AISC — Wide Flange (I-beam)

Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.

The W840x210 steel profile weighs 210.0 kg/m (141.12 lb/ft), has a depth of 846 mm (33.31 in), flange width 293 mm (11.54 in). Cross-sectional area: 26,575.3 mm². Moment of inertia Ix = 306,385.09 cm⁴, Iy = 10,253.46 cm⁴.
