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 457x191x82 steel profile weighs 82.0 kg/m (55.10 lb/ft), has a depth of 460 mm (18.11 in), flange width 191.3 mm (7.53 in). Cross-sectional area: 10,358.8 mm². Moment of inertia Ix = 36,650.98 cm⁴, Iy = 1,870.33 cm⁴.
