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 457x191x89 steel profile weighs 89.3 kg/m (60.01 lb/ft), has a depth of 463.4 mm (18.24 in), flange width 191.9 mm (7.56 in). Cross-sectional area: 11,287.3 mm². Moment of inertia Ix = 40,614.75 cm⁴, Iy = 2,088.85 cm⁴.
