The finishes are made of mahogany, or anodized aluminum for wall panels and ceiling, in stainless steel for floor panels.
In case of decontamination or sterilization needs, can be installed raw surface panels, to be coated with vinyl heat-sealed (normally not supplied).
If required the panels can be manufactured with Class 1 materials.
Panels are fit by screws directly in the wall or on proper wooden beams.
