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 1200x300x16x25 steel profile weighs 262.2 kg/m (176.19 lb/ft), has a depth of 1200 mm (47.24 in), flange width 300 mm (11.81 in). Cross-sectional area: 33,400 mm². Moment of inertia Ix = 720,595.833 cm⁴, Iy = 11,289.253 cm⁴.
