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 305x305x158 steel profile weighs 158.1 kg/m (106.24 lb/ft), has a depth of 327.1 mm (12.88 in), flange width 311.2 mm (12.25 in). Cross-sectional area: 19,938.2 mm². Moment of inertia Ix = 38,384.36 cm⁴, Iy = 12,566.73 cm⁴.
