Polymeric coatings of metal tiles
Coated metal tiles - pural, polyester, plastisol, etc. Characteristics and manufacturers, current prices for polymer coatings of metal tiles.
In the production of corrugated board and metal tiles, a steel sheet with a protective polymer coating is used. Coatings vary in thickness and characteristics and significantly affect the price of the finished material.
Sheet structure:
- protective and decorative polymer coating,
- primer (both sides),
- passivating layer (on both sides),
- zinc layer (on both sides),
- steel sheet,
- protective paint.
A properly applied coating will protect a sheet of metal from rust for decades. At the same time, the bright color of the roof will be preserved.
Types of polymer coatings
Polyester is the most inexpensive option for polymer-coated metal tiles. This protective coating is made on the basis of polyester.
The main advantage of polyester metal tile is that it perfectly withstands adverse climatic influences - temperature extremes, rains, hail, heating up to +90 and frosts down to -60 ° C. Suitable for all climate zones. Color fastness is good.
The thickness of the polyester layer is 25 - 27 microns. Therefore, it is not as resistant to mechanical damage as plastisol. It requires careful handling during installation and delivery. Coated with polyester, both Finnish metal tiles, and Swedish, and Russian ones are produced.
Matte polyester
Matte polyester - a coating based on polyester enamel with the addition of metal particles. Thickness of a layer of opaque polyester on a metal tile - 35 microns. This coating has all the advantages of ordinary polyester, but the matte metal tile looks nobler on the roof and does not shine in the sun.
In addition, the resistance to mechanical damage of matte polyester is slightly higher than that of ordinary polyester due to its greater thickness (35 microns instead of 25-27 microns) and a more durable surface layer.
With a matte polyester coating, we offer metal tiles from Sweden Mera System.
Prelaq Nova is a modern protective coating. Produced by a large Swedish concern SSAB. Thickness 50 microns.
The properties are similar to polyurethane-coated metal tiles - it also tolerates climate influences and not very careful handling during installation. But the Nova coating does not contain polyurethane.
Top Coat 50, P50 and HBP (High Build Poliester) are the old names for Prelaq Nova metal roofing.
Metal tile Prisma (Prism)
The protective and decorative coating Colorcoat Prizma ® was created by the Anglo-Dutch metallurgical concern Corus. Coating thickness 50 µm. Corrosion resistance is 2 times higher than that of polyester.
Prism metal tile is one of the most interesting roofing options. Several original colors with a metallic effect make it unique.
Pural (Pural™)
Pural ®* is a polymer coating based on polyamide-modified polyurethane. The coating is designed and manufactured by Rautaruukki.
Metal tile Pural (Pural ®) has a silky-matte surface with a slight sheen.
Its resistance to “weather impacts” is better than that of polyester metal tiles. The coating withstands heating up to +100°C and cooling down to -60°C. Resistance to mechanical damage is higher due to the greater thickness compared to polyester - 50 microns.
Matte Pural (Pural Matt ™)
It is also a product of the Rautaruukki concern. The main characteristics are similar to Pural ® metal tiles.
Only the appearance differs - such a roof does not shine at all in the sun. Outwardly, its surface is similar to ceramic tiles, and to the touch it resembles Teflon.
Plastisol
Plastisol is the thickest coating with a thickness of 200 microns. It resists scratches better than any other. It consists of polyvinyl chloride (base) and plasticizers. Outwardly, it is distinguished by a pattern on the surface - strokes, dotted recesses, "shagreen leather".
Resistance of a metal tile plastisol to corrosion high. In the conditions of a modern city with its polluted aggressive atmosphere - a very valuable quality.
But in terms of resistance to ultraviolet radiation and elevated temperature, plastisol is inferior to other coatings. Heating above 60 ° C is undesirable for him. Such a roof cannot be installed in the southern regions. Plastisol metal tile, price:
HPS 200 is a coating similar to plastisol metal tiles. Produced by the Anglo-Dutch metallurgical concern Corus. The resistance of HPS 200 to corrosion is higher due to the presence of zinc alloy (95%) and aluminum (5%) on the surface of the steel.
This is a new development of the Arcelor Mittal concern. Thanks to a special technology, Cloudy metal tiles have a matte smoky surface - as if it were natural fired clay tiles.
Any other coating is one-color. Moreover, the appearance of the Cloudy metal tile coating is such that from a distance of about 2 meters it is difficult to distinguish it from natural clay! By the way, translated from English Cloudy means "cloudy".
The thickness of such a cloud cover is 35 microns. According to the characteristics, it approximately corresponds to the purala.
Metal tile Printech
Printech Terracotta Burn metal tiles are produced from DONGBU STEEL metal, a South Korean steel manufacturer, one of the largest in the world.
