CLOSED SURFACE TILES Excel closed surface tiles employ the patented Shock Pocket surface, which deadens shock and increases compression, a must for workers that are required to stand in static positions for extended periods of time. The Excel surface has pronounced ridges, giving it a greater co efficient of friction. Excel tiles have been designed with FlexLock™, the patented interlocking system that ensures stability, even in extreme conditions. OPEN SURFACE TILES Excel open surface is ideally suited for applications within the food industry. Excel open has exceptional drainage capabilities and the compression columns on the underside of the tile have been sealed to increase hygiene standards. In order to maintain sanitary conditions, the FlexLock™ Interlocking System allows the Excel line of tiles to be rolled up without coming apart, for ease of cleaning underneath.
