Bridge Parapet Key Benefits Unique parapet units can be made to specific customer requirements, with in- house mould facilities. Very high containment due to the significant mass of concrete, minimising the risk to traffic using a bridge as they are designed to absorb an vehicle impact rather than deflect the vehicle back into the line of traffic.

Steel parapets normal requires painting or pre-treatment with hot-dip galvanizing as they are prone to corrosion and they are normally the cheapest choice for normal containment level of vehicles.
