But for all the merits of the massive use of natural tile in our country is hampered by its high cost, significant weight (enhanced load bearing structures), and also a limited number of colors. However, modern producers of artificial roofing was able to solve such problems, the maximum saving resemblance to natural material. The emergence of new products has become a turning point in the development of the roof architecture. Perhaps the most popular roofing material today is metal. Its basis is galvanized steel sheet with thickness of 0,4-0,5 mm, which is first profiled to give the desired surface topography, and then covered with a colored polymer layer.
Sheets are available covering different types, which vary profile shape, wave height, color and type of exterior covering. Modern manufacturing companies are producing metal roofing with a small (50 mm) and large (50-70 mm), wave height, with symmetrical and asymmetrical wave, and even with exclusive pattern. "Successfully selected metal roofing, – says Paul Seliverstov, Manager, (a leading European provider of solutions made of metal for construction and engineering) – in harmony with the color the house and surrounding landscape that ensures the integrity of aesthetic perception. Moreover, modern technologies make it possible to give the metal a number of individual qualities: for example, the effect antiquity as one of our recent developments – a series of Cascade . Simplifies this selection is that the major manufacturers offer a wide range of different reliefs, which allow precise reach virtually any architectural style.
