Today, roofing materials such as slate and iron are used very rarely, since they require constant care and have many disadvantages. And if earlier it was necessary to cover the roofs with these materials, since there simply weren’t others, now the situation has completely changed. Currently, one of the most popular materials for roofs has become metal. The material has many important characteristics.
- Precise geometric dimensions.
- Great quality.
- Resistance to any external conditions.
- Reliable material protection.
- The presence of a polymer protective coating on both sides of the sheets.
- Long service life.
- A variety of shapes and shades of the surface.
These are the Grand Line roofing products. The metal tile of this company also proved to be safe for humans and the world around it.
About the manufacturer
Grand Line LLC is a large Russian manufacturer that has been manufacturing products for sheet steel construction since 2008. The basis for 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 metal tiles are produced is Obninsk. The local Metallist plant, having vast experience in working with metal and the latest equipment, began to produce high-quality products that are in great and constant demand. For production, cold-rolled alloy galvanized steel is used. Moreover, the polymer is pre-applied with polymer protection (258 grams per 1 sq / m), after which further processing of the paintings takes place.
Thanks to this, all Grand Line products (metal, siding, corrugated board) are distinguished by unsurpassed elegance and high quality. The main evidence of product quality is the fact that the manufacturer issues the longest guarantee for metal roofing - 25 years. Among the warranty cards for all similar products, this is an absolute record.
Features of metal
The high quality of the Grand Line metal tile was due to the fact that, unlike similar products from other companies, it consists of several layers. It:
- Sheet steel.
- Zinc coating.
- Layer of corrosion protection.
- Primer.
- Color polymer coating.
- Lacquer.
Moreover, sheet steel is the middle of a multilayer complex structure. Zinc coating, protection, primer are applied on both sides of the sheet. But the color 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 canvases as protection.
Different types of polymeric substances with which the Grand Line metal tile is coated can serve as protection. The price of the product is due to the type of polymer used for protection, since the performance and durability of the material depend on it.
Plastisol coating
The coating consists of 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, a pattern is applied to the front surface. 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
A 50 micron thick protective coating creates a material with excellent resistance to corrosion, ultraviolet and damage. This protection is enough for 25-30 years of service. In addition, sheets with a polyurethane coating can be mounted even at temperatures below -10 degrees.
Among other advantages of Grand Line products, polyurethane-coated metal tiles resist salt fogs, which are not uncommon on sea coasts. Therefore, it is possible to apply this material even for houses built in marine climate zones.
The warranty on sheets with polyurethane is 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 of polyester - an inexpensive material, so its use does not greatly increase the cost of the product.
Benefits:
- Plastic.
- Corrosion resistance.
- Resistance to fading.
- Many color schemes.
- Affordable cost.
Unfortunately, the canvases are subject to mechanical damage, therefore it is recommended to use them for the manufacture of roofs in areas where environmental and weather conditions are normal. Warranty on products with polyester protection from 10 years. Material can last about 15-20 seasons. Cost per 1 m / sq. - from 580 rub.
Matte Polyester
The thickness of the protection is 35 microns, although it is less than the thickness of the protective layers of other materials, metal:
- It resists chemical attack.
- Does not fade.
- It features high mechanical characteristics.
- It has anti-corrosion properties.
The manufacturer gives a guarantee for 10 years, but coverage can last more than two decades. Price sq.m. - from 420 rub.
Aluzinc
This type of coating has several components:
- 1.6% silicon;
- 43.4% zinc;
- 55% aluminum.
The combination of materials that are resistant to corrosion, fire, mechanical damage, endows metal sheets with special properties. Due to this, the surface of the paintings cannot be scratched, it is not afraid of hail, moisture, does not darken over time. But most importantly, during operation, no harmful substances are released, including toxic fumes.
The manufacturer's warranty on 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 trademark in Europe that was able to combine the production of metal with other similar products: metal corrugated board, vinyl siding,
metal gutter systems and other types of similar building materials.
The Grand Line metal siding is in great demand among consumers. These are galvanized iron sheets 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 properties such as durability, simple installation, and aesthetics are extremely important.
If we compare the metal siding "Grand Line" with a vinyl analogue, then the first wins significantly in terms of strength and durability. 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 coefficient of expansion, so it does not react much to the temperature indicator. And thanks to the polymer protection, metal siding does not lend itself to corrosion, which is why it serves a much longer period of time, which is extremely important for each consumer.
Professional flooring produced by the company is usually covered with the same materials as metal tile. In fact, corrugated board is the same sheets of galvanized steel, but having 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 webs 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 for the manufacture of:
- Roofing.
- Fences and fences.
- Formwork.
- Covering of buildings for commercial and agricultural purposes.
The metal tile is of high quality. It, unlike similar products of other companies, consists of several layers.
- Sheet steel.
- Zinc coating.
- Layer of corrosion protection.
- Primer.
- Color polymer coating.
- Lacquer.
Moreover, sheet steel is the middle of a multilayer complex structure. Zinc coating, protection, primer are applied on both sides of the sheet. But the color 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 canvases as protection.
