Corrugated sheet particularly suited to the construction of new roofing (minimum slope: 7%) in industrial and civil buildings. On curved roofs, starting from a radius ≥ 16ml, these sheets can be self-centered during laying (maximum sheet thickness: 7/10mm). Considering that this material is very light, Metaplak corrugated aluminum sheet is recommended for laying over old roofing. The geometry of the H28 profile enables its use in roofings with long flashings and shallow slope, thus offering adequate ventilation.

DETAIL OF OVERLAP
When a large surface is to be covered, using sheets of greater width, where the constant side overlap is approximately one and a half corrugations, offers noteworthy advantages in terms of the cost of overlapping and this means that fewer sheets need to be installed and secured, a great savings in time. A drainage gutter created on the top of the corrugation, next to the sheet overlap, offers further guarantees against water infiltration.
