Metal tape roof – an excellent choice for use in climatic conditions of Russia. Delivery of metal tiles to St. Petersburg and l. ABOUT. Produced by the grotesque company. Metal tile is a very popular material for modern roofs. The material combines a number of remarkable advantages: durability, low weight, diverse selection of coatings and colors, ease of laying sheets. The basis of the metal tile is a steel sheet with a thickness of 0.4-0.5 mm. The thickness of the steel determines the strength of the metal tile. On both sides, steel is covered with a zinc layer of 140-280 g/m2, protecting steel from corrosion. The zinc layer is covered with a passivating composition and primer. Next, apply a polymer coating. The reliability and durability of a metal -based roof depends on the type of polymer coating and the thickness of zinc. The color of the polymer coating and determines the color of the metal tile. For metal tiles, the following polymer coatings are used: polyester is a fairly common polymer, which is characterized by plasticity, resistance to atmospheric and mechanical influences. Pural is a polyurethane coating with polyamide additives, the coating has a thickness of 50 microns. The advantage of the Pural is the possibility of installing a roof at a temperature of up to 16 ° C. This material is damaged less than polyester, but not quite resistant to deformation. Plazole – material based on polyvinyl chloride and plasticizers. This is one of the most resistant to mechanical influences of polymer coatings, largely due to a large thickness-200 microns. The disadvantage of this polymer can include low resistance to fading. PVDF, PVF2 – polymer, 80% consisting of polyvinylFtoride and 20% consisting of acrylic. For the roof it is made with a thickness of 27 microns. This material is quite resistant to mechanical influences and aggressive environments, but is the most expensive compared to other polymer coatings. Produced with a large color palette and metal shades (metallic).The metal tile in Russia is presented with three main profiles depending on the height of the wave and width of the finished product: a high wave, a classic wave, rectangular races. Depending on the place of profiling and the origin of the raw materials, the types of metal tiles are as follows: 1. Metal tiles profiled in Russia, from Russian raw materials. The advantages of such roofing material include: low price and short delivery time. Cons: a small thickness of the zinc layer, there are disorders of the leaf geometry, a short warranty period (about1 years) 2. Metal tiles profiled in Russia, from foreign raw materials. Pros: relatively low price, short delivery time, good selection of coatings. The disadvantages include the following: it is difficult to determine the brand of the final product, there are disorders of the leaf geometry. 3. Metal tiles profiled in Finland, from foreign raw materials. Pros of this type of material: the thickness of the zinc coating, always the exact geometry of the sheet, a good warranty period (10-15 years). Disadvantages: a long period of delivery of the order.
The quality of the metal tile, the originality of the roof design, the reliability of such a roof always fully justifies the price of this material.
