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 254x146x43 steel profile weighs 43.0 kg/m (28.90 lb/ft), has a depth of 259.6 mm (10.22 in), flange width 147.3 mm (5.80 in). Cross-sectional area: 5,427.7 mm². Moment of inertia Ix = 6,477.66 cm⁴, Iy = 677.22 cm⁴.
