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 W150x18 steel profile weighs 18.0 kg/m (12.10 lb/ft), has a depth of 153 mm (6.02 in), flange width 102 mm (4.02 in). Cross-sectional area: 1,984.1 mm². Moment of inertia Ix = 768.28 cm⁴, Iy = 101.04 cm⁴.
