Quick Summary

An I beam is a structural element used in construction, characterized by its I-shaped cross-section. This shape, consisting of a vertical web and horizontal flanges, is designed for optimal strength and stiffness, allowing it to efficiently carry loads.12

In building construction, beams are horizontal members that span openings, supporting weight from above, such as walls, floors, or roofs. I beams, often made of steel, are a common type of beam because their design concentrates material where stress is greatest, reducing weight while maintaining structural integrity. An H beam is similar to an I beam but features wider flanges.23
