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 305x305x97 steel profile weighs 96.9 kg/m (65.12 lb/ft), has a depth of 307.9 mm (12.12 in), flange width 305.3 mm (12.02 in). Cross-sectional area: 12,146.5 mm². Moment of inertia Ix = 21,886.58 cm⁴, Iy = 7,306.06 cm⁴.
