Traffic barricades come in types one and two, which indicates how many rails each barricade has. Regardless of type, however, each traffic barricade is a combination of wood and steel. First, the frame of each barricade consists of a galvanized steel frame and the striped portion is plywood coated in latex before having engineer-grade stripes applied. For additional attention, a light can be attached to the top of most traffic barricades. Similarly, A-frame barricades are offered in our store, and these are generally lightweight structures that can be used as a barrier around a construction or roadwork site.
