USE
Corrugated sheet particularly suited to the construction of new roofing (minimum slope: 7%) in industrial and civil buildings and for renovation of old, rotten roofing.
On curved roofs, starting from a radius ≥ 8ml, 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. With its geometry, the H20 profile can be used in buildings with short flashings, vertical lining and/or cladding, buildings located in areas with little rainfall or on roofs that require special or frequent maintenance.

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.
