Metal tile for roofs: production technology, characteristics

by alanews

The metal tile for the roof is modern material, which is distinguished by high strength and mechanical characteristics, as well as a pleasant appearance. In the production of this roofing material, cold -legged steel is used, which is then galvanized under the influence of high temperatures. Thus, the thickness of the leaf on the total area of ​​the roof is homogeneous. This production technology determines that this roofing material is not amenable to corrosion, and is also resistant to temperature changes and other “dangerous” atmospheric phenomena.

After the sheet passes cold rolling, it is galvanized, and then the passivating layer is applied, after it – a layer of soil, and only then the finish coating. The traditional warranty from manufacturers is 30 years, Ruukki metal is a guarantee of 40 years. But the experience showed that in fact such a metal tile for the roof serves 50 years, without requiring regular care and repair work. The most significant factors on which the quality depends, and, accordingly, the service life of this roofing material is the thickness of the galvanized layer, as well as the polymer layer of isolation.

The most commonly used materials for this are polyester (including matte) and plastisol. Polyester on average has a layer thickness of about 25 mKM. It is suitable for operation in almost any climate conditions, and withstands a temperature of 120C, and is also resistant to burning out coloring. But at the same time, it can be damaged both in the process of transportation and during installation. The matte polyeter is more durable, the thickness of the layer of which is up to 35mmkm. At the same time, it is much more resistant to mechanical stress and aggressive environment. The metal tile for the roof with plastisol is used, as a rule, in an aggressive chemical unit, and this material is the most stable for all of the listed. But only he can withstand the maximum +60C, and also weakly tolerates the effects of sunlight.
