Aluminum flat bar (also known as flat stock or rectangle bar) is a non-ferrous, corrosion-resistant, lightweight alternative to steel bar stock widely used in construction, machinery, furniture, aviation, and consumer goods. It is characterized by its rectangular shape and flat, even surfaces and is typically produced by passing a heated aluminum billet through a die to create the desired cross-sectional shape. The resulting flat bar has sharp 90-degree corners and uniform thickness along its length.
