Polyester metal tile: technical specifications

Polyester metal tiles are often used during roofing. Its prevalence and recognition are due to a fairly low price, which allows you to purchase this type of coverage even with a limited budget of the consumer.

Any metal tile is based on a metal sheet, usually consisting of steel. Its thickness is about half a centimeter. But the process of operation and appearance are mainly influenced by the type and quality of the protective coating, which should protect the material from rust and corrosive processes, as well as temperature changes and adverse weather conditions.

Polyester metal tiles have a special coating. It withstands rainfall and other aggressive environments quite firmly and helps preserve color. In addition, it provides aesthetics of the appearance of the building. Polyester has a wide range of colors, which helps to easily find the desired shade.

Polyester is one of the most popular coatings. Almost all plants specializing in the production of metal types of roof are engaged in the production of such products.

The thickness of the protective layer is small and depends on the type of finish.

1. Glossy or standard tile. Coating products contains polyester, thickness - from 25 to 28 microns. Not bad transfers the external atmospheric phenomena, but is capricious to mechanical influences.
2. Matte finish - is based on a significant proportion of Teflon (polytetrafluoroethylene), which increases the protective properties. This makes it possible to use the coating in almost all climatic zones of Russia. Thickness - from 30 to 35 microns.
3. Textured - has a little more strength and does not change its color under the influence of UV, even if its composition is identical to the glossy counterpart.
4. Double application - a coating with polyester protection on both sides using Twin Color technology increases the life of the metal tile. Usually the color of the front and seamy side match.

Since polyester products are quite delicate, a lot of attention is paid to the manufacturer’s warranty, which depends on the technical equipment of the company and the price group that they are oriented to during manufacture.

Budget models often have a guarantee of no more than one year.But some enterprises that carry out multi-stage quality control and use innovative technologies take responsibility for 5 and even 10 years. These manufacturers include the Grand Line and OMI.

For products of the average price group, the quantitative content of zinc is important - from 120 to 275 g / m2, which increases strength and resistance to damage. Of great importance is its uniform distribution over the surface. In some cases, batches have microcracks or layer breaks, which significantly reduce the quality, and hence the service life of the tiles.

The term of responsibility in this group is on average from 3 to 10 years.

The reliable segment manufacturers producing products with a maximum zinc content include:

• "Unicum" - thickness of a layer of 25 mm, a guarantee - 15 years;
• PE Matt (matte polyester) - 35 mm, warranty - 25 years.

The line of luxury products is represented by high-quality sheets, most often painted with a polymer composition on both sides according to the principle of Twin Color. The cost of such a roof, taking into account the construction of the rafters and auxiliary elements, is on average higher by 5-10% of similar products of the economy class and middle segment.

Average warranty - from 10 to 12 years. 20 years give marks:

• Velur - for smooth tiles with a protective layer of 35 mm;
• Safari - for matte textured, with a coating thickness of 30 mm.

The range of works for which such materials are used can be quite wide. Most often, polyester metal tile is used for roofing on country houses and in low-rise buildings. Due to its versatility is perfect for facades.

Polyester metal tiles are not well able to withstand aggressive mechanical stress. However, with proper transportation, installation and operation, it can last a long time.

When transporting sheets, they need to be securely fastened so that during the trip they will not break or deform. If the climatic conditions of the area in which the material will be used presupposes mainly sunny weather, experts recommend the use of matte or textured polyester due to their higher resistance to ultraviolet radiation.

It is not recommended to apply the coating on objects located in close proximity to industrial enterprises producing emissions of active substances into the atmosphere.

Feature and indisputable advantage of polyester tiles is that the coating can be re-applied. In addition, it should be noted that polyester does not withstand the effects of alkalis, acids and some other chemical compounds, so you need to carefully approach the choice of paint and its composition, if this material is recommended for use in the repair.

Polyester coating varieties are in great demand in the market and are excellent for repair and construction work, and receive positive feedback.
