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 W250x18 steel profile weighs 17.9 kg/m (12.03 lb/ft), has a depth of 251 mm (9.88 in), flange width 101 mm (3.98 in). Cross-sectional area: 2,224.5 mm². Moment of inertia Ix = 2,171.74 cm⁴, Iy = 91.23 cm⁴.
