ASTM Standardized Structural Steel Bridge Q345 Low Carbon Steel Product Description: Steel structure bridges are convenient to transport, easy and speedy for erection. They are light weighted with high strength and have the advantage of strong tension and compression resistance.Steel structure bridges mainly used as:1. Highway/ramp bridges: Shorten the time of construction2. Long span bridges: For large span bridges like river and sea crossing bridges can only use steel structure.3. Pedestrian bridges: Short erection time, easy to construct.A truss is a triangulated framework of individual elements or members which act primarily in tension or compression. Trusses have been used in a similar way to beams in composite decks, as arches, as cantilevers or as stiffening girders to suspension bridges.Trusses can be dressed up in many ways to modify their appearance. The box style is the preferred choice as it allows easy attachment of fencing or glazing on the sides and/or top.The surface protection can be paint or hot-dip galvanized.Bridge load capacity, width can be designed according to user's requirementsCarry capacity: resist strong wind and earthquake, bears heavy snow |
