An H-Beam, also known as an H-section or I-beam, is a structural steel beam shaped like the letter "H" when viewed from the end. It consists of two horizontal flanges connected by a vertical web, providing high strength and stability. H-Beams are commonly used in construction and engineering for building frameworks, bridges, and other structures due to their ability to support heavy loads. The design of H-Beams allows for efficient use of materials, making them lighter than solid beams while maintaining strength. They are often made from steel and can be found in various sizes to accommodate different structural requirements.
