Bridge Girder Profiles

FRP bridge girders are heavy pultruded sections used as primary load-carrying beams in composite bridges. They provide a corrosion-free alternative to steel or prestressed concrete girders. Arvind Composites cites pultruding bridge deck sections up to 50 kg/m, indicating the capability for large girders. FRP bridge beams are especially valuable in saline or de-icing salt environments, where steel would quickly corrode.
