Altro Stronghold 30 adhesive-free is a 3mm thick safety flooring designed for use in commercial kitchens. It provides safety underfoot in hard working commercial kitchens where spillages of a wide range of contaminants such as fats, grease, flour, and water are often seen. Like the well-established Altro Stronghold 30 adhered product this adhesive-free version provides all the safety performance, but without the need to be fully adhered to the subfloor. This reduces installation time and quickens return to service.
