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 W250x73 steel profile weighs 73.0 kg/m (49.06 lb/ft), has a depth of 253 mm (9.96 in), flange width 254 mm (10.00 in). Cross-sectional area: 9,145.2 mm². Moment of inertia Ix = 11,108.07 cm⁴, Iy = 3,879.46 cm⁴.
