Metal Monterrey, technical specifications 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, is made from a polymer coating, tile wave parameters (step and maximum height) and more.

What is the metal Monterrey (Monterrey)

This metal with such a great title, in general, is a classic.That is, it follows the shape of the most traditional ceramic tiles.Well, inside her - strong galvanized steel, reinforced polymer layer.This material is often used when you need to restore the roof of a historical building, renovated appearance places receive very similar to the way they were in the historical past.However

, for devices roofs of modern houses with tile profile Monterrey is good and is in great demand.

structure sheet metal

metal sheet consists of several layers.As seen in the photograph, to protect the steel surface is coated on both sides.Each layer of the sheet metal is designed to carry a specific function and is responsible for the quality of all products.

The structure of the sheet metal

  • inner layer - a thin sheet of galvanized steel.Thanks to him roofing can withstand considerable loads.
  • on each side of the sheet metal covered with a layer of zinc or alyumotsinkovym.This reduces the likelihood of corrosion.
  • next layer, also located on both sides - primer with high adhesion.He needs to paint a firmer hold on the metal.
  • On the front side of the sheet is applied to the polymer layer.This layer improves durability, protecting tiles from adverse conditions.
  • Inside there is a layer of lacquer, which also contributes to the protection coating.

Specifications metal Monterey

From which consists of layers of sheet metal we have considered, now let's talk about what has or specifications should fucked each layer, so that the product was high quality and could last for a long time.

thickness of the metal sheet

how to define Standard, this value for metal sheeting and should be in the range of 0.4 to 0.6 millimeters.Type of steel: roll, cold-rolling.The sheets are formed on a special roll forming equipment.With the exception of thickness fluctuations over the entire surface of the steel sheet.

for metal Monterrey this thickness is generally - from 0.4 to 0.5 millimeters.According to GOST deviations can be up to 0.05 millimeters.In Europe, much stricter requirements - the ISO thickness deviation of not more than 0.01 millimeter.These parameters give the finished product a good rigidity and sufficient strength.

protective polymer coating applied

this coating before the tile sheets will be given waveform.The layer of polymer gives a lot of positive qualities of the future roofing.

  • creates a barrier to corrosion, as well as ultraviolet light.
  • surface much less destroyed mechanically.
  • long tile does not lose its color.
  • summer heat and winter cold is not dangerous.

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

1. Polyester - coating thickness of 25 microns, consisting of resistant polyester paint.She is very well protected against corrosion and mechanical damage.


2. Matte Polyester - coating thickness of 35 microns, a refined look and a special resistance to weather fluctuations.Suitable for any climate.

Matte Polyester

3. plastisol - coated with polyvinyl chloride (PVC).Its thickness - 200 microns.It gives excellent protection against ultraviolet rays, corrosion and damage (both mechanical and chemical).


4. Pyral - coating of polyurethane, or pura (thickness 50 microns) is well tolerated large jumps in temperature.Its color is very resistant, corrosion protection - almost one hundred percent.


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

dimensions and types of profiles Monterrey

great importance when choosing the size of the sheet metal are Monterrey, as well as the type of profile.To choose the most appropriate type of profile, it is possible to reduce costs and the number of cut pieces.The savings are obvious.First of all it is necessary to take into account the following parameters shingles:

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

All these figures differ slightly, depending on the type of profile of Monterrey.

Species Profile Monterrey, there are three:

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

MP Monterrey
width of the sheet nominal mm Sheet width useful mm Leaf length, mm Height mm Step wave mm Metal thickness, mm
1180 1100 0,5 - 9 39 350 0,4 - 0,5

2. MP Supermonterrey - some variationprevious type.It has a large height profile.This roofing material looks very dignified and respectable, it is most similar to the real ceramic tile.

MP Supermonterrey
width of the sheet nominal mm Sheet width useful mm Leaf length, m Height mm Step wave mm Metal thickness, mm
1180 1100 0,5 - 9 46 350 0,4 - 0,5

3. MP Maxi - (MetalMonterrey Maxi) has increased the width and height of the waves.In this form it are particularly expressive.They emphasize the architecture of the building, giving it a completeness.

MP Maxi
width of the sheet nominal mm Sheet width useful mm Leaf length, mm Height mm Step wave mm Metal thickness, mm
1180 1100 0,5 - 9 46 400 0,4 - 0,5

About coloring of metal Monterrey

color table RAL, inventedat the beginning of the last century in Germany, it has a very broad spectrum.Considered in this paper metal painted it in accordance with this table.Therefore colors shine of metal Monterrey variety and richness of colors.This allows you to build himself a roof of a color what your heart desires.It should be emphasized that this certainly meets all the international quality standards.

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

First the good

  • This roofing material is sufficiently hard, it has a high resistance to stress.
  • water is not able to seep through metal roofing Monterrey.
  • Ultraviolet rays do not penetrate the protective layer of the polymer.
  • Temperature fluctuations do not harm metal tile - it will not burst from the cold and does not lose its shape from the heat.
  • corrosion have virtually no chance to penetrate the layers of polymer varnish and galvanizing, reaching the metal.
  • service life of this metal is very durable - it can lie intact on the roof of up to 30-50 years.

In addition, sheets of metal Monterrey weigh very little.Therefore, its load on the rafters is small - only 3.5 to 5.5 kg.So there is no need to apply a system of reinforced rafters.This saves materials and finances, and time.

And at Monterrey metal tiles do not need frequent crate.Thus, the type of profile MP Monterrey has a profile step 35 centimeters.Accordingly, exactly the same, and will move crates.Again, clearly visible to substantial savings construction materials - in fact at their rare crate requires significantly less.

Now the drawbacks

In general, much less minuses than pluses.There are only two.

  • Unfortunately, this complex metal tile roof cover is not very profitable.Too much waste remains.But flat rectangular roof can be covered with a minimum of residues.
  • Well, the noise should be said - he accompanies all roofing metal products.If you do not make a good sound insulation, and the howling wind and patter of rain and hail will be clearly audible in the room.However, you can kill two birds with and applying roof heat insulator with good sound dampening properties.
