H beam, also known as H-shaped beam or I-beam, is a structural beam commonly used in construction and engineering projects. It is characterized by its H-shaped cross-section, which provides excellent strength and stability for supporting heavy loads. H beams are typically made of steel and are widely used in the construction of buildings, bridges, and other structures where high strength and durability are required. They are also used in the manufacturing of vehicles, machinery, and other industrial applications. H beams are available in various sizes and lengths to suit different project requirements.
