A girder is a large, horizontal structural beam used in construction to support heavy loads and provide stability to a building or bridge. Typically made from steel, concrete, or wood, girders are crucial for transferring weight from the roof, floors, or other structural elements down to the columns or supports below. They are often placed at regular intervals within a framework to create a strong and secure foundation for additional construction. Girders can vary in size and shape, depending on the specific engineering requirements, and play an essential role in ensuring the overall strength and safety of a structure.
