I-BEAM
I-Beams (fr: Poutre en I): A structural element with an I-shaped cross section, primarily used in construction to withstand loads that are, typically, applied laterally to the beam’s axis. Aside from their different weight-withstanding properties, the visual difference between an I –beam and an H-beam consists in the flange, the I -Beam’s flange has an inclination and the upper and lower surfaces are not parallel.
