Depending on the structural system chosen, the layout of our drop ceiling is either:

Hiding the entire roof structure (typical V2B system).

Hiding purlins only (typical Portifort system and other systems to 2-water).

In the first case it requires the installation of a special structure suspended from the roof rafters, while in the second type, fixation was done directly under purlins. Unless stated we consider the drop ceiling of each structure.

Among the various materials available, include:

-Undulated aluminum.
-Prelaquered steel sheeting.
