What exactly are traffic barriers? Well they are a couple different things, depending on the type of traffic barrier. There are concrete barriers, plastic barriers filled with sand or water, and other types of barriers. Plastic barriers are usually recyclable and stack able as well.
Traffic barriers are used to guide vehicles or pedestrians, or to block access to certain areas. Compared to other traffic control products they command the respect of drivers more because of how they look. Make sure the traffic barriers you purchase are stack able, because a lot of money can be saved in transportation costs.
