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 914x419x343 steel profile weighs 343.3 kg/m (230.70 lb/ft), has a depth of 911.8 mm (35.90 in), flange width 418.5 mm (16.48 in). Cross-sectional area: 43,231.3 mm². Moment of inertia Ix = 617,045.75 cm⁴, Iy = 39,143.33 cm⁴.
