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 W530x66 steel profile weighs 65.6 kg/m (44.08 lb/ft), has a depth of 525 mm (20.67 in), flange width 165 mm (6.50 in). Cross-sectional area: 8,231.6 mm². Moment of inertia Ix = 34,206.8 cm⁴, Iy = 856.45 cm⁴.
