I beams
Flanged structural members
I beams are steel structural supports with an I-shaped cross-section—a vertical web connecting two horizontal flanges.
The shape provides excellent strength-to-weight ratio for bearing loads, making I beams fundamental to building construction and bridge engineering.
Also called H beams or W beams depending on exact proportions.
The skeleton of the skyscraper was all I beams and rivets.
