Today, roofing materials such as slate and iron are used very rarely, because they require constant care and have many disadvantages. And if earlier it was necessary to cover the roofs with these materials, since there were simply no others, now the situation has completely changed. Currently, one of the most popular materials for roofing has become a metal tile. The material has many important characteristics.
- Exact geometric dimensions.
- Excellent quality.
- Resistant to any external conditions.
- Reliable material protection.
- The presence of a polymer protective coating on both sides of the sheets.
- Long service life.
- Variety of shapes and surface shades.
This is exactly what the roofing products of the "Grand Line" brand are. The metal tile of this company has also shown itself to be a material that is safe for humans and the environment.
Ohmanufacturer
LLC "Grand Line" is a major Russian manufacturer that has been producing products for the construction of sheet steel since 2008. The basis of product quality is the choice 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 metal tiles are produced is Obninsk. The local plant "Metalist", having vast experience in working with metal and the latest equipment, began to produce high-quality products that are in great and constant demand. Cold-rolled galvanized alloy steel is used for manufacturing. Moreover, polymer protection is preliminarily applied to the metal (258 grams per 1 sq / m), after which further processing of the canvases takes place.
Thanks to this, all Grand Line products (metal tiles, siding, corrugated board) are distinguished by unsurpassed elegance and high quality. The main proof of product quality is the fact that the manufacturer issues the longest warranty for metal tiles - 25 years. Among the warranty cards for all similar products, this is an absolute record.
Features of metal tiles
The high quality of the Grand Line metal tile was obtained due to the fact that, unlike similar products from other companies, it consists of several layers. This is:
- Sheet steel.
- Zinc plated.
- Anti-corrosion protection layer.
- Primer coat.
- Colored resin coating.
- Lacquer.
Moreover, sheet steel is the middle of a multilayer complex structure. Zinc coating, protection, primer is applied to both sides of the sheet. But the colored polymer can be applied either on both sides, or only on the outer surface. In the latter case, varnish is applied to the inside of the paintings as a protection.
As protection, different types of polymeric substances can serve, with which the Grand Line metal tile is covered. The price of products is determined by what type of polymer was used for protection, since the performance and durability of the material depend on this.
Plastisol coating
The coating consists of a plasticizer and polyvinyl chloride. Its thickness is 200 microns, which makes the material highly resistant to mechanical damage.
The front surface of sheets with plastisol protection is covered with a pattern. Unfortunately, plastisol is not very resistant to ultraviolet radiation, so the roof loses its original color over time. With a 5-year warranty, products with this coating can last 4-5 times longer. For 1 sq.m. you will need to pay from 570 rubles.
Polyurethane
50 micron protective coating creates a material with excellent resistance to corrosion, UV, damage. This protection is enough for 25-30 years of service. In addition, polyurethane-coated sheets can be mounted even at temperatures below -10 degrees.
In addition to other advantages of Grand Line products,polyurethane-coated metal tiles resist s alt fogs, which are not uncommon on sea coasts. Therefore, this material can be used even for houses built in maritime climate zones.
Guarantee for sheets with polyurethane - from 15 years, and they can serve more than a quarter of a century. Price - from 410 rubles. per sq.m.
Polyester
Polyester is made from polyester, an inexpensive material, so its use does not greatly increase the cost of products.
Benefits:
- Plasticity.
- Anti-corrosion resistance.
- Fade resistant.
- Multiple colors.
- Affordable price.
Unfortunately, canvases are subject to mechanical damage, so they are recommended for the manufacture of roofs in areas where environmental and weather conditions are normal. A guarantee for products with polyester protection from 10 years. The material can last about 15-20 seasons. Cost per 1 sq.m. – from RUB 580
Matte polyester
The thickness of the protection is 35 microns, although this is less than the thickness of the protective layers of other materials, metal tiles:
- Excellent chemical resistance.
- Does not fade.
- High mechanical performance.
- Has anti-corrosion properties.
The manufacturer issues a guarantee for 10 years, but the coating can last more than two decades. Price sq.m. - from 420 rub.
Aluzinc
This kind of coveragehas several components:
- 1.6% silicon;
- 43, 4% zinc;
- 55% aluminium.
The combination of materials that are resistant to corrosion, fire, mechanical damage, endows metal sheets with special properties. Thanks to this, the surface of the canvases cannot be scratched, it is not afraid of hail, moisture, and does not darken over time. But most importantly, no harmful substances are released during operation, including toxic fumes.
Manufacturer's warranty for aluzinc coating is 10 years, and it can last 2.5-3 times longer. Cost - from 750 rubles/sq.m.
Product range
Grand Line is the only brand in Europe that has been able to combine the production of metal tiles with other similar products: metal decking, vinyl siding, metal gutter systems and other types of similar building materials.
Metal siding "Grand Line" is in great demand among consumers. These are sheets of galvanized steel coated with a polymer substance. Due to the fact that metal siding can be easily given any desired shape, it is used for wall cladding and many other surfaces where such properties as durability, ease of installation, and aesthetics are extremely important.
If we compare metal siding "Grand Line" with a vinyl counterpart, the first wins significantly in terms of strength and service life. Although synthetic materials have manyadvantages, they, unlike metal, cannot withstand temperature fluctuations from +80 ° to -55 °. The secret is that the metal has a low coefficient of expansion, so it reacts little to temperature. And thanks to polymer protection, metal siding does not corrode, and therefore it serves a much longer period of time, which is extremely important for each consumer.
The corrugated board produced by the company is usually covered with the same materials as the metal tile. In fact, corrugated board is the same sheets of galvanized steel, but with a different profile. On sale you can find several types of profiles that differ in the width of the ribs. On the ribs themselves there are longitudinal bends, which, in addition to the decorative function, give the canvases the necessary rigidity so that they can withstand wind and temperature loads during operation. The use of corrugated board is quite wide. It is used to make:
- Roofing.
- Fences and barriers.
- Formwork.
- Sheathing of commercial and agricultural buildings.
Metal tiles are of high quality. It, unlike similar products from other companies, consists of several layers.
- Sheet steel.
- Zinc plated.
- Anti-corrosion protection layer.
- Primer coat.
- Colored resin coating.
- Lacquer.
Moreover, sheet steel is the middle of a multilayer complex structure. Both sides of the sheet are zinc coated, protected,primer. But the colored polymer can be applied either on both sides, or only on the outer surface. In the latter case, varnish is applied to the inside of the paintings as a protection.
