High Stability Steel Box Structure Girder Bridge Heavy Load Capacity
Box Girder Bridge is a bridge where the key beams consist of girders shaped like a hollow box. Box girders comprise structural steel, pre-stressed concrete, reinforced concrete or composite of steel. Such girders are used for footbridges, railway bridges and highway bridges. Box girders are mostly used for long span bridges where the actual self weight of the bridges has to keep minimum. They are also used for situations that require high torsional stiffness of box girders.
Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Facts about box girders A box girder comprises two concrete slabs — top and bottom. The slabs are connected by an array of vertical bridge stems, also known as webs. These webs can be vertical or inclined, as per your requirement. Box girders are formed by joining two web plates by a common flange at both the ends. And this makes a closed cell that has enough strength and torsional stiffness than that of an open section. And this is the reason for choosing box girders. Box girders are not generally used for construction of buildings. However, they might be required in certain circumstances like when the loads are carried eccentrically to beam axis.
Advantages of box girders Reduce the requirement for support points Have high strength and torsional stiffness that give greater and better suitability for horizontally curved bridges Ensure enhanced durability Require minimum maintenance of simple protective coatings as these have less exposed surface and only a few edges
