Steel box girder, also called steel box girder, is a common structural form of long-span bridge. It is generally used on Bridges with large spans, and is named because it looks like a box. Steel box girder has a series of advantages, such as high tensile strength, high elastic modulus, high material utilization efficiency, can effectively play the bearing capacity of the steel plate without redundant components. Its structural weight is small, suitable for long-span Bridges, and with the reduction of the weight of the upper structure, the cost of the lower structure of the bridge will also be reduced. In addition, the production of steel box girder factory is separated from the on-site installation, reducing the number of on-site connections, easy to ensure quality, high reliability, and fast and convenient construction. Steel box girder also has good ductility, toughness and seismic performance, which is suitable for earthquake prone and strong earthquake areas. Under normal coating conditions, it has a long physical life and no shrinkage and creep problems.

Steel box girder is widely used in large Bridges, highways, airports, high-speed rail and other construction fields. In the construction of large highway Bridges, highway Bridges, railway Bridges and other large projects, steel box beams are usually used as the main load-bearing components to meet the needs of bearing capacity and span
