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.

Also known as: IPR 310x60 (México) · Doble T 310x60 (Argentina / LATAM) · UB 303 (UK / Australia)

The W310x60 steel profile weighs 60.0 kg/m (40.32 lb/ft), has a depth of 303 mm (11.93 in), flange width 203 mm (7.99 in). Cross-sectional area: 7,394.6 mm². Moment of inertia Ix = 12,507.75 cm⁴, Iy = 1,827.42 cm⁴.
