A girder is a beam that is used in bridges and buildings as the main horizontal support. It can be of wood, reinforced concrete, steel and in the case of an iron girder, of iron. A girder is the main horizontal beam; any additional beams mostly pass perpendicularly from the girder. Most girders are given a cross section I beam for strength.
In terms of construction engineering the girder performs the function of carrying the heavy traverse load. It performs the function of transferring the load resting on it into the columns. In any floor system the different joists and beams transfer their load onto the girders and this in its turn distributes its load onto the columns. Since it performs such a crucial function in architecture it is necessary for it to be strong and tensile. Hence it is mostly of iron, steel, concrete etc.
