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 356x406x551 steel profile weighs 551.0 kg/m (370.27 lb/ft), has a depth of 455.6 mm (17.94 in), flange width 418.5 mm (16.48 in). Cross-sectional area: 69,994.8 mm². Moment of inertia Ix = 226,449.64 cm⁴, Iy = 82,658.52 cm⁴.
