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 203x203x71 steel profile weighs 71.0 kg/m (47.71 lb/ft), has a depth of 215.8 mm (8.50 in), flange width 206.4 mm (8.13 in). Cross-sectional area: 8,953.4 mm². Moment of inertia Ix = 7,548.32 cm⁴, Iy = 2,536.78 cm⁴.
