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 W690x125 steel profile weighs 125.0 kg/m (84.00 lb/ft), has a depth of 678 mm (26.69 in), flange width 253 mm (9.96 in). Cross-sectional area: 15,799 mm². Moment of inertia Ix = 116,511.58 cm⁴, Iy = 4,408.06 cm⁴.
