Traffic indicator posts - extruded from hollow plastics section covered directly by extruded layer subdivided into repeated colour pattern

Pref. the second layer which is of low impact polypropylene is extruded in sections having alternating colour pattern. The posts are 30 mm thick, have 500 mm long orange-black or white-black alternating colour sections, and are used for indicating where the edge of the road is, in e.g. snow. Posts are produced in a single operative step.
