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 457x191x98 steel profile weighs 98.3 kg/m (66.06 lb/ft), has a depth of 467.2 mm (18.39 in), flange width 192.8 mm (7.59 in). Cross-sectional area: 12,437 mm². Moment of inertia Ix = 45,326.59 cm⁴, Iy = 2,346.42 cm⁴.
