HEB 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 HEB 320 steel profile weighs 127.0 kg/m (85.34 lb/ft), has a depth of 320 mm (12.60 in), flange width 300 mm (11.81 in). Cross-sectional area: 15,508.5 mm². Moment of inertia Ix = 29,707.18 cm⁴, Iy = 9,228.54 cm⁴.
