Metal tile Finnish. Reviews and Specs

Metal tile can be the best cover when building or repairing a house. Consumers are attracted by the beautiful appearance, ease of installation and care.

What is metal

This material for the roof, in the manufacture of which is used sheet steel with a polymer coating. Instead of steel, copper or aluminum can be used. They are not as strong as steel, but are not susceptible to corrosion, so they can serve up to 100 years. Depending on the material from which the metal tile is made, the price may vary greatly. The finished sheet is profiled (bent). The sheets are obtained, which, when stacked, resemble ceramic tiles.

History of invention

In the early 80-ies of the last century the world heard about the new roofing material from the company Rannila. The novelty was pleasant to the consumer and quickly found reliable positions in the world market. It attracts by its appearance, durability, ease of installation and care. It was called metal tile.

Characteristics

Sheet metal consists of several layers:

• Protective-decorative (facial);
• primer;
• Passivating;
• Zinc;
• steel sheet;
• Paint (from the inside).

On the metal sheet, a protective, and then decorative, polymer coating is applied, which also performs protection functions. The thickness of rolled metal is 0.35-0.6 mm. If it is thinner, then the tile is easily deformed and the roof will turn out to be substandard. The thicker the rolling, the heavier will be your roof. And so it is more expensive. Recommend to use for the roof of the house a tile thickness of 0.45 mm. It is very difficult to distinguish it from a similar product with a thickness of 0.5 mm. This is sometimes used by unscrupulous sellers, issuing cheaper metal for expensive.

The coating of the steel must, in addition to the polymer, consist of a passivating (protecting from internal rust) layer and a primer.

Its absence will lead to a rapid destruction of the polymer coating, and the tile will start to rust, and therefore rot. Check the presence of a primer on a sample that the seller should give you.

Protective metal coating can be zinc, a mixture of zinc with aluminum, aluminum and silicon.

Protective and decorative coating

Polymer coatings are more often used:

• Polyester (glossy);
• Plastisol;
• Matt Pural (polyurethane);
• Coarse-grained matt Purall Matt;
• Matt Purex;
• Polyvinylidene fluoride PVDF.

Ruukki Company

One of the best is Finnish metal roofing from Ruukki. It began its activity in 1960. First, it provided workplaces for its citizens, and in the 80s of the last century it entered the world market. Works in 26 countries of the world. Constantly improves the quality of products. Cares not only about the technical characteristics of the products, but also about the environment.

Ruukki metal tile:

• Roof of metal "Monterey". Has a small wave profile. The price is 475-690 rub. Per sheet depending on the type ("Standard", "Plus", "Premium Plus").
• Tile "Decors" has an excellent view. This novelty is high-quality metal tile. The price for it is relatively small - about 320 rubles. For 1 square meter.
• Modular metal roofing "Ruukki Finera" - a new direction in the manufacture of roofing materials. The price is about 600 rubles. Per sheet.

It can not be said that the shingles do not burn out at all. It happens with time, but high-quality metal tiles burn out evenly and imperceptibly for others. Poor quality is covered with spots. This process is less visible on dark tiles. Coatings are durable, do not react to temperature changes. Can be used normally at drops of -50 to +50 degrees. But if there is an aggressive climatic or natural effect, any tile needs to be strengthened during installation.

Characteristics of different coatings

The thickness of the protective and decorative coating is chosen depending on the environment of application of the product. If the room to be sheltered is in a normal area where there are no aggressive factors, then a thickness of 25-30 microns is used. But when there is a plant with harmful production nearby, a more dense coating is needed. The maximum thickness is 200 μm.

Metal tile Finnish has a guarantee not only for technical condition, but also for external characteristics. Metal tiles with polystyrene coating have a guarantee for appearance 10 years, for technical condition - 30 years.

Even more reliable products with coating "Purex". They have a modern appearance. Guarantee for aesthetic appearance 15 years, for protection from corrosion and damage - 40 years.

Metal tile "poral" Finnish (matte coating) is produced using polyamide and polyurethane. This makes it possible to make it even stronger and more durable. After all, the guarantees for products with this coating are respectively 20 and 50 years.

Profiling is carried out by the method of cold pressure. All processes are fully automated. Wave-shaped form of rolled steel profiled rollers. Then a transverse wave is created, also with the help of cold stamping.

The wave size (height and distance between two waves) can be different, depending on the type of metal. Depending on these parameters, different rules are applied, according to which the metal tile is installed. The product manual must contain this information.

There is a Finnish metal tile in small size, with one roof tile. But it is more difficult to produce and even more difficult to mount. Therefore, preference is given to the profiled sheet (as in due time slate sheets replaced ceramic tiles).

Advantages of metal roofing

• Light (5-10 times lighter than ceramic).
• Durable.
• Beautiful.
• Easy to install.
• It does not require special care.
• You can choose different colors and textures (matte, coarse-grained).
• Eco-friendly.
• Cheap installation.
• Can be laid in the winter.
• Not covered with moss.
• You can lay on the old covering, adding a new crate. It is very convenient when repairing the house, when it is possible to pour the ceiling on the rain.

Disadvantages of tiles made of metal

• During the rain, noisy, so when installing it is better to use soundproof materials.
• The roof is very hot, Therefore, together with insulation from noise, heat protection is also installed.
• All the holes made have to be insulated with paint to avoid corrosion.
• It is necessary to use high-quality seals for self-tapping, otherwise the roof will leak over time.
• When repairing the roofs of complex shapes, the consumption of material is greatly increased.
• A special tool is required for installation.

The main drawback of the roof of this material is considered noise from wind and rain. But is this the fault of the metal tile? Often, noise is associated with improper installation of the roof.

This happens if:

• Crate on the roof uneven;
• Insufficient number of screws, poor quality of gaskets on them;
• Small angle of inclination;
• Improper insulation and sound insulation.

Care for metal tile

It's easy. Leaves, dust do not get stuck on the roof due to the properties of the coating. They glide along the roof and roll down. The drainage system is also easily cleaned of fallen leaves.

Customer Reviews

Buyers confirm the quality of Finnish metal. They note that after five, and sometimes even ten years, the appearance of it has not changed.

Consumers like that metal roofs do not require repair.

I like the fact that the tile has a lower edge bend. It does not allow to wipe the bottom sheet and makes the seam imperceptible.

Only the high price of a product is called a minus.

Metal tile Finnish is of high quality. Therefore, manufacturers are not afraid to indicate the name of their manufacturer on their products. On the back of each sheet, information about the company and the main characteristics are attached. This allows you to verify the authenticity of the goods. Therefore, if you believed on the word to the seller that the product purchased from him without identification marks - this is Finnish metal, blame yourself.
