Following a rational yet simple separation of the production area (ISO 7) from the raw material preparation and final packaging zone, the client aimed to protect the two entrances from contamination carried by wheels and shoes. The installation of two washable antibacterial decontamination mats proved to be a straightforward and effective choice, offering easy maintenance and cleaning, both manually with a professional squeegee and with a floor scrubber & dryer with discs. Considering the two large production and preparation areas, the coverage of 12 square meters for the two mats is minimal both in visual impact and economic investment.
