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 457x152x82 steel profile weighs 82.1 kg/m (55.17 lb/ft), has a depth of 465.8 mm (18.34 in), flange width 155.3 mm (6.11 in). Cross-sectional area: 10,364.3 mm². Moment of inertia Ix = 36,188.27 cm⁴, Iy = 1,183.97 cm⁴.
