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 457x152x74 steel profile weighs 74.2 kg/m (49.86 lb/ft), has a depth of 462 mm (18.19 in), flange width 154.4 mm (6.08 in). Cross-sectional area: 9,358.4 mm². Moment of inertia Ix = 32,273.66 cm⁴, Iy = 1,046.05 cm⁴.
