PROENTRANCE MATT SLIM SYSTEM is an entrance mat with raw aluminium structure glued on a polyethylene terephthalate (PET) mat. It constitutes a real barrier to cleaning: it ensures optimal protection and the permanence of soils subjected to intense traffic: pedestrians, supermarket trolleys and shopping centers. Lightweight, easy to handle and easy to maintain, it is installed on the back or in a recessed position, inside or outside under shelter (as an entrance airlock).
