plate girders

Plate girders are large structural beams made from steel plates, assembled by welding or bolting together. They are used in bridges and buildings to support heavy loads, with the steel plates forming the main horizontal supports or "flanges" and vertical webs that hold everything together. Their design allows them to efficiently carry bending and shear forces, providing strength and stability over long spans. Because they can be prefabricated and customized, plate girders are a practical choice for large-scale construction projects requiring durable, reliable support systems.
