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 457x191x74 steel profile weighs 74.3 kg/m (49.93 lb/ft), has a depth of 457 mm (17.99 in), flange width 190.4 mm (7.50 in). Cross-sectional area: 9,373.6 mm². Moment of inertia Ix = 32,918.98 cm⁴, Iy = 1,670.68 cm⁴.
