IPE 80
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 IPE 80 steel profile weighs 6.0 kg/m (4.03 lb/ft), has a depth of 80 mm (3.15 in), flange width 46 mm (1.81 in). Cross-sectional area: 742.9 mm². Moment of inertia Ix = 77.7 cm⁴, Iy = 8.47 cm⁴.
