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 305x305x240 steel profile weighs 240.0 kg/m (161.28 lb/ft), has a depth of 352.5 mm (13.88 in), flange width 318.4 mm (12.54 in). Cross-sectional area: 30,380.7 mm². Moment of inertia Ix = 63,840.09 cm⁴, Iy = 20,310.03 cm⁴.
