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 254x146x31 steel profile weighs 31.1 kg/m (20.90 lb/ft), has a depth of 251.4 mm (9.90 in), flange width 146.1 mm (5.75 in). Cross-sectional area: 3,918.1 mm². Moment of inertia Ix = 4,347.37 cm⁴, Iy = 447.41 cm⁴.
