I beam
Flanged structural member
An I beam is a structural support beam with a cross-section shaped like the capital letter I—a vertical web connecting two horizontal flanges at top and bottom.
This shape provides excellent strength-to-weight ratio, making I beams fundamental to construction of buildings, bridges, and other large structures.
Also called an H beam when the flanges are wider.
