Steel roofs

The industrially fabricated profile roofs
from steel and aluminium sheet can be
economically used as single sheet roofs
without rear ventilation, as a spaceen-
closing element and weather protection,
also known as cold roofs. These are, for
example, canopies, covered open spaces
and storage halls not requiring
thermal insulation.

The much greater market share, however,
is taken by profile roofs from steel sheet
in the field of warm roofs.
