Copper roofing sheet for the top layer of roof covering construction ensures long-term operation without the need for repair or replacement of the roof over an extended time. Roofing copper sheet has higher rates of wear resistance and corrosion resistance. Due to high temperature strength and attractive aesthetic surface copper sheet also provides everything for fireplace areas.
Copper roofing sheet made of copper grades M1R, M1f, M2, M2P, M3 and M3R according to GOST 859−2001. Parameters cold-rolled sheets can be normal or increased accuracy. Thickness is typically: 0.6−0.7 mm. The hot-rolled sheets are manufactured: width of 600 — 3000 mm and a length of 1 — 6 meters. The maximum variation in length in the range of minus 30 mm in width — minus 200 mm. The cold-rolled sheet manufactured soft, semi-solid or solid. The surface must be clean and free of contamination. Surface defects shall not exceed the tolerances in thickness. Valid lubrication technology. Allowed slight discoloration or darkening. In the hot-rolled sheets of prints allowed on the rolls.
Copper sheet — a unique roofing material, with a guarantee of at least 100 years. It is resistant to corrosion, and eventually only covers oxide film. In Europe, preserved houses covered copper roof since the Middle Ages. It is fair to say that modern roofing copper sheets are not designed for a lifetime, because their thickness is 5−10 times less than the medieval. However, current sheets is much easier, much easier installation. And their price is substantially less. The «self-extinguishes» Unlike the iron oxidation process of copper. The destruction of the iron in a moist oxygen atmosphere flowing avalanche. A copper under the action of O 2, N 2, sulfur and water on its surface forms the so-called patina — a solid film, which reliably protects the copper sheet from further destruction. Copper roofing sheet high tech, it is pliable, easily cut, drilled, compared with an iron sheet, it bends easily, which greatly simplifies the work makes it possible to laying the roof on the surface of a complex profile. Roofing brand M1R, M1f, M2P, handled well, can withstand continuous operation under the most adverse conditions, it is not only used for the roof, but also the elements of drainage structures, tide and so.
