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 356x368x129 steel profile weighs 129.0 kg/m (86.69 lb/ft), has a depth of 355.6 mm (14.00 in), flange width 368.6 mm (14.51 in). Cross-sectional area: 16,235.2 mm². Moment of inertia Ix = 39,757.17 cm⁴, Iy = 14,609.73 cm⁴.
