Today, such materials for the roof, as slate andIron is used very rarely, because they require constant care and have many disadvantages. And if earlier it was necessary to cover the roof with these materials, since there were simply no other people, now the situation has completely changed. At present one of the popular materials for roofing has become metal roofing. The material has many important characteristics.
These are the products for the roof of the brand "Grand Line". Metal tile of this company showed itself as safe for the person and the surrounding world material.
LLC "Grand Line" is a major Russianproducer, which produces products for construction of sheet steel since 2008. The basis of product quality is the selection of serious and responsible suppliers of raw materials. These are the largest European and Asian companies: Posco (Korea), Corus (Great Britain), Arcelor (Belgium) and others.
One of the cities where the metal tile is produced- Obninsk. The local factory "Metallist", having a huge experience of working with metal and the latest equipment, has begun to produce high-quality products that are in great demand. For production, cold-rolled alloyed galvanized steel is used. And the metal is preliminarily applied polymer protection (258 grams per 1 sq / m), after which further processing of the cloth.
Thanks to this, all the products of the "Grand Line"(metal tile, siding, corrugated board) are unrivaled elegance and high quality. The main proof of the quality of the products is the fact that the manufacturer issues the longest guarantee for metal tiles - 25 years. Among the warranty cards for all similar products is an absolute record.
Moreover, sheet steel is the middlemultilayer complex structure. On both sides of the sheet is applied zinc coating, protection, priming. But the colored polymer can be applied either to both sides, or only to the outer surface. In the latter case, the varnish is applied to the inside of the cloth as a protection.
As a protection can serve different typespolymeric substances, which covered the metal tile "Grand Line". The price of the product is determined by what kind of polymer was used for protection, since the performance and service life of the material depend on this.
The coating consists of a plasticizer and polyvinyl chloride. Its thickness is 200 microns, due to which the material is characterized by good resistance to mechanical damage.
On sheets with plastisol protection on the frontsurface attached pattern. Unfortunately, plastisol is not resistant to ultraviolet light, so the roof eventually loses its original color. With a warranty of 5 years, products with this coating can serve 4-5 times longer. For 1 sq.m. will need to pay from 570 rubles.
A 50 micron thick coating createsmaterial with excellent resistance to corrosion, ultraviolet, damage. This protection is enough for 25-30 years of service. In addition, sheets with polyurethane coating can be mounted even at temperatures below -10 degrees.
In addition to other advantages of the "Grand Line" products,metal roofing, covered with polyurethane, resists and salt fogs, which are not rare on the sea coasts. Therefore, this material can be used even for houses built in areas of marine climate.
The guarantee for sheets with polyurethane is from 15 years, and they can serve more than a quarter of a century. The price is from 410 rubles. for sq.m.
Unfortunately, the canvases are subject to mechanicaldamage, so they are recommended for use in the manufacture of roofs in areas where environmental and weather conditions are normal. Warranty for products with polyester protection from 10 years. Serving the material can about 15-20 seasons. Cost per 1 m / sq. M. - from 580 rub.
The thickness of protection is 35 microns, although this is less than the thickness of protective layers of other materials, metal tile:
The manufacturer issues a guarantee for 10 years, but can last more than two decades. Price sq.m. - from 420 rubles.
This type of coating has several components:
The combination of materials that are resistant tocorrosion, fire, mechanical damage, gives metal sheets special properties. Due to this, the surface of the canvas can not be scratched, it is not afraid of hail, moisture, does not darken with time. But most importantly, during operation, no harmful substances are released, including poisonous fumes.
The manufacturer's warranty for aluzinc coating is 10 years, and it can last 2.5-3 times longer. The cost is from 750 rubles per square meter.
Special demand is enjoyed by consumersmetal siding "Grand Line". These are linens made of galvanized steel, coated with a polymer substance. Due to the fact that metal siding can easily be given any desired shape, it is used for wall cladding and many other surfaces where such properties as durability, simple installation, aesthetics are extremely important.
If we compare the metal siding "GrandLine "with a vinyl analog, the first one wins significantly in terms of strength and service life. Although synthetic materials have many advantages, they, unlike metal, can not withstand temperature jumps from +80 ° to -55 °. The secret is that metal has a low expansion factor, so it does not react very much to the temperature index, and thanks to the polymer protection, the metal siding can not be corroded, and therefore it serves a much longer period of time, which is extremely important for every consumer.
Metal tile is of high quality. It, unlike similar products of other firms, consists of several layers.
And sheet steel is the middle layercomplex structure. On both sides of the sheet is applied zinc coating, protection, priming. But the colored polymer can be applied either to both sides, or only to the outer surface. In the latter case, the varnish is applied to the inside of the cloth as a protection.
