Hot Rolled Universal Beams and Columns , H beams , AS 3679.1 (1996)
Introduction:
H-Beam is another product coming out from our hot rolled mill.It is the structural steel profile shaped like an H in section.The horizontal elements of the "I" are flanges,while the vertical element is the web.The web resists shear forces while the flanges resist most of the bending moment experienced by the beam.Beam theory shows that the H-shaped sections is a very efficient form for carrying both bending and shear loads in the plane of the web.
