High density polyethylene event barricades are available through Concord Crowd Control Service, Inc. You can purchase or rent event barricades through our services. The standard color choices of fencing are yellow and white but custom colors are available. The legs are detachable so that if that part is damaged by people or vehicles, instead of having to dispose of the entire barrier, simply replace the legs, and it is as good as new! Our event barricades were designed with the North American climate in mind. Their description says that they have Thermal Resistance of +120 ºF, and are immune to extreme temperature changes, giving them cold resistance as low as -40 º.
