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 UB 533x210x122 steel profile weighs 122.0 kg/m (81.98 lb/ft), has a depth of 544.5 mm (21.44 in), flange width 211.9 mm (8.34 in). Cross-sectional area: 15,401.1 mm². Moment of inertia Ix = 75,190.15 cm⁴, Iy = 3,386.27 cm⁴.
