Metal tile monterrey

The metal tile with such sonorous name belongs to the section of classics. It most closely resembles the shape of ceramic tiles. Each sheet of metal is made of durable steel, which is protected by a special polymer layer. Monterrey is often used for roofing buildings belonging to the historical heritage. However, such flooring is ideal for residential buildings. In this article we will tell you about why Monterrey metal tiles are in great demand. What makes this material so popular? The whole secret lies in its special technical characteristics.

Benefits

• The Monterrey profile is ideally combined with different types of wall decorations. It is applicable to cover the roof of both stone houses and wooden.
• Creeps on the roof of any form. The only restriction is the slope angle of 14 °.
• Easy to install.
• The maximum operating period is 50 years.
• There is no need to construct a reinforced roof system. The weight of Monterrey tiles is on average 5 kg / m².
• If necessary, you can quickly and easily repair the roof.
• Environmentally friendly product.
• Does not sustain combustion and is resistant to fire.
• Excellent data on external indicators. There is a wide range of textures and colors. The coating is resistant to sunlight and does not fade.
• Resistant to temperature changes and exposure to air.

Structure of the sheet

Monterrey sheet metal consists of several layers. Special polymer coating is available on both sides of the sheet. At the same time, each layer of the sheet is responsible for one or another function:

• The inner layer is a thin sheet of galvanized steel. It is he who takes on the main load from the outside.
• On both sides of the profile there is an alumina zinc or galvanized layer. It prevents metal corrosion.
• Similarly, there is a primer layer on both sides, which is characterized by high adhesion. Thanks to him, the paint is much better kept on the surface of the metal.
• Only on the front side there is a polymer layer. The durability of the metal will depend on its quality.
• A varnish coat is applied from the inside, which provides additional protection.

Sheet thickness

According to GOST, the thickness of the Monterrey metal tile profile can fluctuate around 0.4–0.6 mm. Steel for its manufacture is used rolled cold rolling. The formation of each sheet is carried out on the profile-bending equipment. Thickness variation over the whole sheet area is not allowed. Perfect accuracy must be respected. According to GOST, a thickness deviation of up to 0.05 mm is allowed. If we talk about the European standard, here the quality requirements are much tougher. According to the ISO standard, the deviation is acceptable, but not more than 0.01 mm. The result is a product with perfect rigidity and strength.

Based on this, enterprises that produce Monterrey metal tiles have high requirements. If the equipment is not updated, sooner or later, the machines begin to roll sheets with different thicknesses over the sheet area. As a result, metal, having a greater thickness, will put a heavy load on the rafters. The average weight of Monterrey metal tiles, manufactured according to GOST, is 4.5–5 kg per 1 m².

Polymer coating

Polymer coating наносится на лист непосредственно перед приданием формы. Будущее покрытие, имеющее полимерный слой, обладает большим количеством преимуществ:

• It creates excellent protection against UV rays and corrosion.
• There is less mechanical damage to the surface.
• Color fastness
• Not afraid of winter frost and summer heat.

It should be noted that the polymer coating is made on the basis of different polymers. Consider the five most popular ones:

1. Polyester. The coating consists of a resistant polyester paint, 25 microns thick. Creates perfect protection against corrosion and possible mechanical damage.
2. Matte polyester. The coating thickness is 35 microns. Differs in a refined look and good resistance to temperature differences. Can be installed in different climates.
3. Plastizol. The coating is made of PVC, 200 microns thick. Protects against chemical and mechanical damage, corrosion and ultraviolet rays.
4. Pural The coating thickness is 50 microns and consists of polyurethane. Quietly transfers sharp temperature fluctuations. Corrosion protection equals 100%.
5. PVDF. The mixture of polyvinyl fluoride and acrylic is 27 microns thick. The color of the coating does not fade from sunlight, and does not break under loads.

So, to summarize, the following technical characteristics of the Monterrey metal tile depend on the quality of the polymer coating:

• цветостойкость,
• resistance to mechanical damage
• chemical resistance
• operational life,
• anticorrosivity
• UV resistance
• endurance to temperature changes.

Geometry of sizes and profile types

The key role is played by the sizes of sheets and profile type. For example, due to correctly selected sheet sizes, it is possible to significantly reduce the number of cut pieces. Therefore, the selection takes into account the following characteristics:

• length,
• width,
• wave step
• profile height.

Depending on the type of Monterrey profile, each of these indicators may differ. There are three types of profile:

1. MP Monterrey. Является самым распространенным и популярным видом кровли. Отличается экономичностью, долговечностью и прочностью.
2. MP Supermoterrey. It is a prototype of the first type. It features a higher profile height. Appearance solid and decent for any building. In appearance it is very close to natural tile.
3. MP Maxi. Differs in the increased height and width of waves. Due to this, its shape looks especially expressive.

For comparison, take the first two types of metal Monterrey.

MP Monterrey

• Sheet width 1180 mm.
• Useful width of sheet 1100 mm.
• Length 0.5–9 m.
• Profile height of 39 mm.
• Wave step 3.5 cm.

MP SuperMotor

• Sheet width 1180 mm.
• Useful width of sheet 1100 mm.
• Length 0.5–9 m.
• 46 mm high profile.
• Wave step 3.5 cm.

As you can see, the technical characteristics of the geometry and type of profile are almost identical.

Production

For the manufacture of metal Monterrey, you must have equipment that is fully automated. As mentioned at the beginning of this article, the main raw material is steel. First, it undergoes passivation. This process consists of applying a protective zinc layer that will prevent oxidation. After that, the surface is primed. It is important for good adhesion of the future polymer layer to steel. When all protective layers have been applied, the sheets are shaped into the desired shape using a profiling method. Through the use of high-tech lines it turns out to achieve high accuracy and stability of the rolled products and, as a result, the output of high-quality products.

All phases of work must meet technical requirements. Otherwise, the products will not meet the standards of Monterrey metal tiles.

Note! Remarkable is the fact that ISO certificate requirements are much stricter than GOST.

Rules of transportation and selection

Having dealt with all the technical characteristics of this type of metal tile, it is important to pay attention to its method of transportation and selection. As for the first, it is important to observe the following requirements:

• For unloading / loading it is important to use the gangway. This will ensure a smooth movement of the profile packs.
• For transportation it is necessary to use only the transport whose trunk corresponds to the length of the sheets.
• It is allowed to carry metal tile only in a vertical position in order to prevent sagging.
• Storage is only possible under a canopy in a dry place. For storage, it is necessary to build a podium or lay a timber, 200 mm high.

As for the choice, it is important to take into account all the technical characteristics in the complex, which we discussed with you in this article. Only in this way it will be possible to acquire a truly high-quality product that will comply with all existing standards.
