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 356x127x33 steel profile weighs 33.1 kg/m (22.24 lb/ft), has a depth of 349 mm (13.74 in), flange width 125.4 mm (4.94 in). Cross-sectional area: 4,123.8 mm². Moment of inertia Ix = 8,010.04 cm⁴, Iy = 279.96 cm⁴.
