Monterrey metal, the technical characteristics of which will be discussed in this article, is the most popular roofing material. Its most important parameters are the exact dimensions of the sheet, and its thickness, which polymer the coating is made of, the parameters of the tile wave (pitch and maximum height) and much more.

Metal Monterey Specifications

What is a Monterrey metal tile?

This metal tile with such a resounding name is, in general, a classic. That is, it repeats the shape of traditional ceramic tiles as much as possible. Well, and inside she has a durable galvanized steel, reinforced with a layer of polymer. This material is often used when it is necessary to restore the roof of a historical building, repaired places get a look very similar to what they were in the historical past. However, for the installation of the roof of modern houses, a tile with a Monterrey profile is well suited and is in great demand.

The structure of the sheet metal

Sheet metal consists of several layers. As can be seen in the photo, there is a coating on both sides to protect the steel surface. Each layer of a sheet of metal tile is designed to carry a certain function, responsible for the quality of the entire product.

The structure of the sheet metal

  • The inner layer is a thin sheet of galvanized steel. Thanks to him, the roofing can withstand significant loads.
  • On each side, the sheet of metal is coated with a galvanized or aluminum-zinc layer. This reduces the likelihood of corrosion.
  • The next layer, also located on both sides, is a soil with high adhesive ability. It is needed so that the paint holds on to the metal more tightly.
  • A polymer layer is applied on the front side of the sheet. This layer increases durability, protecting a tile from adverse conditions.
  • Inside there is a varnish layer, which also contributes to the protection of the coating.

Technical characteristics of a metal tile Monterey

What layers the metal tile sheet consists of, we have examined, now we’ll talk about what technical characteristics each layer has or should have so that the product is of high quality and can last a long time.

Sheet metal thickness

As defined by GOST, this value for metal and corrugated board should lie in the range from 0.4 to 0.6 millimeters. Type of steel: coiled, cold rolled. Sheets are formed on special roll forming equipment. In this case, thickness fluctuations over the entire surface of the steel sheet are not allowed.

For Monterrey metal tiles, this thickness is usually from 0.4 to 0.5 millimeters. According to GOST, deviations can be up to 0.05 mm. In Europe, the requirements are much more stringent - according to the ISO standard, the deviation in thickness is not more than 0.01 mm. Such parameters give the finished product good stiffness and sufficient strength.

Protective polymer coating

This coating is applied before the tiles are given a wavy shape. The polymer layer gives a lot of positive qualities to the future roofing.

  • A barrier is created for corrosion, as well as for ultraviolet radiation.
  • The surface is much less mechanically destroyed.
  • The tile does not lose its color for a long time.
  • Summer heat and winter cold are not dangerous.

A polymer coating can be made based on one of the five most common polymers:

1. Polyester - a coating with a thickness of 25 microns consisting of resistant polyester paint. It protects against corrosion and mechanical damage very well.

Polyester

2. Matte Polyester - a coating with a thickness of 35 microns, distinguishes an exquisite appearance and special resistance to weather fluctuations. Suitable for any climate.

Matte Polyester

3. Plastisol - coating of polyvinyl chloride (PVC). Its thickness is 200 microns. It provides excellent protection against ultraviolet rays, corrosion and damage (both mechanical and chemical).

Plastisol

4. Pural - a coating of polyurethane, or pural (thickness 50 microns) perfectly tolerates large temperature jumps. Its color is very resistant, corrosion protection is almost one hundred percent.

Pural

5. PVDF - a coating thickness of 27 microns is made from a mixture of acrylic with polyvinyl fluoride. It does not fade from sunlight, does not break under mechanical stress and can serve an extremely long time.

Geometrical sizes and types of profiles Monterrey

Of great importance when choosing are the dimensions of the Monterrey metal tile, as well as the type of profile. By choosing the most suitable type of profile, you can reduce costs, as well as the number of pieces cut. Savings are evident. First of all, the following parameters of the tile should be considered:

  • Length;
  • width
  • profile height;
  • wave step.

All these indicators differ slightly and depend on the type of Monterrey profile.

There are three types of Monterrey profile:

1. MP Monterrey - This is perhaps the most popular type of roof. It is strong, durable and very economical.

2. MP Supermonterrey - a certain variation of the previous type. She has a large profile height. This roofing material looks very dignified and solid, it most of all resembles a real ceramic tile.

3. MP Maxi - (Metal Monterrey Maxi) has an increased width and height of the waves. Due to this, its forms are particularly expressive. They emphasize the architecture of buildings, giving them completeness.

About the coloring of the metal Monterrey

The RAL color chart, invented at the beginning of the last century in Germany, has a very wide range. The metal tile considered in this article is painted in accordance with this table. Therefore, the color scheme of Monterrey metal shines with variety and richness of shades. This allows you to build a roof of the color that your soul desires. It should be emphasized that at the same time all international quality standards are always respected.

About a barrel of honey and a fly in the ointment (pros and cons of metal)

First about good

  • This roofing material is quite solid, it has a high resistance to stress.
  • Water is not able to leak through the Monterrey metal tile.
  • Ultraviolet rays do not penetrate the protective layer of the polymer.
  • Fluctuations in temperature do not harm the metal tile - it does not burst from frost and does not lose its appearance from the heat.
  • Corrosion has practically no chance to penetrate through the layers of polymer, varnish and galvanizing, reaching the metal.
  • The life of this metal tile is very long - it can lie on the roof without changes up to 30-50 years.

In addition, sheets of metal Monterrey weigh very little. Therefore, its load on the rafters is small - only from 3.5 to 5.5 kilograms. So there is no need to use a system of reinforced rafters. This will save materials, and finance, and time.

And under the Monterrey metal tile, you do not need a frequent crate. So, the type of profile MP Monterrey has a profile pitch of 35 centimeters. Accordingly, the step of the crate will be exactly the same. Once again, significant savings in building materials are clearly visible - after all, with a rare crate, they require significantly less.

Now about the flaws

In general, there are much fewer minuses than pluses. There are only two of them.

  • Unfortunately, it is not very profitable to cover a complex roof with this metal tile. Already a lot of waste remains. But a flat rectangular roof can be covered with a minimum of residue.
  • Well, it should be said about noise - because it accompanies all roofing metal products. If you do not make good sound insulation, then the howling of the wind, and the sound of rain with hail will be clearly audible in the room. However, you can kill two birds with one stone by applying a heat insulator with good soundproofing properties to the roof.
