A wedge plate is a structural component used to join two structural members together at an angle. It is a type of plate that has a wedge-shaped cross section, with the thicker section being on one end and the thinner section on the other. The angle of the wedge can be either right or oblique. The wedge plate is typically bolted or welded onto the two members, creating a strong connection between them. Wedge plates are commonly used in the construction of bridges, buildings, and other structures.
