It has already been 7 years since I covered the roof with the remarkable Bang metal tile from Insi. I want to immediately say the quality is simple - excellent !!! If you initially correctly install the metal tile, then the joints will not be visible at all. The production was carried out completely in Russia, which makes it even more pleasant, pride is manifested that we began to make quality products. The quality is really excellent, many companies will be given a head start, for the entire time it is installed, the paint has not even faded in any place, like brand new. There is no rust, no shoals, and all thanks to the polymer that covers the metal in several layers.
P.S. Until now, scraps from her are lying in the garage, they used to lie under the fence, and, if they were there, believe me more than one winter, snow, water, etc. And on them even small traces of rust are not visible!
