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 406x178x67 steel profile weighs 67.1 kg/m (45.09 lb/ft), has a depth of 409.4 mm (16.12 in), flange width 178.8 mm (7.04 in). Cross-sectional area: 8,464.7 mm². Moment of inertia Ix = 24,014.78 cm⁴, Iy = 1,364.51 cm⁴.
