Types of metal roofing

• Polyester (PE)

The basis of this coating is polyester. The material has long been used in the production of metal tiles, has a glossy appearance and is distinguished by its plasticity and high color stability.

Metal roofing made of polyester, shiny, smooth, relatively inexpensive. It is highly resistant to corrosion and ultraviolet rays, that is, it will not fade for a long time under the sun. However, in thin layers (up to 30 microns), it is damaged by light mechanical influences, for example, when layers of snow come off the roof. Avoid using polyester where weather conditions are unfavorable.

• Matt polyester (PEMA)

Among types of metal roofing matte polyester looks the most attractive. It is polyester with Teflon added to create a matte finish. In addition to resistance to UV rays, it also has increased resistance to mechanical damage due to the increased thickness of the coating (35 microns). Even in difficult meteorological conditions, it will last a long time.

• Pural (PU)

Pural coated metal tile based on polyurethane, the molecules of which are modified with polyamide. The thickness of the coating is 50 µm, which gives it additional mechanical stability. Ultraviolet light and even chemically aggressive substances, such as acids precipitated in areas with polluted air, do not change properties pural coated metal tiles... It serves for a long time without changing color and mechanical resistance in all conditions.

The surface of such a metal tile is silky to the touch and matte in appearance. Due to the properties of pural, a roof with such a coating is easy to handle and install. The temperatures at which it retains its properties are from minus 150 to plus 1200 degrees Celsius.

• Plastisol (PVC)

Plastisol 200 - metal roofing made of polymer 200 microns thick. Differs in volumetric embossing imitating leather or tree bark. It was developed specifically for difficult climatic conditions, including industrial areas with a high level of environmental pollution.

Plastisol 100 has half the thickness and is used mainly indoors. It is also made with a coating on both sides and is used for the manufacture of weirs.

• Polydifluorite (PVDF, PVDF2)

Of all kinds metal roofing it is the most suitable for facade decoration. It consists of a 4: 1 mixture of polyvinyl fluoride and acrylic. Contains high quality pigments for long-lasting UV-resistant shine and color.

The polymer is quite hard, has hydrophobic properties, which allows it to “repel” dirt, while being quite plastic. It can be either matte or glossy.Metal roofing can be as shiny as metal. To do this, it is covered with varnish on top with the addition of a special dye. Resistant to the atmosphere and corrosion.
