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 UC 356x406x634 steel profile weighs 633.9 kg/m (425.98 lb/ft), has a depth of 474.6 mm (18.69 in), flange width 424 mm (16.69 in). Cross-sectional area: 80,556.6 mm². Moment of inertia Ix = 274,356.59 cm⁴, Iy = 98,110.25 cm⁴.
