Long Fatigue Life Modular Prefabricated Steel Bridges Delta Bridge is a temporary or semi-permanent large-span assembled highway steel bridge, which can be erected with a span of 36 ~ 81 meters. The bridge truss is 4.5 meters high and the unit section is 2.25 meters long. It can be used as a permanent bridge for concrete decks or as a semi-permanent bridge for steel decks.
Long Fatigue Life Modular Prefabricated Steel Bridges Delta Bridge is a through down bridge composed of upper chords, lower chords, triangular webs, beams, bridge panels and connectors. The connection between components is bolted. External or built sidewalks can be designed on both sides of the bridge.
Long service life, large carrying capacity and good overall appearance; the modules can be completely interchanged, and assembly is simple.
