Grade “A” mats are designed to combat fatigue while addressing specific issues unique to food production environments. 3’x3’ interlocking tiles have strong connections and are easy to lift and clean. The proprietary Nitrile compound passes NSF test ASTM G21-96 (2002), has GRAS status and is CFIA approved. Grade “A” gets an “A” for specialized food production applications. ‘Positive interlock’ allows the rubber tiles to lock in, while remaining easy enough to ‘unzip’ for reconfiguration.
