer coatings in. Here we will analyze the main ones.

Polyester-, perhaps, the most common and vulnerable metal tile coating due to its inexpensive cost. The coating thickness does not exceed 25 microns. Polyester has a glossy, smooth texture. The coating least of all protects the roof from "fading", i.e. loss of factory color.

Polyurethane. In contrast to polyester, one can cite as an example the most resistant coating for thin sheet roofing. A polyurethane coating (known as "pural") will best protect the material from natural weathering and UV radiation.

Zinc amount

Along with the polymer coating, the amount of zinc in the roof is the most important technical characteristic of metal tiles. This indicator is the main protection against corrosion. Without sufficient zinc in the steel sheet, all other constituents are simply irrelevant.

The zinc content is measured in g / m². As a rule, in inexpensive options for metal roofing, this figure does not exceed 100 g / m². For greater savings, such products are produced with a thickness of 0.4 or 0.45 mm (OH). The normal content is considered to be a zinc layer of the 2nd class (140 g / m² and above). Such metal tiles include, for example, Norman (produced by Metal Profile) or the roof from Grand Line in polyester coating. In polyurethane-coated metal roofs, the zinc content can reach 275 g / m² and higher.

Tile thickness

Thin sheet steel materials range in thickness from 0.33 to 0.9mm. Metal tiles, in turn, are limited to a range of 0.4-0.52mm. The thickness of the sheet is an important technical characteristic that affects the ability of the roof to withstand mechanical loads without changing its shape and tightness. It is especially scrupulous to approach the choice of a metal roof in the central and northern regions, where the snow load often affects the roof structure. Tiles can be conventionally divided into 3 classes according to their thickness:

• Economy. More often produced with a thickness of 0.4 mm, there are low-quality materials with a thickness of 0.33 mm;
• Standard. This class includes metal tiles OH ( general purpose) with a thickness of about 0.45mm;
• Premium. Metal tiles with a sheet thickness of 0.5 mm and above.

It is best to choose a metal tile for a roof with a thickness of 0.5 mm!

In the central region of Russia, premium segment products should be installed on the roof. This will protect the roof from mechanical damage and the effects of atmospheric phenomena (ice, snow, hail, etc.).

Metal tile weight

This technical characteristic is important, first of all, for the transportation of the roof, as well as for its installation. The weight of a metal tile may vary slightly depending on its shape and thickness. It is generally accepted that the average value of the mass of metal tiles is 4 kg / m² and 5 kg / m² for sheet thicknesses of 0.4 and 0.5 mm, respectively.

Warranty for metal tiles and their service life

Immediately, we note that the "guarantee" and the real "service life" of course should differ in favor of the latter. But theory does not always work in practice.

Typically optimal warranty obligation on the roof of the "premium" series, 15-25 years should be considered (not 50 or 60). During this period, you can easily prove the origin of this material by the factory marking indicated on it in the lock part of the metal tile, which indicates the manufacturer, name and series (or date) of production.

You should only buy labeled products!

In accordance with the above characteristics (polymer coating, amount of zinc and metal thickness), manufacturing organizations assign a warranty period for metal tiles, during which they are obliged to change the material to a similar one.

For metal tiles of an economy class, the manufacturer's warranty often does not exceed 3 years. For example, metal tile monterrey with a thickness of 0.4 mm from the Metal Profile plant has a warranty of only 1 year. For the "standard" class, the terms can be increased up to 10 years (for example, Norman from the Metal Profile plant or GL PE 0.5 from the roof manufacturer Grand Line).

To get acquainted with the process of installing metal tiles, we offer video instructions for installing metal tiles from the Metal Profile plant and advice on the selection and production features of metal roofing from the manufacturer Grand Line.
