A girder is a large horizontal support beam used to frame buildings and bridges. It is one of the most common structural support systems. Smaller beams transfer their weight-bearing loads onto girders, which then transfers the concentrated load onto the structure’s vertical columns.
All girders are beams, but not all beams are girders. Most horizontal supports in large structures are girders due to their immense size. Girders withstand the heaviest and most dynamic loads, including rolling loads, which make them especially useful in bridge construction where the load amount is not constant.
Both old and new girders support our new office within the Miller Textile building in northeast Minneapolis.
