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 356x127x39 steel profile weighs 39.1 kg/m (26.28 lb/ft), has a depth of 353.4 mm (13.91 in), flange width 126 mm (4.96 in). Cross-sectional area: 4,887.6 mm². Moment of inertia Ix = 9,932.12 cm⁴, Iy = 357.53 cm⁴.
