HEA 120
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 120 steel profile weighs 19.9 kg/m (13.37 lb/ft), has a depth of 114 mm (4.49 in), flange width 120 mm (4.72 in). Cross-sectional area: 2,410 mm². Moment of inertia Ix = 579.57 cm⁴, Iy = 230.5 cm⁴.
