Outdoor walk off mats for commercial buildings need to be able to perform under a variety of weather situations. Ideally, outdoor floor mats will dry quickly, be resistant to ultra-violet degradation and knock off as much sand, salt and grit from shoes before it gets tracked into a building. Exterior walk-off mats used outdoors can be recessed into the walk surface or they can rest on top of the walking surface. Whether recessed or not, all entrance matting should present the lowest profile possible to minimize trip and fall hazards. A primary duty of facility and property managers is to provide a safe, effective floor matting system and outdoor entrance mats play an integral part in this system.
