The term "metal" refers to a sheet of roofing material made by the method of cold pressure profiles of copper, aluminum or sheet steel, followed by the application of a polymer protective layer. Outwardly, the sheet resembles a masonry made using traditional ceramic tiles.
The size of the metal tile is set by current standards and specifications. It depends on the equipment used for the production and the type of products manufactured. As a rule, the raw materials for the manufacture of these roofing materials are supplied to the enterprise in the form of rolled sheet metal, the thickness of which lies in the range from four tenths to seven tenths of a millimeter. A polymer coating has already been applied to the metal, performing a two-fold task. It protects it and gives an aesthetic appearance, which is facilitated by the wide color gamut of these products.
The size of the metal tile is set in the technological map (wave step, transverse wave height, length and width of finished sheets). This is one of the most important indicators by which it is customary to classify the specified material. According to the type of profile, the metal tile is divided into:
- "Maxi";
- "Elite";
- Monterrey
- "Trapeze";
- Super Monterrey.
The most popular types of profile are the third and fifth. The size of the Monterrey metal tile in the basic version of its manufacture is:
- sheet length - from 2000 mm and above;
- width - 1800 mm;
- thickness - 0.4-0.5 mm;
This roofing material has various types of protective and decorative coatings, the designation of which is given below:
- Pe - made of polyester;
- LKPC - galvanized steel with organic coating;
- C - one-sided coating (D - two-way);
- RAL - color of the applied coating, according to a similar catalog.
Standard sizes of a metal tile "Monterrey":
- sheet (thickness): 0.4-0.5 mm;
- wave (pitch / height), mm - 350/24;
- width (useful / total), mm: - 1100/1800.
The size of the Monterrey metal tile of other types (Maxi, Granite HDX, Velur, Solano 30, Country) differs from the above and accordingly amounts to:
- thickness: (0.4-0.5) mm / 0.5 mm others;
- wave pitch (mm): 400/350/350/350/350;
- wave height (mm): 24/23/23/23/23.
- width (useful / total), mm: (1100/1180) / (1100/1180) / (1100/1180) / (1100/1180) / (1120/1188).
In addition to the parameter called “metal tile size”, the buyer must pay attention to the following characteristics, which can be safely called as determining the quality of the specified roofing material. It:
- Type and class of protective coating.
- Type and class of decorative-protective coating.
- Steel grade used as a base.
These parameters largely determine the area of use of a metal tile of one type or another. The base polymers used in the manufacture of its coatings are polyvinyl chloride, polyurethane, polyvinylidene fluoride. But in their pure form, as a rule, they are not used.
The optimal characteristics of the specified roofing material in such parameters as price, durability, versatility, ease of installation, make it the most attractive type of product from the group of roofing, which are currently on the Russian market.
