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 406x140x46 steel profile weighs 46.0 kg/m (30.91 lb/ft), has a depth of 403.2 mm (15.87 in), flange width 142.2 mm (5.60 in). Cross-sectional area: 5,774.7 mm². Moment of inertia Ix = 15,368.99 cm⁴, Iy = 537.74 cm⁴.
