Metal tiles laying technology: main features

Since the steel sheets of metal tiles have a significant size and low weight, they can in a short time cover the roof, which has simple geometric shapes. At the same time, waste costs will be minimal. Threw tile sheets should be laid, overlapping using screws — self -tapping screws or special nails for this. Screws — self -tapping screws have a special protective coating, which prevents damage to the polymer coating of the material in the places of fastening, as well as the occurrence of corrosion. Nails, in turn, have gaskets in a hat.
