Plate Girder Bridges – Details and Design Requirements. Plate girders became popular in the late 1800's, when they were used in construction of railroad bridges. The plates were joined together using angles and rivets to obtain plate girders of desired size. By 1950's welded plate girders replaced riveted and bolted plate girders in developed ...
بیشترOur Bridge Building Process is as Simple as Building Blocks. Maybe our title is a little too simplified because actual bridge building is highly technical and requires heavy construction equipment. However, because we at U.S. Bridge have the experience, technology, and equipment, it can be a simple process for the client to embrace.
