HEB 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 HEB 120 steel profile weighs 26.7 kg/m (17.94 lb/ft), has a depth of 120 mm (4.72 in), flange width 120 mm (4.72 in). Cross-sectional area: 3,277 mm². Moment of inertia Ix = 837.79 cm⁴, Iy = 317.02 cm⁴.
