ABSTRACT:
Disclosed herein is a system and method for a seamless curb system suitable for a sanitary environment while providing an energy absorbing structure. The multicellular structure has a substantially uniform cross section. The structure is formed of hi-density, energy absorbing, expanding polypropylene foam, similar to bumper systems used in cars and trucks. An outer shell is disposed over at least a front portion of the structure. The outer shell may be stainless steel or a polyurea/polyaspartic reinforced coating, as examples. The elements are sealed to each other in an end to end relationship adjacent to a wall to form an energy absorbing protective barrier to the wall. At least one anchor is disposed in a slot in the floor of the manufacturing facility to provide support.
