Bridges
There are many different elements that are used to create a regular metal bridge, with a number of those elements being used for a specific bridge type only. Some of the more common steel bridge elements are beams, slabs and girders. We can also mention stiffeners, diaphragms, and flanges here, as well. Other components tend to vary quite a lot when it comes to different steel bridge types.
We can safely say that there are three main types of metal bridges that are the most popular nowadays: steel truss, steel arch and steel box girder. Steel truss bridge, for example, is a bridge that is mostly composed with many trusses. It is relatively easy to create, with trusses themselves being easy to manufacture and relatively light in terms of weight. Most of the trusses are connected to each other using triangular shapes, to make sure that the load is distributed and optimized
