The corrugated profile of the exterior cladding will meet the mechanical requirements specified in the project and will also guarantee the watertightness of the roof. The interior steel roof decking will meet the mechanical requirements specified in the project. This interior support profile will be installed on a secondary structure, generally composed of metal, concrete or wooden straps, separated between 1.50 and 3 meters. The most suitable profiles for this industrial roofing solution are the INCO 30.4 Roof, INCO 30.5 Roof and INCO 44.4 Roof profiles.

In those rooms where it is necessary to improve acoustic comfort, solutions can be used with the micro-perforated interior support trapezoidal profile, to increase the acoustic absorption of the deck roof. These perforations can be made in the webs of the profile in profiles with a large depth, or throughout its surface in profiles with a reduced depth. Typically, drilling of type R5T8 is used for perforations in the webs and type R3T6 for perforations throughout the surface.

The simple roof must have a minimum slope towards the water evacuation elements greater than that specified in the CTE DB HS Health. Table 2.10 Slopes on inclined roofs. In particular, the minimum slope must be adjusted according to the profile depth of each profile.

For exterior cladding profiles manufactured by Incoperfil, the adapted slope table is as follows:
