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 254x146x37 steel profile weighs 37.0 kg/m (24.86 lb/ft), has a depth of 256 mm (10.08 in), flange width 146.4 mm (5.76 in). Cross-sectional area: 4,667 mm². Moment of inertia Ix = 5,470.75 cm⁴, Iy = 570.52 cm⁴.
