SAND 20 is one of the most versatile corrugated sheets of the whole range. The multicorrugated section with a narrow interaxis makes this profile walkable and particularly resistant, as well as self-centering* in the case of half-round roofing. The reduced height of the corrugated profile makes this product ideal for the realization of over-coverings where it is important to limit the height of the covering package.
When used in the wall, for the realization of a ventilated facade, the particular shape of the trapezoidal fret gives a marked and at the same time elegant aspect.
