Suspension bridges
Suspension bridges consist of main towers, cables, girders, and anchorages. Girders come in the truss girder type, which is adopted mainly in the U.S., and the lightweight box girder type, which was developed in the U.K. and applies aerodynamic principles. Suspension bridges are a type of bridge that is generally adopted as a very long bridge with an effective span of about 150 to 2000 meters. JFE Engineering has manufactured and constructed a large number of suspension bridges to date both in Japan and overseas, including the Akashi Kaikyo Bridge, which is the longest suspension bridge in the world (center span: 1991 meters).
