CISC, welded sections · 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 I 1400x400x16x30 steel profile weighs 356.7 kg/m (239.70 lb/ft), has a depth of 1400 mm (55.12 in), flange width 400 mm (15.75 in). Cross-sectional area: 45,440 mm². Moment of inertia Ix = 1,447,133.867 cm⁴, Iy = 32,045.739 cm⁴.
