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 HEM 120 steel profile weighs 52.1 kg/m (35.01 lb/ft), has a depth of 140 mm (5.51 in), flange width 126 mm (4.96 in). Cross-sectional area: 6,517 mm². Moment of inertia Ix = 1,990.99 cm⁴, Iy = 701.73 cm⁴.
