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 533x210x109 steel profile weighs 109.0 kg/m (73.25 lb/ft), has a depth of 539.5 mm (21.24 in), flange width 210.8 mm (8.30 in). Cross-sectional area: 13,748.1 mm². Moment of inertia Ix = 65,969.6 cm⁴, Iy = 2,941.6 cm⁴.
