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 356x406x340 steel profile weighs 339.9 kg/m (228.41 lb/ft), has a depth of 406.4 mm (16.00 in), flange width 403 mm (15.87 in). Cross-sectional area: 43,105.4 mm². Moment of inertia Ix = 122,054.55 cm⁴, Iy = 46,847.62 cm⁴.
