Polystar’s engineers have developed a unique fiberglass alternative to concrete style curbing for spill containment areas. Stealth Curbs rise to an angled peak at 3” high and are a great low-profile spill containment option for high foot traffic areas. The Box Curb is available in 6″ heights and is ideal for large applications such as building perimeters, as well as small needs such as individual workstations. Stealth Curbing and Box Curbing are modular for fast installation. 90 degree corners and wall-mounting end pieces create a durable system which is ideal for almost any fuel or chemical spill containment need.
