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 W250x25 steel profile weighs 25.3 kg/m (17.00 lb/ft), has a depth of 257 mm (10.12 in), flange width 102 mm (4.02 in). Cross-sectional area: 3,178.8 mm². Moment of inertia Ix = 3,353.08 cm⁴, Iy = 149.02 cm⁴.
