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 W250x45 steel profile weighs 44.8 kg/m (30.11 lb/ft), has a depth of 266 mm (10.47 in), flange width 148 mm (5.83 in). Cross-sectional area: 5,672 mm². Moment of inertia Ix = 7,038.61 cm⁴, Iy = 703.27 cm⁴.
