AISC — 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 W310x28 steel profile weighs 28.3 kg/m (19.02 lb/ft), has a depth of 309 mm (12.17 in), flange width 102 mm (4.02 in). Cross-sectional area: 3,504.6 mm². Moment of inertia Ix = 5,282.52 cm⁴, Iy = 157.89 cm⁴.
