HEA 320
EN — 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 HEA 320 steel profile weighs 97.6 kg/m (65.59 lb/ft), has a depth of 310 mm (12.20 in), flange width 300 mm (11.81 in). Cross-sectional area: 11,811 mm². Moment of inertia Ix = 21,812.23 cm⁴, Iy = 6,976.69 cm⁴.
