Abstract (en)

Road safety devices comprising a crash barrier made up of metal profiles 1 which are assembled end to end and which form a continuous surface parallel to the road. The inner flank 1i of the profiles has a convex surface 7 exposed to impacts and this surface carries a solid or pasty slippery coating 8 consisting, for example, of a layer of polytetrafluoroethylene or of a solid silicone resin or of a paraffin-based wax or of micronised graphite or of a layer of grease or of a paint containing particles of graphite or of molybdenum sulphide or of ballotini, of ceramic or of plastic material. <IMAGE>
