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 UB 406x178x60 steel profile weighs 60.1 kg/m (40.39 lb/ft), has a depth of 406.4 mm (16.00 in), flange width 177.9 mm (7.00 in). Cross-sectional area: 7,562.6 mm². Moment of inertia Ix = 21,280.17 cm⁴, Iy = 1,202.69 cm⁴.
