Metal tile may be the best covering when building or renovating a house. Consumers are attracted by the beautiful appearance, ease of installation and maintenance.
What is a metal tile
This is a roofing material that uses pre-painted thin sheet steel. Instead of steel, copper or aluminum can be used. They are not as strong as steel, but are not susceptible to corrosion, as a result of which they can last up to 100 years. Depending on the material from which the metal tile is made, the price can vary greatly. The finished sheet is profiled (bent). Sheets are obtained that, when laid, resemble ceramic tiles.
In the early 1980s, the world heard about a new roofing material from Rannila. The novelty was liked by the consumer and quickly gained a reliable position in the world market. It attracts with its appearance, durability, ease of installation and maintenance. It was called a metal tile.
The metal tile sheet consists of several layers:
- protective-decorative (front);
- steel sheet;
- paint (inside).
A protective and then a decorative polymer coating is applied to the metal sheet, which also performs protective functions. Rolled thickness 0.35-0.6 mm. If it is thinner, then the tile is easily deformed and the roof will turn out to be of poor quality. The thicker the roll, the heavier your roof will be. And the more expensive it is. It is recommended to use tiles with a thickness of 0.45 mm for the roof of the house. It is very difficult to distinguish it in appearance from a similar product with a thickness of 0.5 mm. This is sometimes used by unscrupulous sellers, passing off cheaper metal tiles as expensive ones.
The steel coating should, in addition to polymer, consist of a passivating (protecting against internal rust) layer and a primer.
Its absence will lead to the rapid destruction of the polymer coating, and the tile will begin to rust, which means it will rot. You can check the presence of a primer on a sample that the seller should give you.
Zinc, a mixture of zinc with aluminum, aluminum with silicon can serve as a protective metal coating.
Protective and decorative coating
Polymer coatings are more commonly used:
- polyester (glossy);
- matt Pural (polyurethane);
- coarse-grained Purall Matt;
- matte Purex;
One of the best Finnish metal tiles from Ruukki is considered. She started her business in 1960. First, it provided jobs 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 product quality. It cares not only about the technical characteristics of its products, but also about environmental friendliness.
Ruukki metal tile:
- Roofing made of "Monterey" metal tile. Has a small profile wave. Price 475-690 rubles. per sheet depending on the type ("Standard", "Plus", "Premium Plus").
- The Decoray tile looks great. This novelty is a high-quality metal tile. The price for it is relatively small - about 320 rubles. for 1 sq.m.
- Modular metal tile "Ruukki Finera" - a new direction in the manufacture of roofing materials. The price is about 600 rubles. per sheet.
It cannot be said that tiles do not fade at all. This happens over time, but high-quality metal tiles burn out evenly and unnoticed by others. Poor quality is stained. This process is less noticeable on dark tiles. Coatings are durable, do not react to temperature changes. They can normally be used at differences from -50 to +50 degrees. But in the presence of aggressive climatic or natural influences, any tile needs reinforcement during installation.
Characteristics of different coatings
Thicknessprotective and decorative coating is selected depending on the environment of product use. If the room to be covered is located 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 hazardous production nearby, a denser coating is needed. Maximum thickness 200 µm.
Finnish metal tile has a guarantee not only for the technical condition, but also for external characteristics. A metal tile coated with "polystyrene" has a 10-year warranty on appearance and 30 years on technical condition.
Purex coated products are even more reliable. They have a modern look. Aesthetic warranty 15 years, corrosion and damage protection 40 years.
Finnish "pural" metal tile (matte finish) is made 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 done by cold pressure method. All processes are fully automated. The wave-like appearance of the rolled sheet is given by profiling rollers. Then a transverse wave is created, also using cold stamping.
The size of the wave (height and distance between two waves) can be different, depending on the type of metal tile. Depending on these parameters, different rules are applied according to which the metal tile is installed. The product manual must contain thisinformation.
There is a small Finnish metal tile, with one tile. But it is more difficult to produce and even more difficult to mount. Therefore, preference is given to a profiled sheet (as slate sheets once replaced ceramic tiles).
Metal tile advantages
- Light (5-10 times lighter than ceramic).
- Easy to install.
- Low maintenance.
- You can choose different colors and textures (matte, coarse).
- Cheap installation.
- Can be laid in winter.
- Not covered in moss.
- Can be laid over old flooring by adding a new crate. This is very convenient when renovating a house, when it is possible to flood the ceiling with rain.
Disadvantages of metal tiles
- It makes a lot of noise when it rains, so it is better to use soundproof materials during installation.
- The roof gets very hot, therefore, along with noise insulation, heat protection is also laid.
- All holes made must be insulated with paint to prevent corrosion.
- It is necessary to use high-quality seals for self-tapping screws, otherwise the roof will leak over time.
- When repairing roofs of complex shape, material consumption increases greatly.
- Requires a special tool for mounting.
The main disadvantage of this roofing material is wind and rain noise. But is the metal tile to blame? The noise is often associatedwith improper roof installation.
This happens if:
- roof crate uneven;
- insufficient number of self-tapping screws, poor quality seals on them;
- small tilt angle;
- wrong insulation and soundproofing.
Metal tile care
It's easy. Leaves, dust do not get stuck on the roof due to the properties of the coating. They slide on the roof and roll down. The drainage system is also easily cleared of fallen leaves.
Buyers confirm the quality of Finnish metal tiles. They note that after five, and sometimes even ten years, her appearance has not changed.
Consumers love that metal roofs don't need to be repaired.
I like the fact that the tiles have a bend of the lower edge. This prevents the bottom sheet from chafing and makes the seam invisible.
The only minus is the high price of the product.
Finnish metal tile is of high quality. Therefore, manufacturers are not afraid to indicate the name of the manufacturer on their products. On the reverse side of each sheet put information about the company and the main characteristics. This allows you to verify the authenticity of the product. Therefore, if you took the word of the seller that the product purchased from him without identification marks is the Finnish metal tile, blame yourself.
